ACCORDINGLY, gravity/acceleration involves BALANCED inertia/INERTIAL RESISTANCE; AS E=mc2 IS F=ma; AS the rotation of WHAT IS THE MOON then NECESSARILY matches it's revolution; AS ELECTROMAGNETISM/ENERGY IS GRAVITY. Gravity IS ELECTROMAGNETISM/energy. E=mc2 IS F=ma. THE MOON is thus a frozen/constant or "dead"/unchanging form in perpetual motion as necessitated by the Earth/Sun BALANCE that fundamentally governs and generally shapes it IN ACCORDANCE WITH the UNIVERSAL fact that E=mc2 IS F=ma. GREAT. I have mathematically explained or proven why there is NO RESISTANCE regarding WHAT IS THE MOON in BALANCED RELATION to the Sun AND the Earth, AS E=mc2 IS F=ma; as this CLEARLY then explains the perpetual motion of WHAT IS THE MOON. Alas, gravity AND ELECTROMAGNETISM/energy are linked AND BALANCED opposites; AS E=mc2 IS F=ma; AS ELECTROMAGNETISM/ENERGY IS GRAVITY. "Mass"/ENERGY is gravity. ELECTROMAGNETISM/energy is gravity. I have explained why objects fall at the SAME RATE (neglecting air resistance, of course), as ELECTROMAGNETISM/energy is gravity. Gravity IS ELECTROMAGNETISM/energy. It ALL CLEARLY makes perfect sense. Beautiful. E=mc2 IS F=ma. THE EARTH/ground is E=mc2 AND F=ma IN BALANCE, as this CLEARLY then also explains why we do not feel the rotation of WHAT IS THE EARTH. Alas, what is THE MOON is a linked AND BALANCED opposite in relation to the Earth AND what is the Sun; AS E=mc2 IS F=ma; AS ELECTROMAGNETISM/energy is gravity. Accordingly, the Moon remains the same (or basically constant) insofar as it's rotation necessarily matches it's revolution. Indeed, the SPACE that the Moon occupies is understood as being FULLY formed/manifest. The motion of the Moon (thus defined) FIXES, defines, or encompasses RELATIONAL motion. The relationally VARIABLE EXPERIENCE of what is THE EARTH/ground is thus directly comparable to what is then understood as the INVARIANT form of what is the Moon (ON BALANCE), AS E=MC2 IS F=MA.

WHY ELECTROMAGNETISM/ENERGY IS GRAVITY: Gravity/acceleration involves balanced inertia/inertial resistance, as ELECTROMAGNETISM/energy is gravity. This is consistent WITH F=ma AND E=mc2, as gravity IS ELECTROMAGNETISM/energy. So, inertia/inertial resistance is proportional to (or balanced with/as) gravitational force/energy; as this balances AND unifies ELECTROMAGNETISM/energy AND gravity; as this balances gravity AND inertia. In other words, GRAVITATIONAL force/energy is proportional to (or balanced with/as) inertia/inertial resistance; as ELECTROMAGNETISM/energy IS gravity. Accordingly, gravity/acceleration involves balanced inertia/inertial resistance; as gravity IS ELECTROMAGNETISM/energy. It is proven.

Hello Sabine, I got your book Lost in Math as a Christmas present, so far I'm really enjoying the read and your writing style (in particular your humor). I'd like to say thank you for inspiring me (someone who's still in school, but plans to go into physics) and many others.
Love your handle, mate. Classic. Best wishes with your learning. Sabine should write college courses. Humour is a sorely underrepresented area of education!
I have been exposed to radiation in high doses, additionally my x wife also. My x wife developed Graves disease as mentioned by Sabina here, and she did take the radioactive Iodine pill and it worked flawlessly. On a side note, they typically give you the option of actual surgery to remove portions of your thyroid gland however this surgery is very risky and has potential of significant morbidity. I had a very large pituitary tumor that surgery was unsuccessful at removing and so I had radiation treatment to render it inert. The technical term for the treatment I received was fractionated stereotactic radiotherapy treatments over 30 days once per day. I will say, if you are exposed to beams of proton radiation in your head you can feel it hitting you and it manifests as a bright blue light, sorta like a cross between the blue of lightning and a tanning bed. When I received a blast of this radiation I could feel it hitting my forehead or the top of my head or back like someone pointing a garden hose at me with blue light pouring out. The oncologist explained to me that an outside observer does not see the light , it's the radiation hitting my optic nerves and "inducing" the perception of bright blue light. the treatment I received was from a system called Novalis Tx and it saved my life.
while I was being treated with radiation I was given high doses of steroids, Prednisone, to combat the swelling of my brain. after it was completed most of my hair grew back except for a round spot sorta in top back but not in the normal spot men lose their hair at. for about 2 years after I experienced face blindness, loss of long term memory, adrenal insufficiency crisis and behavioral changes. My pituitary is basically a empty husk laying at the bottom of the sella turcica so I must take all the hormones normally induced by the gland, thyroid, cortisone, testosterone. I struggle with depression and pain as replacement of cortical steroids orally doesn't come close to how the body manages it via the HPA axis. The years of having a bi producing tumor over 3 cm caused me to have metabolic syndrome and type 2 diabetes, but surprisingly my eyesight is intact with no noticeable damage to my optic nerves.
Sabine, thank you for your nice explanation. I am a physicist, and what immediately caught my attention (I almost spilled my coffee) is your definition of radiation as "energy transfer by waves or particles". Actually, I never bored to define for myself what "radiation" exactly means, because every time it is clear from the context what I am dealing with (sometimes to remove the ambiguity we use word "radiation" in combination with other words like "electromagnetic radiation", "acoustic radiation"). But, if we decide to define radiation, I would exclude "particle" from this definition. Otherwise, you cannot distinguish between radiation and convection, or you have to admit, that electric current is radiation (because in both cases energy is transferred by particles). We do not want to climb this rabbit hole.
I was surprised by this definition too. Tbh I had always assumed radiation was a shorthand for electromagnetic radiation in most context. And occasionally it also included fast moving individual particles like cosmic rays, alpha particles, etc. Then I googled the definition and it doesn't seem very consistent 😂
Sabine, thank you very much. You’re a brilliant communicator and it’s always a pleasure to learn from you. I appreciate your deep knowledge and your critical thinking.
I discovered your chanel just now and I'm in love with it, I'm already two days straight watching many videos I always had curiosity to know about and always thought "why no one explain this?" And here you are, explaining so much, so scientifically, your uses of logic are amazing, thank you so much for your videos
13:20 *Radiation hormesis* sounds like a variant of "what doesn't break you makes you stronger." That idea works in many other cases-vaccines, physical exercise, tanning-up to a point. But it's too easy to get over-motivated, push boundaries, and end up with paralytic poliomyelitis, torn muscles, and carcinoma. Playing around with radiation is particularly dangerous. Talking about (nuclear) radiation or nuclear energy always causes a strong reaction in me. Images of Marie Curie, Eben Byers, Richard Feynman, Litvinenko, Chernobyl, Fukushima, Hanford Site etc. flash in front of my eyes forcefully and involuntarily. You can be sure I'm going to remain very, very skeptical of radiation hormesis-I may never trust it in my lifetime.
@@doomedtolinger2213 nah, no damages here. I wasn't actually drinking my coffee near my phone at the time of seeing it, so no harm, no foul. But I _did_ happily give you a like for it!
Excellent video. You can mention in future videos few supporting experiments for the theories. For example :"This is how to measure Total Ionizing Dose.... This is how to measure heavy ions impact.... This is how NOT to detect Higgs bosons" ;)
I am relatively new to your channel and I want to say how much I appreciate the videos you make. I love science but I am not well educated in it. I appreciate your genius of being able to simplify subjects - but not TOO simple. Really, your work is just perfect for someone like me. Thanks
Hi Sabine!!! I want to express two things: firstly I really appreciate your teachings in Physics. I’ve been involved because of my studies with a certain amount of physics in the past and I eagerly follow some scientists to learn a little more about our Universe. Secondly I saw your video about Speaking English and I can say that I really like to hear you speaking!!! It’s a neutral accent and I, being for Argentina and having Spanish as my mother tongue, really appreciate each and every word you speak. And believe me, I can cope with English without any problem but I’m far away from an educated English speaking person, but you DON’T have a single mistake! It’s really a pleasure watch your videos just for knowledge of both, science and English. Thank you! I really admire you!!!! Kisses from Argentina!!!
Agree with the Great Courses recommendation. I have gotten several and the one that impressed me most was "Thermodynamics: Four Laws That Move the Universe". (There are probably many others worth viewing.)
7:38 the sounds cuts in the last part of the sentece, what did i miss? ..."also cause"... I so like how you present and the down to earth way you are able to present all these subjects, i so wished you where my teacher 25 years ago.
Very interesting as usual. Were there any studies on pilots, astronauts or communities living at high altitudes in relation to longer term exposure to higher levels of ionizing radiation?
Does not matter if a video gets likes or dislikes, the algorithm treat them both as a social engagement and will promote the video based on the absolute engagement (up+down). So if someone really really hated a video they should not comment and not down vote :-) knowing this makes me smile every time I see people down vote a great video.
As always, great stuff Sabine! I would like to add however that radiation in the microwave spectrum may not be ionizing, but they can affect protein conformation and thus alter enzymatic activity, receptors, and therefore metabolism. This is a potential issue for 5G systems.
Good job of explaining radiation. You are correct about the complexity of radiation safety. I was the radiation safety officer for three companies. While you can predict the effects of an acute high level exposure long term effects of an exposure for an individual is unpredictable, yet statistically significant for a group of individuals receiving a similar dose. Probably the worst thing for an individual is a long term low level dose from an ingested substance. Smoking is one such ingestion mechanism. Radon in the smoke is deposited in the lungs as a radioactive isotope of lead. Body tissues are exposed continuously to low level radiation, many individuals then develop lung cancer. And that is an over simplification. I have seen the whole body radiation counts for smokers, their lungs "glow" bright!!
I like that new animations and effects! The overall quality of your videos gets better and better every time! Can't wait for more people to be interested in your content :)
Two people in my life made me love science...Nancy Comer (9th grade Physical Science teacher) and Sabine (just wow, she is amazing). Without question, I would listen to her discuss cookie recipes or the table of contents from boring books.
Since we're on the topic of radiation - can you recommend any sources about whether using vintage radioactive camera lenses like the Super Takumar 50mm f1.4 would cause damage in the long term? I'd assume not since the camera body would probably block a lot of the radiation emitting from the rear of the lens, but we don't have any sources from actual scientists online - just people with cheap amazon bought pocket Geiger counters.
It’s a delight to listen to Dr. Hossenfelder. The density and clarity of her expression is unique on RUclips. Such a beautiful way to learn about science and the martial art of argumentation at the same time.
It wasn't until my classes in modern physics, electromagnetism, etc. that a lot of physical concepts became clear, or at least somewhat tolerable. Thanks Sabine for all the refreshers!
When they hear the word radiation, they hear radioactivity...and then panic.😅 If you express radiating ripples on the surface of water as radiation, they'll panic.
The N word (nuclear) has the same effect. They think of bombs destruction and death, which in turn "justify" to reject nuclear energy. For the most part their education truly failed them.
07:02 There is little slip in the graph. Ionized molecule can also have extra electron (in case of radiolysis). So, "lack electrons" is not always true.
She has already done a video about cell phones and 5G. Basically, the answer is don't worry about it. So long as you don't climb any fences that are designed to keep you away from things, it isn't a hazard.
Sound is often referred to as radiation by sound engineers. They talk about how speaker cabinets ‘radiate’ the sound. In multiple speaker arrangements the polar patterns resemble those of the double slit experiment.
Thanks a lot, Ms. Sabine. I was wondering that If it is possible for you to make a video about Geiger counters and measurement quantities such as sievert and rem.
@@SabineHossenfelder I would suggest getting an RF meter that can measure 4g/5g. Place it up to the glass of a running kitchen microwave and then place it against your cell phone and make a call. I am getting about the same reading on a 4g phone and a 1200 watt running microwave. I think you will find much more to be worried about using an RF meter than using a Geiger counter.
@@melgibson6331 Geiger counters measure ionising radiation, mainly beta particles and to a lesser degree alpha particles and gamma rays (which are high-energy EM waves). The "radiation" used in radio and so-called "microwaves", including the transmissions from 4G and 5G networks are below the infra-red band and only cause heating, not ionisation. A GM counter will register nothing from these. On the other hand, an X-ray will set a GM counter screaming! Sound is another form of "radiation" which simply means some form of energy spreading outwards. The engineers who work with RF circuits and high-power microwave devices like radar antennae have no health problems whatsoever, the greatest risk being a burn.
@@SabineHossenfelder Start with ionisation chambers, they are much simpler devices and measre directly the ionising effect of radiation. The downside is that the output can be as low as a few thousand electrons per second, but this is not very difficult to measure. GM tubes are great but their operation is quite complex.
Regarding radiation hormesis, I know lots of radiation scientists, and as far as I'm aware, nobody exposes himself to radiation on purpose in order to increase his resistance to it. The idea makes sense in principle, and I remember I've seen some evidence in in-vitro experiments, but most of the evidence is cirmustantial, based on statistics of the health of people who are professionally exposed to radiation. The issue is that correlation doesn't imply causality. For instance, they may be healthier simply because they are subject to strict periodic medical check-ups, and this may help to detect illness at an early stage and treat them. It may also help to remove from the group those who are unhealthy.
Very interesting and explained well. My question is in knowing that our magnetic fields weakening and not shielding us from harmful cosmic rays, is this concerning?
No. Because the Earth magnetic field don't stop the cosmic rays. The atoms in the atmosphere does, crashing with them and producing particle showers(look the video again, Sabine mentions this) Now, the solar wind with his charged plasma is another issue, of course...
One thing that came through loud and clear (very clear) on this and another related video on 5G is the two mechanisms of energy transfer from EM waves/particles - quantum energy levels that can damage specific molecular structures because they are 'matched' to the energy levels of EM quanta and heating as a function of power levels. A question that still puzzles me though is the effect of pulsed systems with very high peak pulse power and very low average power. For instance, a marine radar magnetron can have a peak power of 20kW and an average power of 20W. The 20W will obviously heat tissue close up but will the high peak power have any effect? I don't know! Anyone else?
For radio waves what matters is the total energy deposited into tissues which results in heat, and which tissues absorb them. The total energy is related to the average power. Pulsed sources can have very high peak power but much lower average power. So long as the peak duration is short enough that the tissues don't have time to heat up significantly during one pulse, then all that matters is the average power. Radar transmitters use highly directional antennas that concentrate that average power into a very narrow beam. You wouldn't notice 20W of energy deposited over your entire body. But 20W deposited into a small area would cook the tissues. Think of it like a candle flame. You can't feel anything if you're standing next to a lit candle as its radiated energy is being spread over your entire body. But stick your hand into the flame so the energy is concentrated into a small spot, and you'll certainly notice it (and be cooked by it). A single candle flame is coincidentally also about a 20W average emitter. So for the marine radar, if you're far enough away that the diverging beam covers an area bigger than your whole body it isn't a big deal. But if you're standing right in front of the antenna so that the beam is only hitting a small area, that's a problem.
Sabine, you have done a great service in educating the public on topics in physics and astronomy, in which you are an expert. If you take the time to educate yourself, you may also be a valuable resource on epidemiology. But there are unexpected biological effects and a great deal of commercial influence over the science, so you have to read carefully to see the big picture. Radiation hormesis is real, though it has been made "controversial" by politics. And the most important biological effect of cell phone radiation is throuh voltage-gated calcium channels. Please read about this so you can serve the great number of us who have put our faith in you.
I have measured gravity, and performed radiography, on the Arctic Coastal Plain, of Alaska. We used Cobalt, for our source. When I was hired to do a gravity profile, I did not know, gravity was measured. I just told the interviewer I had done it before. I read the manual on the flight to Barrow, and worked there three years. I never really understood what gravity is, but completed my tasks. We used a helicopter in Summer and a track vehicle in Winter. I worked alone in Winter. Lovely, Northern Lights, which are charged particles as well, interactions are in the atmosphere. Lovely, to view, in the Arctic mirrored in the Antarctic.
Antioxidants (like are found in fruit) are chemicals which help protect your DNA from oxidization and oxidants (like charcoal) increase the rate of oxidization. Oxidization damages the DNA and can increase the risk of cancer in healthy people. However studies have also found that antioxidants can also unfortunately protect DNA which is already cancerous. Essentially they are good if you don't have cancer, but aren't so good if you do. They're not ionizing radiation levels of harmful but you shouldn't be eating burnt meat all the time.
@@eljcd No, you very much need to breathe Oxygen. I am talking about DNA oxidization: en.wikipedia.org/wiki/DNA_oxidation Another definition of 'Oxidization' is "To increase the positive charge or valence of (an element) by removing electrons", which is what DNA Oxidization is: www.thefreedictionary.com/oxidization

Lovely video but you failed to mention two common things people should hear. 1. Some exposure to sunlight is desirable. Sunlight causes the body to generate Vitamin D. Many people in northern latitudes are deficient in vitamin D, especially during the winter. 2. Photons with a wavelength greater than 100nm (UV-C) are non-ionizing. They don't have the energy to damage molecules directly. That means optical light, infrared light, microwaves, cell phone signals, and other radio emissions are non-ionizing. Any photon source can cause harm in large enough quantities, but the mainly through heating. A microwave is a heat lamp that emits lower power photons on a longer wavelength that we cannot see. Cell phones emit lower power photons than a keychain LED flashlight. I really enjoy your videos. After recently discovering this channel I have been watching your older content almost daily.
I really like videos like this that carefully define terms and connect them to the salient points necessary to understand a topic. Great job! I am currently radiating happiness. Thanks
Recently I learned that photons are particles which carry X-ray - gamma radiation. So is it as well photon which is produced in magnetron in microwave oven? Is it photon which is used to broadcast radio?
I noticed you cut out what you were going to say about some air purifiers creating ozone. I really wanted to hear about that 😔 because I was curious how healthy my "ionizing" air filter is.
Estimating radiation exposure can be very difficult to do in a meaningful way. For example, suppose you have a block of radium in your living room, in a sealed capsule. Most radium atoms, from the most common sources, are alpha emitters, so almost any container would protect you from any direct radiation. The process produces radon, but this is an inert gas, and with good ventilation would not have little exposure to that, either. OTOH if you ingest radium, almost every alpha particle from decays will deposit its full energy in your body, so that could be very dangerous. If it's in your bones, it will probably stay there, which is even worse. So the environmental circumstances make huge differences in risk.

ALSO consider this: E=mc2 is DIRECTLY and fundamentally derived from F=ma, AS E=mc2 IS F=ma; AS time DILATION proves that electromagnetism/ENERGY IS GRAVITY. THE UNIVERSAL AND MATHEMATICAL PROOF THAT ELECTROMAGNETISM/ENERGY IS GRAVITY: Energy has/involves GRAVITY, AND ENERGY has/involves inertia/INERTIAL RESISTANCE. "Mass"/ENERGY IS GRAVITY. ELECTROMAGNETISM/ENERGY IS GRAVITY. E=mc2 is DIRECTLY and fundamentally derived from F=ma. GRAVITATIONAL force/ENERGY IS proportional to (or BALANCED with/as) inertia/INERTIAL RESISTANCE, AS ELECTROMAGNETISM/ENERGY IS GRAVITY. SO, gravity/acceleration involves BALANCED inertia/INERTIAL RESISTANCE consistent with/as what is BALANCED electromagnetic/gravitational force/ENERGY; AS ELECTROMAGNETISM/ENERGY IS GRAVITY. "Mass"/ENERGY involves BALANCED inertia/INERTIAL RESISTANCE consistent with/as what is BALANCED electromagnetic/gravitational force/ENERGY, AS ELECTROMAGNETISM/ENERGY IS GRAVITY. Gravity AND ELECTROMAGNETISM/ENERGY are linked AND BALANCED opposites, AS ELECTROMAGNETISM/ENERGY IS GRAVITY. THE SUN AND THE EARTH are described and represented by BOTH F=ma AND E=mc2. F=ma AND E=mc2 PROVE that ELECTROMAGNETISM/ENERGY IS GRAVITY, AS ALL of SPACE is NECESSARILY electromagnetic/gravitational (IN BALANCE). Objects fall at the same rate (neglecting air resistance, of course), AS the SPEED OF LIGHT is RELATIVELY CONSTANT AS WELL. ELECTROMAGNETISM/ENERGY IS GRAVITY. Gravity IS ELECTROMAGNETISM/ENERGY. In fact, the rotation of THE MOON MATCHES it's revolution; AS gravity/acceleration involves BALANCED inertia/INERTIAL RESISTANCE; AS ELECTROMAGNETISM/ENERGY IS GRAVITY. So, THE PLANETS (INCLUDING WHAT IS THE EARTH) are not "falling" in what is "curved SPACE" in RELATION to what is THE SUN. This is nonsense. E=mc2 is DIRECTLY AND FUNDAMENTALLY DERIVED FROM F=ma. This truly explains PERPETUAL MOTION. Very importantly, outer "space" involves full inertia; AND it is fully invisible AND black. The stars AND PLANETS are POINTS in the night sky. A PHOTON may be placed the center of THE SUN (as A POINT, of course), as the reduction of SPACE is offset by (or BALANCED with) the SPEED OF LIGHT; AS ELECTROMAGNETISM/ENERGY IS GRAVITY. By Frank DiMeglio EINSTEIN NEVER UNDERSTOOD PHILOSOPHY, MATHEMATICS, AND PHYSICS, AS HE HAS BEEN TOTALLY OUTSMARTED BY SIR FRANK MARTIN DIMEGLIO: The balance of being AND EXPERIENCE is ESSENTIAL. BALANCE AND completeness go hand in hand. THE SELF represents, FORMS, and experiences a COMPREHENSIVE approximation of experience in general by combining conscious and unconscious experience. MOREOVER, the ability of THOUGHT to DESCRIBE OR RECONFIGURE sensory experience is ULTIMATELY dependent upon the extent to which THOUGHT IS SIMILAR TO sensory experience. THOUGHTS ARE INVISIBLE. Dream experience is/involves true/real QUANTUM GRAVITY, AS ELECTROMAGNETISM/ENERGY IS GRAVITY. MOST IMPORTANTLY, in dreams, BODILY/VISUAL EXPERIENCE is invisible AND VISIBLE IN BALANCE. IMPORTANTLY, dream experience is possible/potential AND actual IN BALANCE. THE EYE is ALSO the body. Dreams improve upon memory AND UNDERSTANDING. Indeed, there is no outsmarting the GENIUS of dreams. OVERLAY what is THE EYE in BALANCED RELATION to/with what is THE EARTH. NOW, get a good LOOK at what is the translucent, SEMI-SPHERICAL, QUANTUM GRAVITATIONAL, AND BLUE sky. Excellent. The DOME of a person's EYE is ALSO VISIBLE. THE EARTH IS also BLUE (as water). F=ma AND E=mc2 PROVE that, why, and how ELECTROMAGNETISM/ENERGY IS GRAVITY. This NECESSARILY represents, INVOLVES, and describes what is possible/potential AND actual IN BALANCE. SO, it is NECESSARILY a matter of precisely how these equations are understood in a BALANCED, EXTENSIVE, AND INTEGRATED fashion in RELATION to/with WHAT IS THOUGHT. The INTEGRATED EXTENSIVENESS of THOUGHT (AND description) is improved in the truly superior mind. E=mc2 is DIRECTLY and fundamentally derived from F=ma. Very importantly, outer "space" involves full inertia; AND it is fully invisible AND black. The stars AND PLANETS are POINTS in the night sky. A PHOTON may be placed at the center of THE SUN (as A POINT, of course), as the reduction of SPACE is offset by (or BALANCED with) the SPEED OF LIGHT; AS ELECTROMAGNETISM/ENERGY IS GRAVITY. Get a good LOOK at what is THE EYE. POINTS are points. Gravity IS ELECTROMAGNETISM/ENERGY. ELECTROMAGNETISM/ENERGY IS GRAVITY. GRAVITATIONAL force/ENERGY IS proportional to (or BALANCED with/as) inertia/INERTIAL RESISTANCE, AS ELECTROMAGNETISM/ENERGY IS GRAVITY. "Mass"/ENERGY involves BALANCED inertia/INERTIAL RESISTANCE consistent with/as what is BALANCED electromagnetic/gravitational force/ENERGY, AS ELECTROMAGNETISM/ENERGY IS GRAVITY. Gravity/acceleration involves BALANCED inertia/INERTIAL RESISTANCE, AS ELECTROMAGNETISM/ENERGY IS GRAVITY. "Mass"/ENERGY IS GRAVITY. ELECTROMAGNETISM/ENERGY IS GRAVITY.

F=ma AND E=mc2 PROVE that ELECTROMAGNETISM/ENERGY IS GRAVITY, AS ALL of SPACE is NECESSARILY electromagnetic/gravitational IN BALANCE; AS ELECTROMAGNETISM/ENERGY IS GRAVITY. GREAT. The stars AND PLANETS are POINTS in the night sky. OPEN your EYES. NOW, LOOK at what is the FLAT, SETTING, AND ORANGE SUN (with the SPACE around it THEN going invisible AND VISIBLE IN BALANCE). This ORANGE SUN manifests or forms at what is EYE LEVEL/BODY HEIGHT as well. This ORANGE SUN is manifest ON BALANCE as what is NECESSARILY the BODILY/VISUAL EXPERIENCE of THE EARTH/LAVA. The viscosity of LAVA IS BETWEEN what is manifest as WATER AND THE EARTH/GROUND. ALL of SPACE is NECESSARILY electromagnetic/gravitational IN BALANCE, AS ELECTROMAGNETISM/ENERGY IS GRAVITY. F=ma AND E=mc2 do provide absolute, BALANCED, THEORETICAL, and CLEAR proof that ELECTROMAGNETISM/ENERGY IS GRAVITY. Gravity/acceleration involves BALANCED inertia/INERTIAL RESISTANCE, AS ELECTROMAGNETISM/ENERGY IS GRAVITY. THEREFORE, the rotation of THE MOON MATCHES it's revolution. MOREOVER, a given PLANET (INCLUDING WHAT IS THE EARTH) sweeps out equal areas in equal times; AND this is THEN consistent with/as what is F=ma, E=mc2, AND what is PERPETUAL MOTION; AS ELECTROMAGNETISM/ENERGY IS GRAVITY. It ALL makes perfect sense. BALANCE AND completeness go hand in hand. THE PLANETS (INCLUDING WHAT IS THE EARTH) are NOT "falling" in what is "curved SPACE". In fact, this is nonsense. It is PROVEN.

Small amounts of radiation are generally preferred; Yes, I definitely prefer my intake of infrared radiation to be in the range of 19-21°C. and not like Venus or Mars!
I remember reading a case study from the 70s that said low frequency power lines are harmful to health and can cause depression and dullness, esp in children. Powerlines that are overhead and buried (not too deep) underground.
Good point! That same studied concluded that when cities are developing, the areas where power lines converge into transformer stations are often less desirable areas for luxury housing. So, what happens is that low-price housing or council estates are built near these areas of powerlines and transformer stations and it appears that the people living in those houses are on lower incomes and perhaps do not spend as much on education and health care. A similar case exists for land prone to flooding - it will have a lower value and attracts low-priced housing or caravan parks, so when a flood occurs it is the same demographic group that is affected. It is the politicians and developers who deserve the blame for this problem, not the power lines!
Thank you, Sabine! Radiation hormesis is exactly the term I needed to explain the difference between a younger and older stellar environment. I believe that as our Sun and Earth age there will be less radiation hormesis. I predict there will be less of a variety of living beings but the ones currently inhabiting the planet will become more stable and be able to have longer life spans. Radiation hormesis is a type of stimulation the can produce mutation but is also degrading to life. Good for a young solar system but is less ideal for a mature solar planet.
imagine we could see all of the EM waves that are emitted all around us. What a bright world that would be. I think that would definitely make radio a very interesting thing. AM modulated radio would be like a super bright beacon that dims and brightens regularly and FM would look like a super bright light rapidly and regularly changing colors. Man that would be cool.
It would be beneficial to explain the difference between radioactive contamination and nuclear radiation. Journalists tend to equate the two whenever they write about nuclear power accidents.
An outstanding overview -- I am happy I subscribed on Patreon Systematic, clear, simple, with high integrity -- a delight in form and content Thank you and -- with deep respect for your work !
Let us try this an object that is radio active assume (what) uranium when it decays what particles does it emit and why does lead negate exposure (via particle and wave)?
According to Wikipedia, roughly 90% of cosmic rays are protons, 9% are alpha particles, and only 1% are electrons. Is the earth and its atmosphere becoming continuously more positively charged? If not, what counter-balances all the positively charged cosmic rays?

Biochemist here, this is all accurate. Sabine, I particularly appreciated your methodical approach to this subject: clear and concise, with just enough perspective and nuance. Good work!
You brought up that some cosmic rays still get through the O3 layer. Some places have little O3 above them, ozone hole affected regions. Do you would think people would live longer if society moved underground?
the way waves are always shown really bother me, like I assume the single wave shown is not the only one. do they radiate in all directions available? are all exiting waves in the same orientation as the example slice?
You have sparked an interest in science. Science is truly amazing.
WHY THE OVERALL SHAPE AND BASICALLY CONSTANT FORM OF WHAT IS THE MOON GENERALLY MANIFEST AS SUCH PURSUANT TO THE UNIVERSAL FACT THAT E=MC2 IS (AND MUST BE) F=MA:
Very importantly, outer "space" involves full inertia; AND it is fully invisible AND black. BALANCE and completeness go hand in hand. INSTANTANEITY is FUNDAMENTAL to what is the FULL and proper UNDERSTANDING of physics/physical EXPERIENCE. Ultimately and truly, TIME is NECESSARILY possible/potential AND actual IN BALANCE; AS E=mc2 IS F=ma; AS ELECTROMAGNETISM/ENERGY IS GRAVITY. GREAT !!!!! Time DILATION ULTIMATELY proves ON BALANCE that E=mc2 IS F=ma, AS ELECTROMAGNETISM/energy is gravity. SO, the Earth is fully time dilated ON BALANCE. What is the Earth, what is the Sun, and what is the Moon are governed by E=mc2 AND F=ma IN BALANCE in accordance with the necessary condition that this does then involve what is possible/potential AND actual IN BALANCE. What is the Moon is moving AND not moving (IN BALANCE) in relation to both the Sun AND the Earth, as invisible AND VISIBLE SPACE in fundamental and UNIVERSAL EQUILIBRIUM and balance explains why E=mc2 IS F=ma; as ELECTROMAGNETISM/energy is gravity. ACCORDINGLY, gravity/acceleration involves BALANCED inertia/INERTIAL RESISTANCE; AS E=mc2 IS F=ma; AS the rotation of WHAT IS THE MOON then NECESSARILY matches it's revolution; AS ELECTROMAGNETISM/ENERGY IS GRAVITY. Gravity IS ELECTROMAGNETISM/energy. E=mc2 IS F=ma. THE MOON is thus a frozen/constant or "dead"/unchanging form in perpetual motion as necessitated by the Earth/Sun BALANCE that fundamentally governs and generally shapes it IN ACCORDANCE WITH the UNIVERSAL fact that E=mc2 IS F=ma. GREAT. I have mathematically explained or proven why there is NO RESISTANCE regarding WHAT IS THE MOON in BALANCED RELATION to the Sun AND the Earth, AS E=mc2 IS F=ma; as this CLEARLY then explains the perpetual motion of WHAT IS THE MOON. Alas, gravity AND ELECTROMAGNETISM/energy are linked AND BALANCED opposites; AS E=mc2 IS F=ma; AS ELECTROMAGNETISM/ENERGY IS GRAVITY. "Mass"/ENERGY is gravity. ELECTROMAGNETISM/energy is gravity. I have explained why objects fall at the SAME RATE (neglecting air resistance, of course), as ELECTROMAGNETISM/energy is gravity. Gravity IS ELECTROMAGNETISM/energy. It ALL CLEARLY makes perfect sense. Beautiful. E=mc2 IS F=ma. THE EARTH/ground is E=mc2 AND F=ma IN BALANCE, as this CLEARLY then also explains why we do not feel the rotation of WHAT IS THE EARTH. Alas, what is THE MOON is a linked AND BALANCED opposite in relation to the Earth AND what is the Sun; AS E=mc2 IS F=ma; AS ELECTROMAGNETISM/energy is gravity. Accordingly, the Moon remains the same (or basically constant) insofar as it's rotation necessarily matches it's revolution. Indeed, the SPACE that the Moon occupies is understood as being FULLY formed/manifest. The motion of the Moon (thus defined) FIXES, defines, or encompasses RELATIONAL motion.
The relationally VARIABLE EXPERIENCE of what is THE EARTH/ground is thus directly comparable to what is then understood as the INVARIANT form of what is the Moon (ON BALANCE), AS E=MC2 IS F=MA. GREAT !!!

Frank DiMeglio is RECOGNIZED as having mathematically unified physics. Hossenfelder is knowingly and deceitfully lying about physics.
WHY ELECTROMAGNETISM/ENERGY IS GRAVITY:
Gravity/acceleration involves balanced inertia/inertial resistance, as ELECTROMAGNETISM/energy is gravity. This is consistent WITH F=ma AND E=mc2, as gravity IS ELECTROMAGNETISM/energy. So, inertia/inertial resistance is proportional to (or balanced with/as) gravitational force/energy; as this balances AND unifies ELECTROMAGNETISM/energy AND gravity; as this balances gravity AND inertia. In other words, GRAVITATIONAL force/energy is proportional to (or balanced with/as) inertia/inertial resistance; as ELECTROMAGNETISM/energy IS gravity. Accordingly, gravity/acceleration involves balanced inertia/inertial resistance; as gravity IS ELECTROMAGNETISM/energy. It is proven. Energy has/involves gravity, AND energy has/involves inertia/inertial resistance. "Mass"/energy involves balanced inertia/inertial resistance consistent with/as what is balanced ELECTROMAGNETIC/GRAVITATIONAL force/energy, as ELECTROMAGNETISM/ENERGY IS GRAVITY.

Hello Sabine, I got your book Lost in Math as a Christmas present, so far I'm really enjoying the read and your writing style (in particular your humor).
I'd like to say thank you for inspiring me (someone who's still in school, but plans to go into physics) and many others.
Good to see you here!
@@SabineHossenfelder Excellent book! Probably the best science book I read since "A Brief history of Time". Enjoy
Is it an English publication?
Love your handle, mate. Classic.
Best wishes with your learning.
Sabine should write college courses. Humour is a sorely underrepresented area of education!
So did I!! And as a 60+ person, who has read many layman physics books, so far I'm loving hearing my inner voice sounding like "Sabine-Einstein."
"the physics is simple but the biology isn't"
True indeed! Messy as hell but promissing!
I have been exposed to radiation in high doses, additionally my x wife also. My x wife developed Graves disease as mentioned by Sabina here, and she did take the radioactive Iodine pill and it worked flawlessly. On a side note, they typically give you the option of actual surgery to remove portions of your thyroid gland however this surgery is very risky and has potential of significant morbidity. I had a very large pituitary tumor that surgery was unsuccessful at removing and so I had radiation treatment to render it inert. The technical term for the treatment I received was fractionated stereotactic radiotherapy treatments over 30 days once per day. I will say, if you are exposed to beams of proton radiation in your head you can feel it hitting you and it manifests as a bright blue light, sorta like a cross between the blue of lightning and a tanning bed. When I received a blast of this radiation I could feel it hitting my forehead or the top of my head or back like someone pointing a garden hose at me with blue light pouring out. The oncologist explained to me that an outside observer does not see the light , it's the radiation hitting my optic nerves and "inducing" the perception of bright blue light. the treatment I received was from a system called Novalis Tx and it saved my life.
Thank you!
In a brief moment of time your eyes were augmented. You're a pretty lucky man.
I'm exposed to high radiation right now. I'm standing in front of my infrared heater.
Thanks for sharing your story. I'm glad your wife and you are well. Best wishes!
while I was being treated with radiation I was given high doses of steroids, Prednisone, to combat the swelling of my brain. after it was completed most of my hair grew back except for a round spot sorta in top back but not in the normal spot men lose their hair at. for about 2 years after I experienced face blindness, loss of long term memory, adrenal insufficiency crisis and behavioral changes. My pituitary is basically a empty husk laying at the bottom of the sella turcica so I must take all the hormones normally induced by the gland, thyroid, cortisone, testosterone. I struggle with depression and pain as replacement of cortical steroids orally doesn't come close to how the body manages it via the HPA axis. The years of having a bi producing tumor over 3 cm caused me to have metabolic syndrome and type 2 diabetes, but surprisingly my eyesight is intact with no noticeable damage to my optic nerves.
This is the kind of vid that really shows just what a valuable resource RUclips can actually be.
Sabine, thank you for your nice explanation. I am a physicist, and what immediately caught my attention (I almost spilled my coffee) is your definition of radiation as "energy transfer by waves or particles". Actually, I never bored to define for myself what "radiation" exactly means, because every time it is clear from the context what I am dealing with (sometimes to remove the ambiguity we use word "radiation" in combination with other words like "electromagnetic radiation", "acoustic radiation"). But, if we decide to define radiation, I would exclude "particle" from this definition. Otherwise, you cannot distinguish between radiation and convection, or you have to admit, that electric current is radiation (because in both cases energy is transferred by particles). We do not want to climb this rabbit hole.
Then you'd have to exclude neutrons and alpha and beta particles also, which most certainly should be included.
I was surprised by this definition too. Tbh I had always assumed radiation was a shorthand for electromagnetic radiation in most context. And occasionally it also included fast moving individual particles like cosmic rays, alpha particles, etc. Then I googled the definition and it doesn't seem very consistent 😂
Thank you Sabine and happy holidays 🥰
Happy Holidays to you too!
This is quickly becoming my favourite science channel.
Sabine, thank you very much. You’re a brilliant communicator and it’s always a pleasure to learn from you.
I appreciate your deep knowledge and your critical thinking.
I discovered your chanel just now and I'm in love with it, I'm already two days straight watching many videos I always had curiosity to know about and always thought "why no one explain this?" And here you are, explaining so much, so scientifically, your uses of logic are amazing, thank you so much for your videos
13:20 *Radiation hormesis* sounds like a variant of "what doesn't break you makes you stronger." That idea works in many other cases-vaccines, physical exercise, tanning-up to a point. But it's too easy to get over-motivated, push boundaries, and end up with paralytic poliomyelitis, torn muscles, and carcinoma.
Playing around with radiation is particularly dangerous. Talking about (nuclear) radiation or nuclear energy always causes a strong reaction in me. Images of Marie Curie, Eben Byers, Richard Feynman, Litvinenko, Chernobyl, Fukushima, Hanford Site etc. flash in front of my eyes forcefully and involuntarily. You can be sure I'm going to remain very, very skeptical of radiation hormesis-I may never trust it in my lifetime.
Always good to cover the basics; absorbed a few more interesting facts. Thanks Sabine!...

@@doomedtolinger2213 nah, no damages here. I wasn't actually drinking my coffee near my phone at the time of seeing it, so no harm, no foul.
But I _did_ happily give you a like for it!
Excellent video.
You can mention in future videos few supporting experiments for the theories.
For example :"This is how to measure Total Ionizing Dose....
This is how to measure heavy ions impact....
This is how NOT to detect Higgs bosons"
;)
Yes, that would make the ideas more concrete.
I am relatively new to your channel and I want to say how much I appreciate the videos you make. I love science but I am not well educated in it. I appreciate your genius of being able to simplify subjects - but not TOO simple. Really, your work is just perfect for someone like me. Thanks
You can still educate yourself in it. It's never too late for anything.
Sabine you have no idea of what a fan I have become of you. Thank you for explaining science in a great way.
Happy you find my videos useful!
Hi Sabine!!! I want to express two things: firstly I really appreciate your teachings in Physics. I’ve been involved because of my studies with a certain amount of physics in the past and I eagerly follow some scientists to learn a little more about our Universe. Secondly I saw your video about Speaking English and I can say that I really like to hear you speaking!!! It’s a neutral accent and I, being for Argentina and having Spanish as my mother tongue, really appreciate each and every word you speak. And believe me, I can cope with English without any problem but I’m far away from an educated English speaking person, but you DON’T have a single mistake! It’s really a pleasure watch your videos just for knowledge of both, science and English. Thank you! I really admire you!!!! Kisses from Argentina!!!
Agree with the Great Courses recommendation. I have gotten several and the one that impressed me most was "Thermodynamics: Four Laws That Move the Universe". (There are probably many others worth viewing.)
7:36 "...which is not healthy" is still in the closed captioning Sabine.
7:38 the sounds cuts in the last part of the sentece, what did i miss? ..."also cause"...
I so like how you present and the down to earth way you are able to present all these subjects, i so wished you where my teacher 25 years ago.
"...may also produce ozone."
You answer ordinary ppls everyday worries and thoughts based on science!
3:47 « or maybe they don’t exist in the first place » 🤣🤣🤣
That was extremely informative and easy to understand. Thank you Sabine.
Very interesting as usual. Were there any studies on pilots, astronauts or communities living at high altitudes in relation to longer term exposure to higher levels of ionizing radiation?
The fact that this video has 0 dislikes (at my time of watching) shows how good of a work you are doing!!! Keep going
Does not matter if a video gets likes or dislikes, the algorithm treat them both as a social engagement and will promote the video based on the absolute engagement (up+down). So if someone really really hated a video they should not comment and not down vote :-) knowing this makes me smile every time I see people down vote a great video.
Thank you, beautiful lady, I did learn something today!
As always, great stuff Sabine! I would like to add however that radiation in the microwave spectrum may not be ionizing, but they can affect protein conformation and thus alter enzymatic activity, receptors, and therefore metabolism. This is a potential issue for 5G systems.
True. Which should be obvious to anyone that uses buck of saline as a model while bullshitting the public.
Good job of explaining radiation. You are correct about the complexity of radiation safety. I was the radiation safety officer for three companies. While you can predict the effects of an acute high level exposure long term effects of an exposure for an individual is unpredictable, yet statistically significant for a group of individuals receiving a similar dose. Probably the worst thing for an individual is a long term low level dose from an ingested substance. Smoking is one such ingestion mechanism. Radon in the smoke is deposited in the lungs as a radioactive isotope of lead. Body tissues are exposed continuously to low level radiation, many individuals then develop lung cancer. And that is an over simplification. I have seen the whole body radiation counts for smokers, their lungs "glow" bright!!
I like that new animations and effects! The overall quality of your videos gets better and better every time! Can't wait for more people to be interested in your content :)
Danke Frau Professor, wieder was gelernt :)
Two people in my life made me love science...Nancy Comer (9th grade Physical Science teacher) and Sabine (just wow, she is amazing). Without question, I would listen to her discuss cookie recipes or the table of contents from boring books.
Since we're on the topic of radiation - can you recommend any sources about whether using vintage radioactive camera lenses like the Super Takumar 50mm f1.4 would cause damage in the long term? I'd assume not since the camera body would probably block a lot of the radiation emitting from the rear of the lens, but we don't have any sources from actual scientists online - just people with cheap amazon bought pocket Geiger counters.
It’s a delight to listen to Dr. Hossenfelder. The density and clarity of her expression is unique on RUclips. Such a beautiful way to learn about science and the martial art of argumentation at the same time.
7:38 The air purifier companies edited the one out
The simplicity of how this subject is taught is incredible. It make a person want to learn more about radiation and its affects...
Also, its effects.
It wasn't until my classes in modern physics, electromagnetism, etc. that a lot of physical concepts became clear, or at least somewhat tolerable.
Thanks Sabine for all the refreshers!
When Americans, at least, express concern over "radiation", they invariably mean radioactivity.
i think they just think chernobyl
When they hear the word radiation, they hear radioactivity...and then panic.😅
If you express radiating ripples on the surface of water as radiation, they'll panic.
@@kombinatsiya6000 Or Three Mile Island, although it never reached the level of Chernobyl.
The N word (nuclear) has the same effect. They think of bombs destruction and death, which in turn "justify" to reject nuclear energy. For the most part their education truly failed them.
And we needs to distinguish between internal and external exposure to radioactive isotopes and their ionising radiation.
07:02 There is little slip in the graph. Ionized molecule can also have extra electron (in case of radiolysis). So, "lack electrons" is not always true.
A video about electromagnetic radiation from appliances phones, and power lines would be very helpful.
She has already done a video about cell phones and 5G. Basically, the answer is don't worry about it. So long as you don't climb any fences that are designed to keep you away from things, it isn't a hazard.
Sound is often referred to as radiation by sound engineers. They talk about how speaker cabinets ‘radiate’ the sound. In multiple speaker arrangements the polar patterns resemble those of the double slit experiment.
This is one of your better and more useful videos for average people.
Please do a video on voltage-gated calcium channels in the context of cell phone radiation and its biological effect.
Thanks a lot, Ms. Sabine. I was wondering that If it is possible for you to make a video about Geiger counters and measurement quantities such as sievert and rem.
Thanks for the suggestion, I will note that down! Have to see if I can find my Geiger counter...
Like
@@SabineHossenfelder I would suggest getting an RF meter that can measure 4g/5g. Place it up to the glass of a running kitchen microwave and then place it against your cell phone and make a call. I am getting about the same reading on a 4g phone and a 1200 watt running microwave. I think you will find much more to be worried about using an RF meter than using a Geiger counter.
@@melgibson6331 Geiger counters measure ionising radiation, mainly beta particles and to a lesser degree alpha particles and gamma rays (which are high-energy EM waves). The "radiation" used in radio and so-called "microwaves", including the transmissions from 4G and 5G networks are below the infra-red band and only cause heating, not ionisation. A GM counter will register nothing from these. On the other hand, an X-ray will set a GM counter screaming! Sound is another form of "radiation" which simply means some form of energy spreading outwards. The engineers who work with RF circuits and high-power microwave devices like radar antennae have no health problems whatsoever, the greatest risk being a burn.
@@SabineHossenfelder Start with ionisation chambers, they are much simpler devices and measre directly the ionising effect of radiation. The downside is that the output can be as low as a few thousand electrons per second, but this is not very difficult to measure. GM tubes are great but their operation is quite complex.
Wait! Is Saturday already? Where the week went?
Oh, well...Thank you, Dr. Hossenfelder!
Regarding radiation hormesis, I know lots of radiation scientists, and as far as I'm aware, nobody exposes himself to radiation on purpose in order to increase his resistance to it. The idea makes sense in principle, and I remember I've seen some evidence in in-vitro experiments, but most of the evidence is cirmustantial, based on statistics of the health of people who are professionally exposed to radiation. The issue is that correlation doesn't imply causality. For instance, they may be healthier simply because they are subject to strict periodic medical check-ups, and this may help to detect illness at an early stage and treat them. It may also help to remove from the group those who are unhealthy.
Very interesting and explained well. My question is in knowing that our magnetic fields weakening and not shielding us from harmful cosmic rays, is this concerning?
No.
Because the Earth magnetic field don't stop the cosmic rays.
The atoms in the atmosphere does, crashing with them and producing particle showers(look the video again, Sabine mentions this)
Now, the solar wind with his charged plasma is another issue, of course...
@@eljcd Thanks for this John.
One thing that came through loud and clear (very clear) on this and another related video on 5G is the two mechanisms of energy transfer from EM waves/particles - quantum energy levels that can damage specific molecular structures because they are 'matched' to the energy levels of EM quanta and heating as a function of power levels. A question that still puzzles me though is the effect of pulsed systems with very high peak pulse power and very low average power. For instance, a marine radar magnetron can have a peak power of 20kW and an average power of 20W. The 20W will obviously heat tissue close up but will the high peak power have any effect? I don't know! Anyone else?
For radio waves what matters is the total energy deposited into tissues which results in heat, and which tissues absorb them. The total energy is related to the average power. Pulsed sources can have very high peak power but much lower average power. So long as the peak duration is short enough that the tissues don't have time to heat up significantly during one pulse, then all that matters is the average power. Radar transmitters use highly directional antennas that concentrate that average power into a very narrow beam. You wouldn't notice 20W of energy deposited over your entire body. But 20W deposited into a small area would cook the tissues.
Think of it like a candle flame. You can't feel anything if you're standing next to a lit candle as its radiated energy is being spread over your entire body. But stick your hand into the flame so the energy is concentrated into a small spot, and you'll certainly notice it (and be cooked by it). A single candle flame is coincidentally also about a 20W average emitter.
So for the marine radar, if you're far enough away that the diverging beam covers an area bigger than your whole body it isn't a big deal. But if you're standing right in front of the antenna so that the beam is only hitting a small area, that's a problem.
Your comment on dark matter particles was amazing hahaha
Nice video, it would have been nice for you to have touched on neutron radiation though.
Sabine, you have done a great service in educating the public on topics in physics and astronomy, in which you are an expert. If you take the time to educate yourself, you may also be a valuable resource on epidemiology. But there are unexpected biological effects and a great deal of commercial influence over the science, so you have to read carefully to see the big picture.
Radiation hormesis is real, though it has been made "controversial" by politics.
And the most important biological effect of cell phone radiation is throuh voltage-gated calcium channels. Please read about this so you can serve the great number of us who have put our faith in you.
I have measured gravity, and performed radiography, on the Arctic Coastal Plain, of Alaska. We used Cobalt, for our source. When I was hired to do a gravity profile, I did not know, gravity was measured. I just told the interviewer I had done it before. I read the manual on the flight to Barrow, and worked there three years. I never really understood what gravity is, but completed my tasks. We used a helicopter in Summer and a track vehicle in Winter. I worked alone in Winter. Lovely, Northern Lights, which are charged particles as well, interactions are in the atmosphere. Lovely, to view, in the Arctic mirrored in the Antarctic.
So you measured the local acceleration due to gravity in various locations?
Here in the USA we hear about anti-oxidants. Are oxidants really that harmful or is it marketing hype?
Antioxidants (like are found in fruit) are chemicals which help protect your DNA from oxidization and oxidants (like charcoal) increase the rate of oxidization.
Oxidization damages the DNA and can increase the risk of cancer in healthy people. However studies have also found that antioxidants can also unfortunately protect DNA which is already cancerous.
Essentially they are good if you don't have cancer, but aren't so good if you do.
They're not ionizing radiation levels of harmful but you shouldn't be eating burnt meat all the time.
@@filiecs3 So, not breathing oxigen will be good for your health?
@@eljcd No, you very much need to breathe Oxygen. I am talking about DNA oxidization: en.wikipedia.org/wiki/DNA_oxidation
Another definition of 'Oxidization' is "To increase the positive charge or valence of (an element) by removing electrons", which is what DNA Oxidization is: www.thefreedictionary.com/oxidization
Now that we are on a "debunking" round of video's, could you please do one on Nuclear Reactors and the misconceptions about their safety?
Nuclear is a word that scares people, eventhough it's safe :D
Nobody has a suitable waste site. Japan is shipping it to Texas. Idaho and Nevada don't want it anymore and are shipping it to New Mexico. Round it goes. The EU has no site.
@@davidb2206 The EU will have a permanent waste storage facility, in fact the worlds first of its kind in Finland pretty soon, main construction is already done
@@teaser6089 Well, congrats to them, but let's see how it goes and how much it can handle. All of EU? Nuke waste is still a problem, worldwide. Americans don't want it in their backyard, either, even at the existing sites (none of which are fully approved right now, as I recall, for the highest tier, except the New Mexico).
Lovely video but you failed to mention two common things people should hear.
1. Some exposure to sunlight is desirable. Sunlight causes the body to generate Vitamin D. Many people in northern latitudes are deficient in vitamin D, especially during the winter.
2. Photons with a wavelength greater than 100nm (UV-C) are non-ionizing. They don't have the energy to damage molecules directly. That means optical light, infrared light, microwaves, cell phone signals, and other radio emissions are non-ionizing. Any photon source can cause harm in large enough quantities, but the mainly through heating. A microwave is a heat lamp that emits lower power photons on a longer wavelength that we cannot see. Cell phones emit lower power photons than a keychain LED flashlight.
I really enjoy your videos. After recently discovering this channel I have been watching your older content almost daily.
"...or maybe they don't exist in the first place." Thank you. Cracked me up.
Isn't the 'Power' of radiation equal to the 'Intensity' which is relative to the 'Amplitude' of the wave as well? Or what do I miss?
I really like videos like this that carefully define terms and connect them to the salient points necessary to understand a topic. Great job! I am currently radiating happiness. Thanks
Brilliantly explained! Thank you
Really, really interesting!
Thanks a lot, Sabine! 😊
Happy new year! And stay safe there with your family! 🖖😊
Thank you.
Recently I learned that photons are particles which carry X-ray - gamma radiation. So is it as well photon which is produced in magnetron in microwave oven? Is it photon which is used to broadcast radio?
I noticed you cut out what you were going to say about some air purifiers creating ozone. I really wanted to hear about that 😔 because I was curious how healthy my "ionizing" air filter is.
Good. Thank you for this vedeo
Estimating radiation exposure can be very difficult to do in a meaningful way. For example, suppose you have a block of radium in your living room, in a sealed capsule. Most radium atoms, from the most common sources, are alpha emitters, so almost any container would protect you from any direct radiation. The process produces radon, but this is an inert gas, and with good ventilation would not have little exposure to that, either. OTOH if you ingest radium, almost every alpha particle from decays will deposit its full energy in your body, so that could be very dangerous. If it's in your bones, it will probably stay there, which is even worse. So the environmental circumstances make huge differences in risk.
The page Nexus of Physics has now given the following two writings the thumbs up on their page. ALSO consider this: E=mc2 is DIRECTLY and fundamentally derived from F=ma, AS E=mc2 IS F=ma; AS time DILATION proves that electromagnetism/ENERGY IS GRAVITY.
THE UNIVERSAL AND MATHEMATICAL PROOF THAT ELECTROMAGNETISM/ENERGY IS GRAVITY:
Energy has/involves GRAVITY, AND ENERGY has/involves inertia/INERTIAL RESISTANCE. "Mass"/ENERGY IS GRAVITY. ELECTROMAGNETISM/ENERGY IS GRAVITY. E=mc2 is DIRECTLY and fundamentally derived from F=ma. GRAVITATIONAL force/ENERGY IS proportional to (or BALANCED with/as) inertia/INERTIAL RESISTANCE, AS ELECTROMAGNETISM/ENERGY IS GRAVITY. SO, gravity/acceleration involves BALANCED inertia/INERTIAL RESISTANCE consistent with/as what is BALANCED electromagnetic/gravitational force/ENERGY; AS ELECTROMAGNETISM/ENERGY IS GRAVITY. "Mass"/ENERGY involves BALANCED inertia/INERTIAL RESISTANCE consistent with/as what is BALANCED electromagnetic/gravitational force/ENERGY, AS ELECTROMAGNETISM/ENERGY IS GRAVITY. Gravity AND ELECTROMAGNETISM/ENERGY are linked AND BALANCED opposites, AS ELECTROMAGNETISM/ENERGY IS GRAVITY. THE SUN AND THE EARTH are described and represented by BOTH F=ma AND E=mc2. F=ma AND E=mc2 PROVE that ELECTROMAGNETISM/ENERGY IS GRAVITY, AS ALL of SPACE is NECESSARILY electromagnetic/gravitational (IN BALANCE). Objects fall at the same rate (neglecting air resistance, of course), AS the SPEED OF LIGHT is RELATIVELY CONSTANT AS WELL. ELECTROMAGNETISM/ENERGY IS GRAVITY. Gravity IS ELECTROMAGNETISM/ENERGY. In fact, the rotation of THE MOON MATCHES it's revolution; AS gravity/acceleration involves BALANCED inertia/INERTIAL RESISTANCE; AS ELECTROMAGNETISM/ENERGY IS GRAVITY. So, THE PLANETS (INCLUDING WHAT IS THE EARTH) are not "falling" in what is "curved SPACE" in RELATION to what is THE SUN. This is nonsense. E=mc2 is DIRECTLY AND FUNDAMENTALLY DERIVED FROM F=ma. This truly explains PERPETUAL MOTION. Very importantly, outer "space" involves full inertia; AND it is fully invisible AND black. The stars AND PLANETS are POINTS in the night sky. A PHOTON may be placed the center of THE SUN (as A POINT, of course), as the reduction of SPACE is offset by (or BALANCED with) the SPEED OF LIGHT; AS ELECTROMAGNETISM/ENERGY IS GRAVITY.

EINSTEIN NEVER UNDERSTOOD PHILOSOPHY, MATHEMATICS, AND PHYSICS, AS HE HAS BEEN TOTALLY OUTSMARTED BY SIR FRANK MARTIN DIMEGLIO:
The balance of being AND EXPERIENCE is ESSENTIAL. BALANCE AND completeness go hand in hand.
THE SELF represents, FORMS, and experiences a COMPREHENSIVE approximation of experience in general by combining conscious and unconscious experience. MOREOVER, the ability of THOUGHT to DESCRIBE OR RECONFIGURE sensory experience is ULTIMATELY dependent upon the extent to which THOUGHT IS SIMILAR TO sensory experience. THOUGHTS ARE INVISIBLE.
Dream experience is/involves true/real QUANTUM GRAVITY, AS ELECTROMAGNETISM/ENERGY IS GRAVITY. MOST IMPORTANTLY, in dreams, BODILY/VISUAL EXPERIENCE is invisible AND VISIBLE IN BALANCE. IMPORTANTLY, dream experience is possible/potential AND actual IN BALANCE. THE EYE is ALSO the body. Dreams improve upon memory AND UNDERSTANDING. Indeed, there is no outsmarting the GENIUS of dreams.
OVERLAY what is THE EYE in BALANCED RELATION to/with what is THE EARTH. NOW, get a good LOOK at what is the translucent, SEMI-SPHERICAL, QUANTUM GRAVITATIONAL, AND BLUE sky. Excellent. The DOME of a person's EYE is ALSO VISIBLE. THE EARTH IS also BLUE (as water).
F=ma AND E=mc2 PROVE that, why, and how ELECTROMAGNETISM/ENERGY IS GRAVITY. This NECESSARILY represents, INVOLVES, and describes what is possible/potential AND actual IN BALANCE. SO, it is NECESSARILY a matter of precisely how these equations are understood in a BALANCED, EXTENSIVE, AND INTEGRATED fashion in RELATION to/with WHAT IS THOUGHT. The INTEGRATED EXTENSIVENESS of THOUGHT (AND description) is improved in the truly superior mind. E=mc2 is DIRECTLY and fundamentally derived from F=ma.
Very importantly, outer "space" involves full inertia; AND it is fully invisible AND black.
The stars AND PLANETS are POINTS in the night sky. A PHOTON may be placed at the center of THE SUN (as A POINT, of course), as the reduction of SPACE is offset by (or BALANCED with) the SPEED OF LIGHT; AS ELECTROMAGNETISM/ENERGY IS GRAVITY. Get a good LOOK at what is THE EYE. POINTS are points. Gravity IS ELECTROMAGNETISM/ENERGY. ELECTROMAGNETISM/ENERGY IS GRAVITY. GRAVITATIONAL force/ENERGY IS proportional to (or BALANCED with/as) inertia/INERTIAL RESISTANCE, AS ELECTROMAGNETISM/ENERGY IS GRAVITY. "Mass"/ENERGY involves BALANCED inertia/INERTIAL RESISTANCE consistent with/as what is BALANCED electromagnetic/gravitational force/ENERGY, AS ELECTROMAGNETISM/ENERGY IS GRAVITY. Gravity/acceleration involves BALANCED inertia/INERTIAL RESISTANCE, AS ELECTROMAGNETISM/ENERGY IS GRAVITY. "Mass"/ENERGY IS GRAVITY. ELECTROMAGNETISM/ENERGY IS GRAVITY. Energy has/involves GRAVITY, AND ENERGY has/involves inertia/INERTIAL RESISTANCE. F=ma AND E=mc2 PROVE that ELECTROMAGNETISM/ENERGY IS GRAVITY, AS ALL of SPACE is NECESSARILY electromagnetic/gravitational IN BALANCE; AS ELECTROMAGNETISM/ENERGY IS GRAVITY. GREAT.
The stars AND PLANETS are POINTS in the night sky. OPEN your EYES. NOW, LOOK at what is the FLAT, SETTING, AND ORANGE SUN (with the SPACE around it THEN going invisible AND VISIBLE IN BALANCE). This ORANGE SUN manifests or forms at what is EYE LEVEL/BODY HEIGHT as well. This ORANGE SUN is manifest ON BALANCE as what is NECESSARILY the BODILY/VISUAL EXPERIENCE of THE EARTH/LAVA. The viscosity of LAVA IS BETWEEN what is manifest as WATER AND THE EARTH/GROUND. ALL of SPACE is NECESSARILY electromagnetic/gravitational IN BALANCE, AS ELECTROMAGNETISM/ENERGY IS GRAVITY. F=ma AND E=mc2 do provide absolute, BALANCED, THEORETICAL, and CLEAR proof that ELECTROMAGNETISM/ENERGY IS GRAVITY.
Gravity/acceleration involves BALANCED inertia/INERTIAL RESISTANCE, AS ELECTROMAGNETISM/ENERGY IS GRAVITY. THEREFORE, the rotation of THE MOON MATCHES it's revolution. MOREOVER, a given PLANET (INCLUDING WHAT IS THE EARTH) sweeps out equal areas in equal times; AND this is THEN consistent with/as what is F=ma, E=mc2, AND what is PERPETUAL MOTION; AS ELECTROMAGNETISM/ENERGY IS GRAVITY. It ALL makes perfect sense. BALANCE AND completeness go hand in hand.
THE PLANETS (INCLUDING WHAT IS THE EARTH) are NOT "falling" in what is "curved SPACE". In fact, this is nonsense. It is PROVEN.

I remember reading a case study from the 70s that said low frequency power lines are harmful to health and can cause depression and dullness, esp in children. Powerlines that are overhead and buried (not too deep) underground.
Good point! That same studied concluded that when cities are developing, the areas where power lines converge into transformer stations are often less desirable areas for luxury housing. So, what happens is that low-price housing or council estates are built near these areas of powerlines and transformer stations and it appears that the people living in those houses are on lower incomes and perhaps do not spend as much on education and health care. A similar case exists for land prone to flooding - it will have a lower value and attracts low-priced housing or caravan parks, so when a flood occurs it is the same demographic group that is affected. It is the politicians and developers who deserve the blame for this problem, not the power lines!
The cattle underneath the high voltage lines have significantly higher miscarriages, but nobody wants to talk about this.
Thank you, Sabine! Radiation hormesis is exactly the term I needed to explain the difference between a younger and older stellar environment. I believe that as our Sun and Earth age there will be less radiation hormesis. I predict there will be less of a variety of living beings but the ones currently inhabiting the planet will become more stable and be able to have longer life spans. Radiation hormesis is a type of stimulation the can produce mutation but is also degrading to life. Good for a young solar system but is less ideal for a mature solar planet.
Sabine madam is the best explainer
Love the "controversy" indicator and the explanation that went with it.
love the intro.
Yet another well done science video, Sabine! Thank you for what you do!
imagine we could see all of the EM waves that are emitted all around us. What a bright world that would be. I think that would definitely make radio a very interesting thing. AM modulated radio would be like a super bright beacon that dims and brightens regularly and FM would look like a super bright light rapidly and regularly changing colors. Man that would be cool.
It would be beneficial to explain the difference between radioactive contamination and nuclear radiation. Journalists tend to equate the two whenever they write about nuclear power accidents.
if neutrinos or dark matter only interacts rarely... what happens when they indeed interact with our body?
I like your matter of fact demeanor.
Neutrinos: going through Peter Parker by billions every second.

I guess that's one way to get rid of "foot funk", lol.
According to Wikipedia, roughly 90% of cosmic rays are protons, 9% are alpha particles, and only 1% are electrons. Is the earth and its atmosphere becoming continuously more positively charged? If not, what counter-balances all the positively charged cosmic rays?

Biochemist here, this is all accurate. Sabine, I particularly appreciated your methodical approach to this subject: clear and concise, with just enough perspective and nuance. Good work!
Excellent topic snd really well narrated. Well done.
How does this apply to WiFi and microwave emissions? Cell phones?
You should do a video on the OMG particle.
You brought up that some cosmic rays still get through the O3 layer. Some places have little O3 above them, ozone hole affected regions. Do you would think people would live longer if society moved underground?
the way waves are always shown really bother me, like I assume the single wave shown is not the only one. do they radiate in all directions available? are all exiting waves in the same orientation as the example slice?
