Here's a bit more on the temperature question (www.slate.com/articles/news_and_politics/explainer/2012/07/my_body_temperature_is_98_6_degrees_so_why_is_98_6_degree_air_unbearable.html) In short, the hotter it is outside, the less efficiently we expel heat from our bodies, causing body temperatures to rise. Thanks for watching; have a great weekend! -- KH
Can you talk about Deadpools Continuity stone?
Because Science woah, woah woah you are assuming a straight edge blade geometry, what if the blade is two concave surfaces meeting at a sharp point? Then the bullet pieces trajectories should be deflected further out than a simple straight surface because the equal and opposite reaction is more perpendicular than with the 44 degree wedge you mentioned, granted you would need some material that has greater strength.

Its an error in youtube handling your () with the link...there is a ) at the end of the link
Yeah. You kind of butchered that. 😂
I really love your comments on science communicators, your job isn't to know 100% of every theory of every scientist in the past 200 years. Your job is to make a powerful enough statement to intrigue people and make them interested in basic and sometimes complex subjects. And, make them curious enough to go out and teach themselves or to ask more complicated questions to more educated individuals to really learn what science is, so that they can really understand a full concept. Think of it this way, many, many middle and high school science teachers do not have a doctorate they are bachelor and master degree level educators. There is nothing wrong with that, two of my favorite teachers were my 7th grade science teacher and my 10th grade Biology teacher. Both were dedicated scientists who found a way to appeal to my particular sense of humor. I was probably one of the only kids in their classes that found them particularly funny. But, they put into me a very powerful message that science was important, and they gave me a love for something so complex that it is impossible to study it in it's initiatory and I soak in as much as I can, or at least as much as I can understand. Everything from complicated particle physics to basic human interaction I love studying it all. Kyle people like you, what you do everyday on this channel keep that passion alive in me. It causes me to think about and discuss with my friends things that most people never imagine, it makes me look up the mundane things like how caffeine and nicotine react with our bodies and how bad they actually are for you. Never, ever let anyone tell you that you are not important to the science community or that you don't make a strong enough contribution because your lack of a certain or high enough degree I say that you are one of the most important parts the person who draws people in and empowers them to learn more and become the educators or the advanced minds of the next generation. Thank you for what you do, never turn back from this path, no matter what anyone says you were made to make people ask questions, which is the best way to help people learn.
I've met lots of people with tons of doctorates who have absolutely zero communications skills. Doesn't mean they were not good at science, they just had trouble communicating and transmitting their love of science to the uninitiated. Makes sense Kyle of Asgard here has a Masters in Science Communication, that's the kind of skill set you'd need in his line of work. Leave the crunching of the numbers to those scientists who are anti-social and speak in terse, cold, and analytical sentences. My favorite science teachers were the ones that came in saying "Okay, I was watching Airwolf last night and there was this crazy maneuver that the helicopter did which defies physics...we're discussing why..."
that is an essay, not a comment

Simple and early combustion engines use/d about 1% of the energy in gasoline to actually propel the vehicle. Modern automotive engines typically use 12-30% with several companies and universities currently developing engines that can use over 50% of the energy of the fuel for propulsion.
Mazda has developed a production engine that uses compression ignition of gasoline. They will begin using this technology beginning in the 2020 model year and anticipate a 20% - 30% increase in fuel economy even with a 20% increase in power output as compared to spark ignition gasoline fueled engines.
Beat me to it :D
Yea bad isn't it......😔
I believe it is physically impossible for a pure combustion engine to get more than 45% or around there energy conversion output. Mostly due to heat loss or air compression energy conversion losses.
@@trevorthieme5157 extremely difficult but not impossible. The focus is improving thermal efficiency. Unfortunately I don't know too much about how they are improving the thermal efficiency.
My two best professors in college had entered teaching before you were required to have a PhD to teach in the Californi university system. One was my Organic chemistry professor who had worked in the industry for 15 years before switching to teaching chemistry. He had a lot of real world knowledge about what chemical reactions work int he real world and what ones are very difficult to control. The other was a calculus professor with a degree in civil engineering. A great teacher who made learning fun with real world examples of vectors, fields, etc. A PhD doesn't make you a good teacher or communicator, and it doesn't even mean you have a greater understanding of a subject than someone with a BS.
Demolition Ranch did the whole carrot down a shotgun bit. I dont know if people have seen it but its...spectacular lol
R. Huffman Clearly you have seen it, so if you are people, then people have seen it. Also the people who made it have probably seen it.
Dude had a 50cal blow up in his arms, he's litterely a god and everyone should know of his exploits......👍👌👍
It's not the degree that makes you a good science communicator...
It's your depth of understanding a complex idea and ability to break it into simple understandable explanations
Never be afraid to say that's beyond my expertise...
You do a wonderful job by the way...
23:20 100Watts‽ That would mean your body was expelling 100Joules/second *(0.238902957618615calories/Joule) ≈ 23.9 calories/second,
which would mean the human body would consume 23.9 calories/second * (3600seconds/hour) * (24hours/day) ≈ 2064122 calories/day,
or 2064122 calories/day (1Calorie/1000calories) ≈ 2064 Calories/day.
You're right!
Wait... Humans consume around 2000 kilo calories? I thought it was gram calories...
Food nutrition facts would be more interesting if they had calories instead of Kcals.
As heat* theres more to it than that.
For your information
Cal = Kcal
And i was always taught it was more like 60-70W rather than 100W. (1200 to 1400 Kcal per day, just to exist, even if you sit and do nothing all day)
No wonder it gets so warm when you have a few people sitting in room together. Imagine having 10 70W lamps on in one room.
Did you just use an interrobang‽ That's awesome!
I absolutely love the explanation at the end. it actually taught me a little about myself and my love for science and telling ppl about the things I know. I'm not afraid to tell people if I can't elaborate something more or if I don't know something. love this channel and have a blast watching it
The thing I always say when people bring up having a degree is this:
"What is 2+2?"
Then, when they answer, I question whether or not I can trust them because they don't have a degree in mathematics.
You don't need a degree to talk about things that already have supporting evidence. If you don't believe the communicator, then it falls unto you to disprove what they say.
I agree, it’s called making an argument from authority. The idea that someone who is a mathematician has more authority to claim that 2+2=4 than you or I do. Obviously in some cases an argument from authority is relevant. Usually in the nuances of the discussion.
You are right, someone with a degree in mathematics does not have any better argument when it is the simple question of 2+2, but be that mathematician can begin to make better argument as the information becomes more complex
guys what the fuck are you talking about
basic bitch, stay away
But proving 2+2 is crazy hard
www.quora.com/How-can-you-prove-that-2+2-4
One of the main reasons I keep watching is because you do your best to make a difficult and complex scenario easier to grasp. I've learned a lot just from watching. So thank you! Keep up the awesome work you and your team do!
Your description about Science Communication was brilliant. This video is my absolute favorite of your work.
Kyle,
Unfortunately, temperature cannot be unbounded. When the kinetic energy exceeds the speed of light, you get a black hole. You would create a Kulgalblitz black hole.
I died at 11:07 when Kyle said "Hey... I'm sorry, people are causing a ruckus here in my void". Lol 😂😂😂😂😂
As an aspiring science communicator, I love these videos and the approach you take to communicate science in a fun way. I'm a biologist but I've learned some great basic physics from this channel already.
Keep up the great work :)
Hey Kyle as to the last bit on this episode I wanted to give u a huge thumbs up. It takes so much talent to not only present what u know in an engaging fashion but also be smart enough to know when u dont know something and brave enough to put it out there especially in nerd culture, which I am a part of and love, but also realize can be very demeaning and even cruel at times to those who aren't as smart or admit they do not know all. So good on you man keep it up and love the show!
Hey papa science man, love your videos!
On your final point of this video I thought about writing a long winded comment on how much I enjoy your videos and how great of a job I think you do, but for the sake of a condensed message I'll just say that was a fantastic point about degrees and communication. I think you nailed it and you do in fact do a great job at what you are trying to do as you put it. So keep up the good work and thank you!
This might have been the best video you've done kyle... Not about anything you've explained on the board but all the life lessons and simple explanations of things that would have been an after thought to me. I really gained some insight as to who you are where you coming from and what you try to convey to us... Ever since I started watching you videos I started to question why ii haven't pursued my passion in science...maybe one day
Correction: For safety's sake, the explosive gases do come out of the sides of a revolver, every time. The gases can do severe damage to your hand if your are not holding a revolver correctly. It depends largely on the caliber of the ammunition used, but it's a good idea not to experiment, even with less powerful ammo.
since the speed of light can not be exceeded, should not that be the limit to how hot something can be? Because molecules can not move faster than the speed of light.
Theoretically, you could assume that. However, you have to take into account how small the wave lengths can get before they would technically "cease travel". As of now, the theoretical highest temperature is what is called the Planck Temperature at 1.417x10^32 Kelvin; the hottest thing we know of in our universe is ~3.9999x10^12 Kelvin). If the wave lengths were to get any smaller than what the distance of a Planck length is, then the energy wouldn't be considered moving anymore and our theories cannot compute what happens past this point.
@Kyle Gruber You could have said what is the hottest thing known. ;-)
Pudy15236, particle collisions from the Large Hadron Collider.
To make them move faster than light speed with heat would demand Infinte energy
So mass.......bla bla black hole
it's not like it'd be anywhere near easy for something to just 'vibrate' at the speed of light, though.
Dawww, the shoutout to Derek melt my heart!
P.P. Little correction here - the average temperature of the human body (of a healthy human) is not 35 degrees Celsius, It' 36.7 to 37 Celsius.
That closing monologue is literally why I watch Kyle. I don't care what degrees he has weather he's got a PhD or not he reminds me of the joy I got every Saturday back in the day when that theme song hit
🎶Bill Nye the science guy. Bill, Bill, Bill, Bill...🎶
He communicates basic scientific principles surrounding pop culture and nerd culture icons in a entertaining and engaging way. He's this generations pirate angel the science guy
I only found this now. I thought you funny and entertaining before. And your topics are chosen and presented in a way that's immersive and engaging. But the way you explained your motivations and background here was really gold! Your humble and honest attitude is what many people in all fields lack which is why they are worse at tackling the lerner's problem for it. I found this channel 2 weeks ago and had your stuff pop up - but I subscribed just now because of what you said in here. It's obviously not all a big joke to you. I like your popculture style anyways... but this video actually explained why you focused on science being fun and entertainment rather than going in deep with the numbers and proofs. I think what you do is great and important in order to bring young minds that are out there now to question things further and find science accessible. To learn afterwards how everything is always more complicated when you look at in detail is something which never end either way... I know this was made four years ago - still, a compliment is hopefully never late. So: great channel and awesome work, man.
Big cheers!
Good job with myth busters references, keep em coming. They are some of my favorite scientists/experimenters.
They should change it from iron man to STEM man
Steam, not stem.
Science
Technology
Engineering
Arts
Math.
Hagen Von I don't know where you see that... but I've never seen arts included in the list...
The arts art not ;) worthy of recognition in the nerd-iverse. Seriously tho, personally I disagree with the inclusion of arts in Stem, plus Steam is already best company PRAISE GABEN.
mazingdaddid Kyle has even included art, in a interview with the myth busters lady, they had takes about how stem is really steam. I learned it from Kyle, and I think he is credible.
Hagen Von that's fair. I mean, those are the fields that get refunded first in schools.
They way u spoke at the end about being a good science communicator... There you have show cased your communicaton! Hats Off.!! Fell in love with the talk Kyle
This was the best live show yet.
I loved the ending answer. Good job sir.
The Aztecs and Mayans had a type of sword-type weapon called a macuohuitl that consisted of a flattened paddle-type wooden club with pieces of obsidian inserted into the thin edges. Putting the obsidian into a wooden club allowed it to be used for cutting like a sword while minimizing the shattering of the obsidian as the wood provided a durable platform to support the brittle obsidian.
GREAT CLOSURE! Very enlightening, knowledgeable content and realistic understanding of science! PLEASE! Keep up the good knowledge!
Rounding it out, 275 years for the moon to move one Km, accounting for leap year. So, since 1964, the moon has moved less than 198 meters more distant. 1 cm X 365.25 is of course 365.25 cm. It’s been 54 years since the first moon landing, so 365.25 X 54 = 19, 723.5. Since that number is centimeters, we divide by one hundred. That gives us 197.235 meters. Not even 1/5th a kilometer in 54 years, so let’s knock that number up to 55, add three meters and round the distance to 200 meters per 55 years. 55 X 5 = 275(ish) years. To move ten kilometers, 2,750 years. It’s 2018 now, so since the year 0 A.D. the moon has traveled 7.37 km more distant. It’s takes 27,380(ish) years for the moon to travel only 100 km. That converts to about 62 miles. Something our cars can do in an hour easily. Our moon will have left us only after our sun has, by 45 billion years! So, the question of how far away must the moon be to stop tidal forces is completely. The moon must escape the earth completely to stop tidal forces, and must do so quickly. Why? As the moon drifts away, it both increases the axial tilt, and hours of rotation on the earths axis. The result is tide locking of the earth. But, it’s moot. A red giant sun will destroy both long before this happens. Enjoy!
P.S. Love all the shows. Keep it going.
And that's using the 1cm a day math, the actual is much much less than that. It's actually closer to 3.78cm a Year. so, the Andromeda Galaxy will collide with the Milky way far before the earths moon no longer orbits earth.
jhowe67 Yeah, in doing the research to find the movement per day, I found between 1mm and 3cm, so I went ahead and used the 1cm figure mentioned here, for simplicity. In all actuality, even by 1cm drift per day, we’re talking 50 billion years before complete tide locking of earth due to the moon. So, Andromeda and the Milky Way will have collided before then, regardless. The infinitesimal amount of drift by the moon is kind of staggering when compared to the large numbers usually associated with celestial bodies and their rate of movement.
A year is 365.24 days.
To sum up the VSauce video about the absolute highest temperature you have to look at it a different way than absolute Zero.
As things get hotter, they give off more energetic light (infrared - > Ultraviolet).
The more energetic the light, the shorter the wavelength.
So the question then becomes, what is the shortest possible length (a plank length), and what temerature would give off light with that wavelength.
And that is the uppermost limit of temperature (as we know it).
It was something ridiculous though.
1.42 x10^32 K or °C
(2.56x10^32 °F)
[142,000,000,000,000,000,000,000,000,000,000 K or °C
(256,000,000,000,000,000,000,000,000,000,000 °F)]
Apologies. There is another thing to account for, and that is red shifting. Even if the moving object couldn’t travel at C, since it is moving away it’s signal going towards the unmoving object will become more and more red shifted as velocity increases. While that wouldn’t block a signal, it would certainly interfere with it. Though, you are correct, the only principle that would block the signal from the moving object to the unmoving object would be the cosmic horizon, removing other variables that would arise from chance, and assuming the signal was very cohesive and didn’t disperse at such long distances. However, in that case, to find the answer all you need do is find the cosmic horizon we presently have, place the unmoving object on one side, and calculate the velocity increase over time that would put the moving object just outside of the far end.
I totally agree with your statements about science communicators. I was a RADAR instructor for the Navy for a few years, and I got very proficient at it, but I did not have nearly the same level of experience as another guy working there who was approaching 20 years working on that system. Third parties would often tell me that they "got it" better when I taught rather than the other guy (not a slam, we are good friends still), simply because he was less able to translate his greater knowledge into terms that our students could understand. Ph.D.s often fall into the same trap- once they become so specialized and immersed into their tiny little bubble, it becomes difficult to communicate with us "plebes." For what it is worth, this same mechanism was instrumental in the scientific revolution of the 16-17th centuries.
I think knowing a lot about science and understanding it is one thing, but to be able to communicate it to others at the same time make it interesting as to encourage others to want to learn more about it is another! AND THEY MAKE THE BEST AND MOST RESPECTABLE TEACHERS!
For the relative outside temperature thing. I think it has part to do with being in the vs shade and the wind blowing away our heat barrier. If it's sunny with no wind I can be warm even it is below 20 Celsius. We maintain heart around us and the windcan quickly ruin that and take the heat from our skin if it is strong or cold
New subscriber here. Been bingeing all your videos these few days. Great work you're doing here. 👏👏
Very rough figures, but, just for reference;
the difference between when the Moon is at apogee and perigee is about 42,592 km (405,696 km - 363,104 km). This represents about a 12% change or .0678 degrees (0.4905 degrees to 0.5583 degrees). Every orbit (28 days) the Moon does this. So there is about 2 weeks in between. This is 3,042 km per day (126 km/h) that the Moon is either moving towards us or away from us.
If i can add to the conversation about matter and energy question, Mckayla asked about i just wanna say:
1. matter can be created and destroyed. (Look up matter and anti-matter interaction)
2. i presume you are referring to the first law, also known as Law of Conservation of Energy that states, energy cannot be created or destroyed (I think you confused the energy part with matter)
3.if the matter meets his anti-matter counterpart it annihilates each other and the 2 atom's combined mass is 100% converted into energy.(no energy is created or lost, just changed from mass to energy {E=MC2} )
We can think of matter as we know as potential energy in mass form.
But thank your for your question cause it made me think allot about it.
You, Dr. Tyson and Bill Nye are among the biggest influences of me going back to school after six years to continue my science education. So, thanks man, you really are making a difference and doing great stuff
The highest temperature (Planck temperature) is 2.55x10 to the 32nd degrees Fahrenheit (1.417x10 to the 32nd degrees Kelvin.
Much respect Kyle. I love your show and your respect for your and others craft. Life long fan
Thanks, Kyle. Education's an uphill slope, and your stamina is inspirational.
The Bob Ross reference cracked me up!
And the Digimon theme!
Love what you guys are doing! I'm hooked. Thank you!
You know, you look quite a bit like thor.
Así me gusta yeah he has been told that about....99999999999999969 times
Except he wouldn't be looking like Thor, but Chris Hemsworth. :)
Así me gusta yes. He recently called himself a “Low rent Thor”. I’ll lift his hammer!!!!!
The answer to Michaela's question, especially the end, was epic
Correction - human body temp is 37.5 degrees centigrade.
You did a fairly decent explanation of hawking radiation as shown in a brief history of time. That is a really hard book to read as hawking had developed a different way of thinking due to his physical limitations, the science of discworld by Terry pratchett and others covers much of the same science but uses pratchett 's story telling to ease the reader in... I strongly recommend the series (4 science books, lots for the entire discworld series).
Regarding the question about qualifications and expertise, there is a quote attributed to Feynman and probably inspired by Niels Bohr "if you think you understand quantum mechanics, you haven't understood it"
Another great video keep up the good work.
Starts at 4:19
thank you!
Thank you. I really wish people would figure out how to trim their formerly live videos.
And maybe instead of using the "live" misnomer, they could call it "completely normal because it's now just another prerecorded video like everything else on RUclips."
Legend
Thank you
Joe Bramblett They do trim it eventually, just not right away
Been watching all your nerdiest videos. Love you.
As for an obsidian sword, the Macuahuitl a wooden club with obsidian blades, was a common weapon used by the Aztec military forces and other cultures of central Mexico. Its sides are embedded with prismatic blades traditionally made from obsidian. Very cool looking weapon, also very dangerous.
The theoretical hottest temperature is the Planck temperature. This is the temperature at which the light emitted from a source of said temperature has a wavelength of 1 Planck length. As such, the Planck temperature is defined as √[(ħc⁵)/(Gk²)] = 1.42 E32 K (3 s.f.)
Where ħ is the reduced Planck constant, c is the speed of light in a vacuum, G is the gravitational constant, and k is the Boltzmann onstant.
I just love the honesty bit at the end. I do learn a lot from Kyle and all the commenters here. 👍🏻👍🏻👍🏻
Thanks a ton Kyle! You do an amazing job communicating the science!
Like a new Bill Nye lol
10:10 You went full Dr. Manhattan there
1:07 And also obsidian isn't as stiff as steel, so it probably will "flop" (bend) over if it doesn't shatter first
22:56
What you feel is not the temperature, but the heat loss... less than you need to maintain the body temperature and you will feel warm, more than you need and you will feel cold...
I think kyber crystals with the force could hold light in place: either bouncing it really hard or changing the propieties of spacetime in the blade, like compressing a lot of space or stopping time into a cilinder, or manipulating gravitational forces inside but not outside so like a black hole, it could hold light still like in the event horizon. That would explain why you don't catch on fire or blind yourself when you turn it on. Since the force can be used to manipulate space time (force grip(gravity), electromagnetic force (shooting lightnings), time premonition, seeing things that happen in the future or the past, light years away, it's a thing that permeates everything just like spacetime...) i think it makes more sense than plasma. Like how Kylo stopped a blaster bolt but without letting the plasma dissipate the heat or form a sphere or explode, almost like it modified spacetime around the bolt so it would experience stasis, maybe in the bolt frame of reference it was still moving unaffected, but in ours it just moved in slow motion or had to travel an infinite distance before being released.
when you were answering about destroying electron. the weapon you described wouldn't work because the air between you and your enemy would be annihilated causing a release in high energy photons destroying you more then your enemy assuming you were not in a vacuum.
one way you could change the atomic structure is by causing it to do beta minus radiation causing a neutron to turn to a proton changing the atomic structure of the atom.
While not quite a sword, the macuahuitl used by the Aztecs and Maya is pretty close. It was a flat wooden club that had 6-8 obsidian blades embedded along either edge. The blades broke against any hard impacts, but it was allegedly capable of decapitating a horse. The blades were also replaceable, since they probably won't survive a fight.
Hey Kyle, referring to the lightsaber portion of the video. Star wars has different colors of the spectrum would taking two of them and striking them together cause a different portion of the spectrum to show or would it cause a small explosion as a result? BTW love watching the shows keep it up.
This is my first time watching Because Science Live and it makes me wonder if you edit out blinks or just get nervous when it's not scripted xD
Nice rolling with the tuff questions great show👍👍👍
Nathaniel Moon in Into The Badlands has an Obsidian Sword. Loveee that sword.
Kyle keep up the good work love the show
Ngl Kyle this video settled my existential dread... thank you.
In the Nuclear Navy we were told that 27% efficiency was consider extremely high.
Also it's was matter can neither be created or destroyed except in a nuclear reaction.
That except is there because they still thought of matter as separate from energy in the early days of nuclear physics. Now we understand that matter is a form of energy and when it's destroyed it changes form(into a heat for nuclear reactors).
So basically the energy can neither be created or destroyed only altered in form, is true. You have to understand that matter is just another form of energy.
There was obsidian swords tho, it was like two planks of wood that pushed together small pieces of obsidian like an edge. Was used in ancient America.
he could make obsidian throwing stars.
I think you guys should cover the question of , running a spaceship into a planet. I told my teachers about it and we talked for 1 hour. But came up with mixed answers
There's a lot of variables there. How big of a ship, how big of a planet, what kind of atmosphere, what kinds of speeds are involved... did you have a specific example in mind?
For the temperature part, a simple explanation would be that your body constantly generates heat and its much more efficient to dissipate that heat at 70 rather than 90. Making your body have to work harder to keep you from overheating, thus making it feel hot.
that took a turn for the existential xD
the thing he writing on is so clear it clearer than glass
I loved so many of the episodes you did on nerdist. I didnt know it wasnt yours and wondered why i havent seen any of it since in my youtube repeats. Nothing worse then your great skill and expertise is owned by some one else for ever just because they paid you and you agreed to work for them. Like nirvana being skull dragged through the mud dirt poor while recording labels built empires on Kurts back. Your like a better looking version of the singer from nickleback who funnily enough isnt named nickle back.
One of the things I like to think when it comes to "intelligence" is that it's simply not what one knows and understands, but merely one who is willing to learn and and understand.
PBS Digital studios has a few channels on youtube that do this same kind of breakdowns but do much much deeper into the science. If you want more of the math/physics, check out space time or infinite series.
I still enjoy shows like this though, as it never hurts to re-learn the basics, and if you can get it in a entertaining format (like is your specialty) it makes it all the easier.
This was a great episode.
I would love to see how these are filmed. What I mean is the board he is writing on and the sound recording. How do you not get echo to the mic used? What is the lighting set up?
If temperature is related to kinetic every, then there must be an upper limit. Particles can't move faster than the speed of light, so even if you could heat a particle up to the point where it was moving at/near light speed, it couldn't move any faster and thus couldn't get any hotter. Of course it would be an insanely high number, since the speed of light is so huge and most particles don't move anywhere near that speed, but it would be a theoretical upper limiter.
The classic Rpg Ultimate 7 The Black Gate had rare "glass" swords that could kill anything in one hit but shattered. Exactly as described
As a retired physicist in electro-optics and lasers R&D, I want to applaud Kyle Hill on his skill as a science communicator. I agree with his comments on science communication in the video. I also like the snarky humor he injects into his fairly accurate explanations of science in the context of pop culture.
Here are some comments on details in this video.
Kyle's explanation about conversion of mass to energy with the illustration of electron-positron annihilation was a bit convoluted. I think it would have been simpler to say that the masses of the electron and positron are converted into photons of the same energy as the total of their mass equivalent energy and kinetic energy so that total energy is conserved. In the video Kyle talked about the transformation of matter into energy, but never explicitly stated that the resulting energy is in the form of photons.
Kyle's previous explanation of a light saber as a magnetically confined plasma is a good one, but is not consistent with George Lucas' original concept of a "laser sword" as Kyle has acknowledged.
I propose that Kyle's concept of a magnetically confined plasma can be combined with a laser to form a "laser sword" light saber that is more consistent with George Lucas' original concept.
If the electron density of the plasma is chosen so that the "plasma frequency" corresponds to the laser light frequency, the plasma will almost totally reflect/backscatter the laser light. So, a laser beam projected into a cavity formed by a surrounding magnetically confined plasma of the correct density would be confined in that cavity.
I would go further and have the same gas that forms the plasma also fill the interior of the cavity, but unionized, so that it acts as a laser gain medium with either electric discharge or radio-frequency pumping to amplify the injected laser light. I would put a photorefractive phase conjugate mirror in the hilt of the light saber to form one reflector in this laser cavity in order to correct for the highly aberrated reflections of the laser light scattered from the plasma boundary.
Sooooooo goooooooood! Keep em coming! Love the qna
Normal Body Temp is 36,5 C if the externak Temperature is way higher homeostasis works to lose as much temp as posible trough sweat and other mechanisms, if its the other way around your body tries hard to generate heat. If external temp is near enough to your body temp, but still lower it (your bod) doesn't lose heat so fast and it feels unconfortable.
PS: you didn't get the digiworld question
Isn't the hottest temperature the Plank Temperature, or the temperature when the wave length of the light emitted by the material becomes the Plank Length? Because as the temperature increases, the light will go through the light spectrum, eventually reaching gamma rays and at some temperature that I'm sure someone has calculated before me, the wave length will reduce to the plank length.
Would the absolute highest temperature for any particular object be the maximum energy that the particular object/particle can absorb before the building blocks, atoms, particles, etc of that object have enough kinetic energy for the bonds between them to be broken?
I remember reading that hitting absolute zero is mathematically impossible.
Something that I think can help people more intuitively understand quantum physics are VR games and programs that being quantum level effects into the macro scale, like Sight Line, so you can experience them.
It just sort of makes sense.
why is it, evolutionarily speaking, a good idea to not be able to consume uncooked foods but cooked instead. specifically chicken .
Nicholas Burke, well, the energy it takes to maintain an immune system that can defeat the types of bacteria and pathogens commonly found in and on uncooked food can be used better, evolutionary speaking, towards higher cognitive functions and development. Now, having a digestive system that readily accepts cooked food increases the amount of nutrients absorbed from the cooked food. Consider it ‘pre-digestion’. Adding these two features, roughly, both protects us from deadly diseases, that we don’t need to waste resources beating and maintains defenses to, and gaining and retaining more nutrients from our food. The issue with chickens is, they’re dirty! Like pig dirty! So, make sure you fully cook your food, because our bodies have not only gained protections, but have lost protections, as well.
Salmonella.
Think about the polar bear, probably the most perfect example of evolution. At some point a few bears migrated into snow, some of them had a pigment defficiency (a hindrance in wooded areas) but would have been ever so slightly superior in snow due to camoflage. Eventually this pigment defficiency resulted in them getting more energy - those bred more.
A bit of quantum physics. Things want to be in the lowest energy state possible. Sometimes there is an energy hill in the way. You can "tunnel" through that hill to the lower energy state. This is a big problem in circuits (as electrons can tunnel through insulators at these small distances). You effectively forgo falling down a small cliff and teleport to falling down a much larger one.
Humans experienced multiple "tunnels" in our evolution, evolutionary tunnelling. Fire and cooking was one, not a gradual improvement, but a complete repositioning on the evolutionary spectrum. Tools and subsequently access to bone marrow was another (it allowed us to access food once superior predators were done with a carcass), likely the most important point in our evolution. Intelligence is another example.
We are in such a superior position due to dumb luck. Other species might be tunnelling every day, but to dead ends - rapid progress followed by no possible further progress (the crocodile).
It wasn't a good idea, it was blind luck that prevented another organism from stealing our energy. We thrived. Because we thrived, we bred.

I had a biology teacher who cut themselves on an obsidian scalpel before it was banned. Destroyed all her nerves in that finger with just a small cut.
I wanted to bring up the topic about the flash moving so fast that he "phases" through objects. What if he doesn't just have super speed but actually has control of how fast or in what location every atom of his body is? If so, could there be a state at which he could move his atoms in a way to pass by or "through" the atoms of an object?
I love how smart I feel whenever I'm able to answer one of the questions lol
On the digimon thing another good example would be sword art online in which they use a headset to transfer their consciousness into the games server
In your attempt to talk about the "hottest hot" you mentioned that 0k would be the lack of motion of particles. If that is the case (and it is) then wouldn't the hottest hot be particles moving at the speed of light?
video suggestion: maybe you could also tinker on Mortal Kombat "physics" as well, like would it be possible to perform finishing moves like decapitate a person by just an uppercut, or ripping the head (with spine attached) by just using your bare hands? or how could Liu Kang do bicycle kicks with him just standing there, with ZERO inertia to have him travel in mid-air directly to his opponent?
When Kyle was talking about the VR stuff it made me think of The VOID! Look it up it's sweet
You went to Marquette!? I live a few minutes from there, are you from Wisconsin initially?
There is a limit to how hot something can be, because as the heat increases the wave length of light it emits increases. the smallest wave length you can achieve is the Planck distance, beyond that you cannot really heat anything up as it would be hotter than temperature. it's actually called the Planck temperature, 141,000 billion billion billion degrees Celsius, and because you would need an extraordinary amount of energy to heat something that much, if you tried to put any more into it, it would more than likely create a Kugelblitz. A black hole formed from energy.
When he says "this is all we have". He's not lying!
...we're in the Digi-verse after all. :P
I love the Bob Ross reference!
Barrels exploding is common when filled with things like snow or dirt. Happens a lot for hunters.
