- In this episode of Science Matters we revisit two familiar topics, the mystery of where the earth's water comes from, and measurements of the cosmic microwave background radiation, and demonstrate some new and exciting results. We then turn to the weird quantum physics of strange materials, where electrons can act like they have no mass, and conclude with some fun new options for living on the Moon or Mars.

Science is the only harbour for sane people in this ever increasingly insane world, please keep us sane Laurence.
Science is the only thing that gets respect for being dead wrong or proposing out there ideas.
@@carlosoliveira-rc2xt Yes, science strives to be more and more precise. It does not mind changing in the face of new evidence.

Science matters!
Science matters indeed! An informative episode. This ability to simplify and explain the data in a way that a potato brain like mine is capable of understanding is the most marvelous of all things. It's the true testament that one understands his / her field. Thank you for this series!
Just wanted to thank for your great effort to bring us the huge amount of Information .
Excellent! Thank you
Thanks so much for continuing to do these. Listening to this as I stand in line to cast my vote for science!
I needed a dose of science this week. :)
HI Lawrence! How did it take me so long to find these videos after watching your 5 minute physics lectures!!?? Well, that doesn't matter. I am glad that I finally did! So you wonder if anyone finds this stuff fascinating...? I live for this stuff! Don't always understand it, especially the equations, as I am a bear of very little brain. But I can just soak this knowledge up. Anyway, happy I finally checked this out. I will be going back and watching more. Still waiting for the pandemic end so you can take a trip to the Boston area and sign my book, once I get a copy from the store! Great stuff!
What a lovely view from the windows👍 It’s great to be surrounded with green.
Yay, sweet, more science!
I'm so glad, thought the episodes were all done
Lawrence I’m sure it’s said plenty, but bless you for these videos, one of my favorite science communicators, top 5 for sure. Thanks for making this stuff paletteable for simple apes like myself.
Thank you Dr. Krauss for the new lecture! Miss the Origins Project stage events!
me too.. stay tuned..once the pandemic ends
@@TheOriginsPodcast Yes, can't wait. Thank you! I have watched the Story Telling Of Science at least 20 times, every time there was new takeaways!
I find that, pretty much everything that you talk about is, fascinating! Thanks for doing these and also for the 5 minute physics lessons as well! Fascinating!
This was a tough one. Good challenge!!
Thank you for all you do for Science and our understanding of it.
Lawrence is awesome.
One of the few on this planet that can explain to us normal folk how the universe works.
And make it fun and understandable.
You really think they know how it works? LOL! They know nothing. They explain how they think is works, but this is not how real universe work.
@@Kintabl 🤣
@@theoneandonlyroelle So you think they figured it all out about universe? LOL!
@@Kintabl There is a point here, and you're not getting it.
@@Kintabl Wow, you've convinced me! Science is a sham! So much time wasted studying and thinking 🤦
Nice bunch of explanations porfesssor. Following you for a larger bunch of years.
Beautiful! It's actually exciting what's possible when we did deeper. Like when we study the properties of the small, we are better able to shape the large.
Professor Lawrence Krauss,
All my respects, love and admiration for you Sir.
I love your lecture even though I do not understand much, for I love science.
Hi Lawrence! Good to see you again, just found this site so will be a regular visitor from now on!
Great explanations!! Thank you! Undoubtedly fascinating to me too!
Beautifully done professeur, hope we could see u more often.
Yess I've been jonesin' for a new science matters!!! Thank you Lawrence 💝
Thank you sir for doing this for us. Amazing.
Thanks a lot. Professor Kraus is one of my favourite educators!
Thank you very much! I am always thirsty for knowledge
Espectacular!
Extremely interesting episode. Thank you for all your hard work on bringing these interesting discoveries to the wider public.
I great appreciate scientist like Lawrence Krause
Great Mossy Thoughts!
Beautiful
Good, good, good, good vibrations!
Love the lava tube idea: Cave Men On Mars!
Very complicated. Thanks for the food thought. In my mind, the microwave radiation is easily reflected and mirrored by matter so it's all a bown soup of reflected microwave sources. That's why the CMB is so blended and smooth
Velikovski lives! I’ve long wondered about primordial oil, given what Titan looks like. And wow, I’m colourblind too, to a degree . But I never wore red shoes. . . 😀
The rungs of the Distance Ladder are made from Balsa Wood
This is a brilliant show thank you Lawrence
I wonder if it is possible to say more about Dirac Sea
Why if an electron moves a positron is also created?
What is it moving through or across?
Thanks for this episode.
- The water subject, interest wise, seemed a tad lukewarm to me…
- The Cosmic Radiation info was pretty cool (Pun fully intended considering the actual temp of the stuff. Brrrrr.)…
- The Strange Material bit was super exciting and illustrates the many possible wondrous things we should be able to do in the next century (really looking forward to moving above the earths grounds on a hover board! Just kidding! or am i…? ;) )
- Home on the moon : Nice but I’d rather see some improvements down here on earth., as there is soooo much to do and learn.
Overall, very nice episode indeed.
Thanks M. Krauss. :)
Is this anything like free positive holes in a semiconductor?
On the source of water on earth, I'm always taken aback by the notion that 'all' water came from one source... why not multiple sources? Isn't that more likely? The other part that grates against skepticism, is with the abundance of both hydrogen and oxygen in an accretion disk, one would think there would be plenty of both on Earth as well as 'sparks' (energy) to combust the mixture into water. Next, does a hot Earth really mean that all water would boil off into space? And as reactive as hydrogen and oxygen are, wouldn't there be plenty of reactions forming solids that would sequester both for later release and subsequent recombination into water (rust comes to mind)? It's cool that we have this new idea and it sounds very possible if not likely, but how likely is that 'The' source? Just thinking out loud here! BTW, I've missed you in the Atheist community, Laurence! :)
The Miller-Urey experiment was missing one thing....sound (vibration)
That's my theory and I'm sticking to it
I cant wait for the James Webb data
Nowadays I always fear when opening these kind of "science matters" channels that I would find another Ben Davidson talking over there and giving his opinions as scientific facts... But thank God - if he/she exists - it is not always like that. But OK, thanks to Ben Davidson I have got familiar with some "non-main stream" physical theories. But it is not a matter of one's personal opinion to decide which theory is the correct one. It is about plain scientific inquiry done with scientific methods. And there is no such thing as "mains stream" science. There is just science and a quest to prove scientific theories being the correct ones through observations. But thank you for this kind of channel where one presents scientific facts of today.
@Retractions Predicted If you mean the honoured Lawrence M. Krauss - yes, most of the observations made support the scientific theories the scientific community has accepted as relevant scientific theories. Then there are observations that the scientific theories can't predict, but this is the situation at the moment. The theories will evolve, even new insights might be introduced, but that is a matter of science and scientific method to decide - the "interobjective reality" of the scientific community is the decisive factor. Anybody capable of doing scientific research can join the scientific community. You don't even have to be a part of this community to do plausible scientific research. You just have to introduce your results in an acceptable way by which the scientific community can verify or falsify your theory. It just seems that there is a growing trend of an idea that "everybody can do scientific research". Yes, that is a fact. But first you have to educate yourself.
If you mean Ben Davidson... What has he done? Some "scientific research" of the solar polar magnetic field strengths affecting earthquakes, where he totally misinterprets data available from Mount Wilcox Solar Observatory. He just can't understand that the "sine wave" behaviour of the raw data is a true "measurement error" caused by the relative shifts of the solar polar areas compared with the detecting instrument here on Earth, during the movement of the earth around the sun. It is not about the true field strength changes of the polar magnetic fields. With that considered, all the correlations between the solar polar field strengths and the earthquake events he introduces in his research disappear. Of course one can study the possible relationship of the solar wind and earthquakes, and introduce the idea and model of the coupling of magnetic and electric fields around the earth affecting the Earth tectonics and earth quakes. But this can be done using truly scientific methods and models based on fundamental physics.
Then he introduces theories of the "plasma universe" and "plasma cosmology", even the "electric universe". Well, we can state that the universe is plasma universe, and perhaps there will be research and debate if there is need to reconsider the relationship between gravitation and - say - magnetic forces affecting the behaviour of the universe. Once again, this will be done using scientific method. But the plasma cosmology concept has been introduced some 50 years ago especially by Hannes Alfven. But I really don't know if the theory has any better explanation for the behaviour of the universe. Seems that there is no observational evidence supporting the plasma universe theory as a better theory compared with the Big Bang model.
And then there is the micro nova theory introduced by Ben Davidson and other "Ben Davidsons". Wild theory with not a single direct observational proof for a possible behaviour like that of the sun or any other star - according to Ben Davidson the Sun will burst as a micro nova every 12 000 years. And not a single plausible physical theory to support this phenomenon.
Ben Davidson always emphasizes the bad results made in "main stream" science research, or the evidence of those results that support his "scientific research". And how the "main stream" science is totally politically biased sociological phenomenon. But I claim that the only "bad science" is made by Ben Davidson, and political and religious beliefs are the supporting structures to have him "faith" when struggling against "main stream" science.
And last but not least: the "Suspicious Observers" community resembles a religious community. Ben Davidson is next to God and Jesus, the community is a closed one - no debate, and they even have a "confession of faith" of their own. It is in the end of one video. Not interested to link it over here. PS. Nothing bad to say about God and Jesus. Especially Jesus has some great thoughts about ethical and moral issues.
Should one be worried of phenomenon like Ben Davidson? I don't know. He is in margin. But it really seems these kind of phenomena are getting stronger. Especially with the help of the internet.
Eyes open. No fear. Be safe everyone. Support views based on scientific reasoning.
@Retractions Predicted Don't you have anything else to say? Counter arguments? Please tell me, for it is unclear, do you support the science of Ben Davidson, and why do you support his science - if you mean Ben Davidson by stating "all the evidence supports him". As far as my opinion asked, Ben Davidson is just a good liar - just like a good lawyer should be - and he gets good money for being a good liar. But that is how fake science is made.
@God Emperor Donald J Trump Dear. So you have changed your RUclips name. That's fine. So now Donald J. Trump is next to God. If you like it that way, So Shall It Be. Does God exist? Seems that he isn't, according to science. But let's keep the hope, for according to thoughts of Wolfgang Pauli and K.V. Laurikainen, the question is not that easy. Pauli, a Nobel laureate in physics, Laurikainen interpreting thoughts of Pauli. According to them, science has no power to decide whether God exists or not. But behind that there is that deep philosophical thinking. The thinking that only a true scientist is capable of. Comparing their ability to think to Donald J. Trump... well, Donald is just complete BULLSHIT.
Thank you for the again beautiful and important summary
of these interesting physical things.
That the origin of our water on earth is in a certain sense
still a bit of a mystery. And how we can draw fantastic
conclusions from the Cosmic Background Radiation, if
constantly more exactly and more finely examined.
Since we would like to have new and better material at our
disposal, which is as yet unknown, but which can nevertheless
be used in decisive techniques, the investigation you describe
of their sometimes strange behavior is very important.
Topology as property creator. Yes, do these lava tubes exist
on a large and small scale? We think that we can use them
as shelters for our astronauts and the first colonies of
explorers and settlers.
So you immediately think: is this a return to the origins, to go
back to where man found his first home in the early
days of human history?
In this context, let me also point out a phenomenon that
concerns me very much.
Although understood by and large, an elementary question
of origin and whereabouts seems to me to call for an
elegant solution. Yes, there are individual solutions, yes,
there are also combined and arranged and linked ones.
But that is a personal view, that is, one could say, an
aesthetic preference. So we have enough examples for
that, don't we?
Doesn't psychology even study and speculate about whether
it is a matter of natural science at all? A matter far beyond
physics and its strict standards and laws?
It is the question, often swept under the carpet, what the
arrangement of naturalistic representations of living beings
in the video is, if you look as a viewer, in the lower left
corner of your video picture.
Namaste and Auf Wiedersehen.
I wish to an unpresent god that I had at least the intellectual capacity to understand what this man says on just his basic, first run-throughs.
@Retractions Predicted let me guess, you're a hindu?
Mr. Krauss, what are your thoughts on theories such as Scale Relativity? Or, the continued search for 'Relativities' in general (that either sit along side Einstein's theories, or seeks to replace them)?
Man..so much good stuff here!! Your a great science tour guide!! Great pics too!! I would love to see more stuff like this! Why is no one talking about long term Mars stay with out magnetic field? Lava toons though..thats smart!
So Prof. the idea of the amorphous by phase change becoming conductive or not, could an array of lasers be used to construct a CPU?
14:20 Thats what weve been saying this whole time!!
more pls
Hello Dr. Krauss could be cool and helpful to use universe sandbox 2 for some explanations / simulations when it comes down to universe :) Anyway keep up the great work .. always looking forward for a new episode of science matters :) have a nice day
laver tubes and the strong force is our 5% a fractal on the wall??
Hi Prof.krauss. i ve a question (which is very confusing to me) , would you please explain your view to " Why expanding our universe is against second law of Thermodynamics"? ... will be great if you can make a video for that . i am Moe.thanks.
the expansion of the Universe is mostly adiabatic.. and is a perfect example of the 2nd law of thermodynamics at work. We use it to calculate most quantities in cosmology.
I’m colour blind too! The students I TA are always surprised during the lab on sex-linked variation that I can’t see the letters.
Cool how this cosmic background radiation image, does not much differ from an average dirty laptop screen ;)
When will Lawrence appear in Michigan
I’d be first in line to attend!
At UofM, MSU, Fox Theatre???
Thanks that was great! Some good news for a change, please do a q&a sometimes professor. On that note 😁 As light can have a effect on a lightsail does sunlight have any noticeable influence on the orbit of planets and/or the expansion/acceleration of the universe?
alas, no... not really.. pressure too small and planets too distant.
@@TheOriginsPodcast wow didn't expect that thank you. I was sure there would be some effect.
Lawrence I am a huge fan of your body of work. But over the years I have heard this lecture many times before on the web. It is good. Some new material would be good. What do you think of the Many Worlds or Hugh Everett interpretation. Sean Carroll has put some convincing arguments out there. What do you think? Please take care of yourself during this time and all the best to you.
many worlds is 60 years old.. nothing has changed, and it is no more interesting than it was then.. I prefer newer stuff
@ 33:19 Hello anti-gravity!
As my self see CMB it is light refracted by the systems and most of it it comes from the ultraviolet that surrounds or bisible universe.
Is there not a problem when petroleum entering our atmosphere? Will it not set on fire and not reaching the earth in the original chemical formule when it came from space?
Albert Jan Harkema it might have arrived before the exsistence of Earths atmosphere
what happens when the space around a black hole is expanding faster than the speed of light?
Love from Afghanistan
Our planet created all of its elements by itself through its entropy from a mass of quark-gluon plasma to a rock. This happens at the surface of the star where dark matter gives the mass back to the plasma. Plasma needs no catalyst to exist so the core will always cool last. Plasma creates a crust that finally protects the atmosphere from the energy of the core. Now, the process to create water begins. Venus is a portrait of our previous planet and has an atmosphere at 1,900 psi. currently. As the heat of the core cools, the atmosphere gets refined and the water may or may not be able to form as liquid. Venus will undoubtedly have water in the future just as Mars used to have it. We are right in the middle.

This video is a one long tungue twister
Please interview Bernardo Kastrup.
The flat earther's were on the right track but didn't take it far enough. It is the universe that is flat!
Sup from Toronto
Aren't there lots and lots of quasars throughout the universe that would interfere when capturing a "map" of the radiowaves of the sky? Are they filtered out?
not really.. the radio waves pass on average through the universe without significant interaction
@@TheOriginsPodcast I mean, quasars *produce* radio waves, right? So it would become part of the readings.
@@antiHUMANDesigns Yes, there are lots of sources - almost infinitively many - in the universe that emit electromagnetic radiation in the whole range of the electromagnetic radiation spectrum - from radio waves to gamma radiation. But this microwave background radiation is nearly isotropic radiation entering the measurement devices from all over the space - regardless of the direction one observes. So, it must be emitted from a source that was "all over the place". The best scientific explanation for this radiation at the moment is that it originated from "whole of the universe" during the evolution of a young universe. The best scientific explanation at the moment means that there can be alternatives to this explanation. But one should create a plausible scientific theory that is a better candidate to explain this microwave radiation.
But please do read a little bit about measuring the radiation: iopscience.iop.org/article/10.1086/422517/pdf. The article is from 2004, so perhaps it contains a little bit of outdated information, but still explains the method of the measuring technique.
But yes, really, one can measure just the wavelength of this radiation, which peaks at 1,9 mm www.sciencedaily.com/terms/cosmic_microwave_background_radiation.htm . If I correctly remember, Penzias and Wilson, the two that discovered this radiation, tried to measure something else with their antenna back in 1965. But then there was that constant noise. They tried all kinds of tricks to get out of that noise, even washing the antenna thoroughly to get rid of bird dirt that they thought could cause the noise. But finally they just had to state that the noise was over there, "from here to eternity", with a wavelength of about 1,9 mm.
@@jarmokanerva483 I wasn't implying that there was a methodological problem, I was merely wondering if they are able to filter out sources of radiowaves, or perhaps that they don't make enough of a difference, or something. Just being curious.
why is the floor of the lava tube flat?
Love this stuff. You lost me when you started talking numbers in strange materials. My brain doesn't do numbers.
No mention of the black hole-related Nobel prizes in physics?
those results were discussed in an earlier episode, before the Nobel.
@@TheOriginsPodcast Oh, must have missed that episode. 8[
Merci pour ces vidéos instructives.
Votre récent passage chez La Tronche en Biais était très bien aussi.

This cosmic radiation background is not cosmic background at all. It's the noise of our galaxy and distant galaxies, but ''science'' somehow erase all the noise of our galaxy and noise from other galaxies. It's just like taking a picture of house and then erase the house in Photoshop to see what is behind it.
Can you please explain your view in scientific language? How do you interpret the measured microwave background radiation as "noise of our and other galaxies"? If you can't, then you are in trouble with your explanation.
@@jarmokanerva483 This one is gold.

So.. there could be oil on Mars then ?
Is this episode not available as apostasy?
Fascinating as always - thank you!!
PS: I still object to your interview with war criminal David Frum
PS2: why red band on the hand?
Hey Lawrence, I'm sure you have more fat fans than me. Please consider adding XXXL to your Teespring Tshirt. Oh, and thanks for another great presentation!
Yessss liked 1st lol
Why do young people care who makes a comment when, instead of the actual content of the comment?
If you were first, you’d be 13.7 billion years old. So, ummm, no.
Yup we will colonize the moon and introduce Covid19 to celebrate. :-))
Tell us about how the universe is held together by electricity instead of gravity. Tell us the places where Einstein was wrong. Do you not know?
There;s a crisis in cosmology. Tell us about the crisis. Can you tell us where oil came from? It's not from fossils. Tell us how the Grand Canyon and the "lava yubes" on Mars were formed. You're weak, stuck with trying to explain 2021 science with 1975 beliefs cum popsci-baloney. Doesn't work, Lawrence.
@@LewdCustomer well, seems that the explanation is right over there: The Electric Universe. While mr. Krauss is not the supporter of the Electric Universe theory, he hasn't have to explain anything regarding to that theory. Yes, the explanation is over there, but all the facts - the observations that the electric universe predicts - are all missing. Just waiting for the evidence. But we can always listen to and watch Ben Davidson. He has the TRUTH. Because he is a hell of a businessman and a lawyer.
Yes, a harbour for sane people until you listen to the people telling us that gravity does not really exist; that the earth is accelerating beneath our feet anywhere on the planet; that there are no gravitational fields. This does not seem particularly sane to me.
as you said .. because i cant draw 3 d curved surfaces .. it almost sounds kinda sad that you cant do it or let say .. unhappy :D almost apologetic as if its not your fault well in fact it isnt your fault but that made my day as if someone actualy would be disapointed because you cant
on a personal note totaly out of context but still relevant we should ban religion altogether .. and if people have a problem with that i actualy dont care its also illegal to kill someone ... (well in most cases) and everyone seams to be ok with that rule too .. so there ya go .. most of them are not heard by their god anyway if i imagine all those pesants praying on their carped towards some arbitary point in the sky since mekka or what ever the point is they are supposed to pray towards is not even close to their point of praying due to the curved surface of the earth .. .anyway ..
Flat Universe theory!
Don't tell the yanks there is oil out there for goodness sake... Or actually....
um,... I'm a moron,... but wouldn't fossils in asteroids indicate that there was life on the asteroid, or the original source,.... life being plant or animal?... can someone clarify this for my dumb ass lol
He said organic molecules brought water here, i.e. molecules containing carbon-hydrogen bonds. This doesn't necessarily mean something that lives or has lived. Organic molecules are a precursor for life but by no means the only required condition (as far as known now).
Not a great look.
I respect you alot but I like the old look of you can you please cut your beard
