More Meteorites, Why a Universe of Matter, and Micro-coolers?
This is the last episode in which Lawrence was able to get into the studio before the pandemic made travel impossible. In this episode he first returns to another discovery in meteorites, finding not the oldest
material ever known, but a potentially new extraterrestrial protein that could shed light on the evolution of life in our solar system. He then describes how new measurements of neutrons may shed
light on the origin of matter in the Universe, and concludes with an interesting proposal for the opposite of a microwave oven.. a cooling system that he previously thought was impossible!

I really enjoy LK. He speaks way above my head, yet doesn't condescend. A tricky balancing act; delightful subjects! How very small we all are in the universe, yet somehow magnificent.

I just watched all 7 episodes of Science Matters back to back. Very entertaining three hours to help get through the lockdown here in the uk. Thank you Dr. Krauss I look forward to more. But it got me thinking, there should be a 24 hour science news channel just like Science Matters. It would be better then the 20 doom and gloom news channels that we have already. I would watch it over my breakfast.

I wish I was good at science and could understand science. I struggled in school and then 15 years later started a science degree to try and push myself out of my comfort zone. It's been a struggle and I wouldn't say I'm any better at science for all the pain I've endured. However I do enjoy listening to this podcast even if it goes over my head most of the time.

@georgikrastev 4 года назад

L. Krauss 20 years ago: No, a micro-cooler does not seem possible. Turns out it is - Amazing, I love it when something I thought impossible becomes possible. The submission and acceptance of truth is fascinating as it is. But even more so is the never ending curiosity about Nature. It's what's driving us to the deeper understanding of natural processes. Ultimately it is what science really seems to be. Who framed it like this? Was it Sagan or Feynman who stated that "science is a way for us to net be deceived"? Whoever it was, I have to nod in agreement. Thank you, Mr. Krauss for the videos! You are amazing!

For cooling, you “just” need some nanobots that can identify and separate the high energy photons from the low energy ones. Larry Niven did a SF short story on that, with the last line being “I’d like you to meet my clerk, Maxwell”

Wait just a minute: If there were an equal number of particles and anti-particles in the singularity, why didn't they annihilate one another before the Big Bang even occurred? What was separating one from the other inside of a super-incredibly-densely packed singularity? How did particles and anti-particles exist in such an environment?

@jeffreyhogueison8560 4 года назад

the imbalance through weak decay made the small difference temporary for billions of year so far. The particles that were decayed products do not recombine very easy through time separated. The sum energy mass of universe is still the zero of a quantum fluctuation. K meson neutral decay and antiparticle is not absolute but a wave function 1 in a billion.

@EmergentUniverse 4 года назад

Talking about C, P, T without understanding that spacetime is a particulate aether is nonsense. You must also account for C, P, T of the spacetime aether as well. I suspect that means that all of these symmetries are conserved.

@EmergentUniverse 4 года назад

I’ve since changed my terminology to say aether. Spacetime aether is an emergent structure made from Planck sphere particles. See jmarkmorris.com. Spend some time with my theory of everything before you jump to conclusions. Ad hominem attacks are bad form. Cheers!

@EmergentUniverse 4 года назад

@Alchemist Finding the right terminology is part of science. Gas is a good descriptor for the structure of spacetime. I changed to aether a few weeks ago because Michelson-Morley made a major error and had they not, it might still be called an aether. Remember gravity as a force is dozens of orders of magnitude below the others, and that is why Michelson Morley could not detect it. There is another reason but too long to describe here. Your form of inquiry is not scientific and attacking me or my ideas is only making you into a fool.

@EmergentUniverse 4 года назад

@Alchemist I also wanted to mention again, that spacetime aether is particulate, although a better terminology is that it is a structure made from Planck sphere particles. If you want to get onboard the new era at the beginning, ready my blog at jmarkmorris.com. The GR/QM/LCDM era is over along with their nonsense narratives and misinterpretations.

Forgive my scientific ignorance, but can someone help me. Have the laws of physics always had the same rate of speed since the beginning of the Big Bang? And, the Big Bang is technically still happening, and humans happen to have evolved to exists at this moment in the universes existence?

@tracyrichardson3010 4 года назад

Mainstream says the speed of light has been constant. However, in 400 years of measuring it, it declined. To understand, look for videos by Barry Setterfield on C-Decay (CDK) or Zero Point Energy (ZPE).

@bundleofperceptions1397 4 года назад

Hold the Phone: "there has to be some process that can change the number of baryons versus anti-baryons...." OK, I with you so far, but "it can create baryons where there weren't any at the beginning." That is one way of altering the ratio, but it seems another way might be if there is some other process by which anti-baryons are either annihilated or converted into another form which would leave the baryon without an annihilating partner -- I got rid of my annihilating partner last year, so I know it can be done. (percussion rimshot, please) Do you know for a fact that your hypothesis is the only way it can be accomplished?

@lkrauss1 4 года назад

by CPT the process you are discussing could be expressed in terms of baryons

@franklangelotti585 4 года назад

Mr Krauss....I know nothing about cosmology other than I am told that the cosmos as we know it came from nothing, and that it started with The Big Bang. I am also told that there are things called Black Holes which absorb matter. I was thinking is it possible that our cosmos, universe is the result of being at the other end of the discharge of that energy and material from another Universe and might that suggest that other universes might exist, ad infinitum ?

22:12 'all matter with a temperature radiates, no. Why is it N2 and O2 have single quantum mechanics predicted spectra each in the IR of the EMS (at 1556cm-1 and 2338cm-1 respectively) and these positions are observed or inferred by the modern Raman laser spectrometer (exploiting the Raman effect) and their temperatures measured via the Boltzmann constant, yet both these molecules (99% of the Earth's atmosphere) are assumed not to interact with photons in the IR? They are assumed not to radiate. Has quantum mechanics a contradiction?

I'm wondering what was the process of charge stabilization in early days. Protons/Neutrons with its antimater partners are much heavier than electrons/positrons. So they should be created less often but we do not observe unbalance of charges. Most of them are 'neutralised'. Or we don't know of that? What would happened with additional charged particles in the Universe?

Dr Krause, to call a molecule with molecular weight 2300 a protein is a stretch too far.

@pbredder 4 года назад

What they report is two polyglycine chains of 16-17 residues long. Glycine is an alpha amino acid like the other 20 found in proteins, but it is the simplest -- lacking and functional side chain. Each chain would have a molecular weight of around 1200 or a bit larger. The smallest protein here on Earth is 20 residues long.

I don't think any laws were broken. I think positrons were created in the same number just like every lab test we conduct. I think more antimatter fell into primordial black holes than matter did.
