You exist. You shouldn’t. Stars and galaxies and planets exist. They shouldn’t. The nascent universe contained equal parts matter and antimatter that should have instantly obliterated each other, turning the Big Bang into the Big Fizzle. And yet, here we are: flesh, blood, stars, moons, sky. Why? Come join us as we dive deep down the rabbit hole of solving the mystery of the missing antimatter.
MODERATOR: Brian Greene
PARTICIPANTS: Marcela Carena, Janet Conrad, Michael Doser, Hitoshi Murayama, Neil Turok
OPENING FILM: Animation by Eoin Duffy of Studio Belly, written by Justin Weinstein and Brian Greene

This has got to be the best one so far. Could follow along with 90% of the discussion thanks to all the analogies and slides. Got a little lost during the neutrino talk, they set up how hard it is to catch and detect and it being electrically neutral but then at the end they said they just gonna shoot it 1000kms and split it with a magnet... Im guessing their is some explanation that was too hard to communicate in a discussion like this

@benjaminbeard3736 2 года назад

All the particles that are not electrically neutral are removed from the beam leaving only the neutrinos. Or reverse the magnet so you get anti matter and when it decays neutrinos are in your decay product.

@paulmichaelfreedman8334 Год назад

@@benjaminbeard3736 All the charged particles are stopped by the rocks the beam travels through. Where even gamma radiation only travels at most a few hundred meters, neutrinos shoot through the entire Earth as if it's empty space. Neutrinos need a lightyear of lead to stop half of them. They are able to leave the core of the sun in a straight line without ever bumping into a single nucleus.

@collinwalker550 6 лет назад

Getting to the end of this video and seeing Neil Turok's model of the universe was weird as hell... As an uneducated worker, I got into physics a while ago. A little over a year ago, I learned that antimatter was just time reversed matter, and I spent several weeks contemplating this, and then further on the topic of this video: why the universe exists if antimatter and matter was created in equal. I literally came to the conclusion that the big bang must be symetrical in time, and began drawing a model exactly like that of Turok's... but I had never heard of that before. I honestly thought it was just my uneducated imagination going wild and really never took it seriously. But seeing this video now, that some theoretical physicist way smarter than I came to the same conclusion (I'm sure in much more detail), is really mind blowing. This is tripping me out.

@LuisAldamiz 6 лет назад

Well, you're not the only one, Colin: I've also contemplated that very same notion since I learned a bit about Feynman's diagrams, which seems to be what is inspiring Turok after all. He's saying: we've tried to do it all over-complicated and it didn't work, why not go back to "the basics", and, if we do that, maybe it's all a bit simpler an we just can't experience (most of) the antimatter that there is because it is in the "wrong" time direction... somehow. I thinking of that: it can be all kinds of wrong, because my knowledge is way too limited. Some guy on the Internet (i.e. you) saying that: same thing or worse. But Neil Turok saying that, then it becomes authority and therefore quite plausible. Of course he can be wrong as well but at the very least he seems to know what he is talking about, so...

@collinwalker550 6 лет назад

Amar Salih Šehić But without men like Neil Turok, we wouldn't be pushing the limits and possibilities of science. Without pushing the limits and possibilities of science, there can be no experiments. I say if one man has an exceptional ability in a particular area of study, let him work where he may yield the most value for everyone. Those whom are better with the stock market should work with the stock market. Those whom are exceptional fundraisers should be fundraisers. The most value we can get is when everyone does what they are best in rather than trying to fill needed roles with people who are mediocre or not as skilled in that area. Neil Turok is very much needed where he currently is in my opinion.

@NicholasA231 6 лет назад

I agree. When he started getting into his explanation I was thinking oh my god, yes! I also have no physics education, and struggle to understand a lot of the things I'd like to because I don't possess the math to enable those revelations but, even though there are critical details of what I just heard that I can't now explain to someone else, it made an awful lot of sense to me. Not in a metaphysical sort of way or anything. Just in a sense that science seems to often have these build-ups of theory, eventually constructing this contraption resembling Rube-Goldberg's finest, until someone comes along, walks over, and just flips the switch on. Which I guess is pretty much what he was saying. I would almost certainly be an experimentalist if I were in physics, but there is this deep excitement for the development of theory too. I really have no place to even have an opinion on these things, but it's fascinating. I wonder about this stuff and really need to educate myself more deeply. Like, photons don't experience time. From their "perspective" they are born and die at precisely the same instant. Nevermind that we see them maybe 14 billion years after they formed. I wonder things like, does that relate to what he's saying here? Was there an epoch where none of the "stuff" experienced time, then god peeked in the box and poof, okay matter it is, -BANG-? Anyway, cool stuff.

@Jason-gt2kx 5 лет назад

Maybe the mechanism of the black box is the positrons converting into dark matter. I believe dark matter isn't a ghost particle sitting ON the spacetime fabric, but rather positron's converted energy imprinted INSIDE OF spacetime. I think dark matter is empty fixed energy fields creating gravity wells. Spacetime hit a yield point during inflation and somehow the broken symmetry and lost positrons created potential energy in a phase transition. This hypothesis solves two problems and supports the conservation of energy.

The best bit is that scientists calculated differances in temperature in the pre-big bang quantum fluctuations and then , demonstrated the identical temperature differances throughout the CMB (in our universe).

@kevin_delaney 2 года назад

@@jimwhitehead1532 Lmfao yeah, that is most likely the issue. It kills me though because education and innovation is stifled so much because of confidential and classified programs. When I attended school for advanced manufacturing (Precision Machining and CNC Automation) I got intrigued by radioactive machining and superalloy (nickel based) manufacturing methods and it's only ever really used in defense or aerospace applications, it's nearly impossible to learn about. From purely an educational standpoint, it is exceedingly frustrating, as a student that just wants to learn more. I'd love to work in research and development in some of those classified programs, I find physics and that level of chemistry/material science so fascinating!

After listening to this panel speak ( calm, quiet. rational, respectful of each other, clear of thought, etc, etc ) it really makes you wonder what kind of a world we could live in if all of our, so-called, "leaders" were like these people. The idea that people like this could do a better job of running the world might be a concept that is too naive but I find it to be an interesting daydream. I qualify this in consideration that I used to think of Brian Greene as my hero in scientific thought until I heard some of his political jokes that exposed his sub-agenda ( we all know there is much more to jokes than meets the eye ). Who knows what is under the "sheep's clothing" with any particular individual but I sure did enjoy all of his guests here tonight. Neil Turok in particular seems to be an ideal human being. I think I have a new "hero".

@Ckbtony1983 2 года назад

But what if the universe itself has an anti universe and theres a copy of us seperated by a thin veil

@joeblog2672 9 месяцев назад

I think we are allowed by some Creator to comprehend so much of the nature of the universe at so much a time. Most of the advancements in science over the centuries has come about not from outright wrongs or complete errors but from highly accurate foundations which are simply limited in the scope of their application. Probably the best example of such is comparing Newton to Einstein. Newton's formulae to explain gravity are near perfect when describing macroscopic entities in motion but they fail when taking into account heavier masses and speeds. Newton's math was far more responsible than anyone else's advanced math for NASA getting men on the moon and back. Then Einstein comes along and corrects Newton's gravity math while also providing a better picture of gravity as being defined as the curving of spacetime by mass (and thus energy too). But now quantum mechanics comes along and says "Hold on you Einstein. Your gravity math doesn't work at my level". Unfortunately QM hasn't revealed the true nature of its gravity math (the elusive quantum gravity). Whoever figures this out will be the new Einstein, just as Einstein was the new Newton or Galileo if you prefer.

If we live in the Infinite Universe, this is evidence of the existence of the woven universes Please send my three questions to cosmologists .

With a grace that almost gives the appearance of believability, they are able to take us away from the triviality of our everyday thoughts. They strive to introduce us to the dazzling spheres of actual reality and to reveal their pulsating dance to us.

What if antimatter reacts the opposite to gravity so it makes things anti move away from things of large positive mass. Does that make sense???

@FCHenchy 4 года назад

It's something they are trying to test. Most theories fall on the regular-gravity side, though.

@Sadistichippo 4 года назад

The difficulty with going down this path is that gravity is a big unknown in particle physics. We simply don't have a solid model for gravity on a quantum level. And without a solid model, it's hard to build theories and by extension experiments. Your theory could well be correct, but so far our testing seems to show gravity affects matter and anti matter in the same way on a macroscopic scale.

@laurieslaathaug4600 4 года назад

Then does anti-matter have negative mass based gravety. If most of an atoms mass comes from neutrons, with no charge, could it be possible that neutrons are interchangeable between matter and anti-matter? As with no charge they should, in theory, be interchangeable. A corection may be needed, if possible, type below.
