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]

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]

@@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]

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]

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]

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]

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]

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.

[@derbigpr500]

It's by far the most likely of the explanations talked about in this video.

[@jimwhitehead1532]

Wild guess: Is antimatter simply time-reversed normal matter? One theorem says they are mathematically identical. Also, Feynman diagrams predict brief time reversals in particle interactions. If so, then in the Big Bang, did half the energy as anti-matter go backwards in time, vanishing from our sight and did our matter go forward in time?

[@FCHenchy]

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

[@Sadistichippo]

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]

Then does anti-matter have negative mass based gravety.

I am a software developer but these physicians really make the thing understandable... Thank you guys.

[@kevin_delaney]

As much as I appreciate staying on track, I do find the hypothetical antihydrogen conversations, the conversations where physicists minds wonder, even more fascinating. I think those conversations should be allowed to wonder a bit more.

[@jimwhitehead1532]

Another take: they didn't want to publicly discuss an area of current highly classified research.

[@kevin_delaney]

@@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!

[@jimwhitehead1532]

@@kevin_delaney Remember the Dan Brown book and movie "Angels and Demons" about a stolen canister of antimatter that threatened the Vatican? They cut off discussion right away, to not help the bad guys. IMHO, read the book if you can. It is way better than the movie.

I always get the feeling that at some point in experimental physics, in our effort to discover the true nature of the universe, somehow un-intuitively create a black swan event that wipes us out. I don’t believe it is likely to ever actually happen, but...

[@Ckbtony1983]

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

[@joeblog2672]

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.

Car arms, image recognition, better environmental control in micro bio-domes. Decades of work done in months, addressing combinatorial explosion with intelligent exploration, but some testing. Science works while you sleep. The synchronicity is happening for these people, here, now, in the video. The things I can dream of having read, that I don't have the time to address. I should have studied. Still a happy story.

[@cherrydragon3120]

I mean... anyone could do that. Its literaly just using illustrations and animations that well... less intelligent people CAN comprehend. Unlike them, we never seen a proton before or a anti-neutron. They did. But we all have seen a dog before. So them comparing the anti-particles to dogs makes it more relatable to us qnd thus easier to understand. Like how you know the difference between a Circle, square and hexagon. But a todler does not. Until you show the difference and explain what this difference is. (The amount of corners) :)

[@SilverBee]

@@cherrydragon3120 I'm impressed by your response, Cherry Dragon. I, too, am so happy to have these understandable explanations. I don't consider myself or you as "less intelligent," rather it's just a matter of never having learned certain terminology and maths at an early age. From what I've read, some of the major scientists who came up with foundational theories and hypotheses visualized them first and worked out the explanations later. Seems like that puts us right in there with the big guys. (smile)

There is a fascinating elegance in observing how the caste of former storytellers, magicians, conjurers, sorcerers and necromancers have found a home in the new teaching - what we now call 'The Science'. 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.
