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

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.

Take notes...with actual pen and paper...deep, detailed notes, and study them daily. Add to them. Form your personal belief in what you are learning, make it mean more than just an interesting idea. Come up with arguments supporting your beliefs...then come up with arguments against them. Parse them deeply. At least, thats how I try and gain and retain knowledge.

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.

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

5 жыл бұрын

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...

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.

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.

I think you are talking about string theory? There are places like Cosmic Queries Star Talk or Sam Harris Ask Me Anything, you can send in questions.

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".

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?

Well thank you for this. It explains what can be seen with the naked eye. The picture at beginning helps. Except that they both intermingle together in a semi weaving motion around each other not cancel each other out.

Matter: the basis of all nuclear reactions Anti matter: to doesnt react, I picture a car battery a positive and a negative. So pos and negs are flying around with the charge of dark energy until they come close together and touch they then annihilate same with a battery. You get an electrical shock depending on the wattage of the battery lol I wonder what sends this positive and negative in directions without an original destination/purpose? What if they have a purpose? Is there some sort of genetic code for matter and anti matter? Do they abide by an unspoken law that we don't know about? Yes. They already keep a distance and are opposite. Sometimes opposites attract but those are the weaker and most defected ones who don't survive and go on to evolve abiding by the laws of evolution. I love thinking about these things. You guys are amazing. I hope life is treating you very well and you're all doing great. Stay safe. Thank you, Megan Nickle.

The guy in the middle reminds me of Mark Ruffalo's Bruce Banner, which might take this to a 14/10.

This is second part of Entropy, which includes entropy in terms of arrangement and probability. Suppose there are three color balls, r(red), g(green), b(blue) arranged in three places available for them. So they arranged like; rgb, rbg, bgr, brg, grb, gbr. There are six ways in which they can arranged this is permutation. If one more different color ball or place is added, pernutation or number of arrangement increases to twenty four, that is four multiply to six previous arrangements. Now as there is no preference of any arrangement and all are equally likelihood, so probability of any one selection is 1/6. Thus we see that probability of any selection decreases with increase in permutation or arrangements, and which is related to number of particles or participants which is ball in this case. Decrease in probability is increase in uncertainity or randomness or chaos. Now if in above case if two of ball are of same color, suppose there are three balls of two colors r(red) and b(blue). Then above six arrangements reduces to three; rbb, brb, bbr. So when particles becomes indistinguishable, permutation or arrangements decreases and thus probability of any one arrangement is increase. This type of permutation is equivalent to combination of choosing two balls from three balls of different colors. Probability distribution function of maxwellian particles which are considered as distinguishable is given by suppose, 1/X. Where X is permutation of particles. Similarly permutations of fermions and boson are X+1 and X-1. Both fermions and bosons are considered as indistinguishable particles but their probability distribution function is higher than maxwellian for boson is okay but lower than maxwellian for fermions shows that fermions are distinguishable particles and that is indicated by their spin half property which is basis for exclusion principle. Does there are three kind of particles, two of them are governed by quantum statics or there is one kind of particle given as classical one and there are three kind of distribution density states. Suppose permutation of particles having given higher energy is X, then its probability density function is given by, 1/X. This is known as Maxwell-Boltzmann distribution function where it gives probability of a particle having given energy at temperature. On increasing temperature, probability of particle having given energy increased. Probability of a particle having given energy is 1/X and probability of a particle to not have given energy is, 1 - 1/X or (X - 1)/X. Now ration of a particle having given energy to a particle not having energy is, 1/(X - 1). This is known as Bose-Einstein distribution function and it tells about probability of a particle to have given energy if there is no particle have that given energy before or say ratio of probability of a particle to have given energy to go higher energy level to release given energy to come back to lower energy level. In textbooks it is interpreted entirely different. Again probability of a particle having given energy is 1/X, and probability of another particle to have that same given energy is, 1 + 1/X or (X + 1)/ X. Now ratio of a particle having given energy and another particle to have same energy is given by, 1/(X + 1). Thus the probability of a particle having same energy as by another particle is decreased to if that energy is not occupied. This is known as Fermi-Dirac distribution. So we see that there are no more two other kinds of particles obeying quantum statics but conditional probability distribution of same kind of particles.

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.

As with no charge they should, in theory, be interchangeable. A corection may be needed, if possible, type below.

The First State of Quantum Gravity (or Dark Energy Field) is the Crystal Core we are entangled in - The Crystal Core of the Black Hole in the Universe "Above Us" The Second State of Quantum Gravity is the Wormhole from this Universe to the Universe "Above Us" The Third State of the Dark Energy Field is the Void. The Void is referred to as the Dark Energy State - Dark Energy is Space - Space is not empty nothingness, Space is basically a Superfluid Liquid Crystal Structure that forms up one half of the Universe - The Universe is a Binary system, You have "Space" or more precisely "Dark Energy" and you have Matter/Energy - their interaction is the foundation of the Universe, Time, Gravity, Etc The 4th State of Quantum Gravity is the "Dark Matter State" - This is the State where the Galaxy creates a "bubble" around itself within the Void, where there is MORE Dark Energy outside the bubble that inside the bubble - All Matter/Energy is actively "PUSHING" on the Dark Energy Field with its Electromagnetic Energy - the Galaxy "pushes" against the force of the "Void" or the "Dark Energy State" with its Electromagnetic Radiation Energy - This Energy eventually decays and actually turns into more Space/Dark Energy! The 5th State of Quantum Gravity is the Crystal Iron Cores of the Cosmos, the Stars, Planets, Moons and Protoplanets, the "Cores of the Cosmos" are Crystal Core Quantum Computers, These Cores use their Electromagnetic Energy and create a "bubble" around themselves, where there is MORE Dark Energy on the outside of the bubble than inside - the Cores of the Cosmos form up the "Surface" or the "Surface of Life" - Man, or the Humanoid is the Primal of 5 - the Evolutionary Descendant and form the Cores chose to create as their "vessels of flesh" The 6th State of Quantum Gravity is the Surface of the Atom - There is More Dark Energy on the outside of the Atom than inside the Atom The 7th, 8th and 9th States of Quantum Gravity are the Shells within the Atom The 10th Quantum State of Gravity is the Black Hole, which leads to a new set of Quantum States of Gravity! The Crystal Core of the Black Hole leads to a new Universe - Universes within Universes To understand this, how the Universe creates Gravity and Time, you need to understand that "Time" is the Interaction of Matter/Energy and Space/Dark Energy - so the MORE Dark Energy interacting with Matter, the More Time can occur Gravity is the Electromagnetic Force Matter exerts on the Universe, on Dark Energy that creates a "Dark Energy Field Effect" or Gravity - what that means is that Matter pushes Space away from itself and Space pushes back, as each piece of Matter gets close to each other, their "Distortion Fields" touch each other and so this creates a "Path of Least Resistance" and Pushes Matter together - Dark Energy is Pushing all Matter together! "Does Space have Density" - YES - That's why we have "Gravity Waves" - So, the Denser the "Space" (which is really Dark Energy) the more Time can occur, the less "Space" the less Time can occur Motion of Matter Equals Gravity Equals Energy (Plus about 10%) - It's the very motion of Matter over the Dark Energy Field that creates the Electromagnetic Energy - so the FASTER MATTER IS MOVING THE HEAVIER IT GETS The FASTER Matter moves, the the MORE Electromagnetic Energy it produces - therefore the more it pushes on "Space" and therefore the harder space pushes back - this is Gravity The FASTER Matter moves, the MORE Electromagnetic Energy it produces - therefore the more is pushes on "Space" the LESS "Space" is interacting with Matter, and Therefore THE LESS TIME!
