What is antimatter? Neil deGrasse Tyson and Chuck Nice break down what antimatter is and how our matter-based universe came to be. What happens when matter and antimatter annihilate? We break down positrons and the anti-quarks that makeup anti-neutrons. Is there an opposite universe where everything is antimatter? Plus, learn about energy mass conversion and its role in how our universe came to be.

02/13/2025 - 4:31 AMHow could the study of antimatter help us understand the origins and ultimate fate of our universe?
@Bernardo-e6d6k
02/13/2025 - 4:31 AMIsn't that penny going to create a nuclear explosion unlike any other since 100 percent of the mass of that penny become energy therefore killing you and them and destroing revers country that you are in the reverse universe
@Dhahdbjdnd
02/13/2025 - 4:31 AMOf matter and antimatter collides and create energy and the anti matter/matter cease to existā¦ then how do the universe create matter and antimatter ? Would it mean that the Big Bang should not exist when all matter get squeeze/collapse before the Big Bang starts.. shouldnāt the collapse of the universe cause antimatter and matter to collide?

02/13/2025 - 4:31 AM"WE NEED A ANTIMATTER BOMB" sure sure let us come up with even stronger device to delete this planet from excistence gotta have prioritites aye… lol xD

02/13/2025 - 4:31 AMI am convinced science will always be in faiths shadow
@mayalhazzani
02/13/2025 - 4:31 AMI love the enthusiasm in this episode ! Absolutely love your explainers
@danielvinhas2054
02/13/2025 - 4:31 AMCan anyone point me to the full episode on this?
@maggiecornelius9777
02/13/2025 - 4:31 AMStill kind of confused. So antimatter does exist, but not in our universe?
@deadtoadsoup
02/13/2025 - 4:31 AMWhy is there something rather than nothing? Because all the anti-somethings disappeared for some unknown reason.
@bwasman8409
02/13/2025 - 4:31 AMAntimatter is the partner of unclematter, their children would be niece and nephew matter! Simple!

02/13/2025 - 4:31 AM0=+1-1
Or 0=+1+1+1+1+1+1+1-1-1-1-1-1-1-1-1
Now.. If.. Some -1 or +1 didn't get its pair.. Then it.. Makes a whole universe.. Out of it.. It can be.. Made with anti matter or matter.. For this universe.. It matters.. (+1)…

02/13/2025 - 4:31 AMMaybe Black holes are waste baskets for ant matter.
@Vineeth_Shankar
02/13/2025 - 4:31 AMWhat does a positive charge negative charge fraction of a charge even mean? I cannot visualise or understand it? How do you measure something is +1 charge?
@GetReide
02/13/2025 - 4:31 AMoh no! step-photon Im stuck!
@BentonNorris-k1z
02/13/2025 - 4:31 AMA photon is a positron and an electron the proof is the quantum leap the positron wants to run away from the electron the election wants to chase the position if this photon hits the right election the photons positron annihilates the electron in orbit the photons electron falls into the orbit because of its high energy it leaps to a higher place
@nealbutler3332
02/13/2025 - 4:31 AMThe existence of the neutrino implies the existence of a neutrina and I donāt think we are studying this enough.
@ASKmeaboutphotography
02/13/2025 - 4:31 AMWell, you wouldn't require a coin to determine if it is an anti matter universe. You would be annihilated as soon as you touch the ground there.š
@FantasyForms3D
02/13/2025 - 4:31 AMDo you think its possible to have a dark matter lifeform?
@doomedoptimism1015
02/13/2025 - 4:31 AMI wonder what would have happened if the anti matter fell into a black hole. My understanding is that black holes wouldn't differentiate between matter and anti matter, gravity will act on both of them equally, and most of the matter that passes into the event horizon is converted into energy anyway, so would we even be able to tell if by pure luck, the anti matter had been gobbled up by black holes in the early universe more often than matter?
@jeremyf.2706
02/13/2025 - 4:31 AM"A universe of pure light" …..hmmmmm maybe heaven is just another parallel universe where the spontaneous conversion into matter was less and most of the universe IS light??? Just a thought experiment.
@Stepbrohelp
02/13/2025 - 4:31 AMI have a theory that I am not smart enough to be able to justify, or test in any way, that antimatter is what is at the center of black holes. For some reason, all of the antimatter clumped together at the beginning of the universe, got super dense, and started attracting all the other nearby matter. That explains why we ādonāt seeā antimatter when we would expect to, and also explain why things can never leave a black holeābecause they are annihilated.
@madanmehta1198
02/13/2025 - 4:31 AMThere must be an antimatter universe
