What happened to antimatter? - Rolf Landua

Particles come in pairs, which is why there should be an equal amount of matter and antimatter in the universe. Yet, scientists have not been able to detect any in the visible universe. Where is this missing antimatter? CERN scientist Rolf Landua returns to the seconds after the Big Bang to explain the disparity that allows humans to exist today.

The beauty of Science is that it is not ashamed to admit that it still doesn't have all the answers. Giving us more reason to be curious, to learn and to explore. :)

"Anti-proton" should be called "negatron"

What happened to antimatter? It's simple.
*Antimatter has left the chat*

"What happened to antimatter? We don't know."

Great video...

2013, We just dunno the answer.
2015, We just dunno the answer.
2017, We just dunno the answer.
2019, We just dunno the answer.




Damn.

[nessybomber]

so if I drank anti-water I would explode?

[generalgrevious]

So are matter and anti-matter same?
Ted Ed: Yesn't

[Manabender]

Perhaps all the antimatter went the other direction. Allow me to explain.

(Note that I will be using the terms "east" and "west". These directions have no meaning in the context of the universe, so just point in any direction. That's east. The opposite direction is west.)

When the big bang occurred, immense amounts of particles and antiparticles were made, and most annihilated each other. But, due to random variance, slightly more matter went east, and slightly more antimatter went west. It wouldn't take too long before all the eastward antimatter was annihilated with the dominant matter, and vice versa in the west. The end result would be a bubble of matter in the east and a bubble of antimatter in the west, separated by an extreme distance. Both would have an exactly equal mass.

"mommy, I need a gram of antimatter"
"All right, how much does it cost(at most a dollar)?"
dollars only"

[mothafuger]

Us farming a theoretical planet made up antimatter would be silly. Anything we used to farm it would cause it to explode.

[underOS]

maybe to other living things on the other side of the universe our matter is anti-matter to them and we are actually the ones that are living in an anti-matter world

What if there are 2 universe created in big bang? 1 is our universe which have matter? Another one contain anti matter . Just like the Ying- Yang pattern.

[yafi]

a little knowledge is a very dangerous thing

[JakobVirgil]

if we treat antimatter as matter going in the wrong direction in regards to time then it went out the other side of the big bang.

[nikkitytom]

An excellent presentation.   Clear and beautifully illustrated.   Something which has been frustrating me for a while is now crystal clear.  Thank you Professor Landua.

We are _unlucky_ that tiny asymmetry existed.

[Naijiri.]

But how is that possible? If there is an exact 50/50, there is an *EXACT 50/50*, how could you say there was an asymmetry

[esthera]

Also, who the hell would dislike this video. This is awesome.

[nujranujranujra]

That music at the beginning and ending is

[BrandonSchleifer]

What if there is a ton of antimatter out there, but it's just over 14 billion light years away, so we can't see it?
