The beginning of the universe, for beginners - Tom Whyntie

How did the universe begin -- and how is it expanding? CERN physicist Tom Whyntie shows how cosmologists and particle physicists explore these questions by replicating the heat, energy, and activity of the first few seconds of our universe, from right after the Big Bang.

We watched a bunch of TEDed videos in science class today, and everyone seemed to enjoy them. Great work, and thank you!

Ugh....I'll be long dead before anyone knows the origin of our universe. Dammit!!!

[hsun_chen]

For some reason I was expecting something like "Our whole universe was in a hot dense state" for intro

[OliverBack]

For people who want to know more:

It wasn't the fact that the universe was really hot that atoms couldn't form, it was the high energy photons, known as Gamma rays, which would collide with the electron and 'knock' it out of the orbit around the nucleus, and the photons would hit the gluon, which is the gauge boson for the strong nuclear force responsible for holding atoms together.

This video made me feel like I am a small kid, learning about universe!

Who came to this from their online classes?

[OLDACCOUNT_notfireman]

Thanks to my teacher, I was forced to watch this Video. Luckily, I like the channel itself so thanks TED-Ed for helping my school-day better.

These kind of animated videos help me greatly understand concepts like this because of my Astrophobia.

why do people take the time to watch a video about the big bang then brag in the comments that god created everything

[claudeleblanc]

Continued...since it's almost beyond question that the universe had a beginning (including the beginning of time, space, matter and energy), only something (or someone) timeless (eternal), immaterial (spiritual) and not limited spatially, could create it.

I've been pondering, and would like feedback. It is reasonable to suggest that in order for something to be a cause to a subsequent effect there needs to exist the medium/dimension of time. So if time only started/came into existence when the big bang occurred and did not exist 'before' the big bang then it would be reasonable to draw the conclusion that the cause, the big bang, does not itself require a cause, (a prior cause is not even possible) given the absence of time, as the cause-effect dynamic was only set into motion once the big bang occurred. Since our cognition can only exist and operate in a cause-effect reality would it then be reasonable to say that we are destined to grapple with the origin of the universe for eternity as no explanation our mind can create will ever be compatible with the events that occurred those 13.8 billion years ago?

Lemaitre identified the expanding universe in a paper two years before Hubble published his work. Lemaitre is also the originator of the idea now known as the Big Bang, a derisive appellation coined by Fred Hoyle nearly two decades later.

0:35: probably a good thing. BRO IT CREATED LIFE

[BlazzingSaber]

I really hope one day everybody will have enthusiasm on the great fields of science.

[Handmadenerd]

Thanks for the video, keep them coming and maybe one day we can all be half as smart as you guys

[chinemeremohaeri]

If we used beginning as is, beginning will become a general concept on its own and it would be treated as a measurement. It occurs everywhere and the beginning of the universe could be at any point considering there's no such thing as time.

[William_Burns]

Wow, I do so regret reading the comments on this video.

[fivedollarsworth]

all i know is when i listen to the signs that the universe reveals, everything is well.

[OrbTheCritic]

I believe I was "created" to be curious...and I really appreciate this explanation...well done!

Excellent explanation, mainly the part that explains the early universe and the connection of high energy in the behavior of the particules. Now, i understand how function the LHC.
