This guy is amazing. His explanations, his obvious enthusiasm.. all of it.

Could have done with this lad as my science teacher I would have actually liked it

Behold the teardrop climbing a waterfall on its quest to find it's origin beyond the clouds....

I love listening to Brian, and what he talks about it's so amazing

One thing I never understood, if we can look back at the light from almost the beginning of the universe, then that must mean we have been traveling away from that point at basically light speed, otherwise that light would have overtaken us and could never be seen by us again right? So has our galaxy, factoring in the stretching of the universe, practically moved from the location of the Big Bang at light speed? Would love to hear an explanation to this from someone, as I can’t quite wrap my head around this.

sweet dreams are made of these, and we are all made of stars

Whats cool is that ALL space is expanding, ,Your walls get a little further away every second, but you expand slightly every second, its not just "Space" space thats expanding,

[Aguijon]

Paradoxically an infinite and a finite universe would look the same.
In both cases you will reach a point from which you can't observe anything further and left wondering what is beyond...

[JamesBaylockJr]

My feeble mind cannot understand the logistics of how the Webb telescope sees the early Universe 🤯

[cllibutti]

We are living in history. I am old and have been dreaming of this since I was 8yrs old, lol... Will. Die before it's accomplished... Pisses me off... exciting future.

The fact that our current technology is capable of discovering almost the formation of the first galaxy after the big bang, I'm convinced that very soon we will develop something which will really see the very beginning of the first galaxy and surely reach till the big bang.

whether it's an issue with our standard candle model or whether or not it's just a matter of it existing on the other side of what was once the center of the universe (making it go away from us faster than anything else)
or maybe just in the early universe it was easier for there to be more matter anyone given space to be able to collapse down

or whether or not there was some kind of gravitational lensing that has an effect on it that made something that's a size of a solar system be magnified into seeming like a Galaxy..
or whether the universe is actually just slightly older than we thought..
it doesn't seem like its that big of a problem.., ?

Bless his soul man he made me day with that smile :) love it ❤

[MadnanTheArcher]

Just had a bit of a realization.. Since a black hole has enough gravity to essentially trap light, at a certain distance it also bends light and turns it 180 degrees back where it came from, so by having a telescope with a good enough resolution looking towards a black hole at the right distance, we can LITERALLY look back in time and see history unfold

[MikeOnTheHomestead]

if the Webb is in space, how does it know what direction to look at to see where the big bang occurred? If the universe is expanding, which way is the center or the origin?

[brad]

Maybe our beginnings started in another galaxy and we just happen to be remains that were along for the ride

[Gaby]

Professor Cox, can we see back in the past when you became a fkin' LEGEND !!! :)

[azmanabdula]

Makes you think if it was ever in visible light back that far

[unbalconsurlavallee]

The belief in time result in the stretching of light. Stress light then time apearrs.

[guitardrummer]

I dont see how light that's been stretching for a time/distance of 13 billion years could possible give us any reliable data. Wouldn't it be warped beyond anything recognizable or at the very least a picture forever frozen in time?
