The universe doesn’t expand at a speed! 🌌 #astronomy #space #cosmology

Highly recommend checking out the full video linked under my username! I understand how this section can be hard to grasp in isolation haha 🌌

[KyRogers]

We need longer than a minute to grasp and understand wtf you are saying

[Toastfrench]

Good explanation: the galaxies arent moving away from eachother, the space in-between them is getting bigger.

[abodabalo]

That will take a while to sink into my brain

"The universe is under no obligation to make sense to you" - NDT

This pretty much sums it all up

Something that blew my mind is that, if you obtain the value of the hubble constant, dividing 70km/1s/1megaparsec (1 megaparsec=3.086×10^19km) yo get 2.3×10^-18 s^-1. If you take the inverse of that to get units of s, you get 4.4×10^17s. Finally, this seconds are approximately 13.8×10^9 yeras, THE AGE OF THE UNIVERSE!

Just imagine all the laws of physics we DON’T know out in the galaxy or the universe as a whole. We only know what we learned from our solar system and what we can hypothesize from just observing with telescopes

The expansion of space isn't faster than light but the expansion of the universe is.

If we take two points in space, that are a distance away from each other, say two galaxies at the opposite sites of the observable univere, you get distance over time over distance multiplied by distance, so distance over time, which is a speed faster than the speed of light.

[nikhilkiran]

The point is it expands so fast that light from point A may never reach point B. Hence, in sense, its "faster" than light.

[Yorale]

You make this understandable, that's so cool

[ClappOnUpp]

d/t/d= d^2/t
Fraction rule is a/b/c=ac/b

1/t would have to be..
(d/t)/d=1/t
Because (a/b)/c=a/bc

[JadianRadiator]

Yeah, the expansion of the universe doesn't have a speed.
However the expansion still means stuff is comparatively separating at a speed.

[wreck-loose]

Clusters are not physically 'moving' away from each other, the space between them simply increases.
Galaxies on either side of the universe will observe the galaxies between them moving in opposite directions

Thank you for simplifying things to a person like me. I've always loved the cosmos but I can't comprehend all those things without someone explaining it to me in a much more simple term. Thank you, truly.

[mldnighttruffle]

I’m literally the guy Evan is talking to in every video. “HUH??”😂

[owlighting]

You're the first one who in my opinion explained it very clearly. It is one thing to understand something, and another to be able to explain it in an understandable and easy way.

[bili]

All this complexity is because of the fact that we don’t talk about an « object that move in space » but we talk about « space doing something everywhere »

[SugarPopi]

Its easier to think of it as: everything expending slower than light but to all directions, so from perspective it looks like things are getting further from you faster than light, but its cuz you're getting away from them too. And if you're wandering how can everything expend to all directions, its cuz its the actual fabric of space thats expending

[andrewmaderer]

That’s actually a really interesting way of stating it and I wouldn’t have been able to really wrap my mind around it without that analogy at the end. Another awesome video man!
