Hey couldn't galaxy's that are so far apart they can't combine with others galaxies but still in a local group that's apart of other local groups that are also far away enough to not combine be a super galaxy if it's possible the only reason I commented this is because we can't see things bigger than gigantic groups of galaxies or better said could a bunch of the biggest Galaxy clusters combine to make monterous structures in the universe and also could those make even bigger structures and so on thank you for reading just wondering pls reply I really want to know

Theoretical astrophysics is a house of cards.

Question: Since we are seeing into the past, toward the beginning of time, how are we seeing so many later stage galaxies and so few early ones?

Will you be the teacher for crash course's university physics course? :3

i want to be a big gassy baby too D:
-
so how is it that we don't actually see dark matter but when it collapses on itself due to gravitational force suddenly we "see" baby galaxies i.e matter that we can see which formed out of dark matter? Is it explained by higgs boson particle? excuse my ignorance :)

That's the same question I ask my self often: At which point exactly is a group of trees a forest? Or how big exactly is the smallest meadow? There is no clear definition of that. A group of 10 trees can be called a small forest or just a bunch of trees. This is the same as asking how many stars does the smallest galaxy have.

This is proof that God isn't real! YAAAAAAAAY!

"Big gassy babies..." LOL!!!

Türkçe çeviri yapan arkadaşa sonsuz teşekkürler !

surely that a galaxy us a clump of stars with a super massive black hole in the middle?

Please add "SUBTITLE". Your video is good but too fast......
-
The answer is simple God

The galaxy in the thumbnail looks like Mexico

Explain the gargantua thing please
-
They came from Big Bangs Lol stupid atheists

There mightve been a delay when this comment is posted because IE has been pretty slow today, but,
First! -
now I'm going to have nightmares about big, gassy babies...
