Yes, the densest clouds of gas in the early universe played a significant role in the formation of elliptical galaxies. As these clouds collapsed under their own gravity, they formed stars and eventually merged with other gas clouds, leading to the creation of larger structures. Over time, the interactions and mergers of these stellar systems contributed to the formation of elliptical galaxies, characterized by their smooth, featureless light profiles and older star populations. Thus, the early dense gas clouds were crucial in shaping the evolution of galaxies in the universe.
They dont become larger they become farther apart from other galaxies
Irregular galaxies are believed to have been spiral or elliptical galaxies in the past, which have been distored through gravitational pull of neighboring galaxies.
The " Big Bang "
Mainly that the Universe is expanding. Analyzing far-away galaxies, it has recently become clear that the expansion is accelerating - the Universe is now expanding faster than a few billion years ago.
Oh, what a lovely question! In the vast observable universe, scientists estimate that there are about 100-200 billion galaxies for us to see. Just imagine all those galaxies out there, putting on a cosmic masterpiece for us to admire. How delightful!

In fact, most galaxies are moving away from all the other galaxies in the universe. Think in terms of expansion. There is no clearly identifiable central spot from which everything emanated, but the galaxies are clearly expanding away from one another. There are occasional collisions of galaxies; we will collide with Andromeda at some point perhaps millions of years from now. This is because there are clusters of galaxies which seem to clump together, orbit around each other and otherwise interact.
Galaxies are a whole lot bigger than planets. And astronomical pictures (x-rays, visible light, etc,) don't reveal much about individual stars, much less planets, within them. Astronomers have become very good at figuring out quite a bit about the Universe from pretty scant data.
That would be a sign that the Universe is contracting, instead of expanding as it currently is.That would be a sign that the Universe is contracting, instead of expanding as it currently is.That would be a sign that the Universe is contracting, instead of expanding as it currently is.That would be a sign that the Universe is contracting, instead of expanding as it currently is.
People work day and night pursuing their goal because they are passionate about it. Sometimes there can be personal incidents that can give you a goal that you would have never thought of. To become an astronomer is difficult but not impossible to tirelessly strive toward your goal until you achieve it.
