The youngest galaxy observed thus far is estimated to be 400 million years after the Big Bang. It seems to me that it would have started forming before that observed time frame, maybe by a couple hundred million years. In thinking about this, a several questions popped up.
1. How long after the Big Bang were the rest of the Billions upon Billion galaxies that we have today came into form?
2. Are new galaxy being formed today?
3. Has new galaxy formation ran it's course?
4. As galaxies crash into each other, or die, it seems to me that there are less in number today than in the past?
