Remarkable. 50 million light-years away and still able to have a noticeable gravitational impact on our cluster of galaxies? 2000 galaxies of which 1993 move incoherently?

I've seen one estimate that there could be up to 2 trillion galaxies in the universe. I wonder if anyone has tried to calculate how many stars that might be--given that galaxies vary greatly in size.

It is mind boggling just trying to comprehend the size of our own galaxy.
