Andromeda galaxy

wow there is a lot beyond our imaginations man i hope some how u manage to acheive hyperspcae technology i wanna c wht we discover. something true not like that brazillian scientist talking about "BROTHERS FROM STAR NATION ARE GOING TO VISIT THE EARTH" yea sure and why would they happen to tell him about it freakin making up fake rumors.

wow well thats really amazing man. If thats possible than why are planets in galaxies i mean why wont there be all the stars in the sky without living in the galaxy i don't if this makes sense but can there be a black hole in side of a galaxy like neat some planets or some thing like that

Well planets form from the accreation disks around stars, and stars
are formed from massive amounts of gasses compressing and causing
heat to such a point the a fusion reaction occurs, so there won't be
alot of planets by themselves outside of the galaxy.

The reason stars, and there accompanying planets exist primarily in
galaxies, is because galaxies are basically gigantic clusters of material,
so the stars and planets form inside the galaxy.

Yes, black holes can exist in galaxies, in fact our own galaxy has two supermassive black holes at its the center, and may have many
smaller ones elsewhere as well.

It's suspected that the majority of galaxies have atleast one blackhole
of some sort in them, in fact until recently I'd been taught that most
galaxies had atleast one supermassive black hole at there center,
but I read an article that says that may not be the case.
