Galaxies are formed when the gravitational pull comes together pushing stars in. Since black holes were extremely commmon at the birth of the universe, many galaxies own one, such as ours, the Milky Way. Galaxies such as the Sombrero and Andromeda have similar Holes. These holes are supermassive holes, giant gravity balls.
Because that is what galaxies are "made" up of.
the universe is made up of galaxies
Yes. Our local group of galaxies is made up of 3 larger galaxies (milky-way, Andromeda and M33) and several smaller or dwarf galaxies.
Chuck norris sneezed
well the universe is endless, but the universe is made up of many galaxies, and galaxies are made of planets and stars and dust etc.
it is mostly made of space
Galaxies are made partly of stars, which produce light. So, in that sense, yes.
no specific reason. they formed on their own.
We do not know. We have not made contact with any aliens.
No, the stars actually make the planets.
Much more than that, actually. The number of galaxies in the OBSERVABLE Universe is at least 1011.
Galaxies were made by God from the beginning of time.Answer:The scientific opinion is that galaxies result from the gravitational attraction of matter into stars and the interactions of the stars to form clusters of swirling stars.. The matter originated in the "Big Bang" that was the beginning of the Universe some 15 billion years ago.
