*
Everything in the universe was concentrated in a single, small point which rapidly expanded into what is now stars, planets, galaxies, matter, and energy.
Two galaxies collided causing an immense explosion as stars crashed into one another.
Parts of the sun were ripped off by massive internal explosions and were thrown into space where they cooled to become other things, like plants, comets, and other galaxies.
All matter emerged from a massive black hole at the center of the universe.
A galaxy contains large groups of stars, planets, gas, and dust. This matter must be held together, or the galaxy will break apart. What is responsible for holding the stars, planets, gas, and dust together in a galaxy?
