The Universe is everything, as far as we know. A galaxy is just a collection of stars. A galaxy is huge - typically about 100,000 light-years across - but the visible Universe contains hundreds of billions of galaxies.
Like our galaxy contains billions of stars, the universe contains billions of galaxies.
The difference is ones dead. Ones young and ones old

Brittle stars crawl and basket stars do not move or crawl.
The Universe is much larger, and contains many solar systems.
Stars are scattered all across our universe but guess what? there are no stars in our solar system besides the sun!
The Universe.
The universe is not black. The universe as a whole is microwave, at a cavity radiation temperature of about 3 K. The space between stars just looks black because you can't see microwave.
