Right, the difference is basically size. First comes earth, the Galaxy were in is The Milky Way (it has a fancy name I'm sure but i have no idea what it is). The univeres is a big group of Galaxys, even bigger. Then finally Space is everything, well Outer Space is, it is everything including the Universe, and anything beyond. Biggest.
simply,the difference is that earth is a planet in the solar system and the universe is the entire infinite space containing the solar system,stars, asteroids ,black holes and all that space has to offer.
They thought it was a explosion in the universe so they sent astronauts into space.
The universe
There is no difference between mass anywhere in the universe; it will always be a specific type of bonding between atoms anywhere it goes. However, weight may change due to different gravities on different planets
Space contains multiple Universe which shrinks and expands. Means that Space has multiple BigBang and Universes. (This point of view is based on Scientist's theory on Universe). (Subramanian, J.R.)
If everything exists in space, then where does space exist?"In the space between spaces."as quoted by Dr. Oxley from the movie Indiana Jones......jk :)In the universe. Space exists in the universe.
The universe IS space, plus everything that's in it.
Intergalactic space
Everything in the universe is made up of matter - anything that has a mass and takes up space. Matter is composed of tiny particles called atoms.
The Universe is continuously expanding. The distance between galaxies increases. The amount of space in the Universe increases.
It has a different amount of space between molecules.
There isn't a difference. Astrophysics is the same thing as 'space physics'.
