Yes, the whole universe is expanding rapidly and so are the galaxies within it.
It means that the light from galaxies is losing energy. The only reasonable explanation for this is the cosmoligical redshift - that is, that the Universe is expanding.
because the universe is expanding.
Edwin Hubble was responsible for the concept of the universe expanding.
Yes ...why.. well there is a theory that once the universe was as small as a match's red head? i don't know what it's called what ever...so when that bead explodes and it expands. and scientists believe that it keeps expanding. Another question you should ask your self is if that the universe was that small what was around it? answer it cause i wanna know and hope this helps!
