Space+of+the+Universe

Space of the Universe The space of the Universe composed of all the invisible and visible matter and energy. The universe began long ago, but we're not certain.While the universe is believed to be flat, it remains undecided whether or not it is infinite.

Recently scientists discover that, our universe is expanding for some reason.The observations of redshift helped us to make this discovery. Redshift refers to the process whereby all visible light bends towards the red end of the spectrum. Since we cannot observe space beyond the limitations of light it is uncertain whether the size of th ﻿ e universe is finite or not. By: Hoang le
