Hubble and the Accelerating Universe. Edwin Hubble was a young scientist, having just returned from WW1, when he noticed that every star and galaxy he observed appeared to be moving away from us. Through red shift, his measurement and observations were confirmed, every observable source of light in the universe was accelerating away from us, as space time continued to expand, we call the force leading to this acceleration "Dark Energy". Hubble had unknowingly made one of the biggest discoveries of his lifetime in astrophysics and cosmology. To this day, we do not know why the universe is expanding, and it will continue to be one of the biggest mysteries in the universe for many more generations of scientist and researchers
