Explanation:
Detailed explanation-1: -The farther the galaxies are, the faster they’re traveling away. One might expect gravity to slow the galaxies’ motion from one another, but instead they’re speeding up and scientists don’t know why.
Detailed explanation-2: -Galaxies are moving at a constant speed, the ones further away are so because they move faster. Galaxies move faster away the further they are from each other, because there is more matter between them that expands.
Detailed explanation-3: -Using the ratios he observed, Hubble determined that the farther the galaxy, the greater the red shift. In other words, the greater the distance between a galaxy and the earth, the faster that galaxy was moving away from us.
