How did scientists discover that the universe is expanding? This theory doesn't make much sense to me. What could be pushing the planets and galaxies away from each other?
I just started reading magazines about astronomy such as "Sky and Telescope" and have started reading my physics textbook for high school so I'm not very well educated in physics or information about the universe.
