How Do Scientists Know the Universe is Expanding?

WebWhen we look out into the sky we see a huge number of stars and an equally large number of galaxies. When we observe carefully, we are able to deduce the distance to many of these galaxies and an interesting correlation was noticed. This was first done by Edwin Hubble, so we call it Hubble's law. WebThe expansion of the universe is happening at large-scales. This means that, if you choose two galaxies, they are moving away from each other at a speed proportional to their distance. The space between the Sun and the Earth, for instance, is not expanding. In fact, some galaxies close to us appear blue-shifted due to their peculiar velocities. fishel\u0027s gun works https://bavarianintlprep.com
