How long before the expansion of the universe causes our earth to drift away from the sun? The early universe was largely hydrogen with some helium and lithium, and the first stars formed from that helium. Galaxies look stationary, so why do scientists say that they rotate? It's ending is more like the "long, slow expansion". 57. The study of stars' lives and how they are born, live, and die is called "stellar evolution", and involves looking at many types of stars to understand their life cycles. in 2006.
