Cosmology and Philosophy. One hundred years ago, many scientists believed that the universe was infinite and eternal, with no beginning and no end. When Einstein first developed his general theory of relativity, he found that it predicted that the universe should be either expanding or contracting, but not static. He felt so strongly in an eternal and unchanging universe that he modified his equations to eliminate evolution. When Hubble's results became accept, Einstein called the "fix" of his equations "My Greatest Blunder!" Why do you think Einstein, as well as other scientists of his generation, assumed that the universe had no beginning? You might want to think about the nature of evidence and drawing conclusions from it. You might want to think about the role of authority. Or you might want to consider philosophical impacts...or other aspects of the issue.
