Hershey High School's Theory of Relativity Pathfinder.
This will help me with my physics project.
On this web site you'll see how it talks about relativity. No on was general relativity the first major new theory of gravity but it was the first one since Isaac Newton's more than 250 years earlier. Many of the predictions of general relativity have been quantitatively confirmed by experiment. It also talks about how Einstein and others applied general relativity to the structure and evolution of the universe as a whole.
