The Secrets Of The Theory of General Relativity In An Alphabetic Primer

Albert Einstein’s theory of general relativity is beautiful, elegant, and a golden standard of, “This is what complex physics looks like.” To celebrate the centennial of its publication, the Perimeter Institute put together an alphabetic primer of lessons and trivia to bring you up to speed. » 5/24/15 4:08pm 5/24/15 4:08pm

Why can't Einstein and Quantum Mechanics get along?

Despite our successes at describing the inner workings of the universe (Higgs, anyone?), there are still some gaping holes in our knowledge. Where's our Grand Unified Theory or our Theory of Everything? And why is Einstein's General Relativity still at odds with Quantum Mechanics? Why should we want to unify them… » 8/09/13 12:24pm 8/09/13 12:24pm

How The Shapiro Time Delay Effect Proves Einstein's Theory of Relativity

There are a couple of reasons why people react with puzzlement to ideas like General Relativity. The idea of "spacetime" is difficult enough to picture, without talk about the idea that mass distorts it the way a bowling ball distorts a trampoline. (Note to self: Promote trampoline bowling as the world's new most… » 2/14/13 12:20pm 2/14/13 12:20pm

How NASA might build its very first warp drive

A few months ago, physicist Harold White stunned the aeronautics world when he announced that he and his team at NASA had begun work on the development of a faster-than-light warp drive. His proposed design, an ingenious re-imagining of an Alcubierre Drive, may eventually result in an engine that can transport a… » 11/26/12 10:13am 11/26/12 10:13am
