A stunning science site that puts gravity, relativity, quantum physics and string theory all together in an understandable way.

Good add. Strings are great, But I am afraid when it comes to time travel (cause lets face it, nothing else is cooler), wormholes are still the better options. Black and White hole combinations show promise, but then there is still the nasty little event horizon hurdle to get over, and I bet when you reach your first singularity you prolly thinking, "Oh shit, what now". Call me lazy. but personally my time machine is going to be based on photon sail technology.

Wow! You can time travel with photon sails? Ahhhh.. no wait. I understand.. It TAKES time to travel with a photon sail, and LOTS of it!
