On May 10, 2009 a pair of gamma-ray photons reached Fermi only 900 milliseconds apart after traveling for 7 billion years. Fermis measurement gives us rare experimental evidence that space-time is smooth as Einstein predicted, and has shut the door on several approaches to gravity where space-time is foamy enough to interfere strongly with light.<br /> arvana (http://arvana.videosift.com)http://spacy.videosift.com/video/NASA-s-Fermi-Gamma-ray-Space-Telescope http://spacy.videosift.com/video/NASA-s-Fermi-Gamma-ray-Space-Telescope Fri, 06 Nov 2009 09:50:22 -0800 http://spacy.videosift.com/video/Secrets-of-Google-Mars-and-Google-Moon <img src="http://static1.videosift.com/thumbs/s/ec/Secrets_of_Google_Mars_and_Google_Moon.jpg" /><br />(8 votes - 0 comments - 228 views)<br /><br /> arvana (http://arvana.videosift.com)http://spacy.videosift.com/video/Secrets-of-Google-Mars-and-Google-Moon http://spacy.videosift.com/video/Secrets-of-Google-Mars-and-Google-Moon Thu, 05 Nov 2009 19:22:15 -0800
