Movie   ID   Roles   Title
Animation showing how the photons may have acted if the structure of space-time was foamy. However, Fermi data has shown that that effect does not exist.   10489 Scientist
  Gamma-ray Burst Photon Delay as Expected by Quantum Gravity
Galactic north pole map of blazars observed by Fermi, without overlays.   10505 Scientist
  Blazars at Galactic North Pole, Seen in Fermi's First Year of Observations
Alternate sequence of dissolves showing the improvement in the Fermi all-sky map, from 1 week to 1 year.   10508 Scientist
  Fermi All-Sky First Year Progress
In its first year of operations, NASA’s Fermi Gamma-ray Space Telescope has mapped the entire sky with unprecedented resolution and sensitivity in gamma-rays, the highest-energy form of light. On May 10, 2009 a pair of gamma-ray photons reached Fermi only 900 milliseconds apart after traveling for 7 billion years. Fermi’s 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.<p><p><p>For complete transcript, click <a href=   10510 Interviewee
