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 Animator
  Gamma-ray Burst Photon Delay as Expected by Quantum Gravity
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 Animator
  Einstein's Cosmic Speed Limit
This all-sky movie shows Fermi LAT counts of gamma rays with energies greater than 300 million electron volts from August 4 to October 30, 2008. Brighter colors indicate brighter gamma-ray sources. The circles show the northern (left) and southern galactic sky. Their edges lie along the plane of our galaxy, the Milky Way.   10407 Animator
  Fermi All-sky Movie Shows Flaring, Fading Blazars
As the star explodes, the narrow beam (white) of gamma rays is emitted first, followed by the wider beam (purple).   10369 Animator
  Naked-Eye Gamma-ray Burst Model for GRB 080319B
The pulsar's radio beams (green) never intersect Earth, but its pulsed gamma rays (magenta) do.   10361 Animator
  Pulsars Emit Gamma-rays from Equator
