Fermi Telescope Caps First Year With Glimpse of Space-Time
January 10, 2013
In this illustration, one photon (purple) carries a million times the energy of another (yellow). Some theorists predict travel delays for higher-energy photons, which interact more strongly with the proposed frothy nature of space-time. Yet Fermi data on two photons from a gamma-ray burst fail to show this effect, eliminating some approaches to a new theory of gravity. The animation link below shows the delay scientists had expected to observe. Credit: NASA/Sonoma State University/Aurore Simonnet
