• Resumen

  • The first simultaneous detection of gravitational waves and light from a cosmic collision has left a few alternatives to dark matter and dark energy dead in its wake. These theories supposed that gravitational waves--ripples in the fabric of space-time--travel slower or even faster than the speed of light. But observations have proved otherwise. A recent neutron star merger created gravitational waves seen by the LIGO detectors, a gamma-ray burst seen by NASA's Fermi satellite, and yet more electromagnetic waves caught by other telescopes.
