Racing across the Universe for the last 7.3-billion-years, two highly charged particles have arrived at Nasa's Fermi Gamma-ray Space Telescope within a second of one another. Excited scientists believe this could be evidence of Einstein's space-time theory.
The photons were launched on their marathon during a short gamma-ray burst, an outpouring of radiation likely generated by the collision of two neutron stars, the densest known objects in the Universe.
One of the photons possessed a million times more energy that the other but they arrived at almost the same time.
In Einstein's vision of a unified space-time all forms of electromagnetic radiation, from gamma rays through to X-rays, are thought to travel through the vacuum of space at the same speed, no matter how much energy they have.
But in some new theories of gravity, space-time is considered to have a 'shifting, frothy structure' when viewed at a scale trillions of times smaller than an electron.
