A photon from the biggest cosmic explosion since the Big Bang appears to have defied Einstein. Scientists may finally know how
Astrophysicists are investigating how a high-energy photon from a massive gamma-ray burst managed to reach Earth. Current physics models suggest the particle should have been destroyed by cosmic background radiation during its two-billion-year journey.
Why it matters
Understanding this phenomenon could challenge or refine our fundamental understanding of the laws of physics and the nature of space.
