A photon from the biggest cosmic explosion since the Big Bang appears to have defied Einstein. Scientists may finally know how

A photon, or particle of light, from the biggest cosmic explosion since the Big Bang, nicknamed "the BOAT" (for the brightest of all time), should not have reached Earth. That is, unless it defied rules defined by Einstein. Now scientists may know how it did this, with new research suggesting how the high-energy photon may have survived a journey of more than two billion light-years without being absorbed.The BOAT, a gamma-ray burst officially designated GRB 221009A, was first detected on Oct. 9
