Albert Einstein’s theory of special relativity has successfully passed one of its most difficult tests so far. Lorentz Invariance theory states that the laws of physics are the equivalent for observers throughout the universe.To figure this out, scientists examined the data from the High Altitude Water Cherenkov (HAWC) observatory, an arrangement of 300 water tanks constructed on the shoulder of a volcano in Mexico. The study has observed the evidence of photons with energies above 100 teraelectronvolts, about 1 trillion times more powerful than the energy of visible light, flowing from at least four separate astrophysical origins.Scientists believe HAWC data could push those limits out further in the future, providing even more convincing analyses of special relativity.
