Photon Weight Limit Surpassed: How This Discovery Shakes Up Our Universe
Astronomers from Chengdu, China have set a new upper limit for the mass of light, challenging our understanding of the universe. Through the study of pulsing stars in the Milky Way and mysterious radio signals from distant galaxies, researchers have determined that a photon, the smallest unit of light, cannot weigh more than 9.52 × 10^-46 kilograms. The results have major implications for physics and our perception of the cosmos. While photons are commonly believed …
