James Webb Space Telescope confirms Einstein zig-zag phenomenon, offering new insights into cosmology

Astronomers have observed the first confirmed instance of the “Einstein zig-zag,” a phenomenon where light from a distant quasar bends in a zig-zag pattern after passing through two regions of warped space-time. This discovery, made using data from the James Webb Space Telescope, could help resolve cosmological puzzles like the Hubble tension and provide insights into the universe’s expansion.
