WebUsing gravitational lensing to search for the earliest galaxies in the universe. While they’re too faint to be seen directly, closer-by galaxies and clusters sometimes magnify their light, … WebThe Universe appears to be expanding away from a center point, presumably the source of the Big Bang. Scientists and astronomers have calculated that the expansion would slow down with time, due to the mutual gravitational attraction between the galaxies.
