The Universe can outrun light without breaking Einstein’s rules

The universe is able to expand at a rate that allows distant galaxies to move away from us faster than the speed of light without violating Einstein's theory of relativity. This phenomenon occurs due to cosmic expansion, which enables galaxies to recede at incredible velocities while still permitting us to observe the ancient light they emitted when they were closer. As a result of accelerating expansion, nearly all galaxies outside the Local Group will eventually be pushed beyond our line of sight. The universe will ultimately appear almost empty, with only a few nearby galaxies remaining visible.
