As of 2018 it is thought that the expansion of the universe is accelerating. The farther away, the faster this acceleration such that at some distance the rate of expansion of the universe will be equal to the speed of light. And anything beyond this distance will be expanding at a velocity greater than the speed of light (it is space itself that is traveling faster than the speed of light rather than the objects in it). The light from these objects that are traveling faster than the speed of light will never be able to reach us because the light cannot travel fast enough to overcome the expansion of the universe. Thus everything that exists beyond a certain distance will never again be visible to us. In addition, because the expansion of the universe continues to accelerate, objects closer to us will one day be expanding away at a rate greater than the speed of light. So at some point everything in the sky will become dark as all of the stars and galaxies in the sky will eventually be expanding away faster than the speed of light; their light will never be able to reach us... Let us take it a step further and suggest that at some point the universe in our immediate vacinity will be expanding faster than the speed of light. Will I be able to see the person sitting across the table from me? Will I be able to see my own hand stretched out in front of my face? will my hand still exist?...
