Our horizons in the universe are limited by the speed of light
What we can see is determined by a combination of the speed of light and the speed at which the universe is expanding.
THE INVISIBLE UNIVERSE
The light from objects which are now more than 46.1+ billion light years away from us has not reached us yet. And the light that is now emitted from this area will never reach us.
THE VISIBLE UNIVERSE
Our visible universe extends 46.1 billion light years in any direction. Light from the most remote objects in this area was emitted almost 13.8 billion years ago. We will never see the light that the objects emit now.
THE HUBBLE HORIZON
14.5 billion light years away, the Hubble Horizon defines the boundary between galaxies that are moving away from us faster than the speed of light and the ones that are moving more slowly. The light emitted by the latter now will eventually be visible to us.
