The Standard Resolution
The standard resolution to this paradox invokes the finite age of the cosmos and the speed of light. Even if the cosmos is endless and full of stars, one might reason, we can only see the ones that are close enough for there to have been enough time (since the beginning of the Universe) for the light to reach us from there. Anything distant enough from the Earth that the light travel time is more than the age of the Universe is invisible to us.
