What is the “cosmic light horizon”?
A)   It is the distance beyond which we cannot see because light cannot have traveled any farther in the finite age of the universe.
B)   It is the distance beyond which we cannot see because no stars or galaxies had yet formed at those distances (because we see back in time as we look out into space).
C)   It is the distance beyond which our own radio and television signals cannot have traveled through the universe.
D)   It is the distance beyond which we cannot see because of absorbing matter in the universe.
