    Default While in outer space, space should be bright if there is an infinite...



    ...number of stars. Where does the light go? Seems while in outer space, space should be a sheet of white with all the stars' light blanketing the background. Pictures of our sun is bright but dims as the spacecrafts are further away. The light goes where?

    go in a dark alley and shine your flashlight... see how far it actually lights up the alley. Not very far. But someone all the way at the other end will still be able to see the source of the light (flashlight) even thought the alley is still dark. same concept in space. we see the source of the light but the light itself doesn't illuminate too much of its surroundings.

    However, the Universe has finite age. So the light from stars an infinite distance away hasn't had time to reach us.

    And, the Universe is expanding. If you get far enough away, the light will never reach us. Never. The Universe is expanding faster than the light can travel.

    The Steady State model of the Universe said that the Universe was infinitely old, and infinitely large. And it predicted the bright Universe, which isn't what we observe. It wasn't the only problem with the model.
