A few hundred thousand years after the big bang when the first light was able to leap out into space everything in every direction was as bright as the surface of a star. That s because although starlight gets fainter with distance a simple calculation shows the fading is cancelled out by the ever increasing numbers of stars with distance and should therefore leave space ablaze with light.
