Space is empty. On Earth you see a bright blue sky when the Sun is up because light from the sun is scattered by the atmosphere. In the absence of atmosphere, the sky around the Sun remains black in space because there is nothing to scatter the light. You only see the light directly from the Sun.

The easiest way to understand is look at a searchlight. Some dust particles reflect, but it seems to abruptly end if it does not find an object to reflect the beam.

You cannot see light rays side on. You can only see light when looking at the source or reflections off something in the light path that sends a bit of light your way.

They do not produce enough light. Imagine having a disconnected Helicopter spot light in a hall. Would brighten up the whole room because the light is reflecting of walls etc. Now take that light into a desert....

the main reason is vastness of the universe. sun is a small peck in the universe.
other stars are there but vast spaces between celestial bodies means light doesnot reach everyewhere.
plus there are shadows of heavenly bodies to add to the darkness.

Simple answer is because it is (essentially) empty. There is nothing for the light to reflect off.
