Why is space dark if there are so many stars ??
It is known as Olbers' Paradox.
The Universe is expanding
As space stretches, the light from distant stars gets stretched too !!! This is called redshift.
By the time light reaches us, it has turned into infrared or radio waves that our eyes can't see !!!!
Universe is about 13.8 billion years old. Light from distanced stars simply hasn't had enough time to reach us yet !!!
