Question : 21 [SSC SO 2006]
To an astronaut sky appears
a) rich blue
b) dark
c) light blue
d) white
Answer »Answer: (b)
Sunlight doesn’t light up space because there is nothing there for it to light up. Light in space travels in straight lines, so we only see sunlight when we look at the sun.
As for the rest of the universe, if we assume an infinite universe, we would expect it to be bright with the light of infinity of stars. This is called Olbers’ paradox.
But the intensity of the light decreases with the square of the distance, and at some point, the stars are too far away and receding too fast for their light to ever reach us. So the actual amount of starlight from very distant stars is negligible.
