Absence of light is darkness. Is there any other explanations?
The Universe is actually bathed in radiation left over by the Big Bang, and if our eyes can see in microwave, there would be no darkness anywhere. The fact is that our eyes are very limited in terms of the range of wavelengths of electromagnetic radiation that they can detect. So the point I am making is that the absense of light is NOT necessarily “dark”. It’s just that we can’t see all the different kinds of light that’s there. Yes we can measure the speed of light, because it is finite. But there is no such thing as the speed of darkness since, darkness is not actualy a thing, it is merely a state of lacking visible light.
