Shouldn't the night sky really be white instead of black? Is it because the big bang gives a cutoff to the light hitting or eyes from deep space?

The dust caused by the "Big Bang" is believed to be one cause.

i have never thought about that before but that is very weird. perhaps all the other stars not created by the big bang which would otherwise make the night sky white are so close that since they have died off there light has rather 'passed us by', but id dont know, perhaps there were no stars before the big bang, or maybe photons have a certain chance of popping out of existance over a given period of time that if a star is far enough away the number of photons reacing us from it will number to few to matter. Orrr.... perhaps everything is just so far away from our sector of the universe that the tiny number of photons hitting our puny planet from that far away is too small to matter at all.
I really havent got a clue

The resolution of Olbers' paradox comes by recognizing that the
Universe is not infinitely old and is expanding. The latter effect
reduces the accumulated energy radiated by distant stars. Either one of these effects acting alone would solve Olbers' Paradox, but they both act at once.

Why should the night sky be white? The night sky is absent of color giving us the illusion of black. It's just clear and absent of color!

There are not many stars. Even there are, some of their light has not reached us yet. So the darkness still is more then the light from the stars. (I don't know wat u mean by light from deep space, I assume it is stars!)
