The stars between stars in those new JWST images reminded me of an old paradox about infinite universe. The so called Olbers' paradox or dark night sky paradox is a conflict between the assumption of infinite universe and the darkness of the night sky.
If the universe would be infinite and static there would be infinite amount of stars in it as well. That would mean that every line of sight in the sky would end up in a star making the sky appear bright all the time. The sky not being lit with infinite light all the time is a proof of that the universe is indeed not static.
The paradox is usually attributed to a 19th century amateur astronomer Heinrich Wilhelm Olbers, but the earliest mentions of the concept can be traced all the way back to 6th century when a Greek monk Cosmas Indicopleustes already addressed the problem with the heat resulting from infinite stars.
