Paradoxically Olbers paradox

 


This is a typical photo of an Egyptian temple representation of the night sky. 

Whats so strange about it?


Given what I have seen in our recent visits to Egyptian temples and their ability to undertake detailed observations and then represent them in fine carvings and story telling, I find it strange in the extreme that the best  they could do with representation of the night sky is effectively a blanket of starfish like stars.

No constellations, no 'brighter' stars, no Moon? It's effectively a night sky completely full of stars. Wherever you look there is a star. Exactly what Olbers paradox is all about - why is the night sky dark - if, in an infinite universe filled with stars, why would you not see a star wherever you looked? Essentially the night sky would then be bright!

Of course we now have an explanation for the night sky being dark - see Wikipedia Olbers paradox, for a start. Short answer is a finite universe and red shifted star light because it is also expanding. Well at least thats what we think at the moment.

So maybe those 👽 weren't so clever after all.....or maybe they know something we don't!

Again, I thought that was going to be it on the Egyptian front, but looking at these night sky depictions has raised another issue.....
