Non uniformity of time!

There has not been much of a confirmed shakeup on time since the time of Albert Einstein, including that time speeds by faster at the north pole than the lower latitudes of Earth. It is not the same speed experienced at all points. It is not

uniform.

Recent studies are confirming that time in the cosmos also is not uniform everywhere.

It is calculated in the universe that time in the voids can pass more and quicker due to the fact that there are fewer atoms to slow down time's passing in voids than in the denser bodies. This draws a conclusion that there is no single or uniform distribution of time for the age of the cosmos.

"Because there is hardly any matter in a void, time can progress very differently there, 'voids can be as much as 4 billion years older than clusters of galaxies...

more time will have passed since the big bang in a void. There is no such thing as a single age for our cosmos."'

This irregularity could deign a review of major claims of the Copernican principle. Can the universe look the same from all positions?
