There goes the Big Bang theory.
This was published in the Monthly Notices of the Royal Astronomical
Society, presents a theoretical model in which the universe completes a
rotation every 500 billion years. It contradicts the assumed age is 13.8

Bye bye all the relativity crap, black holes, etc.

The theory explain some mysteries unsolved until now, like the

conservation.
