Einstein was right: general relativity confirmed.

I don't care what Einstein thinks - I still believe the universe is one giant stroopwafel. From Space.com:

Score one more for Einstein. A new study has confirmed his theory of general relativity works on extremely large scales.

The study was one of the first rigorous tests of this theory of gravity beyond our solar system. The research found that even over vast scales of galaxies and clusters of galaxies, the equations of general relativity predict the way that mass pulls on other mass in the universe.

The new work also helps rule out a competing theory of gravity that seeks to do away with the need for bizarre concepts like dark matter and dark energy that have irked some scientists. This research indicates those pesky ideas may be here to stay.
