News, Einstein predictions confirmed by NASA probe. (Earth, Sun, theory)

[JD59]

A NASA probe circling the Earth has found evidence that confirms two key predictions based on Albert Einstein's theory of general relativity.

The results from the Gravity Probe B mission show that the Earth's mass does warp space and time, which are interlinked, NASA announced Wednesday.

I read about that. It's another confirmation that objects with mass create a warp in spacetime.

It had also confirmed decades earlier by experiments conducted by Irwin Shapiro who noted a difference in the amount of time (a spike) with a signal passing near the Sun. The signal was 200 microseconds longer than if spacetime around the Sun was not curved. And of course, there were the atomic clock experiments, and the observation of gravitational lensing.
