A high-performance computing researcher has predicted a physical effect that would help physicists and astronomers provide fresh evidence of the correctness of Einstein’s general theory of relativity. 
So. More proof of Einstein’s general theory of relativity.
So. Have we believed in the theory all this time with not enough proof?
Proof is not proof.
Theories are not “true”.
It is like the science you once knew.
But somehow less… magical.
Depends on how you see it…
