How can one ignore new evidence that Einstein was right, for now!

7.3 Billion Light-Years Later, Einstein’s Theory Prevails
Astronomers said Wednesday that a race halfway across the universe had ended in a virtual tie. And so the champion is still Albert Einstein — for now.
The race was between gamma rays of differing energies and wavelengths spit in a burst from an exploding star when the universe was half its present age. After a journey of 7.3 billion light-years, they all arrived within nine-tenths of a second of one another in a detector on NASA’s Fermi Gamma-Ray Space Telescope, at 8:22 p.m., Eastern time, on May 9.
Astronomers said the gamma-ray race was one of the most stringent tests yet of a bedrock principle of modern physics: Einstein’s proclamation in his 1905 theory of relativity that the speed of light is constant and independent of its color, or energy; its direction; or how you yourself are moving.
“I take it as a confirmation that Einstein is still right,” Peter F. Michelson of Stanford, principal investigator for Fermi’s Large Area Telescope and one of 206 authors of a paper published online Wednesday in the journal Nature, said in an interview.
