Scientists challenge General Relativity. And Mr. Einstein wins
again. Two tests use cosmic laboratories to question if the laws
of physics are universal. Physicists assume that the laws they
discover on Earth hold true throughout the universe and
throughout all time. Their faith is only as good as the facts
that support it. That support now is a little stronger.Skip to

a mathematical constant that’s fundamental to our understanding
of particle physics remains the same on Earth today as it did
half way across the universe and billions of years ago. And an
unusual object 1,700 light-years away has verified Einstein’s
general relativity theory of gravity with a type of measurement
never made before. Atoms are made up partly of protons and
electrons. The ratio of a proton’s mass to that of an electron
is one of the bedrock constants underpinning our standard theory
of particle physics. If this – or any other fundamental constant
– varied from place
