Einstein's theory of relativity faces satellite test
Cayenne (AFP) April 26, 2016
Einstein's theory of general relativity is to be put to the test by a newly launched satellite in an experiment that could upend our understanding of physics. The French "Microscope" orbiter will try to poke a hole in one of Einstein's most famous theories, which provides the basis for our modern understanding of gravity. Scientists will use the kit to measure how two different pieces of metal - one titanium and the other a platinum-rhodium alloy - behave in orbit. "In space, it is possibl ... read more
