Physicists put in place groundwork for accurately testing Einstein’s equivalence principle. A team of scientists from Germany has succeeded in creating a Bose-Einstein condensate for the first time in space on board a research rocket. On January 23, 2017 at 3:30 a.m. Central European Time, the MAIUS-1 mission was launched into space from the Esrange Space Center in Sweden. After a detailed analysis, the results have been published recently in the journal Nature...

A new way to test one of the basic principles underlying Einstein’s theory of General Relativity using brief blasts of rare radio signals from space called Fast Radio Bursts (FRB) is 10-100X better than previous testing methods that used gamma-ray bursts. The new method is considered to be a significant tribute to Einstein on the 100th anniversary of his first formulation of the Equivalence Principle, which is a key component of Einstein’s theory of General Relativity...
