The 2D MOT apparatus feeds the science chamber with cold atoms. At the center is a glass cell held under vacuum between coils producing magnetic fields. The atoms enter the science chamber through the ...
Free falling: Einstein's equivalence principle holds that the motion of freely-falling bodies (whether apples, oranges, or anything else) is independent of their composition. The Cold Atom Laboratory ...
The weak-equivalence principle is integral to general relativity, so these test results offer yet more support for a core theory of our universe. In 1916, Albert Einstein dared to declare that Isaac ...
Add Yahoo as a preferred source to see more of our stories on Google. For the first time, physicists have measured the tiny quantum shift an object acquires by falling through Earth's gravity — an ...
(Phys.org)—Physicists have performed a test designed to investigate the effects of the expansion of the universe—hoping to answer questions such as "does the expansion of the universe affect ...
Add Yahoo as a preferred source to see more of our stories on Google. Scientists have spotted the first hints that Albert Einstein's formulation of gravity operates in the quantum realm. There is no ...
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 is 10 to 100 times better ...
