Physics is supposed to be predictable. Drop a ball, and gravity pulls it down. Heat water, and it boils. Light travels in straight lines. Yet throughout history, scientists have encountered ...
Physicists have tested the hypothesis that gravitational fluctuations in space-time can destroy quantum superposition and ...
An Einsteinian view of gravity, a curvature in spacetime caused by mass and energy. (ESA/C.Carreau) Quantum mechanics and Einstein's general relativity explain how the Universe works at the tiniest ...
A garage experiment argues that density and buoyancy can explain falling objects without gravity, using rocks, water and ...
Physicists have put a decades-old idea about why the strange rules of quantum mechanics disappear in our everyday world to ...
Scientists have found a new way to create a controlled beam of muonium, an exotic atom containing a heavier cousin of the electron. The advance could allow researchers to test for the first time ...
Here on Earth, gravity is part of everyday life. We can’t live without it, but most people never stop to think about how gravity occurs and how gravity impacts mass on a subatomic level, where it’s ...
A new experiment found that a falling quantum wave behaves just as Einstein’s equivalence principle predicts. The result ...
Physicists have proven a 100-year-old prediction of relativity by showing that Einstein's equivalence principle holds at quantum scales.
There is a glaring gap in our knowledge of the physical world: none of our well-established theories describe gravity’s quantum nature. Yet physicists expect that this quantum nature is essential for ...
For more than a century, quantum mechanics and Albert Einstein’s theory of general relativity have each passed countless tests, but physicists have struggled to reconcile the two. Now, scientists in ...
Everything around us, from atoms and molecules to planets and galaxies, is governed by two extraordinarily successful theories of physics: quantum mechanics and gravity. Quantum mechanics explains the ...
