Somewhere between the microscopic realm of elementary particles and the macroscopic world of human beings, something strange ...

Excerpt from the full video "How the Entire Quantum Universe is Inside an Atom." A simple home experiment demonstrating how ...

A new experiment found that a falling quantum wave behaves just as Einstein’s equivalence principle predicts. The result ...

Superfluid helium has produced a narrow muonium beam, opening a path to test whether exotic particles fall like ordinary matter.

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 ...

Does gravity act equally on all particles in the universe, or are there differences between ordinary and exotic matter?

Is gravity a quantum phenomenon? That has been one of the big outstanding questions in physics for decades. Together with colleagues from the UK, Anupam Mazumdar, a physicist from the University of ...

Physicists have directly linked quantum mechanics and Einstein's gravity theory. An experiment used ultracold atoms in ...

Just over a week ago, European physicists announced they had measured the strength of gravity on the smallest scale ever. In a clever tabletop experiment, researchers at Leiden University in the ...

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 ...

A NASA experiment examined the growth of fern spores in a zero-gravity environment. The spores showcased continued ...
