Time feels familiar. It marks every moment of daily life, from the ticking of a wall clock to the changing numbers on a ...

Using one of the world's most precise atomic clocks, physicists have shown that time runs a tiny bit slower if you change your height above the Earth's surface by a minuscule 0.008 inch (0.2 ...

Scientists have observed “bending” atoms using a crystal grating—an experiment once believed impossible at the high energies required. The authors of a new, non-peer reviewed study detail how the a ...

The atomic nucleus is made up of protons and neutrons, particles that exist through the interaction of quarks bonded by gluons. It would seem, therefore, that it should not be difficult to reproduce ...

A new experiment involving a network of entangled atomic clocks could finally help us test how quantum mechanics fits with general relativity. Quantum mechanics is our best understanding of the ...

Why do certain surfaces behave very differently from what theoretical calculations suggest? Scientists long assumed that the ...

Atomic clocks. They almost sound like something out of science fiction, or an experiment confined to some elite physics lab, but in reality, they’ve been around since the 1950s in one form or another.
