Physicists have proven a 100-year-old prediction of relativity by showing that Einstein's equivalence principle holds at ...

A new theory proposed by researchers at the Stevens Institute of Technology, Colorado State University, and the National Institute of Standards and Technology (NIST) shows that time can exist in a ...

Physicists have directly observed a long-predicted quantum effect of gravity, putting one of Einstein’s foundational ideas to ...

Researchers from the Austrian Academy of Sciences and the University of Vienna have demonstrated a precise method for reversing time in a quantum system, achieving an average fidelity of more than 95% ...

For decades, quantum physics and general relativity have stood as two powerful but separate theories. Quantum physics explains the behavior of tiny particles like atoms and photons. General relativity ...

Within our comfortable world of causality we expect that reactions always follow an action and not vice versa. This why the recent chatter in the media about researchers having discovered ‘negative ...

The original version of this story appeared in Quanta Magazine. In the fall of 2022, a Princeton University graduate student named Carolina Figueiredo stumbled onto a massive coincidence. She ...

One hundred years ago on a quiet, rocky island, German physicist Werner Heisenberg helped set in motion a series of scientific developments that would touch nearly all of physics. There, Heisenberg ...

So far, quantum computers have been held back by their extreme sensitivity to errors and external disturbances. The longer a ...
