Quantum physics is quietly rewriting the rulebook for how far and how fast humanity might travel beyond Earth. A cluster of ...

Their work introduces a new concept called q-desics, short for quantum-corrected paths through space–time. These paths generalize the familiar trajectories predicted by Einstein’s general theory of ...

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 ...

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 ...

As physicists search for a theory of quantum gravity, new results show that classical gravity can still interact with quantum fields to allow matter to become entangled. When you purchase through ...

A team of physicists has reimagined one of science’s most iconic experiments—but in the dimension of time. Researchers at Imperial College London have taken the classic double-slit test and turned it ...

A team of physicists has created a cloud of ultracold atoms that stubbornly resists the most basic rule of everyday ...

Albert Einstein’s theory of gravity, general relativity, is famously incomplete. As proven by physics Nobel laureate Roger Penrose, when matter collapses under its own gravitational pull, the result ...

Does the universe notice that we're paying attention to a quantum experiment? The answer goes against everything we thought we knew.

The experimental sensor could be groundbreaking. When you purchase through links on our site, we may earn an affiliate commission. Here’s how it works. A US military space-plane, the X-37B orbital ...

Every year, Santa Claus races around the globe in a matter of hours to bring presents to children all over the world.

In the fall of 2022, a Princeton University graduate student named Carolina Figueiredo stumbled onto a massive coincidence. She calculated that collisions involving three different types of subatomic ...
