Time already behaves strangely in modern physics. It can stretch, slow, and split depending on speed and gravity.

In quantum physics, objects can exist in multiple states at the same time—a phenomenon known as quantum superposition, where ...

Few concepts in physics are as familiar, yet as enigmatic, as time. In Einstein's theory of relativity, time is not absolute: ...

We think of it as rigid, smooth, and unidirectional – the arrow of time flies straight and true, and all we can do is go ...

For more than a century, gravity has been the stubborn outlier in physics, resisting every attempt to be folded neatly into the quantum rules that govern the rest of nature. Now a convergence of bold ...

Physicists at Kyushu University in Japan have outlined a technique that could bring one of the most elusive goals in modern ...

Quantum mechanics has always carried a quiet tension. At its core, the theory allows particles to exist in many states at once, described by a mathematical object called a wavefunction. Yet daily life ...

The cosmological constant has been a problem in physics since Einstein, but new research may show why it takes the value that ...

A long-standing challenge in physics has been to integrate gravity into the Standard Model, which successfully describes the electromagnetic, weak, and strong forces. The difficulty lies in the ...

In quantum physics, objects can exist in multiple states at the same time—a phenomenon known as quantum superposition, where ...

A number of experiments have been proposed to generate and witness gravitational entanglement, but Aziz and Howl’s work suggests that the presence of gravitational entanglement is not a ‘smoking gun’ ...
