Quasicrystals are orderly structures that never repeat. Scientists just showed they can exist in space and time.

Some say we’ve entered a new age of AI-enabled scientific discovery. But human insight and creativity still can’t be ...

Energy efficiency in physics is not measured the way most people think about it. Instead of asking how much heat a process ...

It feels so obvious that time moves forward that questioning it can seem almost pointless.

This is an example of time dilation, a consequence of the idea that time and space are not absolute - meaning all observers do not always measure these quantities as the same. In everyday life we use ...

Physicists artificially slowed down time to reveal the bizarre Terrell-Penrose effect, a consequence of special relativity. This image from the experiment shows a sphere seemingly moving at 99.9 ...

[Translated by Dr. Robert W. Lawson.] THERE is something attractive in presenting the evolution of a sequence of ideas in as brief a form as possible, and yet with a completeness sufficient to ...

The big bang wasn’t the start of everything, but it has been impossible to see what came before. Now a new kind of cosmology is lifting the veil on the beginning of time ...

For those who watch gravitational waves roll in from the universe, GW250114 is a big one. It's the clearest gravitational wave signal from a binary black hole merger to date, and it gives researchers ...

A record-breaking gravitational wave signal let scientists "listen" to a distant black hole merger and put Einstein's gravity to its toughest test yet.

Exploring the quantum nature of gravity requires systems that balance quantum control and gravitational interaction, most plausibly within the microgram-to-milligram mass range. Here, the authors ...

The second reason is simple: location, location, location! The millisecond pulsar appears to be near Sagittarius A*, the supermassive black hole at the center of our galaxy. Sagittarius A* weighs ...
