The light did not fade the way it was supposed to. After blazing into view about a billion light-years from Earth, the supernova known as SN 2024afav settled into something stranger. Its brightness ...

We experience the flow of time because it’s a natural outcome of the basic laws of physics. But we may need to build a whole new model to account for gravity’s influence.

Explore how Albert Einstein transformed our understanding of the universe with groundbreaking theories like relativity and the photoelectric effect. Discover the genius behind E = mc² and the ...

Thanks to Albert Einstein, the US Government wants to establish an official time zone for the Moon. It has less to do with jet lag and more to do with how gravity affects time and can throw a lot of ...

Planets orbiting dead stars known as white dwarfs might be able to remain habitable thanks to general relativity subtly altering their motion. When stars like our sun run out of fuel, they expand and ...

A little while ago, we talked about the concept of timezones and the Moon. It’s a complicated issue, because on Earth, time is all about the Sun and our local relationship with it. The Moon and the ...

New impressions A visualization of a curved space–time “sea” from the general-relativity simulations carried out by the authors.(Courtesy: James Mertens) From the Genesis story in the Old Testament to ...

Timekeeping on the Moon is a trickier problem than you might think. It’s not just the fact that it doesn’t have a diurnal cycle like Earth does — or that one “day” on the Moon is equal to about 29.5 ...

The tiny bots follow patterns of light and "artificial space-time," navigating like craft following the curved space around a ...
