Time travel has shifted from pure fantasy to a serious, if highly constrained, topic in modern physics. The equations that ...

In the gloomy days of January, time seems to drag. According to the Einstein theory of relativity, it actually does—in a minute amount that means little to anyone except a scientist. During its annual ...

Using Einstein's theory of general relativity, physicists found that clocks on the moon would run 56 microseconds faster than clocks on Earth. That finding will help future lunar missions navigate.

Einstein's theory of general relativity has passed its toughest test with flying colors, a new study reports. General relativity, which Einstein proposed in 1916, holds that gravity is a consequence ...

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 ...

The big thinkers at Aperture explain relativity and how it warps the fabric of spacetime. Experts warn the internet will go down in a big way — and you'd better be ready ...

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 ...

As new and powerful telescopes gather fresh data about the universe, they reveal the limits of older theories like Einstein's relativity. When you purchase through links on our site, we may earn an ...

A splashy California-based launch company named Relativity Space shared a photo of sleek-looking rocket hardware on its social media channels last week. The image featured an impressively large ...

The former Google chief executive is taking a controlling interest in Relativity Space, which aims to build low-cost, reusable rockets to compete against Elon Musk’s SpaceX and to reach Mars. Eric ...
