Physicists found that clocks on Mars will tick 477 microseconds (millionths of a second) faster than on Earth per day, on ...

Gravity and motion make time pass faster on Mars than Earth, reshaping navigation, communication, and future crewed missions.

Ask someone on Earth for the time and they can give you an exact answer, thanks to our planet's intricate timekeeping system, built with atomic clocks, GPS satellites and high-speed telecommunications ...

Scientists have demonstrated the existence of gravity between antimatter and Earth, reaffirming Albert Einstein’s General Theory of Relativity. It is thought that Isaac Newton's historic work on ...

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 ...

For decades, quantum physics and general relativity have stood as two powerful but separate theories. Quantum physics explains the behavior of tiny particles like atoms and photons. General relativity ...

A substance called antimatter is at the heart of one of the greatest mysteries of the universe. We know that every particle has an antimatter companion that is virtually identical to itself, but with ...

When I was five years old, my family moved into a 1930s semi-detached house with a long strip of garden. At the end of the garden was a miniature orchard of eight apple trees the previous owners had ...

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 reconciliation of general relativity and quantum mechanics is one of the biggest challenges in science, one that continues to elude us. Now, a new study by Anjun Chu and colleagues has examined ...
