Perihelion is the point at which an orbiting body is closest to the sun. The word comes from Greek and literally means around ...

Quantum theory and general relativity have long described the universe with incompatible languages, one speaking in ...

On Earth, knowing the time feels simple. Your phone pings the same second as a GPS satellite and an atomic clock in a lab.

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

110 years ago today, Albert Einstein published his General Theory of Relativity, which redefined the relationship between matter and gravity. Suddenly, our mysterious universe made a little more sense ...

The gravitational wave is a prediction of the general theory of relativity that can be detected by measuring the relative distance between two test masses (TM) along the geodesics. The TM is fixed by ...

Tiny “Ferris wheels” made from light and extremely cold particles could allow researchers to test a facet of Albert Einstein’s theory of relativity on unprecedentedly small scales. Theories of special ...

We’re watching a new trend in semiconductor stocks concerning circular deals. Here’s why we think investors should be keeping an eye on it, though they shouldn’t be particularly worried at this point.

The New Scientist Book Club made a jump backwards through time for our latest read, Alex Foster’s Circular Motion, moving from the millennia-ahead future of Adam Roberts’s Lake of Darkness to a world ...

A research team proposes utilizing numerical relativity, a computational technique for solving Einstein's equations in high-gravity environments, to investigate the universe's origin. The approach ...

ABSTRACT: Dramatic simplification of mathematical apparatus, special relativity’s hyperbolic versus circular versions, some equivalence of SR and Newton’s theories, algebra of relativistic and the ...

Breakthroughs in science often begin with a simple question and years of tireless exploration. From the way tiny molecules slip through microscopic pores to the staggering behavior of matter near ...
