Scientists have determined a way to measure gravity on microscopic levels, perhaps bringing them closer to forming a theory of "quantum gravity" and to solving some major cosmic mysteries. Quantum ...

Quantum Gravity and General Relativity represent two foundational yet traditionally disparate pillars of modern physics. General Relativity, Einstein’s seminal theory, elegantly encapsulates ...

Engineers have found a way to shepherd microrobots with no wires, no radios, and no onboard computers. Instead, they steer them with light patterns designed using the same math physicists use to ...

Newton's theory of gravity posited instantaneous gravitational attraction, successfully predicting planetary orbits. Einstein's special relativity challenged this, necessitating the development of ...

An international team of astronomers has conducted a new test of Albert Einstein's famous theory of general relativity (GR), finding that it works even in extreme gravitational environments, according ...

Scientists are trying to figure out to what extent a new theory of quantum gravity will reproduce general relativity. Scientists at Texas A&M University in the US explore this question in a paper ...

Thanks to Einstein’s relativity, time flows differently on Mars than on Earth. NIST scientists have now nailed down the ...

First of all, the prevailing quantum theory, quantum field theory, is fully relativistic from the onset. Relativity is “built into” the theory, so to speak. And it’s the only quantum theory that is ...

When you purchase through links on our site, we may earn an affiliate commission. Here’s how it works. Albert Einstein's theory of general relativity has held up pretty well after a century out in the ...

In 1915, Albert Einstein put forth a new theory of gravity: General Relativity. Instead of every mass in the Universe instantly reaching across to every other mass and exerting an attractive force, ...
