Besides quantum theory, general relativity is one of two pillars of ... happened in the very earliest instants of the big bang, for example, when the universe was very small and gravity was ...

A new study in Physical Review Letters has used atomic clocks to study relativistic effects in interacting quantum systems.

If gravity arises from entropy, scientists could unite Einstein's general relativity with the quantum realm while shedding ...

Click or tap on the labels below to discover each physicist's example of why general relativity continues to help explain the Universe around us. Dr Aravind Vijayaraghavan reveals how the second ...

Albert Einstein's theory of general relativity—which explains gravity ... The space-time distortions around objects—like, for example, planets or stars—sit in their own little "gravitational ...

After thinking about the problems for 10 years, he published the general theory of relativity. In it, he suggested that gravity is not a force, as Newton had believed, but the result of a ...

For example, the paths taken by planets around the Sun follow geodesics and appear as elliptical orbits. Einstein published a ...

If gravity arises from entropy, scientists could unite Einstein's general relativity with the quantum realm while shedding light on dark matter and dark energy. A new recipe for gravity could help ...
