One of the biggest challenges in modern physics is uniting quantum mechanics and general relativity. A new experiment may ...

According to Einstein's theory of general relativity, gravity results from how mass warps space and time. The greater an object's mass, the stronger its gravitational pull. Scientists have largely ...

For the first time, a mathematical framework proves that Einstein’s theory of general relativity, which explains the relationship between space, time, and gravity, is in alignment with quantum ...

In pure general relativity, with no other modifications or considerations of other physics, they remain black for eternity. Once one forms, it will just hang out there, being a black hole, forever.

Previously, uniting general relativity with quantum physics has meant taking space-time — the three dimensions of space and the one dimension of time, unified as a single 4D entity that is at ...

Space-time isn't expanding into anything because general relativity is what we call a background independent theory. Chanda Prescod-Weinstein sets out to explain what this means ...

Einstein’s general theory of relativity can be summed up in just 12 words: “Space-time tells matter how to move; matter tells space-time how to curve”. But this short description from the ...

Atomic clocks measure Einstein's general relativity at millimeter scale Date: February 16, 2022 Source: National Institute of Standards and Technology (NIST) Summary: Physicists have measured ...

In 1919, a total solar eclipse allowed scientists to confirm Einstein’s theory of general relativity by observing how the sun ...

Test of general relativity by a pair of transportable optical lattice clocks. Nature Photonics, 2020; DOI: 10.1038/s41566-020-0619-8 ...
