What we saw in the DESI experiments, and now strengthened by our South Pole Telescope observations, is that dark energy is ...

For over 100 years, two theories have shaped our understanding of the universe: quantum mechanics and Einstein’s general ...

There are new hints that the fabric of space-time may be made of "memory cells" that record the whole history of the universe ...

Albert Einstein's theory of general relativity—which explains gravity as the product of the distortion of space and time—may not be universally applicable. This is the conclusion of physicists ...

However, all attempts to blend general relativity and quantum physics necessarily introduce deviations from Einstein's theory. Therefore, Einstein's gravity cannot be the ultimate theory of gravity.

But general relativity explained gravity to be the result of massive objects bending the fabric of space and time around them. The theory had a problem, however.

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. Close. Advertisement.

(via Minute Physics) This video covers the General theory of Relativity, developed by Albert Einstein, from basic simple levels (it's gravity, curved space) through to the concepts of how curved ...

Listen to the genius himself explain his most well-known formula, E=mc2, from his special theory of relativity. By Sebastian Kettley 15:16, Thu, Feb 4, 2021 | UPDATED: 15:16, Thu, Feb 4, 2021 ...

Einstein’s equations of general relativity were a wellspring from which our current view of the cosmos has flowed. That the theory continues to supply so many rich questions is part of what ...
