For over 100 years, two theories have shaped our understanding of the universe: quantum mechanics and Einstein’s general relativity. One explains the tiny world of particles; the other describes ...

While the ΛCDM model has been a cornerstone of cosmology, it is showing its limitations as researchers seek to explain observations beyond its scope. (CREDIT: ESO/L. Calçada/spaceengine.org) The ...

Scientists have tested gravity across some of the largest structures in the universe and ...

Planets orbiting two stars were expected to be everywhere. Instead, astronomers have found only a few, and new research ...

An international team led by Japanese researchers has made a 3D map of 3000 galaxies 13 billion light years from Earth, and found that Einstein’s general theory of relativity is still valid. Since it ...

Gravity, as most people understand it, is the familiar force that pulls a falling apple toward Earth. But for astronomers and ...

New impressions A visualization of a curved space–time “sea” from the general-relativity simulations carried out by the authors.(Courtesy: James Mertens) From the Genesis story in the Old Testament to ...

What if the technology you use every day depends on a subtle distortion of time itself? The answer lies in a century-old idea ...

Time dilation. Length contraction. The fact that time moves faster at your face than it does at your feet. These are all experimentally verified consequences of the Special Theory of Relativity, ...

Planets orbiting dead stars known as white dwarfs might be able to remain habitable thanks to general relativity subtly altering their motion. When stars like our sun run out of fuel, they expand and ...
