Scientists made the first direct detection of gravitational waves in 2015. That high-frequency burst came from colliding stellar-mass black holes. That signal matched what Einstein’s general ...

New research suggests that a perplexing signal created by a pair of colliding black holes may have been warped by a space-time phenomenon known as gravitational lensing. This theory could finally ...
A new study published in Nature Astronomy indicates that the dense, star- and dark-matter–rich environments around supermassive black hole binaries pack on the order of a million solar masses into ...

For more than a century, quantum mechanics and Albert Einstein’s theory of general relativity have each passed countless tests, but physicists have struggled to reconcile the two. Now, scientists in ...
Gravitational waves offer an unprecedented laboratory for probing the fundamental nature of gravity beyond Einstein’s theory. In modified gravity frameworks—such as f(R) extensions, scalar–tensor ...
Scientists at the University of Colorado Boulder may have solved a pressing mystery about the universe’s gravitational wave background. That’s the name for the ripples in space and time that move ...
Introduction]We usually hear 'sound' with our ears and see 'light' with our eyes.We also feel 'gravity' that anchors ou ...
Chern-Simons gravity theories represent a class of extensions to general relativity in which a topological term, the Chern-Simons three-form, couples to curvature or to a pseudoscalar field. This ...
