Gravitation as a research area investigates the fundamental interaction responsible for the attraction between masses, spanning classical, relativistic, and quantum regimes. It encompasses the study of Newtonian gravity for weak-field, low-velocity systems, general relativity for strong-field and cosmological phenomena, and experimental and observational tests across scales from laboratory to astrophysical and cosmological. The field also includes gravitational wave physics, black hole and neutron star dynamics, precision tests of the equivalence principle, alternative and modified gravity theories, and efforts toward quantum gravity, such as loop quantum gravity, string-inspired models, and semiclassical approaches, with strong connections to cosmology and high-energy theory.
There is a question that often comes up at every public talk I do, and I have never had a good answer to it—well, not an entirely confident one. What's inside a black hole? The textbook reply is a singularity. Cross the event ...

Composing some 85% of the universe's total mass, dark matter betrays its presence only through gravity, unlike ordinary matter. Yet through new research published in Physical Review D, a team led by David Dunsky of New York ...
From reaching for a cup of coffee to tying your shoelaces, gravity shapes nearly all human movement. So how do our bodies react when that familiar force begins to change? Texas A&M University researchers are exploring the ...

A new study by Queen Mary University of London mathematician Professor Ginestra Bianconi proposes a new perspective on one of the deepest questions in modern physics: How can the universe become increasingly structured and ...

Listening to the "ringing" produced by black holes after they collide and merge could allow scientists to test Einstein's theory of general relativity under the most extreme conditions in the universe while unlocking the ...

More than a century after Albert Einstein first transformed our understanding of gravity, his general theory of relativity continues to withstand ever more demanding experimental tests. Now, an international team led by Ignazio ...
Our universe is known to be remarkably homogeneous and isotropic. This essentially means that matter is distributed evenly throughout the universe and that it looks almost the same in all directions.
Everything around us, from atoms and molecules to planets and galaxies, is governed by two extraordinarily successful theories of physics: quantum mechanics and gravity. Quantum mechanics explains the behavior of the microscopic ...

Hawking radiation is a form of radiation emitted by black holes, as theoretically predicted by Stephen Hawking. It suggests that black holes do not merely swallow matter—as had previously been assumed—but also emit very faint ...

Gravity, the force that attracts objects toward each other, is currently framed by Albert Einstein's theory of general relativity. This framework describes gravity as the curvature of spacetime, the invisible four-dimensional ...
