Gravitational fields as a research area encompass theoretical, computational, and experimental studies of how mass-energy curves spacetime and produces gravitational interactions, primarily within the frameworks of general relativity and alternative gravity theories. The field includes analysis of weak and strong-field regimes, gravitational radiation, and the dynamics of compact objects such as black holes and neutron stars. It involves precision tests of gravity, modeling of gravitational lensing and cosmological structure formation, and development of numerical relativity techniques. Research also addresses quantum aspects of gravity, including semiclassical approximations, effective field theories, and attempts to reconcile gravitational fields with quantum mechanics.
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 ...
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 ...
