Research news on Gravitational fields

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.

Weighing in on the mystery of the gravitational constant

The time had come to open the envelope, but Stephan Schlamminger, a physicist at the National Institute of Standards and Technology (NIST), wasn't sure he wanted to know the secret number that lay inside. For the past 10 ...

Dark matter does not defy gravity, study suggests

Does dark matter follow the same laws as ordinary matter? The mystery of this invisible and hypothetical component of our universe—which neither emits nor reflects light—remains unsolved. A team involving members from the ...

Collaboration uncovers how gravity influences qubits

A collaboration between Nordita, the Nordic Institute for Theoretical Physics, hosted by Stockholm University, KTH and Google Quantum AI explores how gravitational fields influence quantum computing hardware, laying the foundation ...
