Snowmass2021 Cosmic Frontier White Paper: Fundamental Physics and Beyond\n the Standard Model

Le résumé fourni par la source

Gravitational wave detectors are formidable tools to explore strong-field\ngravity, especially black holes and neutron stars. These compact objects are\nextraordinarily efficient at producing electromagnetic and gravitational\nradiation. As such, they are ideal laboratories for fundamental physics and\nhave an immense discovery potential. The detection of black hole binaries by\nthird-generation Earth-based detectors, space-based detectors and pulsar timing\narrays will provide exquisite tests of general relativity. Loud "golden" events\nand extreme mass-ratio inspirals can strengthen the observational evidence for\nhorizons by mapping the exterior spacetime geometry, inform us on possible\nnear-horizon modifications, and perhaps reveal a breakdown of Einstein's\ngravity. Measurements of the black-hole spin distribution and continuous\ngravitational-wave searches can turn black holes into efficient detectors of\nultralight bosons across ten or more orders of magnitude in mass. A precise\nmonitoring of the phase of inspiralling binaries can constrain the existence of\nadditional propagating fields and characterize the environment in which the\nbinaries live, bounding the local dark matter density and properties.\nGravitational waves from compact binaries will probe general relativity and\nfundamental physics in previously inaccessible regimes, and allow us to address\nfundamental issues in our current understanding of the cosmos.\n
