(Phys.org) —One of the more controversial theories of quantum gravity, which attempts to unify quantum mechanics and general relativity, is semiclassical gravity, which was proposed in the 1960s. As its name suggests, semiclassical ...
(Phys.org) —Over the next five years, Mansi Kasliwal writes in an astrophysics perspective in the journal Science, researchers will begin setting up experiments designed to detect gravitational waves. Kasliwal, an astronomer ...
(Phys.org) —Mathematics is, in essence, an artificial language for precisely articulating theories about the physical world. Unlike natural language, however, translating different classes of mathematics can be difficult ...
(Phys.org) —A strange stellar pair nearly 7,000 light-years from Earth has provided physicists with a unique cosmic laboratory for studying the nature of gravity. The extremely strong gravity of a massive neutron star in ...
