Confirming a pulsar star would enable unprecedented tests of General Relativity. Such a discovery would revolutionize physics ...

A record-breaking gravitational wave signal let scientists "listen" to a distant black hole merger and put Einstein's gravity to its toughest test yet.

So far, the most accurate model describing gravity is still Einstein’s theory of general relativity. It states that gravity as we feel and observe it is a kind of side effect of the fabric of ...

The second reason is simple: location, location, location! The millisecond pulsar appears to be near Sagittarius A*, the ...

Some random article came up on google for me about how there is a new attempt to reconcile both QM and Relativity through some space time dimension field. The point being that wouldn't such a theory ...

If you asked an astrophysicist what is yet to be discovered in the universe, there’s a good chance they’d paraphrase Donald Rumsfeld: It’s full of known unknowns. Besides the regular matter and energy ...

Recent theoretical advances have underscored the significance of momentum space geometry in the realm of relativistic physics. Traditional notions of flat momentum space are being re-evaluated in ...

New research suggests Einstein's general relativity explains the rarity of planets orbiting two suns. In tight binary systems, relativistic effects cause orbital resonances that destabilize planets, ...

New impressions A visualization of a curved space–time “sea” from the general-relativity simulations carried out by the authors.(Courtesy: James Mertens) From the Genesis story in the Old Testament to ...
