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

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

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

A bizarre "cosmic glitch" in the theory of how the gravity of the universe works may have been mended. The strange glitch in Einstein's description of gravity in his theory of general relativity may ...

If gravity arises from entropy, scientists could unite Einstein's general relativity with the quantum realm while shedding light on dark matter and dark energy. When you purchase through links on our ...

The relationship between quantum mechanics and classical physics has baffled scientists for decades. In the quantum world, particles can exist in multiple states at once—a phenomenon known as ...

Planets that orbit white dwarf stars should be too hot to host alien life, theories suggest. But a new study accounting for Einstein's general relativity may rewrite that rule. When you purchase ...

Albert Einstein's theory of general relativity, which suggests that gravity is due to the curvature of space and time, is more than 100 years old. And it's holding up as researchers analyze the ...
