Gravity is usually presented as the most familiar of nature’s forces, the quiet background pull that keeps feet on sidewalks ...

A new concept for energy transfer between gravitational waves and light. When massive cosmic objects such as black holes merge or neutron stars crash into one another, they can produce gravitational ...

A physicist has proposed a bold experiment that could allow gravitational waves to be manipulated using laser light. By ...

Scientists using a continent-wide array of radio telescopes have made an extremely precise measurement of the curvature of space caused by the Sun’s gravity, and their technique promises a major ...

Test for echo: artist's impression of the merger of two neutron stars (Courtesy: LIGO) The first detection of gravitational waves in 2015 created huge excitement because it confirmed a long-standing ...

A rift runs deep through the heart of physics. The general theory of relativity, which describes gravity, clashes with quantum physics. In an effort to seal that physics fissure, untold numbers of ...

NEW YORK & STOCKHOLM--(BUSINESS WIRE)--Scientists at Applied Physics, an independent group of scientists and engineers who advise companies and governments on science and technology for both ...

The flow of time isn’t as consistent as we might think – gravity slows it down, so clocks on the surface of Earth tick slower than those in space. Now researchers have measured time passing at ...

Quantum theory and general relativity will only be unified when theory meets experiment Physics in the 20th century was built on two great revolutions: the general theory of relativity and quantum ...
