    Gravitational waves are transient displacements in a gravitational field—generated by the relative motion of gravitating masses—that radiate outward from their source at the speed of light. [1] They were proposed by Oliver Heaviside in 1893 and then later by Henri Poincaré in 1905 as the gravitational equivalent of electromagnetic waves. [2] In 1916, [3] [4] Albert Einstein demonstrated ...

    The gravitational waves were detected on September 14, 2015 at 5:51 a.m. Eastern Daylight Time (09:51 UTC) by both of the twin Laser Interferometer Gravitational-wave Observatory (LIGO) detectors, located in Livingston, Louisiana, and Hanford, Washington, USA. The LIGO Observatories are funded by the National Science Foundation (NSF), and were ...

    Jan 14, 2025A gravitational wave is an invisible (yet incredibly fast) ripple in space. We've known about gravitational waves for a long time. ... These first gravitational waves happened when two black holes crashed into one another. The collision happened 1.3 billion years ago. But, the ripples didn't make it to Earth until 2015!

    11.06am ET: OK now we're seeing a simulation of how the gravitational waves actually originated from the merging of two black holes. The total power output in gravitational waves during the brief collision of these black holes was 50 times greater than all of the power put out by all of the stars of the Universe put together. Whoa.

  7. Proving that gravitational waves exist may not be LIGO's most important legacy, as there has been compelling indirect evidence for them. In 1974, U.S. astronomers Russell Hulse and Joseph Taylor discovered a pair of radio-emitting neutron stars called pulsars orbiting each other. By timing the pulsars, Taylor and colleague Joel Weisberg ...

    Gravitational waves are 'ripples' in space-time caused by some of the most violent and energetic processes in the Universe. Albert Einstein predicted the existence of gravitational waves in 1916 in his general theory of relativity. Einstein's mathematics showed that massive accelerating objects (things like neutron stars or black holes orbiting ...

    Dec 17, 2024gravitational wave, the transmission of variations in the gravitational field as waves. According to general relativity, the curvature of space-time is determined by the distribution of masses, while the motion of masses is determined by the curvature. In consequence, variations of the gravitational field are transmitted from place to place as waves, just as variations of an electromagnetic ...

  1. Gravitational wave

    Gravitational waves are transient displacements in a gravitational field—generated by the relative motion of gravitating masses—that radiate outward from their source at the speed of light. They were proposed by Oliver Heaviside in 1893 and then later by Henri Poincaré in 1905 as the gravitational equivalent of electromagnetic waves. In 1916, Albert Einstein demonstrated that gravitational waves result from his general theory of relativity as ripples in spacetime. Gravitational waves transport energy as gravitational radiation, a form of radiant energy similar to electromagnetic radiation. Newton's law of universal gravitation, part of classical mechanics, does not provide for their existence, instead asserting that gravity has instantaneous effect everywhere. Gravitational waves therefore stand as an important relativistic phenomenon that is absent from Newtonian physics. Wikipedia
