Latest Gravitation Stories
This is actually kind of a serious question, especially with the populating-other-planets implication in the future.
Current use of satellites to monitor water tables helps explain the findings reported in Dean Walker's new eBook, Gravity Fields of Energy.
While some astronomers are looking for the existence of planets light years away from Earth, a team of Spanish researchers has suggested there could be at least two planets that have yet to be discovered in our very own Solar System.
The stage has been set for a explosion of apocalyptic proportions, as two distant supermassive black holes just one light-year apart are on a collision course that could result in the destruction of their home galaxy and release as much energy as 100 million supernovas.
Brazilian scientists have made advances in causing tiny particles to hover, or levitate, using sound waves. The development could have significant implications for improving safety when handling hazardous materials, as well as providing an opportunity for some mind-blowing kids/grown-up toys.
A story going around the internet claims we'll experience five minutes of zero-gravity on January 4th, thanks to Pluto and Jupiter lining up with Earth.
Brings a whole new meaning to an ISS "fly-over."
The most advanced system to date for studying fruit flies in space, NASA’s Fruit Fly Lab, is making its debut aboard the International Space Station.
A team of scientists hope to trace the origins of gamma-ray bursts with the aid of giant space 'microphones'.
Astronomers have developed what they are calling a “spotters guide” to black holes that could help scientists better detect the faint ripples of gravitational waves caused by black holes colliding millions of years ago.
General Relativity and Gravitation is a peer-reviewed scientific journal published monthly since its establishment in 1970. It is published by Springer on behalf of the International Society on General Relativity and Gravitation. G.F.R. Ellis and H. Nicolai are the editors-in-chief. The journal covers modern gravitational physics, encompassing all theoretical and experimental aspects of general relativity and gravitation. The journal’s main goals include public outreach through teaching...
Kepler's Laws of Planetary Motion -- The astronomer Johannes Kepler's main contribution to astronomy was his three laws of planetary motion. Kepler found these laws empirically by studying extensive observations recorded by Tycho Brahe. He found the first two laws in 1609 and the third one in 1618. Isaac Newton was later able to derive the laws from his laws of motion and gravity, thereby producing strong evidence in favor of Newton's inverse-square gravitational law. Kepler's First...
Gravitational Lens -- A gravitational lens is formed when the light from a very distant, bright object (such as a quasar) is "bent" around a massive object (such as a massive galaxy) between the bright object and the viewer. The process is known as gravitational lensing, and was one of the predictions made by Einstein's general relativity. Description In a gravitational lens, the gravity from the massive object bends light as a lens might. As a result, the path of the light from a...
General Relativity -- General Relativity is the common name for the theory of gravitation published by Albert Einstein in 1915. According to general relativity the force of gravity is a manifestation of the local geometry of spacetime. Although the modern theory is due to Einstein, its origins go back to the axioms of Euclidean geometry and the many attempts over the centuries to prove Euclid's fifth postulate, that parallel lines remain always equidistant, culminating with the...
Escape Velocity -- An escape velocity is the minimum speed at which an object without propulsion can move away from a source of a gravitational field indefinitely if there is no friction. This definition may need modification for the practical problem of two or more sources in some cases. In any case, the object is assumed to be a point with a mass that is negligible compared with that of the source of the field, usually an excellent approximation. It is commonly described as the speed...
