The recent detection of gravitation waves (GW) from the merger of two black holes of about thirty solar-masses each with the ground-based LIGO facility has generated renewed enthusiasm for developing even more sensitive measurement ...

(PhysOrg.com) -- Ocean waves can be incredibly strong and very difficult to block completely. When a wave moving across the ocean interacts with a buoy, the wave can be slightly dampened, but will still pass by if its wavelength ...
Venus is known both as the "planet of love" and the Earth's "evil twin". And although research suggests its environment is more hellish than romantic, there's actually a lot we don't know about our celestial neighbour. Now ...

Drop a marble and a cannon ball off the Leaning Tower of Pisa at the same time and they will hit the ground at the same time. That fact is explained by Albert Einstein's theory of gravity—general relativity—which predicts ...

A team of physicists affiliated with several institutions in the U.S. has collaborated on a paper that discusses the possibility of using the Laser Interferometer Gravitational Wave Observatory (LIGO) to search for evidence ...
The sun's core rotates nearly four times faster than the sun's surface, according to new findings by an international team of astronomers. Scientists had assumed the core was rotating like a merry-go-round at about the same ...

(Phys.org)—James Quach, a research fellow at Tokyo University is suggesting that it might be possible to observe a gravitational Casimir attraction by carrying out an experiment he has envisioned. In his paper published ...
A group of theoretical physicists, including two physicists from the University of Groningen, have proposed a 'table-top' device that could measure gravity waves. However, their actual aim is to answer one of the biggest ...
