Gravitational collapse — in astronomy is the inward fall of a massive body under the influence of the force of gravity. It occurs when all other forces fail to supply a sufficiently high pressure to counterbalance gravity and keep the massive body in hydrostatic… … Wikipedia

gravitational collapse — Astron. 1. the final stage of stellar evolution in which a star collapses to a final state, as a white dwarf, neutron star, or black hole, when the star s nuclear reactions no longer generate enough pressure to balance the attractive force of… … Universalium

gravitational wave — Astron., Physics. (in general relativity) a propagating wave of gravitational energy produced by accelerating masses, esp. during catastrophic events, as the gravitational collapse of massive stars. Also called gravity wave. [1895 1900] * * * … Universalium
Gravitational wave astronomy — is an emerging branch of observational astronomy which aims to use gravitational waves (minute distortions of spacetime predicted by Einstein s theory of general relativity) to collect observational data about objects such as neutron stars and… … Wikipedia
Gravitational wave background — A possible target of gravitational wave detection experiments is a stochastic background of gravitational waves. The detection of such a background would have a profound impact on early universe cosmology and on high energy physics, opening up a… … Wikipedia
Controlled demolition hypothesis for the collapse of the World Trade Center — The controlled demolition hypothesis is a 9/11 conspiracy theory that claims the complete structural failure of the World Trade Center towers was not caused by the plane crash damage that occurred as part of the September 11, 2001 attacks, nor by … Wikipedia
