From Caltech: "New NSF-Funded Physics Frontiers Center Expands Hunt for Gravitational Waves"


Kathy Svitil

Gravitational waves are ripples in space-time (represented by the green grid) produced by interacting supermassive black holes in distant galaxies. As these waves wash over the Milky Way, they cause minute yet measurable changes in the arrival times at Earth of the radio signals from pulsars, the Universe’s most stable natural clocks. 683 more words

An illustration of gravitational waves.It may be possible to draw energy from a vacuum using gravity, a theoretical physicist says.If researchers succeed in showing that this can happen, it could prove the long-postulated existence of the graviton, the particle of gravity, and perhaps bring scientists one step closer to developing a “ 16 more words
