building detectors sensitive to a range of gravity
wave frequencies.
«If we are able to do that, we can

wave detector in the future.»
LIGO, the Laser Interferometer Gravitational
Wave Observatory, is a pair of three - mile - long gravitational -
wave detectors in Washington and Louisiana that cost $ 365 million and took 11 years to
build, and yet they may just barely be able to pick up signals from the ultraviolent collisions that give birth to massive black holes.

wave detector, why we wish to
build bigger ones,» says Harald Lück, a physicist at the Max Planck Institute for Gravitational Physics in Hannover, Germany who is a member of the GEO600 and Einstein Telescope teams.

wave detector next year.
Although nobody has yet detected gravitational
waves,
detectors now being
built in the US and Italy («Gravity's secret signals», New Scientist, 26 November 1994), which will become operational early next decade, should be sensitive enough to detect the gravitational
waves released during the last few minutes of a binary neutron star merger.
The first person to
build a gravitational -
wave detector was Joseph Weber of the University of Maryland.
By adding a third gravitational
wave detector,
built by the VIRGO collaboration, to LIGO's Washington and Louisiana
detectors, the scientists involved in the search for gravitational
waves now can determine fairly accurately the direction from which a detected gravitational
wave signal is coming.
Professor Mavalvala worked with researchers at the US - based underground
detectors Laser Interferometer Gravitational -
wave Observatory (LIGO) Laboratory to

The gravitational -
wave discovery was made with the twin Laser Interferometer Gravitational -
wave Observatory (LIGO)
detectors, which are funded by the National Science Foundation (NSF), and were conceived,

To open the window to this «dark universe,» physicists
build gravitational
wave detectors like LIGO that reflect incredibly precise lasers along 2.5 mile - long (4 kilometer - long) «L» - shaped tunnels.
Einstein's famous theory of general relativity predicts the existence of gravitational
waves, but it's taken humanity over a century to develop the technological know - how to
build a
detector sensitive enough to perceive them.
