A direct descendant of his research is the $ 300 million Laser Interferometer Gravitational-Wave Observatory, or LIGO, which in about 18 months will begin the latest search for gravitational waves, which still have not been seen directly.
42.
LIGO ( the Laser Interferometer Gravitational Wave Observatory ), and a number of similar projects, exploit the fact that gravity waves should cause space to stretch in one direction and shrink at 90 degrees to this direction.
43.
The optimal acuity of 0.4 minarc or 6 / 2.6 can be demonstrated using a laser interferometer that bypasses any defects in the eye's optics and projects a pattern of dark and light bands directly on the retina.
44.
The signal from these snapping strings, if they exist, should be detectable by the Laser Interferometer Gravitational Wave Observatory, which began science observations two years ago, operated by a multinational collaboration led by Caltech and the Massachusetts Institute of Technology.
45.
But an exception is the Laser Interferometer Gravitational-Wave Observatory, or LIGO, that is being built in duplicate, one near Richland, Wash ., and the other near Livingston, La ., at an expected cost to taxpayers of about $ 85 million.
46.
It will link scientists involved in four megascale projects in astronomy and physics : the Sloan Digital Sky Survey, the Laser Interferometer Gravitational-Wave Observatory and two experiments at the Large Hadron Collider at CERN to find the origins of mass.
47.
Together with colleagues he developed a number of key elements for the detectors of gravitational waves ( both the bars and the laser interferometers ), in particular the suspension of the proof mass with a relaxation time greater than 5 years.
48.
These astronomical systems will be of special interest to space-based gravitational wave detectors such as Laser Interferometer Space Antennae when they are built, because they will allow precision measurements of the gravitational field of a black hole for the first time.
49.
Changes to the length of the paths or the time taken for the two split beams, caused by the effect of passing gravitational waves, to reach the point where they recombine are revealed as " Laser Interferometer Gravitational-Wave Observatory ( LIGO ).
50.
If the 5-mile-long Laser Interferometer Gravitational-Wave Observatory ( LIGO ) in Livingston does, astronomers will get a map of an unseen sky, physicists may get a look at the earliest universe and the genius of Albert Einstein will be vindicated once more.
