Why is LIGO in Louisiana?
Why is LIGO in Louisiana?
Such vibrations can drown out the telltale signals of gravitational waves in a sea of noise, just as light pollution drowns out the fragile light of distant stars. In the end, the desert of eastern Washington, and the forests of Louisiana were chosen as the locations of LIGO’s two detectors.
Where in Louisiana is the LIGO facility located?
Livingston Louisiana
LIGO Livingston is located in Livingston Louisiana, in a vast, humid, loblolly pine forest. Home to one of LIGO’s two gravitational wave detectors, our facility operates in tandem with LIGO Hanford to listen for the faint whispers of gravitational waves from the most energetic events in the universe.
Why is LIGO important?
The Laser Interferometer Gravitational-Wave Observatory, better known as LIGO, was the first experiment ever to directly detect these ripples in space-time, so it’s the first direct physical evidence that they actually exist.
Who founded LIGO?
Rainer Weiss
The very idea for LIGO came to Rainer Weiss in the early 1970’s when, as associate professor of physics at MIT, he had to find a way to explain gravitational waves (a prediction of general relativity) to his students.
What can LIGO detect?
Though its mission is to detect gravitational waves from some of the most violent and energetic processes in the Universe, the data LIGO collects may have far-reaching effects on many areas of physics including gravitation, relativity, astrophysics, cosmology, particle physics, and nuclear physics.
How is LIGO so sensitive?
Those correlations occur naturally in the light within the LIGO instrument. As it bounces back and forth between the two mirrors, it exerts a force called radiation pressure on the mirrors. This process induces a correlation between the amplitude and phase of the photons that have been inside the instrument.
Who won Nobel Prize for LIGO?
Rainer Weiss ’55, PhD ’62, professor emeritus of physics at MIT, has won the Nobel Prize in physics for 2017. Weiss wins half the prize, sharing the other half of the award with Kip S. Thorne, professor emeritus of theoretical physics at Caltech, and Barry C. Barish, professor emeritus of physics at Caltech.
How long do gravitational waves last?
Merging neutron stars produce waves that last longer (around 30 seconds) than this new signal, while merging black holes might more closely resemble bursts (that last around a couple of seconds).
How far can LIGO detect?
Most sensitive: At its most sensitive state, LIGO will be able to detect a change in distance between its mirrors 1/10,000th the width of a proton! This is equivalent to measuring the distance to the nearest star (some 4.2 light years away) to an accuracy smaller than the width of a human hair.

What is the Science Education Center at LIGO Livingston?
LIGO Livingston is also home to LIGO’s Science Education Center, which hosts schools, teacher workshops, tours and monthly Science Saturdays – where the public is invited to explore the science and engineering that underpin our quest to study the universe via gravitational waves.
