Is the tool that find the Gravitational Waves.
It's formed by 2 perpendicular tunnels that are 3 km long.
These 2 'Arms' forms a L shape and from the start of them there's a laser ray that is directionned into the two 'Arms'. At the end of these tunnels there is a mirror for each 'Arm' that reflects the laser and where these reflected rays meet each other there is a detector.

Gravitation Waves are also defined as ripples of the time-space.They can come from Black Holes, Neutron Stars but also from the Sun.

The first gravitational waves that they observed was created from the fusion of 2 Black Holes,and in the last fraction of the fusion they turned into the energy that become the gravitational wave that they could find. This is the first time that they had demonstred what Einstein had expected with his general relativity a century ago. They're measurable beacuse they alter the distance even if in a impercetible way.

They won the prize because they helped ligo to find and observe,after 40 years, the graviational waves for the first time
