Quantum mechanics usually applies to very small objects: atoms, electrons and the like. But physicists have now brought the equivalent of a 10-kilogram object to the edge of the quantum realm.

LIGO is designed to detect gravitational waves, but it is also proving to be a fantastic laboratory for pushing the limits of quantum physics. Now, an international team of researchers has cooled the ...

A set of four mirrors used by the Laser Interferometer Gravitational-Wave Observatory (LIGO) to detect ripples in space-time have been cooled down so much that they are nearly at their minimum-energy ...

The breakthrough could lead to even more gravitational-wave discoveries for the LIGO team. When you purchase through links on our site, we may earn an affiliate commission. Here’s how it works.

The National Science Foundation funds LIGO observatories, and currently, they are working on applying updates to allow the observatories to reach further into the cosmos. Currently, there are LIGO ...

LIGO, the Laser Interferometer Gravitational-wave Observatory, has been called the most precise ruler in the world for its ability to measure motions more than 10,000 times smaller than the width of a ...
