LIGO, the Laser Interferometer Gravitational-Wave Observatory, has recently achieved a major milestone in its quest to detect gravitational waves. Scientists have now been able to measure gravitational waves with a sensitivity that surpasses the so-called quantum limit. This is the first time a large-scale observatory has achieved such a feat, and it is a major step forward in the field of gravitational wave astronomy.

The quantum limit refers to the theoretical limit of sensitivity of a gravitational wave detector. LIGO is now able to detect gravitational waves with a sensitivity that is 10 times better than the quantum limit. This means that scientists are now able to observe gravitational waves in much greater detail than ever before, and this will help them to gain tremendous insights into the universe.
