“Spacetime Uncertainty” –LIGO Going Quantum

Binary Neutron Stars


Starting up in 2024, the enhanced Advanced LIGO Plus detector of gravitational waves will embed the Heisenberg uncertainty principle to improve the machine’s ability to detect ripples in spacetime. One of the foundations of quantum theory, the Heisenberg principle states that it’s impossible to precisely measure certain properties, such as the position and momentum of an object, at the same time.
