There are four high-quality gravitational wave detectors in the world: one in Italy, one in Japan, and two in the US. The Trump gang's new proposed NSF budget would kill one of the US ones.
While these detectors were expensive and difficult to build, they've *been built*. They are working. They are seeing amazing things, like the collisions of black holes in distant galaxies. Losing one will make it harder to study these events. We need several observatories to even locate them!
But the Republicans say: "Let's poke out one eye with a stick".
It's a small thing compared to the rest of the damage they're doing to the US. Just typical of their wilful destruction.
From the proposed budget:
“NSF supports two large physics experiments – the Laser Interferometer Gravitational Wave Observatory (LIGO) and the ATLAS and CMS detectors at the Large Hadron Collider (LHC). LIGO is the most sensitive detector of gravitational waves ever built and leads the worldwide effort to study the structure and evolution of the universe through gravitational radiation. LIGO makes use of exquisitely sensitive optical interferometers at two sites – Hanford, Washington and Livingston, Louisiana – to detect gravitational waves and, in collaboration with other, similar experiments in Italy and Japan, to determine the part of the sky from which the radiation originates. Past efforts by LIGO have led to the detection of hundreds of gravitational waves originating from the collisions of black holes, neutron stars, and other celestial objects. In FY 2026 NSF will operate only one of the two sites and will support a reduced level for technology development."
Also 60% cuts at ATLAS and CMS.
