The NSF Presidential budget contains huge cuts of Maths & Physics

Not good news for gravitational-wave or multimessenger astronomy "In FY 2026 NSF will operate only one of the two [LIGO] sites and will support a reduced level for technology development"
@LIGO is the NSF's biggest investment. It is the result of decades of work by scientists from around the world.
Having 2 detectors was key to making detections. Thankfully we do have Virgo currently
For multimessenger astronomy, you really need 3 detectors online to localise sources. With KAGRA still having a long way to catch up, and LIGO India only just starting construction, we'll have many years before we could make it back to current abilities even if everything goes perfectly
The LIGO detectors are not things that can be simply turned on and off. The 4 km arms are an amazingly high quality vacuum. It would be a major operation to have to re-establish this
The loss in expertise resulting from these cuts would be devastating. People with unique technical expertise will lose their jobs. It is heartbreaking
