The future of at least one of the U.S. LIGO observatories is in jeopardy as deep cuts to science programs are proposed by the Trump administration.

The Trump administration has called for shutting down either a Tri-Cities, WA, or Louisiana observatory that work in tandem.

The merger wasn’t just the biggest ever, but also an event so rare that it challenges existing models for black hole genesis.
