		graycat on Sept 22, 2024 \| parent \| context \| favorite \| on: What Is a Particle? (2020) So LIGO detects a gravitational wave. Optical telescope data indicates that the wave was generated 10 billion light years away from two neutron stars. So, then, LIGO today affected the two neutron stars 10 billion years ago? Affected them today?

Absolutely. But this not a causal effect, but it collapses the probabilities of what has occurred.
