The 2016 announcement of the detection of ripples caused by the merger of two massive black holes billions of light years away confirmed the existence of which of the following?

Question

Accepted Answer

B. Gravitational waves, as predicted by the general theory of relativity. The 2016 detection of ripples in spacetime caused by the merger of two massive black holes billions of light years away, made by the LIGO observatories, confirmed the existence of gravitational waves, a phenomenon predicted a century earlier by Einstein's general theory of relativity. It had nothing to do with confirming the Higgs boson, which was a separate particle physics discovery, nor did it demonstrate wormhole travel or provide a full theoretical account of gravitational singularities, ruling out the other options. Hence option B correctly identifies what the observation confirmed.

Answer

A. The Higgs boson particle

Answer

B. Gravitational waves, as predicted by the general theory of relativity

Answer
