Gravitational Waves Detection

The detection of gravitational waves from merging black holes is the correct answer. On September 14, 2015, the LIGO (Laser Interferometer Gravitational-Wave Observatory) detected gravitational waves from the merger of two black holes about 1.3 billion light-years away, confirming a major prediction of Einstein's General Relativity theory. This historic detection opened a new window for observing the universe. Statement (a) is incorrect: Higgs boson particles were detected at CERN's Large Hadron Collider, not from black hole mergers. Statement (c) is incorrect: While wormholes are theoretical, their existence has not been confirmed. Statement (d) is not the primary significance; while black holes contain singularities, the observation's importance was the direct detection of gravitational waves. The 2017 Nobel Prize in Physics was awarded for this gravitational wave detection. > Gravitational waves = ripples in spacetime from accelerating massive objects (confirmed via LIGO black hole detection). Answer: b.
