Explanation
Option (b) is correct: The LIGO detectors detected the first gravitational waves produced by two giant merging blackholes in 2016. Gravitational waves are ripples in spacetime’s fabric brought on by cosmic catastrophes like neutron stars or black hole collisions. These disturbances are incredibly powerful, yet their signals are feeble and difficult to detect when they travel through distant regions of space and time. In other words, it took that long for the signals to reach Earth. As a result, the observatory provides a chance to go back in time and solve puzzles about the origins of the universe. Options (a), (c) and (d) are incorrect:
A wormhole is a hypothetical structure that connects dispersed places in spacetime. It is based on a unique solution to the Einstein field equations. It is also known as an Einstein-Rosen bridge or wormhole. Although wormholes are consistent with the general theory of relativity, it is yet unknown whether they truly exist. The Higgs field, one of the fields in particle physics theory, undergoes quantum excitation to form the Higgs boson, an elementary particle in the Standard Model of particle physics. The Higgs particle is a large scalar boson with no electric charge, colour, or spin in the Standard Model. A gravitational singularity, or spacetime singularity, is a point where the values used to describe the gravitational field become infinitely large, regardless of the coordinate system used. At this point, the distinction between physical laws breaks down, and space and time lose their independent identities, merging into an indistinguishable and undefined state.
