Origin of the Universe is explained by _____.
Answer & explanation
Correct answer: option 4
The correct answer is Option (4) → Big-Bang Theory
The Big Bang theory says that the universe began about 13.8 billion years ago from an extremely hot, dense state and has been expanding and cooling ever since. It is supported by the moving apart of galaxies and by the faint cosmic microwave background radiation left over from that early stage.
Why the other options are incorrect
Option (1) Higgs Boson — Incorrect. It is a particle, found in 2012, linked to how other particles get their mass.
Option (2) Dark matter — Incorrect. It is unseen matter whose gravity holds galaxies together; it is a part of the universe, not an account of its origin.
Option (3) Large Hadron Collider — Incorrect. It is a particle accelerator at CERN, near Geneva, where the Higgs boson was found.
