Big Bang theory explains ?

  • A.Origin of universe.
  • B.Origin of sun.
  • C.Laws of physics.
  • D.None of above.

Answer: A

The Big Bang theory explains the origin of the universe: it holds that all matter, energy, space and time began in an extremely hot, dense state and have been expanding ever since.

Its two strongest supports are the redshift of distant galaxies, which shows the expansion, and the cosmic microwave background, the cooled remnant of the early radiation.
