Answer to Question 1

A

Answer to Question 2

The Universe was so small and hot during the early phases of the Big Bang that there was spontaneous particle creation from energy and annihilation. We can recreate the conditions of particle creation and annihilation at high energies using particle accelerators and thereby test theories of the Big Bang. Furthermore, we cannot actually see these early stages directly because the Universe is so dense that it is opaque.
