Which description is considered most accurate regarding what actually happened during the Big Bang?

• Two galaxies collided causing an immense explosion as stars crashed into one another

• All of what would become the universe was concentrated in a single small point, or singularity, which rapidly expanded into what is now stars, planets, galaxies, matter, and energy.

• All matter emerged from a massive black hole at the center of the universe.

• Parts of the sun were ripped off by massive internal explosions and were thrown into space where they cooled to become other things, like plants, comets, and other galaxies.
