Which of the following descriptions do scientist consider to be the most accurate regarding what actually happened during the Big Bang?

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.
