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.

What are two important pieces of evidence we have for the Big Bang?

• Ptolemy’s work on epicycles and Hubble’s law (the expansion of the Universe)

• Hubble’s law (the expansion of the Universe) and cosmic background radiation

• The fact that we have multiple Universes to compare and study and cosmic background radiation (CBR)

• The abundance of hydrogen, helium, and lithium found in the Universe and Ptolemy’s work on epicycles
