The Big Bang Trivia Questions

For the first 380,000 years, the universe was a hot plasma of protons and electrons. Atoms only formed when it cooled enough for electrons to be captured.

The CMB is leftover radiation from about 380,000 years after the Big Bang, now visible as microwave static across the entire sky.

The Big Bang wasn't an explosion in space—it was the rapid expansion of space itself from an infinitely dense point. No pre-existing space or matter existed.

Big Bang nucleosynthesis produced about 75% hydrogen and 25% helium in the first three minutes, matching what we observe in ancient stars.

The Big Bang happened everywhere at once, not at a single point. The entire observable universe was compressed into a tiny volume, but no center exists.

The expansion actually slowed for billions of years due to gravity. It only began accelerating about 5 billion years ago due to dark energy.
