Episode notes
Big Bang as Scientific Fact
- The Big Bang theory is considered a scientific fact, based on observation of the universe.
- Studying the universe is challenging, as we can only observe it from Earth and cannot conduct traditional experiments.
Expanding Universe
- Scientists have observed for about 100 years that the universe is expanding, with galaxies moving away from us.
- This expansion is a key component of the Big Bang theory, indicating a dynamic universe.
Andromeda Galaxy
- The Andromeda Galaxy is the only external galaxy visible to the naked eye.
- More advanced telescopes like Hubble and James Webb reveal a greater number of galaxies, demonstrating technological limitations, not Big Bang flaws.
