Course 158: Big Bang to Silent Whimper: A Brief History of the Universe
Leader: David Clark
Description: The short story of our universe from violent birth to peaceful (?) death. If you want to know how everything came from nothing in the Big Bang, are curious about the "real" nature of space and time, want to learn about terrifying "hidden" forces, black holes, exploding stars, nuclear power, exotic quarks, neutrinos, the Higgs Boson, "antimatter" - AND how humans were created literally out of stardust - this may be a course for you! We will gently introduce at a non-rigorous level some basic cosmology and a FEW ideas from Newton's "classical" physics, Einstein's shocking relativity theories, and just a touch of "weirdness" from quantum mechanics.
Curiosity is a strong prerequisite but science background is not!
- The Universe. Stars, galaxies, black holes, light, radiation, Runaway galaxies, Einstein's blunder, the universe expands.
- Creation. The "Big Bang" creates space, time, matter, energy, the Four Forces, the simplest particles - from "nothing".
- Pioneer Particles. Quarks, electrons, protons, neutrons, simple atoms form. Light floods the universe.
- Stardust. Gravity forms stars, fusion reactions form elements, stars explode to spew stardust into space, our solar system forms.
- Humans. Evolution creates humans on one tiny planet. Humans discover (create?) some of the Laws of Nature.
- What happens next? Dark matter and energy. Runaway expansion and the death of everything by "vacuum"? Maybe.
