The Story of Cosmology: The Big Bang, Dark Matter, Dark Energy & the Great Mysteries of the Universe

Description: This is an exploration of the greatest discoveries in cosmology, the great scientists and astronomers behind them, and the still unresolved mysteries of the Universe at the most extreme scales of time, gravity, and distance across the deepest space.

This is part of a larger script I wrote for the James Webb Space Telescope: https://youtu.be/zcTxuQZzJbQ

The Big Bang, Dark Matter, the Cosmic Microwave Background, Cosmic Web Filaments, the End of Greatness, Inflation, Dark Energy, and there's still so many questions about the nature of our Universe.

Tonight we learn what the current lambda cold dark matter big bang model of the universe says happened from the first few seconds to the first few million years after the universe was thought have come into existence.

We learn what older cosmological theories evolved into and how our conception of light, matter and energy has changed over that last few centuries as our understanding of them has deepened.

We learn what the biggest mysteries of physics and cosmology still are and about the huge gaps in our understanding of the cosmic dark ages, the dark matter halos around nearly all galaxies, and how the still-mysterious phenomena of the big bang, inflation, and dark energy is propelling galaxies apart.

Thanks so much for watching. Let me know what you thought. -Rich
