The First Few Minutes of the Universe

Explore the rapid and dramatic changes that occurred in the first few minutes after the Big Bang in this 28-minute video. Delve into the formation of the universe's basic building blocks, from the initial high-temperature state to the creation of protons and neutrons. Discover how the equilibrium between matter and antimatter was disrupted, leading to the dominance of matter in our universe. Examine the roles of electromagnetic radiation and neutrinos in the early cosmos. Learn about Big Bang nucleosynthesis and understand why this process eventually came to a halt. Gain insights into how these early moments shaped the universe we observe today, all while imagining the intense heat that would require SPF four quadrillion sunblock.
