The First Second of the Universe — What Really Happened?
In the first second after the Big Bang, the entire universe was born — space, time, matter, and all four fundamental forces — compressed into an incomprehensible firestorm smaller than an atom. We walk through every epoch from the Planck wall at 10⁻⁴³ seconds to the first stable nuclei, including the quark-gluon plasma, cosmic inflation, and the mysteries physics still cannot answer. If you've ever asked how everything came from nothing, this is where it began. #space #universe #spacedocumentary 00:00 The Vertigo of Lemaître's Discovery 01:53 The Question No One Has Answered 04:18 Misconception: The Big Bang Was Not an Explosion 07:53 The Universe Compressed Into a Calendar Year 09:53 The Planck Epoch: Where Physics Breaks Down 11:53 Symmetry Breaking and the Superforce 13:45 Inflation: The Universe's Violent Stretch 15:31 Quantum Seeds of Every Galaxy 18:18 Force Separation and the Higgs Mechanism 20:12 Fine-Tuning: Why These Specific Laws? 25:31 Quark Confinement and the Birth of Protons 30:18 Misconception: The First Second Was Not Chaos 33:34 Big Bang Nucleosynthesis: The Universe Computing 36:01 Baryogenesis: Why Matter Survived Over Antimatter 39:01 What the First Second Gave You 41:00 The Long Dark Wait and the CMB 43:54 The Planck Wall and Its Limits 49:00 Closing the First Loop: The Edge of Description 52:24 Closing the Second Loop: Three Theories of Fine-Tuning 55:09 The Hydrogen in Your Body Is Older Than the Sun 59:49 You Are the Universe Looking Back at Itself
