The Craziest Theories About How the Universe Began

At 24:50 · chapter starts 24:39

The conversation moves to what may be the hardest question in cosmology: what came before the Big Bang? Tyson's answer is admirably direct — we have no idea — while noting that the mathematics of quantum physics and general relativity both point toward a multiverse: a medium that pumps out universes, with ours being just one. What caused the multiverse? Unknown. Tyson pushes back gently on the human impulse to demand answers at the frontier, noting that people who cannot tolerate uncertainty make poor scientists, and that origin stories across cultures reliably reflect the values and assumptions of the cultures that produced them rather than objective truths. He describes science as writing recipes for more data rather than filling gaps with guesses.

Microplastics: Were We Measuring Them Wrong?

“This Is The Culmination Of Everything I Know” - Dr Andrew … · Sep 14, 2026 Science

The widely shared claim that we have a credit card's worth of plastic in our brains may be a massive overestimate. Researchers used nitrile gloves to measure microplastics — and nitrile gloves shed microplastic particles onto the measuring device. A second paper found the original tool used was unreliable, and that we may have far less plastic than reported.

The Door-Keeping Experiment: Our Irrational Addiction to Optionality

Finding Your Life Path, Solved · Sep 2, 2026 Science

In Dan Ariely's door experiment, participants sacrificed the highest-reward door — repeatedly — just to avoid seeing other doors disappear. Even when researchers trained them to use the best door, they kept wasting clicks to maintain options. This is the bias that runs our lives: we'll take a worse outcome to preserve the feeling of optionality.

Dan Gilbert's Psychological Immune System: Why Your Brain Justifies Every Decision

Finding Your Life Path, Solved · Sep 2, 2026 Science

Dan Gilbert discovered that the brain has a 'psychological immune system' — it misremembers, reframes, and rationalizes to keep you satisfied with whatever you chose. The fear before commitment is all about potential regret. But after committing, your brain quietly starts justifying the choice — and the more irreversible the decision, the stronger the effect.

Peptides come loaded with a powerful narrative: regenerative, subcutaneous, targeted, cutting-edge. That narrative can genuinely move outcomes, especially for pain, energy, and recovery. The RCT's job is to quantify how much additional benefit comes from the molecule itself — above and beyond the compelling story surrounding it.
