The Fragile Setup of Our Universe: "Some of the dials, not much of a change, but there's a couple of very important ones that involve the particles, the forces, and the universe as a whole, where seemingly rather small changes would make a dramatic effect to the way our universe would have played out."

The Rarity of Our Universe's Talent: "The ability of stars, planets, galaxies to form, it's a rare talent. It's not one that every universe that we can calculate, that we can imagine has."

The Fate of the Universe: "Because you can make a universe. I could make it very easily. Just turn a dial a little big, and everywhere in the universe has the same sort of density of stuff we see in in almost every galaxy. No stars, no planets. Just just a boring hydrogen soup where one particle hits another particle every, you know, 2nd Thursday, and that's all that happens in the history of the universe."

The Mystery of Existence: "Why is there a life permitting place at all anywhere?"

The Evolution of Fundamental Physics: "What I meant by that was our understanding of what what's the fundamental stuff we're made out of changes with time. We we keep doing physics. Now if you'd gone back, you know, 70, 80 years, we we wouldn't be talking about quarks, which what we think we're made out of. We'd be talking about protons and neutrons. And we we'd say, okay. What if I change those numbers? And and and this discussion would still look like, you know, if you change this number a bit, something would go wrong. And all I'm saying there is, okay. It's possible that tomorrow a new theory comes up."

The Debate on Fine-Tuning: "But I I would argue fine tuning needs to consider all the possibilities."

The Hardest Question in the Search for Life: "I've made hey. I've made a lovely planet out there. It puts all sorts of chemicals on it. I'll just hit it up for a bit with a star. Will anything start jumping around at any point? Right? Will will a will a cell form will will anything that we could call life be there?"

"Trusting Theories in Cosmology: Do I really trust Einstein all the way? And the answer is now, actually, we've got this other theory about how things work around here called quantum mechanics."

"If I lived in your multiverse, would I expect to observe a a a universe like this one, or are most of the life forms in a different sort of universe?"

The Universe Knew We Were Coming: "It's you know, having reviewed just the basics of physics went, looks like the universe knew we were coming."
