Transcript context
…So, it sounds like you're saying that changing the laws of physics is not even Dyson sphere level crazy. Somebody could do it on some planet in the middle of nowhere. I'd say it's definitely substantially harder than Dyson spheres as far as the tech tree goes, but it's not magic. We're not actually changing the laws of physics. We're just changing the low energy laws of physics as they present to us in this scenario. Again, this is speculative, but it's not super duper crazy. It's a natural consequence of our best theories, or at least some of our best theories of quantum gravity, that they allow for this possibility. And there is a meta law of physics, the true laws of physics, be it string theory or whatever else, that you're not changing. That's just the rules of the game. What I'm describing is changing the way that the universe looks around you, changing the cosmological constant. So I think again, changing water into water vapor into water is a great analogy here. There's nothing actually -- the laws of physics are still the laws of physics, but the way it feels to live in that universe, the value of the electromagnetic constant is perhaps not an absolute fixed value. It can vary in different places. Similarly, the density of water around you, the viscosity would change. It'll be an environmental variable like that. How would they bleed this away?…
