“One thing that seems different between this and special relativity is that there's no symmetry — in special relativity, both observers feel that the other one is aging slower, because they're both moving relative to each other. There's no true inertial path. But here, it actually does seem like there's a global sense in which one is the more relevant inertial frame than the other.”

…about two-thirds of the time. Hopefully, this benchmark doesn't saturate. And in the remaining cases, they almost always preferred the fine-tuned model over the base model. Serverless inference is live now, and serverless fine-tuning goes live next week. Learn more at cruso.ai slash thorcache.

…A second contribution is the good old special relativity correction, where moving observers look like they're going slow. And we'll have both of those effects. So you'll look like you're going even slower than you would have done than you would have done otherwise as you go around the black hole.

You're exactly right. Yeah, so in special relativity, if you and I are moving relative to each other, I think your watch is moving slow. You think my watch is moving slow. Neither of us is more correct than the other. The principle of relativity tells you that both of our perspectives is equally…

I intuitively get how energy equals mass, and then there's like these chemical bonds, those could dissolve, they release energy, the thing weighs less if those bonds are released. I even get that if the bonds between the protons and the neutrons are broken, that releases energy and makes the thing…

Yeah, that's a great question and really becomes relevant once you turn on quantum mechanics, which is beyond the scope of today's discussion. But classically, the black hole just sits there forever. And so you can just say, well, what happened to the protons and neutrons? You say, well, they now…
