And if they really got it in the very, in the very middle, it could just hover there in the middle. It would be being pulled on on all sides. Now, the earth is not uniform a so locating exactly where that point is, and also, that point would move over time. But ah, still, the thought experiment is there. It is possible to make a ball hover in the centre of a gravitational object. Neat tatis co. I mean, i don't think we can do it, but definitely can't. No, can't. Even we can, we can barely scrape the surface of this planet. John, i know s a lot down there. We think that we're such a big deal, man, you know. And then it's like how, it's like how everybody in their little pond thinks that their pond is a big deal. You know, like you talk to people in the world of car sails, and there i they want to to you that they think car sales are superimportant. Talk to people in the world of podcasts, they like, fascinated by podcasts. Want to talk all day about podcasts. Earthlings, that's good. That's good. I aguree oui that. I'm not criticizing it. I'm just saying that earthlings are like, you know, like we think that earth is a big deal, really, like, we think about, almost all our thoughts are shaped by earthness. Maybe all oem yes, i think we weav we actualy have a question from agnes that talks about how shaped we are by earthness. Agnes asks, dear henkan john, how does your internal clock even work? Are you born with it? Hypothetically, would some one born on mars have a 24 hour or would it feel weird to live somewhere with longer or shorter days? Would it all get messed up? I have so many questions, agnes. Now, we don't, so obviously you don't know all the answers to these questions, because no one's ever been born on mars. But when we have put, like scientists have intentionally put people, sometimes people in space, sometimes people in nino, sort of artificially lit situations. Ah, in a situation where their day 23 point five or 24 point five hours long, so not much longer. And the they're getting the, you know, sort of daylight cycles, they get messed up. Their melotone and level get all weird. They're like, their sleep cycles mess up. They can't sleep as well. We are very, we are earthlings, and we are, we are defined by the way that the cycles of this anet, for sure. And i don't knowwoud like mars's day is a little bit longer than earth'sik, not a lot, and, but i still think tha it would probably be a really long kind of jet lag. And astronauts have to deal with this, because they sometimes operate on like, 23 and a half hour days. And people who are on earth working on mars missions have to deal with it because they're sleeping during the martian night a, which can be very difficult. In fact, one of, one of the people working on curiosity had just had a baby right before curiosity landed, so was on like, baby time and mars time at the same time. Od, boy, which sounds supermiserable. E ah, but the people making it happen out here. Ah, but yet, we, our bodies do not handle it well because we are earthlings. And so if we imagine a future where humans are basically the same, but we're able to travel to distant planets that have vastly different days, you know, orbiting vastly different stars, or whatever. Eh, we will continue to have a 24 hour sleep cycle, like like whatwe ave. We're not goin to have that forever. You know, my guess, my guess is that after like, years of on mars, or if, specially if you're born on mars, then probably your sleep cycle will adjust a but mars is, but it, but that's very different from like, a 30 hour day, or a 35 hour day, ye oror like a, you know, ten hour day yem. And in those situations, you're not going to, you are not going to be able to adapt as a human being and live on that daylight schedule, yes. Which is why, lot, so we are. I mean, just just to state the obvious, we are creatures of earth, which we often forget about because we are very weird.
