Yeah. The really interesting thing is, like, we know we have a lot of data. We know what happens in zero g because we have a lot of us that have been up to the space station and Skylab and mirror and all that, and we have tons of data at one g, because all of us every day live in one g. We don't really have any data in between. So the question is, is a half a g half as good? Or maybe it's like 80% is good, right? And so is it linear or is it nonlinear? We don't know. And that's why if we send people and we live on the moon, or we go to Mars and we live on Mars and we have data, like on the moon, it's about of the earth's gravity. So we'll get points in between, and then we can figure out if this thing is. There's a lot of stuff that happens to you that may be completely solved with even just the smallest amount of g, but we don't know.
