But we're getting better. And the thing about it, there's two things about it. One, we keep getting better technologies, better shielding. We can actually come up with, there's ways you could do active shielding with magnetic, you can create your own magnetic field around the ship. And so it'd almost be like Star Trek with, like, you know, a force field or shields or whatever. So there's ways that maybe we could do that. There's also the other thing that we don't know. We know exactly what radiation is out there. We don't know exactly what that radiation does to humans. The best we have to go on is, like, data from some of the atomic bomb survivors and radiation workers that work in, like, power plants and stuff to take some dose, but it's a different kind of radiation. So right now, the error bars are really big. So when we say, like, oh, 5% chance of cancer, that's taking a very conservative estimate. If we can find out what it really does to humans, maybe it's a lot more benign and maybe we could sharpen that pencil and say, yeah, it's acceptable.
