Finding unsoundness bugs isn't the most unusual, yes. But this one is unusual in how simple the code that causes it can be (see the versions of the reproducer code in the comments). For other unsoundness bugs, the code would need to contort itself a lot to avoid the compiler checks.

Reversing time on an attracting force still gives you an attractive force. Velocity is reversed, but acceleration isn't.

Imagine a ball being thrown up and then falling down, in a parabola. Reversing a video of that still gives you a video of a ball in a normal parabola trajectory.

The main reason that we use real numbers is because we need real numbers to do calculus, at least in the normal way. And to do physics, we need to do calculus. You can keep approximating integrals as sums of very large number of terms, but it gets unwieldy to handle symbolically.
