Remove your personal information from the web at https://joindeleteme.com/SPACETIME Giant space rocks are definitely going to hit the Earth again. We actually do know how to deflect them, but only if we find them and correctly assess their risk. But the solar system is a chaotic place. How is it even possible to tell if a space rock will one day collide with the Earth?

you know I didn't actually expect that the whole "experiment" thing was actually intended as an experiment, and instead thought that it was simply a thematically fitting way to deliver oh-so-common prompt for engagement. Neat to actually see data was in fact actually being tracked there.
