Comment on Would it be possible to model 9/11 using hot dogs for the planes?
Krusty@quokk.au 1 week ago0.67 percent the speed of light would be enough. That’s mach 5800, or 2000 km/s. A 50g hot dog would have around 10^11 J kinetic energy.
If you accelerated a 50g hot dog to 10 percent light speed you’d probably have enough energy there to destroy civilization.
