If shrapnel bounces off the asteroid but doesn't accelerate it that would violate conservation of momentum?

If Dimorphos was a solid rock, though, there wouldn't be anywhere for the energy to go but into the asteroid. The shrapnel from the impact would have to bounce backwards or sideways, which would just add to the momentum along the approach vector.

I remember in the headlines after the impact everybody was amazed by how much more energy the probe delivered than predicted. Why were we so pessimistic? Isn't this a basic inelastic collision problem?

Unless this coating is cheap, nontoxic, and biodegradable, it's just kicking the can further down the road, really

Reply to comment by InterestingPatient49 in TIL Diophantus of Alexandria, a mathematician from the 3rd century, came up with many mathematical equations that took a long time to solve. The last one, Fermat's Last Theorem, was first stated in 1637 and was proved in 1995 by British mathematician Andrew Wiles. by dustofoblivion123
Yeah but "One of Fermat's Intermediate Conjectures" doesn't have the same ring to it

Turn that back into baking soda, make more cookies. Sustainable living
