Ok, .. another 10 minutes of rest here will give my dick a chance to do 
the back of the envelope calculation.

My dick says, in 40 milliseconds Earth moves on the orbit 30 meters. Its 
distance to the position of Earth had it moved linearly is about 6 
nanometers, which is about 20 silicon atoms inside stone, the way 
silicon is distributed in it (surrounded by oxygens). I'm looking only 
at the crust.

So _EVERY_ silicon atom of the crust in Earth will penetrate through 20 
other silicon atoms, not at once, but in turns, as a wave traveling for 
40 milliseconds across the whole crust.

This is the case for Sun suddenly disappearing. Do the back of the 
envelope calculations for the case of Sun losing, say 20 Earth masses in 
one huge burst in a large storm. Assume the 20 Earth mass disappears 
instantly, and find out what kind of crashes appears in the crust on 
Earth as a result.
