Suppose there were a nearby supernova, say 10 to 20 lightyears away. It's not close enough to incenerate the earth. Would such an event cause the solar wind to become swept away? If so, would there come a great earthquake as the wave went by the earth? I suppose that the gravity of such a wave before going by the earth would pretty much have the same effect as it does now. But it seems that there would be a sudden shift as the wave passed by. Everything is symmetrical in front of us, but then, within an hour or a few minutes everything is behind us. In other words, instead of solar wind all going out evenly in all directions from the sun, for a brief time it is all swept in one direction. So then there is a gigantic wall of concentrated solar particles headed in our direction. At first it is at the distance of the sun and does not have any effect. The net gravitational effect would be a slight tidal effect towards the sun. This direction of tidal effect would be in the same direction until the moment it passes by; it would get stronger as the wall approached earth, and then suddenly the tidal effect would be in the opposite direction. Would such a sudden shift cause a devestating earthquake? Thanks.
