Was gonna come in here to ask...will this explain Nemesis as not a recurring event but rather a one-time event caused by that trailing brown dwarf (or the star itself) flinging comets all over the place. It would also explain a lot of other crater-rich surfaces dating back to that time...
- vidarh 12y agoNot without time travel... This was only 70 thousand years ago.
- iwwr 12y agoIf that's true it'd be hard to identify the responsible star since in a few million years it would be thousands of light years away and difficult to measure precise kinematics of it.
- logfromblammo 12y agoGiven the distances involved, anything that may have had its orbit altered by this event is extremely unlikely to have struck any solid surface in our system already. It may, however, lead to some additional bombardment a few million years from now. By that time, we might have computers of sufficient power working from an astronomical catalog of sufficient completeness to reverse-propagate the catalog far enough to actually blame the passing stars for kicking out comets in our direction.
