    You joke, but meteorite impacts causing large igneous provinces on the opposite side of the planet might actually be a thing.

    (Uluru and Meteor Crater are provably not an example of this, though, for several reasons: they aren’t antipodes of each other, Uluru is five orders of magnitude older, and the phenomenon I mentioned would’ve been caused by way, way bigger impacts.)

      Do they have to be antipodal? If we imagine a clock face overlaid over an image of the earth, if a meteorite strikes vertically (i.e. parallel to the 12-6 line) at 11, could it result in a bulge at 7?
