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.)
It's astounding that one can learn really cool and interesting stuff by posting random nonsense to the shitpost community, lol. Thanks for the link! That was indeed new to me ;)
There is correlation evidence on Mars too! I don't think it's been considered casual at this point, but Atlas Pro has a really cool YouTube video showing a lot of potential examples. The Hawaiian Islands were particularly convincing to me. I'll try and find the video.
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?
