  • Well, now you’ve piqued my curiosity. Got a link?

    The Wikipedia article I’m reading right now says that the Indian plate split from Gondwana 100 MY ago (33 MY before the Chicxulub impact), so that’s not the connection. Further down the page, it says that the plate movement might have sped up as it passed over the mantle plume from the impact that created the Deccan Traps (my interpretation, BTW; the science isn’t actually as settled as I’m making it out to be), but it seems to me that that wouldn’t change the “result” of the plate colliding with Asia and creating the Indian Subcontinent, only the timing of the collision.

    Considering that we’re in the midst of the Anthropocene mass extinction event already, I’d say it would be a certainty. The only question would be how bad it would get. Given how much larger that crater would be than Chicxulub, I’m guessing it would exceed the “Great Dying” (Permian-Triassic extinction event) to take the crown.

    Edit: The Wilkes Land Crater in Antarctica, which may be associated with the Great Dying, was “only” a little over 2.5 times larger in diameter than Chicxulub and thus still way smaller than the crater depicted. That said, I guess a nuclear crater wouldn’t be associated with a flood basalt “exit wound” at the antipode the way an impact crater might be, so maybe it wouldn’t be comparable.
