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.
