Part of the theory also had the Deccan traps (the INdain subcontinent) had moved between its present position and the time of the impact.
Sounds right, that antipodal idea was rejected, in part, because they aren’t exactly opposite.
I see no reason why rejecting the antipodal theory means there was not an effect in India from the Yucatan event. That would only seem valid if the rock came straight at the earth. What if it hit at a moderate angle? Also, in the past several centuries I have detected a pattern of large earthquakes and major volcanic events coming around the same time.
