Because outside of math, in science there is never any “proven!” moment. But you can range anywhere from fuzzy ideas, to untested hypotheses, to tested hypotheses, to lightly confirmed theories, to theories which are hard to tell apart from absolute fact.
The point is though, that there must always be room for correction and for new evidence to be accounted for.
Isn’t the astroid still a theory?
some signs point to both asteroid impact and the continious eruptions of the deccan traps. which is adding insult to injury for dinos.
Yeap, just like gravity.
