Vast arenas of possiblity can be approached with ideas that really can't be falsified, not with language only. Asserting with an argument that one such idea is loony could be called 'rebutting' as used in practice or per the definition.

Math is much more than a collection of random words, not yet arranged. It boggles the mind to think of the skill and imagination required to come up with calculus as Newton did, perhaps at the same time as Liebnitz, though there is endless controversy about that.
