Learn English – Word for theories that can neither be proven nor disproven scientifically

Homophobe has already been coined to mean a person having an aversion to homosexuality. And it turns out there is already a term, gynandromorph, for a creature of combined "male" and "female" type. One could surely refer to a person having an aversion to transsexuals or hermaphrodites as a gynandrophobe.

A hypothesis is a guess, based on data or logic of some kind.

So, if your hypothesis is: It is pointless to brush your teeth in the morning because no food has been eaten, not eating serves as the logic that bolsters your guess.

For a hypothesis to be viable, it needs be testable.
