Not a scientist nor native English speaker myself, so I’m wondering: shouldn’t that technically say „hypothesis + evidence“ instead of „theory + evidence“? Which is of course nitpicky (if I’m even correct) in the context of a tumblr post, but I’m still curious
A hypothesis is a theory, one that is being tested. It’s got the same root word in both theory and thesis!
A theory in the scientific world/literature/common understanding is significantly stronger than a hypothesis.
That is one use of the word, sure. But it can be interchangeable with hypothesis. https://en.wiktionary.org/wiki/theory There is nuance to this term.
