Remember, kids: In proper scientific terms, an attempt to explain observable phenomena is called a "hypothesis". It is called a "theory" when it fits all the observable facts, and there is no observable evidence to the contrary. We don't call it a "truth" because there's always a chance that it might be overturned by later evidence - but as far as science is concerned, a "theory" is as hard as it gets. This is often confusing to people who dismiss science they don't like as "it's just a theory". But this distinction should be kept in mind when discussing things like the "Theory of Evolution", "Theory of Relativity", "Global Warming Theory", and "Dead Internet Theory". #PSA #Evolution #GlobalWarming #DeadInternetTheory #Science #Theory
