Which of the following is an example of a non-falsifiable hypothesis? A. There is a teacup orbiting the Milky Way galaxy. B. The
frez [133]
Hello!
In order to find the correct answer, you need to find a hypothesis that cannot be proven wrong. Out of the options in the prompt, all but one can indeed be proven wrong. The correct answer is A because there is no way anyone can tell if there is a teacup orbiting the Milky Way galaxy or not. We know that it can be proven wrong there is no life on Mars, the human species started in Africa and that humans cannot live without a certain amino acid. The only thing that really can’t be proven wrong (that is quite stupid) is the one about a teacup.

Upon studying the theory of falsifiability, I came across an example of a person who claimed they had invisible unicorns in their digestive tract. We know that this (incredibly dumb) example cannot be proven wrong because, well, there is no way to actually know what’s in someone.
