Which of the following is an example of a non-falsifiable hypothesis? a. there is a teacup orbiting the milky way galaxy. b. there is no life on mars. c. the human species started in africa. d. humans cannot live without the amino acid methionine

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.

The non-falsifiable hypothesis listed above is A. There is a teacup orbiting the Milky Way galaxy.

A non-falsifiable hypothesis is one that cannot be proven to be either right or wrong and there are two main reasons for this:

The hypothesis is based on a subjective premise. For instance, saying football is better than baseball. This is subjective because it depends on the person and so we cannot say for certain which is better or worse.Based on our current technological abilities, it is impossible to prove the hypothesis either wrong or right.

We cannot prove that there is a teacup orbiting the Milky Way galaxy because we simply do not have the technological capacity to build a vessel that can go around the Milky Way to research this so it is a non-falsifiable hypothesis.

All the other options can be proven to either be right or wrong because:

we can go to Mars to check if there is any life, we can look at fossils to find out if humans came from Africa and,we can test to see if human cells survive without amino acid methionine.

We cannot however, confirm if a teacup is orbiting the Milky Way so this is non-falsifiable.
