What is a valid hypothesis?
It is an educated guess based on research and working knowledge. For a hypothesis to be considered valid, it must make a prediction that scientists can test using a repeatable experiment. If a hypothesis cannot be falsified through experimentation, it cannot be considered part of a valid scientific theory.
Why can’t a hypothesis be proven?
In science, a hypothesis is an educated guess that can be tested with observations and falsified if it really is false. You cannot prove conclusively that most hypotheses are true because it’s generally impossible to examine all possible cases for exceptions that would disprove them.
