![]() when you can say this about a theory, it's a pretty fair bet that the theory is correct. in fact, if you claimed that you could come up with such a single fact, now THAT would be dubious!Įverything we observe in nature supports the theory of evolution, and nothing we observe contradicts it. no expression which qualified as a mere fact could do a very good job of explaining the complicated process by which species have arisen on Earth over the last billion years. To say that a theory is inherently dubious because "it isn't a fact" is pretty much a meaningless statement. this is just a misunderstanding of what the words mean, and of how science progresses generally. This statement is poorly formed because it implies that a thing is a theory until it gets proven and then it is somehow promoted to fact. "Evolution is a theory, not a fact, regarding the origin of living things." On top of that I find it somewhat strange to claim that a theory doesn't have to be testable, if it's built up from hypotheses, which DO have to be testable. Logical deductions based on axioms can be proven, but not scientific hypotheses. Hypotheses can be tested/falsified, they can't be "proven". ![]() "In science, a theory is a well-substantiated, unifying explanation for a set of verified, proven hypotheses."īut there's no such thing as "proven hypotheses". What is a Scientific Hypothesis? - LiveScience.caused a migraine - but even if this were true, the migraine could have actually been caused by some other factors.īecause this observation is merely a reasoned possibility, it is testable and can be falsified - which makes it a hypothesis, not a theory. This is actually a logically reasoned proposal based on an observation - say 2 instances of drinking coffee after 2 p.m. ![]() For instance, "Migraines are caused by drinking coffee after 2 p.m. ![]() People often tend to say "theory" when what they're actually talking about is a hypothesis. This video further explains the difference between a theory and a hypothesis: If it is consistently true after considerable time and research, it may be on its way to becoming a theory.) (Note: Simply because a hypothesis is not found to be false does not mean it is true all or even most of the time. This is a hypothesis, an "educated guess." The scientific method can be used to test this hypothesis, to either prove it is false or prove that it warrants further study. Hypothesis: One might think that a prisoner who learns a work skill while in prison will be less likely to commit a crime when released. See also the Big Bang theory, germ theory, and climate change. However, simply because Einstein's conclusion has become a theory does not mean testing of this theory has stopped all science is ongoing. Theory: Einstein's theory of relativity is a theory because it has been tested and verified innumerable times, with results consistently verifying Einstein's conclusion. "No amount of experimentation can ever prove me right a single experiment can prove me wrong." - Albert Einstein To explain why a large set of observations are consistently made. To present an uncertain possibility that can be explored further through experiments and observations. General: A theory is the establishment of a general principle through multiple tests and experiments, and this principle may apply to various specific instances. Specific: Hypothesis is usually based on a very specific observation and is limited to that instance. Suggestion, possibility, projection or prediction, but the result is uncertain.Įvidence, verification, repeated testing, wide scientific consensusīased on a very wide set of data tested under various circumstances.
