By definition a Theory is nothing more than an unproven idea, and therefore until it becomes proven (and a Fact) is subject to change as more information about the area of study becomes available. Until it can be proven 100% of the time (e.g. Gravity) it will remain a Theory, and no matter how sound will be subject to revision until it can be proven 100% of the time.
edenham students trying to cheat and revise scientist theories?? you do that urself
New information can lead to revised theories.
The scientists often revise the hypothesis.
There is no absolute knowledge in science that can never be disproven even in principle. It does sometimes turn out that scientists are wrong, and what they considered to be a fact turns out not to be one. I would add that it is more usual for scientists to revise theories, than to reject what was considered to be a fact, but it does happen.
investigation into a subject in order to discover or revise facts, theories, applications, etc
Different scientists have different answers, derived differently, but all of the estimates of the age of the universe are between about 15.5 and 13.5 billion years.The fact is that scientists must always be prepared to revise their theories in the light of new evidence. It's possible that the universe is older still.
Like every other scientists, Greeks based their theories on observations, experiments, proofs, evidence and more.
