I see a lot of people on here saying that "Oh, such and such is only a theory"... They seem to be getting theories and hypotheses confused. A theory is a mostly proved collection of ideas that has some details that need to be worked out. Example: Gravity is still a Theory. We all agree that gravity exists, right? A hypothesis is an idea that is yet to be proved that was devised based off of observance of trends from experimental or environmental data. A theory starts as a collection of hypotheses. Once the central hypotheses of that collection are proved it becomes a theory. There are a few cases where in general parlance something is mislabled as a theory... The most major example I can think of is "String Theory"... But "String Hypotheses" just hasn't got the same ring to it. Adri "Is getting irritated by the ignorance on what a theory is" E. H.
