This is the third time I am reposting this below. I'm doing this so we are all clear what theory means in the scientific sense, it is not a mere guess or a hypothesis. Theory is the highest form of scientific knowledge, of course, one would have to be familiar with the scientific method to know this...

Theory is actually the last step in the scientific method. I'm reposting my post #850 so that people can be clear of how the word theory is used in the context of science. Theory is used to explain facts, like gravity. People seem to be conflating its use with hypothesis or mere guess...
Post #850
That's not really how the scientific method works -
The scientific method starts with observation. All angles cannot present themselves for observation, since some don't actually exist. The scientific method can be employed to test the veracity of false ideas, and if done correctly the idea will show itself as false.
Theory is the highest form of scientific knowledge, and it consists of facts. Theory in the scientific sense is much different than laymen use the term -

The sense that science uses the term is highlighted in red. Theory attempts to explain natural phenomena, the phenomena itself is 'fact'. I'm not trying to be pedantic, it is important to be specific regarding terms when speaking of the scientific method as opposed to using them in a casual sense. If not, equivocation will rear rear its ugly head...
