Quote:

Science is much more relativistic than thinking in 'true' and 'false', they tend to use 'valid' and 'invalid' instead. Science is looking for truths of course, but you can't prove something to be true, only whether or not a theory is valid for the time being.

You are right about that, and that is rather what I meant. Shouldn't have used the words "true" and "false", sorry for that.
