>For those who claim they don't "live by faith", please post the correct value for the Cosmological Constant (found in the Einstein metric) and enlighten the rest of us. Even Stephen J Gould, who died of cancer yesterday, at the age of 60, and Stephen Hawking both admit to an 'admixture of philosophy' in their respective disciplines. In other words, they begin with assumptions they assume are true but cannot prove. That's "living by faith". You have a fabulous career ahead of you in the natural sciences if you can do what Hawkings and Gould could not.
>JLKWrong. Science has no need and does not use faith, but the scientific method. You think something works in a certain way. Therefore you postulate an hypotesis that tries to explain - and predict - the world, or whatever it is you are trying to explain, in light of that hypotesis.
If it is shown by repeated experimentation, independent testing, predictions coming to pass, then it becomes a theory, which is the highest point it can reach.
If it is shown that you have a flaw, and all hypoteses and theories are falsifiable, then you discard it, or some aspects of it, and search for a new explanation or solution. Faith not needed or involved.
