Falsifiability applies to the big bang theory because the big bang theory is not about the general concept of "a" big bang, but about specific models of how exactly the events very shortly after the big bang happened, which make testable predictions about all the consequences of those very early events - the distribution of matter and energy in the universe, properties of cosmic microwave background, etc; such models can predict observations/measurements (of ancients events) that we have not yet made, and be falsified if those observations disagree with the model predictions.
- rsj_hn 5y agoFalsifiability is feasible to some degree -- e.g. in history you can hypothesize that a civilization had copper and then look for evidence of copper artifacts. But in the physical sciences you have well-formed mathematical models that make very specific and precise predictions and can be tested to a high degree of accuracy. That specificity allows you to set threshholds like 5 sigma for acceptance of a result as being verified. "Did we find copper" is a bit different, and thus there is a fuzziness in history that you don't have in physics or chemistry, which is why we don't view history as being a science even though it benefits from use of the scientific method. Everything -- cooking, dating, gardening -- can make use of the scientific method, but at issue here is the trust that the public places in accepted findings of science and such trust is not justified in the fuzzier fields. People need to add big error bars in their heads when listening to results from social sciences and much smaller error bars when listening to results from physics.
