> mathematically capable of predicting every physical phenomenon we're capable of observing here on earth "Mathematically predict" is too strong. For example, we can observe the mass of the electron here on earth, but our theories do not mathematically predict it. There are many similar parameters whose values must be determined empirically. There's also the converse: properties we can mathematically predict, but for which we do not have a good theory. An example is the mass of the Tau: predicted by the Koide formula, but we don't really know why.
