That's understood. Science is never the definitive answer, but I added the "authority" bit for a reason: if you don't know what the mass of an electron is or how you could go about finding out, you end up having to accept authority. But there are many things that are (currently) not open to a similar objective scientific approach. And those are our daily concerns, and the most contentious topics. The scientific method isn't going to help there.
