what they are. We can very accurately model their interactions and construct mathematical models predicting their behaviors on other “physical” objects, but have little real understanding of what the Universe is “really” like. I believe in the concept of an electron. I believe that, in some real sense, an electron exists. I believe that electrons interact with other particles, and these interactions can be fairly successfully modeled using mathematics. I believe that the current model of electron interactions will likely be modified in the future as we devise more and more delicate tests of observable properties.
It is not hard to believe in the existence of something that has some measurable interaction with matter.
Precisely the question my students ask me when I try to teach modern physics. The most fundamental physical constituents of the Universe — elementary particles, photons, and fields — are to a large degree utter mysteries, at least in terms of trying to describeIf you don’t know what it is, how can you believe in it?
