The current understanding of the physical structure of the universe is bipolar. There is Einstein's theory of relativity, which explains the macroscopic behavior of the universe to many places to the right of the decimal point. At the other end of the size spectrum, there is the quantum theory of fields, which explains the observed behavior of fundamental particles to many places to the right of the decimal point. Although one should always be very reluctant to state such a position, the resolution of this bipolar state into a unified one may be the last, great discovery of physics.
