      The most important discoveries tend to be the ones that are not compatible with existing theories. For example, it would be a huge step for physics if black holes were produced at the LHC, but it is unlikely to happen. Of expected discoveries, direct detection of gravitational waves would be great because it would not only confirm one key prediction of general relativity but also open up a new window to the universe.

      I would say the observation of the cosmic background radiation has probably has the most profound impact on physics.
