Face it, physicists.
There likely is no Higgs boson, and there likely is no dark matter either.
Our current theories are decent as far as they go, but we will likely need to discover a new theory, and undergo a paradigm shift, to understand what we now call "dark matter" and gravity.
EDIT - July 4, 2012: I guess it's time for me to eat my shoe! Apparently, a new particle was found at energies where a Higgs boson was expected. Congratulations to everyone involved in the discovery!
