Physics Colloquium : Making the Invisible Universe Visible

Abstract 
Visible elementary particles and interactions are pretty well understood and we have a powerful mathematical structure to model them. But for reasons still unknown, many fundamental features of the visible world seem to have been determined by yet-to-be-understood properties of invisibles. Examples include the invisible energy field, related to the Higgs Boson that provides mass to fundamental particles, and virtual particles that flicker into existence then disappear but affect the forces of Nature and the behavior of matter. I will discuss interrelated topics with potential for breakthroughs on the invisible Universe: The many possibilities for the identity of dark matter and their relation to the dark sector. The matter- antimatter asymmetry of the Universe and its possible connection to phase transitions in the early universe. The new muon g-2 measurements at Fermilab, that may connect the effects of virtual particles to an explanation of dark matter, the existence of new forces in Nature, or to cousins of the Higgs boson that may change our understanding of the first instants of the Big Bang.
