Just inside the site boundary, secluded from most of Fermilab, sits Leonard Baumann's rickety red barn. Baumann, like 55 other farmers, relocated 40 years ago to make way for the construction of Fermilab.
What is this stuff that fills the vacuum of space, accelerates the expansion of the universe, and accounts for 70 percent of everything? More than two dozen experiments aim to find out.
