Top quark

One top quark weighs about as much as one atom of tungsten. Since top quarks are so massive, scientists have been able to make predictions about the mass of the Higgs Boson, the only type of boson with an intrinsic spin of 0 (scalar boson). Unfortunately, top quarks are only believed to be able to exist for 5x10–25 seconds.
