Predictions of noncommutative space-time
  An unified structure of noncommutative space-time for both gravity and particle physics is presented. This gives possibilities of testing the idea of noncommutative space-time at the currently available energy scale. There are several arguments indicating that noncommutative space-time is visible already at the electroweak scale. This noncommutative space-time predicts the top quark mass m_t \sim 172 GeV, the Higgs mass M_H \sim 241 GeV and the existence of a vector meson and a scalar, which interact universally with the matter.
