One-Minute Physics: Are unknowns part of the universe? Sandrine Ceurstemont, editor, New Scientist TV What's part of the universe?
You may think of it as incorporating everything that exists - both on Earth and in space - but could it also include the unknown? In this One-Minute Physics episode, film-maker Henry Reich delves into the notion of the universe as described by physics, distinguishing between the whole universe and what's observable. Technology. The role of symmetry in fundamental physics. The role of symmetry in fundamental physics is reviewed.
Until the 20th century principles of symmetry played little conscious role in theoretical physics. The Greeks and others were fascinated by the symmetries of objects and believed that these would be mirrored in the structure of nature. Even Kepler attempted to impose his notions of symmetry on the motion of the planets. Newton’s laws of mechanics embodied symmetry principles, notably the principle of equivalence of inertial frames, or Galilean invariance. Solar system. Saturn. Objects in the Solar System.
