Orac, have you ever thought at what speed you are moving in space? The earth moves at a speed of 30Km/s. The sun moves at a speed of nearly 250Km/s and carries the earth along with it. The galaxy containing the sun is moving at a still higher speed. The galaxy-cluster to which our galaxy belongs will be moving at a still higher speed (I think it will be close to one-third the speed of light). That is, we along with the earth is moving at a terrific speed. No superman has claimed to attain that speed!
