1 The time dilation of the foggoid is caused by the disorder of motion of the foggoid particles. Therefore for the foggoid, there should be b*s = (1 - tB / tA) , (1) where tB is the rate of time of the foggoid, tA is the rate of time of the observer out of the foggoid, s is the entropy, caused by antigravitation, of one mole of the foggoid particles, b is the coefficient, and b can be measured through the experiments. The relation between the entropy S and the temperature T can usually be found in a thermal physics textbook, in the chapter on the second law of thermodynamics. 2 It can be known from an experiment in ESP that, when tB / tA = 1.5 minutes / 9 minutes, that is, when tB / tA = 1 / 6 , (2) the foggoid is the non-present-time foggoid, and hence it cannot be seen. When tB / tA = 1 / 6 , the red shift z = 5 . Suppose a quasar which can be seen joins a galaxy; the red shift of the quasar is z1 , and the red shift of the galaxy is z2 . It can be predicted that z1 < z2 + 5 . (3) 3 In the non-present spacetime, the non-foggoid has a large value of uncertainty in the time, but when it has a small mass and a low speed, it has not the time dilation.
