1 Using the relativity principle, Einstein is able to derive that the energy of an object can be written as For v = c, the energy is infinite. Hence you are never able to push an object faster than the speed of light! Even at rest, an object still contain an energy due to its mass: It opens up the possibility to convert mass into energy or vice versa.

2 但光是以光速 c 前進： 除非 事實上電磁波的能量與動量密度有一個關係： 光子質量為零，Massless 無質量的粒子必定以光速前進。

3 物體的速度不能超過光速

4 如果火箭快過光速，光將永遠趕不上火箭！ （光速恆定），也就無法反射回來！ 若有超過光速的物體，光速恆定就錯了！

5 因事件B的時間變號，事件A在後，事件B在前，小鬼以兩倍光速在事件B及事件A間傳遞訊息！
為何物體不能快過光速？ 從一個以4/5 c 速度移動的座標系來觀察： t t’ B 1 A 2c x x’ 2c A 1 B 因事件B的時間變號，事件A在後，事件B在前，小鬼以兩倍光速在事件B及事件A間傳遞訊息！ 以兩倍光速在事件A及事件B間傳遞訊息！ 事件B是因，事件A是果。 事件A是因，事件B是果。 因果顛倒！ 如果可以以超光速交換信息，因果率會被破壞！

28 微中子：電中性，無質量，與其他物質交互作用微弱，極難觀測

29 COSMIC GALL- John Updike
Neutrinos, they are very small. They have no charge and have no mass And do not interact at all. The earth is just a silly ball To them, through which they simply pass, Like dustmaids through a drafty hall Or photons through a sheet of glass. They snub the most exquisite gas, Ignore the most substantial wall, Cold-shoulder steel and sounding brass, Insult the stallion in his stall, And scorning barriers of class, Infiltrate you and me! Like tall And painless guillotines, they fall Down through our heads into the grass. At night, they enter at Nepal And pierce the lover and his lass From underneath the bed - you call It wonderful; I call it crass.

38 太陽製造出的 e 微中子變臉為 μ 微中子。 地面測得的 e 微中子與 μ 微中子數量比與理論計算不符，但總數是符合的。 微中子在行進中會變臉！

39 會變臉的微中子一定是有質量的！

40 2010年Opera 看到了第一顆在地表變臉的微中子，在CERN製造出的 μ 微中子變臉為 τ 微中子。

where erf is the error function. To 12 decimal places, the values for the 1-, 2-, up to 6-sigma points are:16                          Dark blue is less than one standard deviation from the mean. For the normal distribution, this accounts for about 68% of the set, while two standard deviations from the mean (medium and dark blue) account for about 95%, and three standard deviations (light, medium, and dark blue) account for about 99.7%.

55 狹義相度論有錯，因此需要修正：

56 狹義相對論是對的，但時空有意想不到的結構：

57 微中子多了一個空間維度可以運動

58 狹義相對論是對的，但角色有點混淆： 只有微中子是以狹義相對論的光速移動 光與其他物質因為黑暗物質的牽引所以移動較慢

59 實驗結果漏掉一些誤差沒有考慮進去！ 鐘可能因為地球引力影響而有不同走速！

60 實驗結果根本不可能看到許多微中子： 結果根本是錯的！

61 What now?
