1887年 邁克生-莫雷實驗 是想找到乙太, 實驗結果是不論方向為何, 沒有干涉出現, 所以證實乙太不存在. 2015年 LIGO 實驗, 使用與邁克生-莫雷實驗相似但大很多的設備, 證實了重力波的存在. 個人想法: 乙太並非不存在, 而是在四度空間, 也就是時空, 所以邁克生-莫雷實驗才會找不到, 而重力波可以扭曲時空, 所以重力波應視為第五度空間. 至於甚麼會改變重力, 質量改變就會, 而質量改變發生在原子核分裂或融合時, 這是強作用力, 所以強作用力應該可以視為第六度空間. In 1887, the Mikeson-Morley experiment was to find ether. The result of the experiment was that no matter the direction, no interference appeared, so it was confirmed that ether did not exist. The 2015 LIGO experiment, using equipment similar to but much larger than the Mikeson-Morey experiment, confirmed the existence of gravity waves. personal idea: It is not that ether does not exist, but in the fourth-degree space, that is, space-time, so the Mikeson-Morley experiment can not find it, and gravity waves can distort space-time, so gravity waves should be regarded as fifth-degree space. As for what will change the gravity, the mass change will happen, and the mass change occurs when the nucleus splits or merges. This is a strong force, so a strong force should be regarded as a sixth-dimensional space.
