谢谢扫盲。我还真搞不清中文怎么说。他的”理论“多着呢。就这”测不准“，小人还是怀疑。他说technology还是不够发达。比如说

Quantum Entanglement就貌似比光速快1000倍。是否”travel back in time“了呢？这”测不准“是不是就是因为我们现在还是测不精确到”billionth and billionth and billionth of a second“？他说”Just like light travel 7 times around equator in 1 second， human didn't know that until now！You closed your eyes， then opened eyes，the light already traveled rounds around Earth！ How can scientists be sure that particle really is everywhere instead of one point a time super／super／super fast！It SEEMS like everywhere at the same TIME？ Maybe it is too fast， it travels to the past， then now， when you measure it， it APPEARS to be ‘everywhere’！“ 

我treasure他这份敢想敢说的精神！觉得随着知识的累积，他会自己找到答案的。（我现在回答不了）
