When the famous Sherlock Holmes found out that his main homicide suspect was actually playing soccer with some 20 other players at the time of the crime, he “reasonably” concluded that someone else must have committed the crime. Why?
Simply because his reason told him that the suspect could not have been at the crime scene and at the soccer field at the same time. But how did we draw this “reasonable” conclusion? I guess it is out of experience. Sherlock, his friends, and everyone else never experienced someone being at two places at the same time.
But is the fact that we never experienced it enough to conclude that it can never happen?
It actually did happen! Not for a man though…
Quantum theory has proved that particles can exist at two places at the same time.
So imagine another Sherlock Holmes coming from the tiny world of particles facing the large Sherlock Holmes Here is the conversation they had:

- Why did you exclude this suspect from your investigation?
- Are you out of your mind! He was playing soccer at the time of the murder!
- So what? He could have been playing soccer and killing the victim at the same time.
- …Besides the murderer is a tall man according to all the witnesses. However the suspect is rather short...
- So what? He was tall when the witnesses saw him, but became shorter when you looked at him. That is very common in our world of particles. Tell me Sherlock, where did you learn these stupid rules?
- It is common sense..
- But who taught you this common sense?.
- Experience taught me.
Then if you were to have a different experience, you might have a different common sense?
- I don’t think so.
- Don’t you see my dear, that by being reasonable, you are being completely unreasonable!
