I have a Genie who is everywhere in my room. But when I call upon the Genie, it collapses to a single location, and stays at that location before diffusing back to fill the entire room. Just one call, and it collapses to a point, no matter how large the room is. Is it possible? How can a person educated in science say such non-sensical things? But replace Genie with "electron" and this idea forms the basic tenet of quantum mechanics. This is called collapse of the wavefunction. It has been estabished as the truth through numerous experiments. It defies our common experience of the macroscopic world.
I have two Genies now - one on Mars and one on Venus. They have equal probability of being red or blue. But, if I look at the Genie on Mars and it turns out as red, the Genie on Venus will also turn out red - without doubt. How is it possible? Of course, I am talking about entanglement. It's a pretty mind-boggling concept. Now, entanglement has become the basis of quantum computers. The world around us is more strange than our perception of it. What else is out there? I believe a lot - because these ideas have been recently discovered, and these are sprouts of a few genius minds. There may be concepts that our little minds can never fanthom.
