About luck or chances or probability…

This is what it looks like in the ordinary world:

Imagine that there is a diamond box, which is very hard to open. There is a glove in it, and if you would like to know if it is right or left handed, all you need to do is open the box, and you will learn what nature already knows: right or left handed. There is a 50-50% chance for each possibility.

Since the first man on Earth began thinking about physics, physics has been based on this truth.Einstein's relativity theory is based on this ordinary truth too.

This is how it looks these days at the atomic level:

Imagine that there is a diamond box, which is very hard to open. Before we open this box, we know there is a 50-50% chance if the glove is right handed or left handed. But not only do we don't know what’s in the box: Nature itself does not know either. In fact, in a way, the glove itself does not even exist when the box is closed. It is in some sort of ghostly state and not just only between being left or right-handed, but even in existence. It is only when we open the box (in quantum mechanics they actually carefully measure this "imaginary box" before and after) that this glove becomes one or the other. If we open this box, we force nature to make a decision.

In a quantum world, it’s not that simple: to be or not to be, because nature hasn’t made up its mind until the box is open. Even if you have 2 possibilities: left or right, the chances are absolutely not 50-50%, because of the complete uncertainty of the universe at an atomic level.

What if you have 2 diamond boxes? If you open one and force nature to make a decision, the glove in the other box becomes the opposite of the one in the open box and we know this without opening the box, because we know 1 thing for sure: they exist in pairs. Can these imaginary quantum gloves communicate with each other? So if it is true and they can communicate with each other and compare to the relativity theory: nothing goes faster than light, that means to transfer any message between these gloves needs time even if time is relative to each glove. What if we opened these boxes at exactly the same time, then there wouldn’t be any time for the message to travel? But actually the reality is: even in this case if you open the boxes at the same time and far away from each other, they become a pair of each other. Compared to the relativity theory, it is just not possible.

So this experiment has become a paradox (so called EPR experiment). Most physicists regard the EPR paradox as an illustration of how quantum mechanics violates relativity theory. Most physicists believe there has to be a connection between relativity and quantum mechanics because they are not complete without each other.

The quantum mechanics stats: there is an absolute limit to what we can know about nature at the atomic level, and nature itself has the same kind of limit about itself at the atomic level too. Its stats: the universe is run on chance, and nothing is certain.
