Loosely coupled Time

The time as we understand is very tightly coupled. That is well defined. In other words before and after is well defined. We know for sure which happened first and which happens next. But it's it? Quantum theory disputes it. The Heisenberg Uncertainty Principle states that you can never simultaneously know the exact position and the exact speed of an object. Then time is not tightly defined or it is loosely defined.

The principal I propose is, we cannot exactly state which happened first and which happened next. But, we can state a loosely coupled set of events happen first and before another loosely coupled set of events.

Time is a loose concept. Our brains makes it well defined.

Special Relativity attempts to make time and also space well defined. It tries to give formulas to couple what happened in one frame by another moving frame.
Quantum theory approach is different, it accepts that time is not well defined.  The Copenhagen interpretation of quantum mechanics implies that after a while, the Schrödinger's cat is simultaneously alive 
and dead. The problem is, tightly defined concept of simultaneous.

Suppose the concept of time is something cooked in our brains, we can ask how can we see a star explodes to become a supernova and then a black hole. It is not correct to say time does not exist at all. Time is loosely  coupled, therefore, these happenings, from a star to supernova and then black hole, we cannot say which happens first, but this set of events happened before some other set of events.
