When a journalist asked Einstein what time it is, he replied “time is what the clock shows“. A joke and a good way to avoid the deep question because of the lack of time required to explain it in depth. But it is indeed a difficult question of fundamental importance. What exactly is time?

If you consider this scripture (from the handbook of God, the Bible), as mentioned in 2 Peter 3:8, “one day is with the Lord as a thousand years, and a thousand years as one day“, time is relative and not at all linear. Einstein recognized the non linearity at least in conjunction with the space-time continuum. In order to travel through space, time is required. Traveling very fast, with light-speed for example, freezes or slows down the time outside the spaceship. At the same time mass increase. It is like the astronaut does not age relative to the people on the planet. So here we have a process that creates the effect mentioned in the Bible, 1000 years are like one day and one day like 1000 years.
Interestingly the Bible mentions that for God time is relative in both ways. It is 1000 years for one day and at the same time also one day for 1000 years. One aspect I encountered often during my studies of the scriptures, is the fact that the word of God is harmonious despite it is a collection of 66 books and letters and written by 40 different people. The spirit of God enables this harmony of thought. And it is the same spirit that creates in us a sense of eternity, as mentioned in Ecclesiastes 3:11 “He has even put eternity in their heart“. Eternity is not only a non stopping time flow, or a reservoir for time, but it is the very core of consciousness. So again, what is time?

Time, it seems, is not at all eternity. But time behaves like entropy, it enables entropy, therefore randomness. The contrary of time is … eternity? Really? If this is true, then let us consider what a mathematical equation is, 1 + 1 = 2, it is true for all eternity, it was true back in time and it will be true forever forward in time. There will never be a point in time where this truth, that 1 + 1 is equal to 2, will not be true. Math is not an opinion, but a fact. So is time an opinion? Because if eternity is made of eternal truths, the unchangeable structure, the crystalline forms, then is time a kind of vapor lingering on the hard surface of eternity?
In quantum mechanics, in the theory and in the mathematical equations, time is not always an important aspect. And yet we all agree that time pass, that it is like a flow, it cannot stay still forever. By observing a quantum state, an evaluation process is triggered, like a program that evaluates the probability, the potential the state has, and it will collapse to a definite point in time and space. After that it seems that the system (context) decides of the new state of the particle. It is like quantum mechanics is a level of abstraction of a bigger framework, inside a collective consciousness, a big spirit.
When a wave of probability collapse to a particle, the position of the particle becomes visible in time and space. This means, it can be communicated to each participant of this so called reality. So space and time is a framework for communication.
