Moreover the present instant t = 0 which represents the absolute certainty moment within our temporal (t > 0) universe, and this is the moment of time (i.e., t = 0) that divides the physical and virtual realities. From which we see that; future uncertainties are physical realizable consequences, but all the past deterministic consequences were the virtual reality since time is no longer existed within the past time domain i.e., (t < 0). From this conjecture we see that any hypothetical solution obtained from the past deterministic domain is anticipated to be deterministic. Nevertheless, every aspect happens within our temporal (t > 0) universe is a physical reality but non-deterministic. In other words every physical reality within the temporal (t > 0) universe are uncertainties that change with time. In other words, any deterministic science within our universe temporal (t > 0) is virtual as from strictly physically realizable standpoint. This is precisely the reason that classical sciences are deterministic. But this by no means that timeless (t = 0) solutions are useless, the fact is that all the laws, principles and theories were developed from the past certainty regime are still the foundation of our science. From which it tells us that; science developed mostly from the past certainties were deterministic, but science within our temporal (t > 0) universe are probabilistic or non-deterministic which changes with time.

Nonetheless, without the past deterministic consequences, it has no better way to determine the non-deterministic consequences. Thus we see that if temporal (t > 0) constraint is imposed on the past deterministic consequences in search for future non-deterministic solution, very likely physically realizable solution would emerge. From which we see that science is not supposed to be deterministic, science is a law of approximation. In view the nature of temporal (t > 0) space we see a temporal (t > 0) exclusive principle as stated: Empty space and temporal (t > 0) space are mutually exclusive.

Since physically realizable paradigm is depending on temporal space, it is vitally important to have a basic idea of our temporal (t > 0) universe, for which we exemplify the nature our temporal (t > 0) universe as depicted in **Figure 3**.

#### **Figure 3.**

*Shows a simplified diagram of our temporal (t > 0) universe. c is the speed of light. v is the radial velocity. In which we show that every subspace is moving radially toward the boundary of the universe, which is linearly proportional to the speed of light since light speed is the current limit.*

In which we see that every subspace has the same time within the entire universe. And our universe also has the same time with the same pace as the greater temporal pace that our universe is embedded in.
