When considering the notion of infinity relative to spatial perception, one will typically consider the vast expanse of the universe. in 1928, Edwin Hubble demonstrated that the universe is expanding from a finite origin, a finite time ago. According to Stephen Hawking, the foremost expert on the origins of the universe, the universe is actually not infinite in volume, nor does it have an outer boundary because it appears to be forever moving away from an origin. This is known as the “no boundary condition” of spacetime. That is to say that although it is believed that the entire universe originated from a point of singularity and appears to be expanding forever, at any point in time, space is finite. Spatial infinity is therefore a concept that is directly related to the passage of time.
Directly related to the notion of infinity as defined by Hawking, Einstein's theory of relativity deals with the nature of the progression of time. Depending on the relative motion of observers and the strength of the local gravitational field, Einstein wrote that time can progress with different speeds. In particular, time effectively stops for objects traveling at the speed of light, but just as nothing can travel faster than light, time will not run backwards. Physicists call this phenomenon the arrow of time.
A difficulty with the arrow of time is that it is only observable in theory. For example, Maxwells laws of electromagnetism which describe propagation of electromagnetic waves including light, allow for solutions in which time runs backwards as well as forward. In reality, we can only observe those in which time runs forward; that is to say that all of the light we see comes to us from the past, and none from events that have not yet taken place.
So far, the most successful effort to explain the direction of time comes from thermodynamics. This area of physics attempts to explain the direction of time by analyzing the level of order and chaos in physical systems. If an isolated object changes its physical state on its own, it is much more likely that the next state will be less orderly than the previous one. If a crystal vase is dropped onto a concrete surface, it will shatter into thousands of pieces. Even though the vase will shatter predictably according to the laws of motion, the fragments of crystal will not spontaneously reconstitute into a vase from the floor, despite the fact that the formulas describing the catastrophic event are reversible. The 19th-century physicist Ludwig Boltzmann proposed an explanation of this thermodynamic arrow of time based on probability of all configurations of atoms that constitute a physical body. Of all possible configurations, there are significantly more of those that appear to us as disorderly, than those that appear orderly. Boltzmann thus provided a probable explanation of the second law of thermodynamics stating that entropy, or the measurable disorder of an isolated system, can only increase. In this direction, the second law of thermodynamics, as famously enunciated by Rudolf Clausius ( German physicist and mathematician considered one of the central founders of the science of thermodynamics) in 1865, states that:
“The entropy of the universe tends to a maximum."
Thus, if entropy is associated with disorder and if the entropy of the universe is headed towards maximal entropy, then many are often puzzled as to the nature of the "ordering" process and operation of evolution in relation to Clausius' most famous version of the second law, which states that the universe is headed towards maximal “disorder”.
The Origin series depicts entropy as a layered concentric propagation of physical events that influence the forms of subsequent layers. The various works explore explore both systems of order, and disarray.
