Time, space and reality: an analysis from physics

When we discover the world, neither space nor time are shown to us and named as such, and we have neither rulers nor clocks independent from it. Practically, it is within the phenomena that we choose what allows us to think and to build space (material points declared to be bound together in an immobile way), and what allows us

The Block Universe idea, representing spacetime as a fixed whole, suggests the flow of time is an illusion: the entire universe just is, with no special meaning attached to the present time. This view is however based on time-reversible microphysical laws and does not represent macro-physical behaviour and the development of emergent complex systems, including life, which do indeed exist in the real universe. When these are taken into account, the unchanging block universe view of spacetime is best replaced by an evolving block universe which extends as time evolves, with the potential of the future continually becoming the certainty of the past. However this time evolution is not related to any preferred surfaces in spacetime; rather it is associated with the evolution of proper time along families of world lines

Space and Time, 2013

In the paper the Space – Time problem is considered as it is seen in the informational conception (“the Information as Absolute conception”) comparing with a number of existent physical and philosophical approaches. Since the conception is rigorously grounded (for the conception the existence, the truth, the self-consistence and the completeness of are proven), the notions “Space” and “Time” – which cannot be deduced from physics itself since are Meta-physical notions – obtain reasonable elucidation that is presented in the paper. Key words: space, time, Matter, special relativity, informational model, arrow of time, time flow PACC: 0330, 0455, 0170 PACS : 01.70.+w, 03.30.+p, 04.80.Cc

Time is actually an abstract entity which became part of Special Relativity. There has in fact been postulation that time is unreal but just an invention of the intellect. Whether time is an invention or actually real, it cannot be denied that it plays a very important role in our lives, e.g., without a watch to tell us the time practically all of us would be lost in time. This paper takes a look at the philosophical ramifications and difficulties of time, as well as time-travel, and clarifies things.

This paper examines the various arguments that have been put forward suggesting either that time does not exist, or that it exists but its flow is not real. I argue that (i) time both exists and flows; (ii) an Evolving Block Universe (`EBU') model of spacetime adequately captures this feature, emphasizing the key differences between the past, present, and future; (iii) the associated surfaces of constant time are uniquely geometrically and physically determined in any realistic spacetime model based in General Relativity Theory; (iv) such a model is needed in order to capture the essential aspects of what is happening in circumstances where initial data does not uniquely determine the evolution of spacetime structure because quantum uncertainty plays a key role in that development. Assuming that the functioning of the mind is based in the physical brain, evidence from the way that the mind apprehends the flow of time prefers this evolving time model over those where there is no flow of time.

Recognizing that there are many outstanding questions concerning the fundamental nature of Time a model is described herein which it is hoped will provide some of the answers. The model aims to draw parallels between our common experience of time and the known laws of physics which govern the universe. The core argument is an identification of the future and past with potential energy and entropy respectively. This assertion relies on the belief that time can only be measured by change in the universe and change is effected by motion in the present. The present is, therefore, represented by kinetic energy, the energy of motion, and time is a measurement of the rate of transformation from potential energy (the future), to entropy (the past). In this way the physical nature of the future and the past are revealed as integral parts of what is observed as the present. Each object is its own clock. Time is therefore relative to an object dependent in part on all measurable expenditure of...

History of philosophy of Time is full of separate attempts with different views to solve the problem of time. some of these attempts just disband the issue and some of them give up it with no answer. Yet the nature of time and its properties is a mystery and open question for both philosophy and science. for years by mistake people were think the problem of time is the issue of philosophy and some other else were believed that it belongs only to physics category, But now it is clear dissolving this problem is impossible without help of all categories where were challenge with time; for example physics, philosophy, language, psychology and so on. We consider three categories of all areas above to explain the conception of time and its problems: By help of physics, philosophy and psychology.
