I myself can certainly feel how time is passing by and only need a watch now and then to synchronize my internal clock to the worldly one. I guess this ability is shared amongst us human. That is what makes it so difficult to try and explain to people that the time dimension, widely believed to be a fourth dimension beside our usual three, does not exist. In fact, I do not blame anyone for thinking I am nuts to suggest something like this, because everybody, or at least those somewhat interested in physics, know that space-time, invented by Minkowski and embraced by Einstein, for most of the hundred years since Einstein presented his theories of relativity has been regarded a real and true phenomenon. Available for travel-excursions into the past if only one could work out how.
What then does our senses tell us? That depends, and not on our speed, but rather on our state of mind. If we are bored, time seem to creep by, sometime almost slowing down to a standstill, whereas it seem to race by if we happen to have fun or be busy. That is why we have to synchronize now and then. We all know about this so that is no surprise to you, and because this happens many times a day it is only natural to regard time as something very real. After all, we use it every day and sense it passing, so how could it not be real?
No, time is real OK, but it works rather different from the way Minkowski and Einstein were thinking. However, the idea of space-time as a physical collection of available past instants need to be re-evaluated and eventually replaced by an elastic fabric of space which is capable to mediate the strain- and stress associated with vibrations of all sorts, because particles of matter are only excitations of vibrations and oscillations like those Erwin Schrödinger originally had in mind. I suppose the consistence of this substance would be reminiscent of an elastic solid in which no classic particle would ever be able to move. However the particles I am talking about, which actually are waves, just as Schrödinger was thinking, will happily move around here, driven by resonance with the aftermath of the oscillations produced by the big bang. The idea that particles is nothing but the visible excitation of a field, is not unique to cranky laymen like me. The following link will take you to the homepage of Professor Art Hobson who have had no problem with any quantum mystery since he realized that "There are no particles, there are only fields". The next step then I imagine, would be for those who think this is a viable idea, to try and find out how such fields could have come about and might work. I think I am on the right track but lack the mathematical ability to prove my points. On the other hand, the actually very simple ideas I am trying to explain would obviously be a large part of the remedy required if my suggestions were to be confirmed.
So, if our sense of time is real and space-time does not exist, then what is it that our senses detect? Oscillations. The elastic fabric of space, our complete universe, is still oscillating radially as a result of the Big Bang event. Each of these pulses of radial oscillation constitutes a present moment. -A "now". Because the entire volume of space oscillates radially between two extremes where one is larger then the other, the transit in volume between the extremes is interpreted as duration by our senses. In other words, as time. The duration of this present moment would be very short and could well correspond to the rather brief duration of Planck Time, about 5.4 x 10ˉ⁴⁴ s.
That is all time that exist then, the 5.4 x 10ˉ⁴⁴ s long (or perhaps short?) present moment. Everything else is only memory and expectation... But stop! What about space-time? Not needed. The elastic substance of space is storing all the space-time-events we need from one present to the next.
Traditionally the present moment was regarded a non-dimensional border between the future and the past, but that does not really explain anything. Especially not motion. To explain motion we need elastic space and duration. Another phenomenon that may be understood by leaving the traditional view behind and adapting to the suggested brief duration of the present is the world of the quanta because the rapid oscillation of space as described here is the cause of all quantum effects.
This rapid oscillation cycle of space every 5.4 x 10ˉ⁴⁴ s will provide stage for a Planck level "quantum foam" where local vibrations and oscillations of space may result in virtual particles popping in and out of existence during the course of each 5.4 x 10ˉ⁴⁴ s recurring duration of the present moment.
...And then we have motion... Nothing much to explain you might think, but motion is actually the key to understanding how it all works. First of all, why is motion so important? Well, you know about quantum effects?..Think about this: A particle in motion would every now and then encounter virtual particles which could alter the speed or direction of it in such a way that it would be very difficult to predict where and when it would eventually arrive. Making such predictions using Newton's first law of motion does however not seem to present any problem. Why? And what indeed compels an object in motion to obey this law which also is known as the law of inertia and trace its roots back to Galileo?
At present almost everyone thinks this problem was solved by the detection of the Higgs Particle at Cern. This link will take you to the Wikipedia page about the Higgs Mechanism. However, I do not see how this field could interact with the particles in the proposed way without slowing them down. For this reason I am rather suspicious of the proposed mechanism. The mechanism of the dynamic present not only endows the particle field in question with the correct amount of inertia the size of the field and its associated excitation (the particle) demand, but in order to satisfy Newtons First Law, the resonance with the Big Bang oscillations also deliver the linear momentum required to keep it going until deflected by an external force.
I think of the Higgs Field as the first experimental evidence of the fabric of space. The stuff that is actually oscillating, and whose different modes of oscillation would give rise to all the different excitations we see as particles of various kinds as well as providing the physical media to "wave in" for the bosons.
Actually, the fermions are also "waving" in this physical media, only they are longitudinal waves unlike the transverse waves of the bosons. Proof? Yes, at least circumstantial since the proposed model of fermions and bosons allow for a simple explanation of the mechanism responsible for the half and whole integer difference in spin between fermions and bosons. No such explanation is offered within the standard model.
