A radical new theory of time and motion has been proposed by a 27-year-old college dropout named Peter Lynds. (Take this as a hoax?) His paper was supposed to have been published in the August issue of Foundations of Physics Letters. He proposes that there isn't a precise instant underlying an object's motion; And the objects position is constantly changing over time, and as such, never determined; it also doesn't have a determined position at any time. In short Time does not flow. The assumption, that objects in motion have determined positions at any time, dates back at least 2,500 years. Time was thought of as physical, definable quantities, and that motion can be considered as a flow of frozen moments, or instants, of time. Lynds claims his theory solves Zeno's famous paradox, "Achilles and the tortoise. " A tortoise gets a 10-meter head start in a race" against Achilles. Zeno says the tortoise can never be passed. His logic: When Achilles has run 10 meters, the tortoise will have moved a meter; Achilles goes another meter, and the tortoise crawls 10 centimetres more. The race continues in this ever-spiralling and incremental fashion. Lynds claims the paradox result from the incorrect physical assumption that there are a succession of moments and that objects in motion have determined positions. Hum, we know that there is no paradox in real life, Achilles eats the tortoise. Heisenberg`s uncertainty principle certainly applies to particles, it seems strange that no-one had applied it to time it-self...or had they? String theories regard space as just an aspect of time and that both exist as `quanta`. The problems are how we perceive those quanta, and apply them to normal everyday life. An electron isn’t really a classical solid particle, it’s only a probability; we can never know the `true` position and speed of the particle. When we describe space, we tend to describe a coordinate system in three dimensions. However, the universe probably consists of at least <b>10 </b>dimensions , with an extra dimension that has been isolated as a `temporal` dimension. It could be argued that ultimately all the dimensions are fundamentally the same. And that a spacial dimension cannot be divided indefinitely small, the limiting factor would be the quantum nature of space (10<sup>-33</sup>cm). This Planck length translates directly with the Planck-time quantum unit. A lot of people associate time with the flow of entropy; this is only a real- world product of the interaction of Feynman-Wheeler advancing and retarding waves. And how does Lynds` theory explain the direction of time? It doesn’t. Lynds only suggests that the lack of frozen static `instants` is what allows the universe to have time. Hum, The Feynman-Wheeler theory of time describes how every particle emits two opposite carrier waves; a `retarded` wave and an `advanced` wave. The waves travel `through` time; one forward and one backwards. It is the interaction (or absorbsion) with other temporal waves that give the particles a since of `movement` through time. When a particle absorbs a wave it also emits a retarded and advanced wave. In the original theory the density of the universe plays a critical part; in that, the retarded wave have to be (mostly) all absorbed by matter or else the interference amount drops. It has to be said that experiments to find advanced waves have found none. But perhaps the direction/absorbsion is decided by the boundary conditions of the universe; at one end there is the Big-bang (this reflects the wave) and the other end (future) is open (the wave cannot be reflected), and full of virtual particles. Are these waves present in our normal 3 spacial dimensions? They don’t appear to be. Maxwell’s electromagnetic wave equation permit forward and backward-in-time waves. We could assume that they cancel each other out in our `normal` space. But is it possible that these waves are actually travelling through compactified spacial dimension? These compactified dimensions could be like tiny `wormholes` that could connect to the future or past...This would allow a particle using its` retarded/advanced waves to propagate and interact/interfere with itself... Does that imply that the Time-dimension is only an illusion? So perhaps Lynd is right; time does not flow; because there is nothing too flow ; Time maybe only an illusion caused by the interaction/interference of opposite waves, travelling through compactified spacial dimensions. So what does that imply for the interaction of the 5 dimensional membranes that created the big-bang? Time could not exist in the same since that we would recognise; infact we could go as far to say that `time` did not exist `before` the big-bang. Time, and the arrow of time, was created at the big-bang event. Not a new idea i think ...If i remember paul Smart said some thing similar back in the 80`s....
