36grit Posted May 8, 2011 Share Posted May 8, 2011 (edited) It has recently come to my attention that space and time are not the same thing. So I'm wondering if time is an energy that occupies space? Does it eleminate the true vacuum of space? is it some kind of force field residing in and disrupting the true vacuum of space? If so does this field have an associated particle like all fields according quantum mechanics? Are length, width, and depth, dimensions relative to the time field density they occupy? Do you think virtual particles exist in virtual (nontime) space and that when they hit the surface of a timed space they draw together and pop like and air bubble coming out of a field of water? could the universe be described as a time field matrix existing in a nontime field vacuum that existed before the universe began? Is anti-time possible? Edited May 8, 2011 by 36grit Link to comment Share on other sites More sharing options...

36grit Posted May 8, 2011 Author Share Posted May 8, 2011 Time and energy are related. Energy is the conserved charge associated with time translation symmetry. I can imagine the time/energy relationship as it takes energy to move through space and moving objects have a slower time field than a body at rest. I don't think anybody really knows what time is but I'll predict it'll be the key ingrediant that prooves GLT. Link to comment Share on other sites More sharing options...
md65536 Posted May 8, 2011 Share Posted May 8, 2011 Unless you're speculating otherwise, spacetime usually consists of 3 spatial dimensions and 1 time dimension, so time and space are hard to compare. If you want to compare time to a 1D aspect of space, comparing time and spatial distance would be easier. Anti-time might be like anti-distance. I don't know how that'd be defined, but I'd expect it to only be abstract, not anything "real". Link to comment Share on other sites More sharing options...
ajb Posted May 9, 2011 Share Posted May 9, 2011 I can imagine the time/energy relationship as it takes energy to move through space and moving objects I tend to think of time simply as the conjugate variable of time. This is in the same way you should view momentum as being the conjugate variable to space. This means you can understand energy as a canonical coordinate, that is you can define the energy given theLagrangian of the system. You then see that special relativity does not allow us to make such a distinction between space and time and thus energy-momentum is the important thing. Conservation of energy is then due to invariance under time translations. Quite often time does not appear as an explicit variable in the theory and thus energy conservation follows directly. Anti-time might be like anti-distance. I have no idea what anti-time is. Other than it did appear in an Star trek: TNG and an audio episode of Dr Who. But lets for now try to keep within physics as best we can. Link to comment Share on other sites More sharing options...

In that neither one is defined, I agree. Both time and distance are abstractions, but for some reason time is the thing that trips people up.

lemur Posted May 9, 2011 Share Posted May 9, 2011 (edited) In that neither one is defined, I agree. Both time and distance are abstractions, but for some reason time is the thing that trips people up. Having two eyes allows most people to triangulate distance automatically in terms of perceived depth, which makes it seem less abstract. In a sense, the ability to store information as memory provides a subjective way of triangulating durations, but the fact you can remember things of many different time-spans would be comparable to having variable distance between your eyes for interpreting depth. Plus, you can remember something long ago without going through all memories of events between that one and the present, which is different from seeing depth where you must look beyond everything between you and the distant object and integrate everything into the same visual-field image. edit: as for time being a thing with the possibility of anti-time etc., why is it so hard to reduce physics to interactions of the four basic forces and then look at everything that emerges from those interactions as patterns that don't include any other entities than the forces themselves and their various configurations?

All buckets are filled with a constant stream of photons since the molecules comprising the bucket are always emitting some amount of energy, right?

michel123456 Posted May 9, 2011 Share Posted May 9, 2011 (edited) How does that demonstrate that it isn't an abstraction? Does a picture of a clock somehow show that time isn't an abstraction? Well, I disagree that time is an abstraction too, but i thought it was simpler to discuss distance first. It isn't. So for you distance & time are abstractions. from wiki: Distance is a numerical description of how far apart objects are. In physics or everyday discussion, distance may refer to a physical length, or an estimation based on other criteria (e.g. "two counties over"). In mathematics, a distance function or metric is a generalization of the concept of physical distance. A metric is a function that behaves according to a specific set of rules, and provides a concrete way of describing what it means for elements of some space to be "close to" or "far away from" each other. In most cases, "distance from A to B" is interchangeable with "distance between B and A". I suppose you are making your point on the "numerical description" while I speak about "how far apart objects are". I get the feeling it becomes argumentation without meaning.

I get the feeling it becomes argumentation without meaning. I think the point is that length/distance involves comparing things. To say that the distance between you and your broken down car is "two counties" requires an abstract process of comparing the size of a county to other indexes of distance. You can say the car exists, the road exists, that they're made up of matter with mass, etc. and those are all direct descriptions of actual physical things.

md65536 Posted May 9, 2011 Share Posted May 9, 2011 (edited) Since "anti-time" doesn't seem to be defined, you might define it as negative time, so that an equal duration of time and anti-time "annihilate" each other when added together. But time and distance are abstractions, as swanstont has pointed out, whether positive or negative. If you push 2 things together, you're not actually physically destroying anything as you reduce the distance to 0. Negative values of time and distance are useful for describing differences in the measurements. If you move something closer to me, my distance to it changes by a negative value. The difference between today and yesterday is -1 day. Meanwhile, the length or magnitude of any distance or time will be non-negative. It is probably easy to think of physical objects with lengths and events with durations, yet negative values may only come up when speaking of something relative to something else. So it might be easy to confuse distance as "something that is real", but it is only a measurement or a property of something real (or abstract).

Why do people have to confound truth with concreteness? It can be true to say that it is 100m from one end of a field to the other without distance being a concrete entity in physical reality? Yet it would be confounding to say that "100m" is as concrete as saying there are "one million blades of grass" on the same field. 100m might be more useful for various purposes, but it is still abstract whereas "one million blades of grass" could be less abstract but not as useful.

Nothing bad. The point raises when talking about time as an abstraction, as if it was something that is not part of reality. Some people argue that time does not properly exist, that time is simply a measurement or a human construct imprinted in our memory. I disagree with this point of vue. To me, time is part of reality, as distance is (meaning the fact that objects are far away or close to each other), or mass. Link to comment Share on other sites More sharing options...

The T-transformation and T-symmetry is already well studied (it does lead to some confusion to "non-physicists"). T-transformation is just time reversal [math]T: t \rightarrow -t[/math].

I would guess your disagreement with that view arises from the assumption that things abstracted from relations among physical objects are more objective than subjective abstractions that blatantly contradict empirical data. Surely, however, you can recognize the difference between directly observable "concrete" entities and abstractions that can only be explained/described through reasoning? Btw, is this a discussion that is going to take away from this thread? Link to comment Share on other sites More sharing options...
DevilSolution Posted May 10, 2011 Share Posted May 10, 2011 Time as we know it is only a perception of the change we see, we cant quite comprehend time as it is in truth. Time is relative to energy, if you like time can be seen as energy in as far as it cant exist without change and energy is the source of that change. Shame we dont quite know what Energy is.
