5th Dimension theory

[Ken2535]

No one knows exactly what the 5th dimension is.
1. a line
2. A flat object(width and hight)
3. Width hight and depth
4. Time itself
and what i think is that the 5th dimension is Time Travil

Does anyone beleave my theory?

[Tormod]

What theory?

[Becca]

We will probably never know much about any of those higher dimensions because we can't perceive them in any way that we can with the others. I don't think time travel would be a dimension though, it's a movement through some or all of the others.

If you want a physical dimension the math is explicit and trivially manipulated. If you want compactified dimensions you have one charge dimension, two isospin dimensions, and three color dimensions atop the usual three plus time. Their physical meaning is debatable. If you want to play games like Heinlein's Number of the Beast you have three space axes (x,y,z) and three time axes (t, tau, teh). Time travel violates causality. The universe does not tolerate contradictions.

You cannot expect an answer of any better quality than that of the question you ask.

UncleAl, your reply is perfect. Time travel violates causality. Eisten has theoritically proved its practical impossibility. Well, I have heard about the three time axes (t, tau, teh)... never understood though. Also I have heard about theories that has more dimensions. Say M-theory that has 11 dimensions defined. Are these theories proven? Can you throw some light on this.

Time travel violates causality only if you think there is only one version of reality. If you think that quantum theory should be taken literally then time travel does become possible. When you go back in time you would start a new time line separate from the one you were in before you went back. In fact you have instantly created a new time line separate from the other. In the old you never went back in time, in the new one you did. This of course would set the stage for even more time lines as you move around and disturb the new time into separate time lines. It just depends on whether or not you take your quantum mechanics straight or mix it with parallel worlds.

ooo, ooo, ooo I know, I know! The fifth dimension is what ever is at right angles from the forth dimension!
No really, there is no reason to say there cannot be a fifth dimension and time is an illusion we create to help us see the infinite number of three dimensional moments in 4D space time. The fourth dimension is simply what is at right angles from the third. But time is a good way to think of the fourth dimension and the fifth would allow for an infinite number of four dimensional space times as the fourth allows for a infinite number of three dimensional moments in time. It's so easy when you are as uninformed as I am Actually there are many ways to look at the extra dimensions but I like the brane theory types my self. Curling dimensions up into infinitely small regions or tubes or whatever can still be done inside the bigger spatial dimensions. I can work this out to ten or eleven dimensions but the they all have the similar effects. If you like to think of time as the fourth dimension them the fifth would be similar to the fourth dimension as the fourth is to the three we are completely aware of.

One way to look at the fifth dimension is connected to two different space-time references interacting. The more contracted reference sees things different in space and time. If we didn't know it was in another reference, but it was interacting with our reference, the affects would appear to be off in terms of cause and affect in our reference. For example, time dilation within the fast reference makes a person appear to age slower. If we didn't know he was in a fast reference, but assumed he was in our reference, it would appear like he had new virtual biology. If one is aware of the reference difference, and can compensate for these differences, the fifth dimension can be factored out.

It is possible we are not fully aware of all reference interactions since high GR is different than low GR. While, by convention, we only use the zero reference to coordinate universe gravity. If there was reference interaction this assumption may create anomalies needing the 5th D.

Tell me what you have perceived that leads you to believe that the first three spatial dimensions are real physical things? After you answer that then we can proceed to talking about the dimensions beyond that.

Read post #9. Same goes for you. What makes you think the first three spatial dimensions are physical things?
