Time as a spacial dimention?

Question

Physics peeps, who claim to be able to mathematicly prove 11 dimentions, always seem to refer to time as related to but not the same as spacial dimentions. I have trouble accepting this.

If we are 3D, would we not at least pecieve the next (4th) direction in some extremely limmited way? Like, the way we do time. Could time not simply be the next higher direction of movement that we can not move through with any freedom, our sensing only it's most shallow (to use a lame 3D expression) surface?

Answer 1

Our temporal dimension is a spatial dimension, and people can live in any point of time. Each moment, we have a choice: yes or no, just as a computer each moment works with 0 and 1. People can travel in time back and forward, but usually they can't do it by themselves. Any person can be put in any point of time. That is why to live Z years is not to die Z years after birth. For example, you can live 20 years and then be put 2000 back or forward (for example, while sleeping, you even might not perseive that change, and if it was a desert, you might not perseive that you are 2000 years from the moment when you went to bed), and live there the rest days of your life. Altogether you can live 70 years, and die 2050 after birth or 2030 before birth.

Answer 2

Mathematically, we can have all of the dimensions we care to choose with just a stroke of the pencil. Interesting and intriguing, but it may not have any relevance to our universe or the way it is constructed or the way it really works.
Time is often considered the fourth dimension - it is indeed intertwined with space and runs at different rates depending on the gravitational field (i.e.the amount of distortion in the space). It dilates with acceleration and speeds approaching a significant percentage of light. We know of four dimensions, to be sure, and perhaps we are trapped inside this perception and cannot conceptional more. There certainly could be more - or maybe there isn't.
Even Einstein struggled with the results of his formulas - wondering if they were just a mathematical fluke or the way the universe actually works. Fortunately, he had the genius to determine they indeed represented the true workings of the universe.
Stay tuned, I'm sure we are ripe for the emergence of another "Einstein" and some more earth shattering discoveries.

Answer 3

movement? define movement without time. what is change? Can change exist without time? Our consciousness discriminates based on changes it perceives. No change, no perception, no consciousness. Hence it is unlikely that we will be able to rid ourselves of time as qualitatively different than the other (spatial) dimensions. We'd need to rewire ourselves dramatically. As for the 11 dimensions (or 12 or 24 or 9 or ...) they certainly do make some of the math more elegant. As yet they have not resulted in testable (falsifiable) predictions so they are what you should call "fantasy" at the current time. Proof of a fantasy, I'll leave up to others - its not science.

Answer 4

There could be 11 dimensions but they are so small we can't interact with them. The way I've come to understand multiple dimensions and their relationship with time is this: The speed of light which is a cosmic speed limit is tied with or shared with all of the spatial dimensions. Time as a dimension absorbs most of this "speed". But if you were to speed up along one direction or dimension, time would slow down at the same rate you increase your speed. The "speed" of light would shift away from the time dimension to the one spatial dimension you are traveling in. As you speed up time slows down.

I suggest you read "The Elegant Universe" by Brian Greene. It talks a lot about this stuff.

Answer 5

Consider your position right now. As a function it would look like

Me(time) = [time,X(time),Y(time),Z(time)]

This is 4-dimensions and movement along the 'time' axis is still distance.

Commonly, though, spatial dimension is concerned with where we are, not when we are.

Also, we may actually be 11-D, but only able to view the projection onto 3 dimensions.

Answer 6

We do (2) and we can (3) and we can not (4) but we do not accept it(1).
1)Example: Metaphysical the cold chill on the neck
2) Example: Time
3) Example: You feeling the motion of the universe
3) Example: Motion of a bacteria
With time and technology we will be able to observe but are limited by our current environmental laws of our fragile bodies

Answer 7

As tempting as that may sound, being of any deimension would not offer any guarantee of "at least perceiving" any other dimension.
Deriving mathematical explanations for anything is simply giving a language to observable or theoretical realities. That does not in itself prove anything.
I hope you become one of those people that can actually make some progress toward our understanding of these things. Good luck!

Answer 8

Well I've always seen space and time as linked. I mean after I took general relativity it was hard to ever go back to looking at them separately haha. But I can't speak on behalf of string theory and the 11+ dimensional worlds they work in.

Answer 9

Elastic collisions take position in the third spatial measurement. Electromagnetic sine waves are transverse to the route of propagation, so also they are known as transverse waves. Magnetic spin is in the Y axis and for this reason all 3 axes have one area of the flexibility move.

Answer 10

How do we measure spatial dimensions (length, width, depth)? In terms of time (how long it takes to get from point a to point b on a given linear dimension). So if time were a spatial dimension, our measurement would be circular or tautologous.
