in 4d space could there be 2d time?

Question

and an object could travell in two directions at the same time.
Electrons seem to do that.
If we lived in 2d space we would have no idea what up and down is, mabe our unidirectional time limits us and we have no idea what travelling in two directions at the same time is.
What do you think?

Lxgwar or whatever your name is.
I know that, I mentionned it specifically
3 dimentions of space and one of time is 4d

I'M TALKING ABOUT 6D HERE YOU PRESUMPTUOUS POUMPOUS PERSON YOU!
6D (4 SPACE AND 2 TIME)

P.S. that comment was to lx_gwar_x

Don K you sound smart but:

1) electrons seem to travell in two directions at the same time!

2) if we lived in 2d space, even on a round surface we would have no idea what up and down is.

3) I'm sorry but you dont have enough immagination to grasp abstract concepts...

Science guy: I always hold your answers in high respect. Thank you.

Physics Dude, oops, I'm sorry I called you Science guy...My mistake.I have high respect for both of you.

Ted, I hear you. But why not have fun immagining things?
2d time is unimaginable to us in our unilateral time. Wy would it not be possible? We could live forever!?

Answer 1

Certainly we can say that it is possible, but a universe with two orthogonal dimension of time would be very mixed up since you can choose to be going forward in one time dimension but not the other, or be moving in both time dimensions. Perhaps this would also allow you to travel backwards in time, as long as you're going forward in the other?

Thanks for sharing such an interesting idea.

Answer 2

I'll commit for each.

"and an object could travell in two directions at the same time.
Electrons seem to do that. "

Not that I remember, Electrons move one direction at a time. They at times stop and go the other way but never both at the same time.

"If we lived in 2d space we would have no idea what up and down is, "

Yes we would know what up and down was or even length or with. But would not know there was a mass. Every thing would be flat up or down or left and right.

"mabe our unidirectional time limits us and we have no idea what travelling in two directions at the same time is."

Now that is a fair statement.

However, there is a way of seeing this. Just not put in to a theory on any scientific level yet. Well not that I know of, When two people are standing side by side or born as twins, and both are telepathy connected one can go to Asia and one to Africa and see what each other is seeing and feel the same things and know what each other knows. Then you would have found your forth dimension. Anything that splits and moves away form the other can not live. So mater as a human or pure energy would die split.

Answer 3

No, there could not be two dimensional time. We define "time" in such ways that it can only be one dimension.

Spacetime is four dimensional. We just happen to call one of them time because it is the direction in which things move in order to get from now until later.

If there were eleven dimensions, we would still pick one of them as the time dimension.

So "time" is not determined by properties of a dimension that can be given to two dimensions simultaneously. "Time" is always the dimension that we move in to go from "now" to "later."

A simplification of quantum mechanics says that photons (and electrons and other fundamental particles) "travel" in two dimensions at the same time. When there are two slits, if we send a stream of light through it, we see an interference pattern. However, if we send a single photon, we figure that the photon will not have anything to interfere with so it won't land according to the interference pattern; instead, we figure it will somehow "pick" a slit and land directly ahead of it. However, each single photon DOES land according to the interference pattern. So the suggestion is that the photon travels through "both" slits and interferes with "itself." This is a simplification. Each photon carries with it a probability distribution which represents the possible locations it may be at a particular time of observation. It is this probability distribution which "travels" multiple paths and interferes with itself. The photon then "pops into" existence according to the probability distribution after the distribution has spread out.

So there is no "traveling in two ways at once."

Additionally, there is no "time particle" to travel multiple "time dimensions."

So I think the question is the result of lots of oversimplifications that were originally meant to help understanding but are probably hindering it now.

Answer 4

What's your motivation for this question? I happen to feel there's some legitimacy to it.

I'd call is 2-degrees of freedom rather than 2-dimensions, or perhaps polarized.

Answer 5

I agree with PhysicsDude. This could absolutely be possible, pending further investigation, both theoretically and experimentally.

Answer 6

No, because the forth dimension is time. That's when Einstein said everything is relative.
