Thread: Energy to move through time dimension.

1. Energy to move through time dimension.

It takes energy for an object to move within the spacial dimensions, but does it require energy to move within the dimension of time? If not, what makes the time dimension different than the others?

Move with respect to what? It takes energy only to accelerate with respect to another object ... but not to move.

3. Re: Energy to move through time dimension.

Anyway, what does that mean, "to move within the dimension of time"? *When* would one do that?

To move is, essentially, to be in different locations (and/or orientations/configurations) in space at different points in time (in some frame of reference). It necessarily involves both, and amounts to a correlation between the two.

Well consider the original grandfather clock and consider the universe as an infinite source of energy if you want to put it that way. Now because of space and entropy You can either go to another dimension or stay in the one your in. Being reborn isn't that bad. However don't bees pollinate trees? OF course dimensional travel will always be possible whether or not it's our own time we're in.

5. Re: Energy to move through time dimension.

I truly believe that in order to move through another dimension and or to travel through time you must be pure energy. I honestly believe this also. In some universe there may be a way to find wormholes or tachyons to also achieve this. When we find ways to convert mass into "pure energy" and than reverse the process I think it will be easier for us to mess with dimensions and the space time continuum.

6. Re: Energy to move through time dimension.

To the first question: Yes it does. Time is just another "spatial" dimension, Minkowski, 1908. Second question: We appear to be passing through "time" while we appear to reside within "space". This makes time appear to be directional. We usually confuse this with being "linear" (time line). "Space" without "time" is an illusion. There is no "when" only where. Just as we cannot have a truly "flat surface" in three dimensions we cannot have only "depth" to "space" in four. In application, objective reality, there is no "straight" line without width, depth and duration. There is no "flat" plane without depth and duration. There is no "depth" to space without duration.
Duration ("time") is never linear, but four dimensional. It has length, width, depth, and duration everywhere, everywhen within our universe as we know it. It is "hyper-space" all at once. We have names for circle and square in a plane, sphere and cube in a space, but then we revert to hyper-sphere and hyper-cube in hyper-space, in a time. It is mostly our lack of language for it that is confusing. That it seems different is a positionally generated illusion. From where we are it just appears different.

We cant move backwards in time any more than we can move backwards in space.
Our perception of local space time is related to other observers perception of space time per the rules provided in SR/GR

That ratio can never produce a way to travel back in time either locally or relatively.

We can't move foreward in time anymore than we can move foreward in space, or any less. If we move in one, we move in the other. They are inseparable. If we assign X,Y,&Z a positive relationship then ct is negative, but positive and negative assignments to X,Y,&Z are arbitrary. We may always be moving backward in time. No matter what the direction it requires energy.
