I have a problem with reversing "Time" dimension?

Question

if I was to reverse, would the "time" i'm in make me younger or would the time around me be only thing reversed? even though a theoretical 4th Dimension, equations can still be manipulated to comply, but would the conformation include me or just around me?

Answer 1

If you reversed time you would just enter a parallel universe where you would see the past but could not interact with it. You would see yourself at a younger age. Maybe ghosts are actually people from the future traveling back in time.

Answer 2

Please understand any answer you get that says or even hints at time travel in any direction is simply science fiction. Even those WAGs put out by the likes of Brian Greene ("The Elegant Universe") are infeasible scenarios (like worm hole travel). [See source.]

Time is somewhat an enigma, however. No one really knows how to handle it well. The best thought I've run across on time is that it is simply the marking of the natural entropic nature of our universe. Because the universe is in a state of increasing positive entropy, time marches invariably forward. This results because we cannot reverse the positive entropy rate of the universe.

By the way, the fourth dimension is not theoretical. It is a fact. To precisely locate any object, in our universe, we must specify x, y, z, and t coordinates (using Cartesian annotation). That t is the fourth dimension. You use t most every day when talking about the speed of something for example. When you say 60 mph, the h is the time dimension (hour).

Answer 3

If you were to reverse time, you would also become young as well and completely forget the fact that you reversed time in the first place, until, at which point your destiny would have you reversing time again (in an eternal loop), you would maybe have a sense of deja vu (or not, who knows).
You would have to create some sort of anti-time device that would comply to only you to make sure you could "travel" back in time, but that would be an extremely difficult device to create and, relatively, it would be impossible.

The fourth dimension IS time, so there goes that.

But time travel is completely impossible, thanks to physics and our enormous masses (called our bodies) that restrict us to time and its properties.
If you could somehow shrink yourself to the size of an atom (quantum level) you could possibly travel in time, as it is fairly common in the quantum world (some theories suggest the brain and its connections to the senses work in time-travel so that hen one touches something, one instantly feels it instead of feeling it ever so slightly later thanks to the time is takes for the reaction to travel from the finger to the brain. However these theories and tests have obvious errors in the processes)
But as I said before, time is impossible to control and you would not be able to choose in which time you would go.
You can see the past and the future however by viewing the earth from a distant planet with an impressive telescope and either accelerating toward the earth (to the see the future and catch the light rays sooner) or accelerating backward (to see the light rays later), but that would be fairly difficult as well to properly test.

In brief, you would go back in time (reverse-aging) but your memories would disappear too.

To expand, time is really only a human invention and time works for each and every person slightly differently. However we are each forced to abide by it's rules considering the fact it is impossible to go the speed of light (the speed required to move in time), in accordance to the laws set by Einstein.

Answer 4

You mean 5th dimention. We live in a 3d space and 1d time universe (4d's total). But that 5th dimention would'nt necessarely alter time. Then again it could, but we would'nt know because that universe is beyond ours and the mathematical variables needed to describe the physical laws of that universe are hidden to us.

ie: if we lived on a 2d space 1d time, or flat universe, even if that flat universe would be curved like on the surface of a cylender, we would not know what up and down is.

Time as we know it is unidirectional and is represented as frequency: f=1/t so you see time is "made of" frequencies (f), it is also part of space, which is "made of" distance (d) : as in how long it takes to get from point a to point b definded in : v=d/t.

In our universe time does slow down around massive objects like black holes, taking an angular momentum compared to ours. I don't think going backwards in time would make you younger though...The younger you is there howevver!

Also think about this: in order to reverse time has to slow down and stop completely, (at an angle of 90 degrees, momentum is back to ZERO!) how "long" would that stop last???

Steven Hawking has written a book called: A brief history of time in which he describes "anti-time" or immaginary time. A very interesting book!

Answer 5

time can't be reversed...even in physics it is impossible...it will go against the law of entropy....
