Is Time Travel Just a Concept?

[bozo the clown]

time is simply a perception motion. Time is not another dimension.
If everything in the universe came to a complete stand still i.e. no motion what so ever you could could still measure x to y but how would you measure time it becomes non existent until motion happens again than between no motion and motion we would percieve time.

 

[sarephina]

freezing of all motion. absolute zero. we haven't been able to achieve that yet. i wonder if time would stop if we did.

 

[Halitosis Crunch]

If all motion were to freeze would'nt that, to some extent, effectively support the concept of time being a tangible dimension? Of course, this would be irrelevant, since we could no longer pursue the concept in absolute zero!

Just in the fact that matter changes over the course of what we percieve as "time", suggests the concept. This is all relativistic. We can interchange length, height, and width to essentially be one another. The only thing that sets these dimensions apart is our relative position of observation.
So time becomes just the same. It's viewed differently in relation to our respective points in space.
We "travel" through time every day. It's a matter of acceleration/deceleration that affects our points in space/time.

This is a pretty good insight. There are still in general relativity some distinctions between time and space, but they're much weaker and more contingent than most people would believe. You can do surprising things with coordinate transformations.

The main distinction is that there is a sign difference between the time and the space coordinates. Either time is negative and the three space coordinates positive, or vice versa. Either way is OK, as long as you stay with it consistently in the math. The fact of this means that sometimes "four-dimensional length" aka "separation" can be zero, if the time coordinate exactly balances the three-dimensional space length. This is called a null separation, and the paths that light takes are always null paths.

This is called a null separation, and the paths that light takes are always null paths.

UNtil they interact with something else? ex: graviton

 

[automaton]

if e is variable ie" faster than speed of light" what happens to

TIME :surprise:
if some theories of light are saying light can be faster than einsteinian constant

how would this mathematically for example affect time
given time as function of e
new constants and variables yield new theories

Where I can find an open windows so i can travell to the future

I know is way to travell into the future I just to bussy into my regular life that i can't see it.

I will give away all i am, if i have the chance to travell into the future and find the anwsers; that all are we looking for.

This is my destiny, my real reason for my to exist

Any one helps or suggestions are wellcome to me...!

[seefor]

What about the TELEPATHING ?? is there any thing that be achived lately apoun human or any other organisms that breath?

 

[Chronos]

Can't achieve absolute zero in the quantum model. Perhaps in the thermodynamic model. The fact we can get so tantalizingly close parallels how tantalizingly close we can get to accelerating elementary particles to the speed of light. 'Freezing' an electron in it's atomic orbit is equally forbidden. We can extract nearly every bit of energy from any system, just not the very last bit of it.

 

[automaton]

is anyone familiar with superluminal theory

"faster than the speed of light"
a book
details light traveling faster than einsteins c
im sure others are aware of it :zzz:

:surprise: anyone

4)If it were possible to travel in time, THERE WOULD BE time travellers all over the place. Because there are not that means either every sentient being is afraid of time travel to do it, or because it is impossible to begin with anyways.

Perhaps humans don't survive as a species long enough to learn time travel. Maybe there's intelligent life elsewhere in the universe that has discovered a method of time travel, and has simply has not visited this neck of the universe.

 

[Chronos]

Time travel violates causality. Not to mention that law that forbids creating or destroying matter and energy. If you 'left' this universe you would be in violation. The only way to pull off that crime would be to hide enough 'negative' energy in your suitcase to exactly offset the positive energy you stole. Probably be hard to smuggle that through customs.
