If you’ve this is one of a kind. heard of this particular theory. Please let me know as I’ve done some research (okay, a little googling) and have come up with nothing.If at any point in the future1(too the power of one), a method for backward time travel becomes possible, all points in time (both past and future points) will immediately have evidence of backward time travel. In other words, we would know backward time travel is possible today if it is ever discovered in the future.ofcourse this would not prove that time travel is physically impossible, since it might be that time travel is physically possible but that it is never in fact developed (or is cautiously never used) and even if it is developed, Hawking notes elsewhere: that time travel might only be possible in a region of spacetime that is warped in the right way, and that if we cannot create such a region until the future, then time travelers would not be able to travel back before that date, so This picture would create an explanation why we haven't been overrun by tourists from the future. The possibility that time travelers could be here, but are disguising their existence or are not recognized as time travelers, aliens perhaps.Einsteins Speacial Theory of relativity and by extension the General Theory very explicitly permits a kind of time dilation that would ordinarily be called time travel. Currently, traveling at the speed of light can cause time dilation, which cause the individual through time more slowly. For the traveler, external time would be going much faster, causing the traveler, upon stopping, to arrive at a place farther in the future.Time travel is the concept of traveling forward and backward to different points in time, much as we do through space.Unsolved problems in physics (paradox) Is time travel theoretically possible? Is it practically possible? If so, what are we to make of the time travel paradoxes, such as going back in time and killing one's own grandfather, Some theories are predicated on the fact that we move forward in time. Since time and space have been shown to be linked, travelling forwards and backwards through time is not a theoretical impossible.Other ramifications explored are change and reactions to it, parallel universes, and alternative history where some little event took place or didn't take place, but causes large changes in the future. If you were to go back in time to September 10 and prevent the world trade centre from collapsing you will have prevented that event in another universe's future. If you were to return to the universe it already happened in, it will still have occurred.There is no experimental evidence of time travel, and it is not even well understood whether (let alone how) the current physical theories permit any kind of time travel. Although theories do exist about the possibility of folding time to hop from one point to another. for example, if prior to entering the wormhole the observer noted that a clock at the accelerated end read a date of 2007 while a clock at the stationary end read 2012, then the observer would exit the stationary end when its clock also read 2007, a trip backwards in time as seen by other observers outside. One significant limitation of such a time machine is that it is only possible to go as far back in time as the initial creation of the machine, in essence, it is more of a path through time than it is a device that itself moves through time, and it would not allow the technology itself to be moved backwards in time.Proposed time-travel machine using a wormhole would (hypothetically) work something like this: A wormhole is created somehow. One end of the wormhole is accelerated to nearly the speed of light, perhaps with an advanced spaceship, and then brought back to the point of origin. Due to time dilation, the accelerated end of the wormhole has now experienced less subjective passage of time than the stationary end.Depending on one's perspective, so that a curved path through space can wind up being a curved path through time. In moderate degrees, this allows two straight lines of different length to connect the same points in space; in extreme degrees, theoretically, it could allow timelines to curve around in a circle and reconnect with their own past. For example An object that goes into the stationary end would come out of the other end in the past relative to the time when it enters.Creating a wormhole of a size useful for macroscopic spacecraft, keeping it stable, and moving one end of it around would require the existence of a substance known as exotic matter, or negative matter(",) which, while not known to be impossible, is also not known to exist in forms useful for wormhole construction and we will need significant energy, more than the Sun can produce in its lifetime.Therefore it is unlikely such a device will ever be constructed, even with highly advanced technology.Thank you for readingyou rock, you guys !
