"the concept of moving between different moments in time in a manner analogous to moving between different points in space, either sending objects (or in some cases just information) backwards in time to a moment before the present, or sending objects forward from the present to the future without the need to experience the intervening period (at least not at the normal rate)"
But that's just the scientific definition of it...for me, time travel is just one way to go back to my past and change it.Well i might sound crazy but as a matter of fact, i am really interested in this.And i truly believes it is indeed possible.And i know a lot of you would have the same thoughts as me too right?Surely at one point in your life , you will think of something like "Hmm.. how good could it be if i could travel back to my past and change it".. or at least something similar to it i guess.
How good would that be if there is a possibilities to make that happen?Well, according to the law of physics,there are indeed possible!Theoretically at least =.= One of the way of doing so is .. through wormhole!Ok, due to my innate laziness nature ,i should just post part of the article in wikipedia here,
"
A proposed time-travel machine using a traversable wormhole would (hypothetically) work in the following way: One end of the wormhole is accelerated to some significant fraction of the speed of light, perhaps with some advanced propulsion system, and then brought back to the point of origin. Alternatively, another way is to take one entrance of the wormhole and move it to within the gravitational field of an object that has higher gravity than the other entrance, and then return it to a position near the other entrance.For both of these methods, time dilation causes the end of the wormhole that has been moved to have aged less than the stationary end, as seen by an external observer; however, time connects differently through the wormhole than outside it, so that synchronized clocks at either end of the wormhole will always remain synchronized as seen by an observer passing through the wormhole, no matter how the two ends move around.
This means that an observer entering the accelerated end would exit the stationary end when the stationary end was the same age that the accelerated end had been at the moment before entry; 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. This could provide an alternative explanation for Hawking's observation: a time machine will be built someday, but has not yet been built, so the tourists from the future cannot reach this far back in time."
There ya go = ] and here i attached this beautifully rendered picture of worm hole for those who are interested.
Actually ,i do have a theory of my own regarding this.Time is always constanly moving forward.Why is this so?I would say that time itself doesn't exist.Humanity creates time as a mean to define the constant motion of things around us.Think about it,what if everything stops moving?Everything is fix!Then there will be no more time.So thus, in the same theory,if everything were to be moved backwards,then we will all be back to the past.In other words.. degeneration of our mind and everything else.But if we were to do it this way,reversation as i would call it,then we won't be able to keep our present mentality intact....So i guess the only option left is building a time machine and go back?ARGGGGG screw it , i am writing nonsense! Where is the restart button in my life?

perhaps kicking the bucket would be the way to find out where ur restart button is :P
=P Theoretically i would suggest that:
Time traveling is possible.
But time altering isn't.
Like Newton's law. For every action there is an equal and opposite reaction. Considering that the system is closed. Then whatever you alter in the pass will hv an equal reaction which oppose ur action to change the future.
As a results you will still be ending up with the same future. =P
