Physics involving time travel



Did you know that some peoplle think that by harnessing the power of ohotons and electrons (wich travel faster than the speed of light) you can travel forwards and backwards in time.
Regular Beer has more alcohol than lite beer, therefore, the weight of a sixpack of 'standard' beer is lighter than a sixpack of lite beer.

So when subjected to acceleration, regular beer is faster than lite.

Note also that alcohol is a time altering substance, drink enough and you won't even know what day it is.

Excuse me a moment while I attempt to 'get a life'. Bye.
Maybe, However using energy like light (photons) or elctrons may not be the only way. There are many theroys invoving wormholes or just plain rips in time. Did you ever see the movie the "Langoliers"?
As suggested by others, Perhaps we need to look at the definition of 'spacetime'. Spacetime is a geometry that includes the three spatial dimensions and a fourth dimension of time. In Newtonian physics, space and time are considered as separate entities and whether or not events are simultaneous is a matter that is regarded as obvious to any competent observer. In Einstein's concept of the physical universe, based on a system of geometry devised by H. Minkowski, space and time are regarded as entwined, so that two observers in relative motion could disagree regarding the simultaneity of distant events. In Minkowski's geometry, an event is identified by a world point in a four-dimensional continuum.

Minkowski geometry unifies Euclidean three dimensional space plus time (the "fourth dimension") in Einstein's theory of special relativity.

OK bear with my spelling please.

If I recall there has been some talk about tyceons and there effect on the speed of light such as that the spead of light has a relationship with that of tyceons and the concentration in a particular area. As such a sphere of them may allow a object propeled at the speed of light inside the sphere to travel fast that light out side said sphere. Now since beyond light speed time dillusion is believed to go into the negative than it is possible that the object would go back in time while not be effected by its travel. Thus while back my be possible forward may not be.
In short physics invloving beyond light speed phenomenon is what should be looked at to get a theroy out about time reversal.

Out of interest does the univers and all planets spin in the same direction?
