For almost a century, scientists have been trying to figure out what’s good and what’s bad about Einstein’s vision of the universe. Blending the traditional view of physics with the bizarre almost impossible to understand world of quantum physics is no easy task – for anybody. It’s due to our current understanding of these phenomena that we believe it is possible to communicate instantly and to be in two places at once.The effort to unify the views has resulted in a stream of elaborate theories and ideas that mix together in a series of theories, of which the most notable is the string theory and its successor, M-theory. Actually, the M-theory unifies the five superstring theories and a type of supergravity. Recently, however, it seems there is a new variable to the equation; Itzhak Bars, a theoretical physicist at the University of Southern California, thinks these hypotheses are missing a crucial ingredient: an extra dimension of time.

So what we would have by adding a second dimension of time and a fourth dimension of space to the vision Einstein created, he came up with a new model that provides additional information that was previously impossible to find out. He claims this model could provide the answer to how nature works. A lofty goal, I would add. The thing is, physicists have never added a 2nd dimension to time because it opens the possibility of traveling back in time and (perhaps even more tricky than that) introduces negative probabilities and other things that would seem to be non sense. So could there actually be a 2nd dimension of time?

According to Bars, the answer would be “Yes, but only indirectly”. That means that we should think about the world as we know it as some shadows, which are seen differently from different perspectives.

“The predicted relations among the different shadows contain most of the information about the extra dimensions,” he explains.

The next step would be for him and his team to develop some tests in order to find out if their theory is right or not; and it’s exactly what they’re doing, and also adding gravity. If everything goes according to plan, this could mean adding two dimensions of time to the M-theory and finding the “answers” that have eluded us so far.

AlphonsePhenomena, not phenomenae. It’s Greek, not Latin, the plural of phenomenon.

danihelToday we think of the universe as 4 dimensional (3 spacial and the 4 being time) but actually the universe has six dimensions: the 3 spacial ones and 3 time for each of the dimension.

But this all just assumptions with no proof whatsoever to back it up. Future will prove it!

Rykerwhat about this, what if both dimensions of space and time go on for infinaty????? who says they can’t, it is also a proven fact that time stops at the speed of light. maybe the barier for the 2nd dimension of time is the speed of light, once you go faster than the speed of light, you break the time dimension barier and can time travel. even old albert einstien thoguht time travel was possible at the speed of light, i simply added onto why it might be possible.

GesnerbooksFor danihel: No, there are only four known dimensions but many more are suspected when exploring Quantum Physics and theory. Space and time are interconnected regardless of which of the three “space” dimensions you are refering to. All space is affected, even altered by time, and the reverse is also true. To say that each of the spacial dimensions has a separate time is simply incorrect. Also, there has been proof, measurable proof of this connection in print for many years now. If you really believe what you wrote, do not delve into Quantum Theory, as sub-atomic particle physics can leave brilliant men/women chasing mice in their collective heads. However, whatever you decide, keep reading.
