dimension multi-directional, it might have some relevance, but seeing as time moves in one direction, the video is simply some cool lines and graphics [/B]
Really.....this is a 4 dimensional projection on a 2 dimensional plan....
The sphere is 3 dimensions but the "energy source" for the projection is grouped with the sphere, because the sphere is the time-space projector. Just as time is considered the forth dimension, so can this undefined energy that is projected through the sphere.
IF we apply time to the plane, we don't necessarily have to consider it an additional dimension in this construct, we can consider time and space to be specific points on the 2 dimensional plane. The idea that people are referring to in this example is nothing new at all, by any stretch of the imagination. It is a variance on the old "fold a piece of paper over and poke a hole through it with a pencil" idea.
I thoroughly agree that time travel and travel to distant locations is not answered at all by any stretch of the imagination because this is only a souped up version of the old pencil through paper explanation of FTL. (Faster than light travel.)
Of course, this example is a tangible demonstration of an abstract process...this would require some sort of energy to pass through a device that plots time and space on an abstract construct...this process would somehow have to transfer matter to specific points on its abstract construct in order for FTL travel or time travel to occur....so, I can't see anyway that this would work because it wouldn't send energy to specific points...rather, it would send energy evenly distributed across all space time points or give an energy bias to a specific set of points when a spherical translation is performed on the projection.
Then this brings up another problem: .converting matter into energy and then converting that energy back into matter. That doesn't solve the problem of scattering that "energy" all over the place. In order for time space-time travel to work like this, the projection would have to be ridiculously precise. Maybe if the device is ultra complex, this "energy" would have to be projected again onto another projector which in turn is projector onto another projector and so on and so forth until you get a precise space-time point.
Still, this is very far fetched, under simplified, likely not going to aid in a solution, and is nothing new.
