As a result of discussion on the "Picking on Einstein" Thread, who here thinks that super-luminal speeds (speeds faster than light) can be acheived.

Please give an explanation for your decision if possible.

[AntonioLao]

this is revisiting Zeno's paradox but from a modern perspective. Given two points of the same spatial dimension, the maximum travel speed is ~300,000 km per second but if the two points are of different spatial dimensions, say one is 3D and the other is 5D, then the speed needed must be superluminal.

So, we can say that superluminal speed is what is needed to travel between different dimensions. To travel back in time is to travel to a lower dimension and to travel forward into the future is to travel into a higher dimension.

On second thought, could it be a sub-subluminal (no motion or absolute rest) that is needed to travel back in time?

[Guille]

I think superluminal speeds are possible but it would imply no having mass or transfering information. This is still now a days, impossible for humans. But I also think that maybe future discoveries show mechanical works that can alter these rules on light's speed and go faster than it.

Antonio,

what do you mean that going back in time would be differen than going forward in time. Both are the same dimension, but just the two different ways.

Yes. We are all imprisoned within this one dimension of time. Breaking the light barrier is the same as saying ripping or tearing the spacetime fabric into a wormhole, which is also breaking the dimensional barrier of spacetime and we already know that superstring is 11th dimensional and it can predict the existence of gravitons. Theoretically, gravitons are known to break the spacetime barrier into different levels of dimensions. The most logical superluminal objects are the gravitons with intrinsic spin equals 2.

[Guille]

do you mean that gravitons go faster than light? doesn't gravity disperce in a no-speed way? I mean inmideatly? that's what I had understood when reading Einstein...

Yes. Graviton can tear or cut or rip the spacetime fabric which nothing else can. It intrinsic spin is 2.

[Guille]

do they then go back in time? I think I already wrote this, but, is gravity going back in time? I meant aht the gravity things create now, it is the gravity it will create in a millions or billlions of years?

[AntonioLao]

If graviton has an anti-partner, the anti-graviton then one travels backward and the other travels forward in time.

what does charge have to do with time?

and, wich one would go forward and wich one would go backwards in time?

[AntonioLao]

the photon is considered as its own antiparticle. "anti" does not mean only opposite electric charge. The neutrinos have their antiparticles and neutrinos have no electric charges. But there are properties of weak charge and color charge and also helicity that can be used to differentiate particle and antiparticle.
