Forgive me, this is a really rough thought...

I've never really cared to know about other dimensions, possibly because I don't quite understand.

An idea I came up with the other night while trying to figure out a way around the E=mc^2 problem;

Which dimension does not have Time involved? Maybe it's impossible to go FTL in this dimension, but may be possible to 'shift' into another dimension where Time is not a problem.

Could there be a parallel dimension (where Time is stopped/doesn't exist) that we could 'shift' into.... travel from PointA to PointB.... then 'shift' back into whatever dimension this is?

Does this make sense?

Hi,

It may also be possible to shift into an other dimensional space, in which the physics allow FTL, regardless of the temporal dimension.

If we are ever able to SHIFT into 'other dimensional space' and survive, we will have to take our PHYSICS with us. FLT may exist in other universes, but we will never observe or experience it and survive. My opinion. Reasonable or not?

Suppose c in another universe were much greater than it is in our universe. We could pop into the other, go x parsecs at a greater speed than our original c but less than our new c, and then pop out again. Would we have travelled some distance in our original universe faster than light in our universe could have done it?

Hi selfadjoint

I would say the answer to your question depends upon the dimensional connectivity between the two universes. What are the topological, geometrical, and metric transformations between the two universes.

Sure. And in Tegmark's level 4 there will always be a universe satisfying whatever interface/boundary conditions are required. As Heinlein remarked in connection with a similar plot device (in "Waldo"), "Magic is loosed upon the world!

I think the only parallel universes or multiple universes are those that exist on the inside concave and those that exist on the external convex.

I think that EMRadiation actually travels faster than the observed speeds of EMRadiation by traveling on 5-fold icosahedral, geodesic pathways at speeds faster than EMR but is detected as if there were speed of radiation striaghlt line pathway i.e. you arrive at point B from point A a tteh same time either way but teh geodesic is tha longer pathway in order to be observed as our conventionally observed/recognized speeds it is has to to go faster than if it had traveled the straight line pathway.
