Is moving faster than speed of light a limitation that can be overcome in a higher dimension? Does it really require a lot of energy or is that only so under certain circumstances?
There is a lot we still don't know
Why would being able to move through higher dimensions help you travel faster through the 3 we're familiar with?
There is a 3D/4D equivalent, but it can't be visualized, and it's unknown whether it has any possible physical meaning.
This would be the coordinate system on a crumpled piece of paper analogy, yes? I can't help but feel this is highly unlikely.
Do we have any reason to believe this would be the case? Wouldn't we experience this crumpled space or is momentum crumpled as well?
Why would we expect new dimensions to be bent through our dimensions when the 3 we experience do not exhibit this behavior?
This is just an analogy anyway. My main point is, or what I hope science can figure out is whether the speed of light is a true limitation of reality or just a limitation of our own perception/understanding

This book covers all sorts of situations about objects in fewer and additional dimensions.
