I heard it say that light (or whatever) can travel faster than the speed of light by warping (folding) space and bringing the destination closer to my departure point. This does not sound right to me at all. If we travel along the folded space we would still traverse the entire length of the folded space geometry.
But does warping (folding) of space have anything to do with speed? IMO it is a function of relativity.
Example: I travel along a road toward a destination. This destination lies 60 miles away along a curved path, and as it happens the sum of the curves in the road actually brings me closer to my point of departure than the actual miles traveled, by half (30 miles as the crow flies). One could say that the road folded itself toward my destination. I travel this road @ 60 mph (fastest speed my car can travel) and it takes me an hour to reach a destination which actually lies only 30 miles away from my departure point (as the crow flies).
Now I create a shortcut, a straight road (as the crow flies), cutting directly toward my destination (cutting out all the curves along the path), and actually reducing the distance to be travelled by half. Thus @ 60 mph I arrive at my destination in half the time.
But this is not a result of folding space or speed, on the contrary, it is a result of creating a straight line shortcut toward the destination, bypassing the curves altogether.
When we create a travel plan, we often end up with directions which gives us a choice of routes, one being shorter but taking longer (by county roads restricting speed), one being longer but taking a shorter time (by freeway, maximum speed). Its all relative.
Any thoughts on this little visualization?
