Ah, fond memories of A Wrinkle in Time by Madeleine L’Engle.

folding the paper isnt enough. you also need to reform the paper to make the hole attach at both ends. ripping apart spacetime may not even be possible.

What if your neighbor wants to bend space time in the other direction?

Sure, it would take an enormous amount of energy to do it though.

Oh yeah, and you'd also be annihilated as you were completely turned to energy as you tried to go through it of course. But you'd sure fire a hell of a lot of randomized high energy particles out the other side after the amount of time it would have taken light to get there.

Not my preferred kind of "travel", I'll just freeze myself and go the slow way or something.

This common desire for FTL should be an object lesson in how wishful thinking distorts objectivity. We see a constant stream of ideas that spring from simply not understanding the domain of a function. You can put a negative value into mass or energy. That doesn't mean it means anything.

There really is no plausible theory for FTL of any kind. Maybe there will be in the future. Personally I'd put everything I have on the speed of light being an absolute limit to causality.

Look at it this way: if FTL travel were possible we probably wouldn't exist. Whoever came first would probably colonize the Universe and sterilize it of competition. So there's that.
