[QUOTE="Umbran, post: 7547148, member: 177"] I can't say that something is *impossible*. But, to be frank, it is not "fantasy" to think that there are limits. Warping space requires energies on par with the mass-energy of a thing that would produce similar warping. Individuals carrying around a power-pack equivalent to the mass-energy of mountains and small planets? Highly unlikely. The darned thing would be prone to collapse into a singularity. It annoys my wife when she loses a lipstick in the bottom of her purse. Losing it down a black hole? Not an improvement :p But then, interstellar travel is itself highly unlikely, so the finding lost civilizations and meeting extant ones? Similarly unlikely. In the past (like, when Flash Gordon was first a comic series), we thought of flying cars, flying belts, death rays, and all - all of these things required revolutions in *energy* to make happen. And none of them did, because we didn't get an evolution in energy, we got a revolution of *data*. And there's probably physical reasons for that. The energy densities available to beings made of normal matter are... limited. [/QUOTE]
