What makes you think such things are possible? Is there any evidence for them? They seem like pure science fiction to me. As long as we are imagining science fiction, why not say we need instantaneous "beam me down" teleportation like in Star Trek? Or faster-than-light travel. Either one would save time on the trip. I see no point in saying "we need" things which do not exist as far as anyone knows.
