I wish, sometime, humans would be able to develop the technology for us to build a spacecraft that can travel at warp speed (by warp speed, I mean travelling faster than the speed of light). And at the same time, the spacecraft should be able to open up a wormhole. All these will be made possible by an unknown energy, some kind of an "energy out of nothing" stuff which is so powerful that it would enable us to travel through the stars and parallel Universes. Imagine the possibilities. If in case what scientists present as a scenario where our Universe will end in ice actually happens billions of years from now, the spacecraft should be able to open up a wormhole and travel through it and exit in another parallel Universe. In order for the spacecraft to be really strong, I also hope that it would have some antigravity mechanisms and systems that would be able to protect it from warp travel and other hazards associated with such kind of activity, say, a system that generates a force field, shielding the spacecraft. That would be really something! Imagine the spacecraft entering into a wormhole, the wormhole's integrity being generated firm by the spacecraft, while it is being protected from any danger by the force field. How do we do this? How will we come up with these things? To tell you frankly, I have no idea.
