This is something that is more or less 20-30 years off in the future. The nature of medicine and healing is changing. Think of right now as being like the Dark Ages of medicine, we’re in a barbaric state of medicine, treatment and surgery. The future of medicine and healing is going to be through light. I see treatment taking places from certain frequencies of light that will stimulate healing, stop cancer growth and etc. I also see treatment’s regarding medication being like antibodies that are genetically created that are almost like an organic type of robotics.
Space travel like we see on Star Trek will never occur. The secret to Space Travel is through wormholes, dimensional traveling and so on. The future space crafts will also run from water. It will be possible to travel throughout the Universe through these dimensions, portals and even to access other dimensions.
