This could be a question of particle physics, but I just want to see how much we know about this force yet? Any prospects of neutralizing it in the future or is it impossible to defy it? I think if we could figure this force out we would then be able to make manned interstellar travel a reality. Then by travelling to other planets orbiting other stars, we could have most likely found some form of life like our own(this is what astrobiologists believe), I mean life in the form of animals and humans probably, I don't mean going searching for life hidden deep beneath frozen oceans on other planets. So is this "interstellar travel" just a fantasy and dream or could it become a reality? Does it have anything to to do with gravity at all? We have all seen how magicians (like Chris Angel the mind freak) levitate objects, but that's just a trick. From a physics point of view, are we going to be able to someday completely neutralize gravity so that object could break free(like in free fall) from any sources of gravitational force? If we could attain that stage in our knowledge of our surroundings and nature, then I believe we could figure out where we came from by visiting other planets and see if there are other living humans/animals living there who could communicate with us? That's the question every human being I suppose should ask: Where did we come from???
