Another thing to ponder about: do you think humans will ever be able to travel at the speed of lite or faster? If there is life out there, the only way i see us contacting them would be to travel this fast at least.
You're thinking too inside-the-box. There no reason to necessarily assume that we have to work within the boundaries of space and time as we know it. Even if we ever did figure out a way to travel at C (or faster), a current mathematical impossibility, it would still be a horrible way to travel. Even at the speed of light, you would basically say goodbye to everything you know for a trip to the closest star. At exactly the speed of light, you would notice no passage of time, but when you made the round trip to there and back to earth, nine years would have passed. Now imagine going to some of the more interesting places -- some hundreds, or thousands, of light-years away. By the time you GET there, nothing on Earth would be the same. And it would take as long to communicate back as it did to travel. Just thinking about those practical limitations makes traveling at the speed of light unappealing for stellar distances. Going to, say, Saturn, would be one thing. But all the way out to another system? Nah.
You need to forget what you think you know about classical mechanics for a little while, and start pondering the possibilities of theoretical physics. For example, there's a notion in quantum mechanics that states that one particle can exist in two places at once. That is, that particle exists in spacetime just like you and I, but it only shares the time portion, not the space. So when a force acts on that particle at one location in space, the very same particle, perhaps on the other side of the universe, would react the same way. There's your form of instant communication.
Physics is getting closer to the understanding that the universe, matter, space, and time are all illusions built up upon each other. There's so much we don't know that to limit ourselves to what we do know seems short-sighted. Of course, we don't know what we don't know, but we won't know it until we start looking.
