content: I chose the title because I enjoy discussion In terms of size, we are very small, very small indeed, and we are only just seeing planets outside our solar system that could potentially support human life. That said, our fastest space vehicle would take approx 180,000 years to reach a star 4 light years away, that's 90 times the length of Christianity (for want of a better measure). Any signals our craft sent back would take 4 yrs to be received by earth, and an additional 4 yrs for our craft to receive a reply. Just think about it, 180,000 years...could humans in that craft even remember that Earth existed, apart from a myth, a fairy tale. How would humans evolve in that time both in the craft and on Earth? Would humans even exist on earth after 180,000 years? I posted this because few, if any, can actually comprehend the SIZE of space. I know I cannot
