I love space and space travel. In fact, I have 2 websites on it, but I have to agree. As much as I love Star Trek, space is definitely not the "final" or "ultimate" frontier. The "heart" or "spirit" is it -- the most "important."
I think that the known and tangible world is not the end of all things. I believe that there is a spiritual existence, some people call it God, some call it energy or intuition. Everyone needs to define this non-tangible world for themselves but I feel for myself that there is an energy out there that always wants the best for me and that once my time on earth is over I will return back to the source of all being.
Wow! I didn't expect that! Thanks, Cyndi, for selecting my Hub for best answer. Your question was so timely since the Higgs Boson particle was just discovered by scientists yesterday. Then I saw your question and I just had to make a Hub about it.
