How little we have travelled

I often talk about how little we have travelled in space. The most we did (physically) is to reach the outer rings of our solar system with the Voyager spacecrafts. The spacecrafts are currently in the termination shock region of our solar system. Our Sun is one among the billions of stars in the milky way galaxy. They are billions of such galaxies in the universe. It will take quite a long time just to reach the next star let alone the next galaxy. Most of our research comes from telescopes that reach out to far reaching galaxies and get us great pictures. I find the prviate space program very interesting. I look forward to the space tourism launching next year. May be some day I will get to travel to the space. :)
