Unbelievable to think it launched 9 years ago. Everything that's happened on earth whilst that small box has been travelling (just) to the outer reaches of our solar system and it's still effectively in our back garden. The emptiness of space boggles the mind.
This. What I'd like to know is what we will find when the very edge of space is reached. Any scientists want to hazard a guess at that one? In the same way that we now know the world aint flat, will we one day find out?
I understand that the reason we may never know is considered to be that space is expanding faster than you could travel to catch up. But expanding into what?
You can't reach the edge of space - if you could, there would be an absolute position in space, from which you could have absolute velocity and absolute acceleration, all in contravention of Einstein's two relativity theories.

This article is very interesting and a good summary of what's been found so far:
