We don't even have the technology to escape the sun's gravity without needing a gravitational slingshot from other planets, and that still leaves us with a space craft moving slower than the earth.

Nitpicky but.... we'd still want to use gravitational slingshots even if we had more deltaVs to burn.

#4Um, what about Voyager 6? I'm worried...

Problem is we don't really know where to go next. Jeff Bezos' Blue Origin tried to cook up alternate space travel methods for years and still couldn't come up with anything better than the same basic rocket model that put Gagarin into space.
Most theorized "warp drives" either require more energy than humanity is capable of producing or necessitate breaking a law of physics or two just to move anything organic or larger than a postage stamp.
Then again, the answer could be right under our noses. There's a Sci-fi story - I forget the name - where space travel is actually quite simple if you know the math to make it happen, and when a peaceful alien race visits Earth, the humans - with their thousands of years of armed conflict - kill the aliens and take their spaceships.
Makes me wonder that if we treat the rest of the universe the way we have treated our planet, do we truly deserve the right to roam the stars?

#7Would be really cool to stick some velocity numbers on there as well, I find it hard to relate to such huge distances. 62 thousand kilometres per hour feels larger because I can kind of comprehend it.
Though really cool anyway, I was going to say that Voyager 1 managed short of 30 light seconds a year until I realised the question is one of acceleration and deceleration not velocity. If I wasn't on my way to bed I would dig around for some data to make acceleration graphs for them (hint hint :P ).

Indeed, only 59 years since we first put something into earth orbit.
We're just getting warmed up!

It would be nice, and is certainly the result I hope for (with all the good wishes do), as I'm not sure we will work very well with slow and expensive growth. Reading 'Against a Dark Background' was certainly interesting as it considers a system which essentially has its growth capped by the distance between itself and the rest of the universe.
