Which is why we need to work on the aging problem. Once that is solved, we can explore all we want.

We've already solved that with reproduction. We need to figure out how to out-live our planet.

No, not exactly. We still dont know if we are able to give healthy births with no or less gravitation.

Correction: laws of physics as we currently understand them For example, we still don't understand inertia and gravity. Nothing is impossible.

This is what I like to refer to as the "bias of computing." The idea is that we deal with so much scientific progress in our fields that we tend to think that scientific progress can take us anywhere and no restriction will stand up for long. However, this is a fallacy that really has no grounding in the laws of physics. What reason do we have for thinking that information can travel faster than the speed of light? M…

But if we never dreamed it so, then we never would have tried and never would have broken down those other barriers. Just the fact that we've broken down all those other barriers inspires me to believe.

Reproduction doesn't address the aging problem at all. To quote Woody Allen, "I don't want to achieve immortality through my work. I want to achieve immortality by not dying.". The same thing applies to reproduction: I don't want to achieve "immortality" of some fraction of my genetic code, I want to achieve immortality by not dying. :)

Agreed. Aubrey de Grey is a crazy bugger, but he's got the right idea.

I think he has a good chance of finding ways to slow down the aging process and buy us some time, just like we've managed to extend lifespans heavily through other advances in medical and related technology. However, I have very low confidence that that direction of research will manage to completely solve the problem. We have far too many ways of breaking down, and not all of them seem solvable by patching. I have somewhat more hope for a solution from the AI camp, personally. I just hope the Uncomfortable Truths Well (http://xkcd.com/568/) doesn't prove correct.

I think predetermining that faster-than-light information transmission is possible is a bastardization of scientific progress. I don't see physics as a quest to break barriers, I see it as a quest to understand the nature of the universe. If the nature of the universe is that humanity will never colonize another world in a lifetime, then so be it. We simply have to learn to deal with the realities of our existence.

For anyone who didn't get the 'joke' (like me) and who knows nothing about Star Trek (also me), turns out that "V'Ger" is a Star Trek character. From Wikipedia: "A sentient being that evolved from Voyager 6, a fictitious space probe from the 20th Century that vanished into a black hole and was given life by a race of living machines. The story of V'ger and its return to Earth to seek "the creator" forms the plot for…

I'm personally waiting for V-GINY.

It must suck to create a new account, just to have your first comment failguy out and render your account useless. Won't the auto-kill feature just automatically deaden any future posts from this guy? Seems like a poor way to nurture possible good HNizens who make a mistake or two in the beginning.

Technically he was only following the example of the V'Ger guy who isn't being downvoted.

It's almost as if the universe was created to mock us. So much space to explore, but physical law makes it impossible to explore more than the smallest, most insignificant fraction.

Correction: laws of physics as we currently understand them For example, we still don't understand inertia and gravity. Nothing is impossible.

Funny you should try to imply that our fundamental physics are somehow wrong in a serious way that we have a high chance of finding a deeper physics that shows "impossible" things by today's physics are possible (want to take bets on timeframes?), on an article about two space probes that have lasted 34 years out there because of our understanding of the fundamental laws. As for not understanding the "why" of inertia and gravity, we nevertheless have general relativity which is pretty darn good.

I'm so proud of Humanity right now. Thousands of years later when future Historians would be studying our period, I am sure they will feel proud about the far-sighted decision this Voyager project had been. Future scientist may thank us for setting a benchmark they now have to excel.

nothing to replace it? See SpaceX and Virgin Galactic.

SpaceX in a few more years should be able to do human transportation to orbit. Virgin Galactic is for space tourism and doen't fulfill any of the roles the shuttles were used for. When the shuttle retires, there really isn't anything else (in the US) that comes close to replacing it.

Why should SpaceX be the only competitor who succeeds in the next few years?

It just so happens I was listening to some beautiful 1970s space music when I read this (Tangerine Dream, if you're interested). The dreams of exploration we had from the time of the first man in space through the 1980s were so wonderful and optimistic. I grew up reading OMNI and Discover, watching Carl Sagan on television and playing with toy Space Shuttles. When the Voyager left earth, we believed that man would wa…
