Do you think man will ever advance to the point where Space will be explored?
Do you have any theories on how this will happen?
(punting off a satellite probe and seeing what happens in 20 years doesn't count)

Wormholes and warp drives— approaches to FTL flight — are theoretically possible, but the theory has not yet advanced to guide their construction. These theories are based on Einstein's theory of general relativity. The ongoing progress mostly focuses on the energy conditions — how to lower the energy required and how to create and apply the required "negative energy." One conclusion we have already found is that wormholes are more energy-efficient at creating FTL than warp drive. For more, see Eric Davis' “Faster-Than-Light Space Warps, Status and Next Steps” paper from last year's 48th AIAA/ASME/SAE/ASEE Joint Propulsion Conference & Exhibit.
The US National Aeronautics and Space Administration (NASA) is looking at a reimagined version of the controversial Alcubierre Drive to build a "faster-than-light" warp drive that can cut travel time to the nearest star to just weeks.
Physicist Harold White's design is based on an equation by physicist Miguel Alcubierre, who in his 1994 paper suggested a mechanism where space-time could be "warped" both in front of and behind a spacecraft.

Yes, but even at 100x light speed it would take around a decade to cross half the milky way, and by the time you got back with the time dilation on earth would be thousands of years past the departure date.
I would bet on the species becoming extinct first. There are probably tens of thousands of planets with life, yet as far as we know, none have visited earth. The universe is just too vast and travelling at anywhere near light speed would require a shield impossibly thick just to protect against radiation.
I'll be happy just to see space elevators.
me too they're my favorite theoretical technology
Humans are just an intermediate step between carbon based life and silicone based life.
There's a fair chance, if saner heads prevail that we will begin spreading out to new planets.
Just because of the sheer vastness of space, even leaving to the next closest star would take an unreasonable amount of time.
To travel great distances we would have to figure out either or both non-linear travel and non-linear communication.
Otherwise the time gap + time dilation would mean that anyone leaving would never return to anyone that they knew.... Or would require generational ships.
Silicone = fake boobies.
Silicon = computer chips.
Just sayin'...
wups. My bad.
OK, so fake boobies could have life too!
Considering there are ~2000 stars within 50 light years we shouldn't be too worried about that at this time.Yes, but even at 100x light speed it would take around a decade to cross half the milky way, and by the time you got back with the time dilation on earth would be thousands of years past the departure date.
There sure are times when it looks like they have a life of their own! :tongue4:wups. My bad.

Non-linear travel?
Wormholes or jump-drives as opposed to warp drive (Alcubierre) that actually moves 'through' the intervening space.Non-linear travel?
Depends on what you mean. In one sense, we've been exploring space for quite some time now. We've been to the Moon and spent quite a lot of time in orbit.
If you mean human bootprints on Mars, that's probably going to be another decade or two.
If you mean interstellar travel... that is extremely hard to speculate upon.
Conventional propulsion won't get it obviously.
We have one POSSIBLE method of sidestepping lightspeed, the Alcubierre Warp Drive theory... which was recently modified to reduce the energy requirements at least 10 fold, bringing it closer to the realm of the possible.
But we're still a long way from being able to engineer negative-energy densities. How far away?
No way to tell. Some budding supergenius might figure it out in the next few years... or it might take centuries of plodding scientific effort to get to that point... or it might turn out to be flat impossible.
Smart money says there IS a way.... but smart money also says it won't be easily or quickly made into reality either. :shrug:
