If we don't invent FTL ships, than Generation Ships are pretty much our next bet.
Generation ships would look cooler than an FTL ship anyway.
There are a few FTL methods left that don't violate causality completely, but at our current technology level I wouldn't consider FTL realistic. It would take large advancements in energy production at the very least to start considering some of the ideas, along with a better understanding of the fabric of space time. And maybe even more understanding of gravity.
As it stands the solar system is more than big enough for us right now.

Given the absolutely phenomenal size of the universe, travelling in it seems ridiculous, we've just about catalogued most things on this planet (And we're not even remotely close to completion), let alone our solar system - imagining the scope of the Universe is absolutely insane.
Space is big, yo.
I was expecting a star system with like more than 10 planets orbiting stably around the star, not a single planet orbiting far away from the star. It's like cheating.

And which are those?

[QUOTE=catbarf;49625510]Yeah, and shortening distance by some means instead of going faster than light is still a causality violation that contradicts general relativity.
There are lot of sci-fi tropes to justify FTL that are purely fictional, but people seem to mistake them for plausible theoretical mechanisms for cheating Einstein. It's entirely possible that relativity is as airtight as it appears to be, and exploring the galaxy will be done at sub-light speeds.[/QUOTE]
Not really. Distances are shortened all the time in the presence of mass without causality violation.

"theoretical technology" I have no idea about, since the ol negative energy thing comes up again.
I still like to believe in some form of FTL being possible, just for my own selfish sake to be honest. I still see the roadmap to the stars as D-T fusion > He3 fusion reactors+drives > even better drives/reactors > understanding of quantum gravity > who knows

also you never answered my question on your profile about figuring some hard maths out :c
Still trying to build an integrator for n-body simulations and I'm lost as all hell and wanted to show it to the professors of the plasma lab I'm hoping to work in as "hey look i can do things"
[sp]I figured you were busy with more important stuff tbh[/sp]

they haven't disproven wormholes, but they haven't shown how to generate one, let alone how to target one, otherwise i don't know of anything else that doesn't use exotic matter

i still think some sort of FTL has to be possible, but if one such technology did exist the fermi paradox basically smacks you in the face again because the galaxy should be populated by now with the first species to invent FTL which shouldn't be us
Damn, I wonder how long it's days are.

alcubierre drives, on the other hand.. it would be freaking awesome if we made those work.[/QUOTE]
no it isn't.
travelling at sub FTL speeds, humanity could colonize the galaxy in 20-30 million years which is a universal blink.
I was kind of expecting the Firefly star system, but I guess a million year orbit will do.
[QUOTE=HumanAbyss;49632749]no it isn't.

Of course everything would be heavily localized with no galaxy-spanning government. But ships traveling at 90% of C would be really damn fast and time dilation would be very helpful for the people on board.
