How might intergalactic travel be accomplished?

Any ideas, other than wormholes or hyperspace?

You pretty much excluded the two major possibilities. The primary issue is the massive distances involved. With this in mind, the only way to effectively travel is by either bypassing the normal restrictions on acceleration and velocity via some kind of warp or hyperspace travel, or by effectively shortening the distance you need to go, most likely via some form of controllable wormhole.

There is always the possibility of an ARK ship. You would travel the full distance at sublight speeds, with each trip taking as long as several centuries. If we can't figure out some kind of safe stasis or cryo storage, it would likely be the descendants of the original voyagers that disembark. But this method does us little good. We might be able to establish colonies this way, but would not be able to trade with, assist, or even effectively communicate with them (imagine waiting 55 years on a request you sent in for a status update, or perhaps getting to listen to the screams of the dying colonists as a disaster that was long over several decades ago plays out).

We could always pray for divine intervention. If we pray hard enough God will fix it for us.

Intergalactic travel involves distances of millions of lightyears. Even for post-singularity civilizations where just about anything is possible and everyone is immortal, nobody will bother with a five-million-year round trip to Andromeda and back. There will be Von Neumann probes to make sure our civilization continues in the event that life in this galaxy is exterminated, and maybe a few posthumans will be like "fuck this galaxy" and leave forever, but for the most part intergalactic travel just won't happen.

Here's what we do. We get ourselves a big-arse rubber band...

Honestly though we'd really need to master Q-axis movement for it to work.

Yeah if this is going to happen, it's not going to use any kind of science we currently know of.

If I knew i'd be on my way already

Best way possible would be to discover a way to be transferred through a wireless line in the sublayers of space itself. Though that in itself is like a miniwormhole.

Cryoships will most likely be the first ships to travel beyond the solar system. We are well on our way to discover what alien worlds are comprised of and if we are able to survive on them. Sooner or later we will try colonization of one.

I would guess assuming if the alien became friend with us (not invade and ensalve/ killed us off) they would already have the technology and share it with us and reverse engineer it to understand it more.

Anywho, beyond currently-thought-impossible faster-than-light travel, cryostasis (and a long ass amount of time), and the ones you crossed out, not a whole lot of options. Until the alien jesus decides to return to us in December. :D

Humans have yet to reach the next planet, but it's theoretically possible.

Reaching other galaxies within a few centuries of travel is only "theoretically theoretically" possible. That is, the scientific theories explaining this might, in theory, be discovered some day.

It's possible, even probable, that humans will colonise other worlds. It might be possible that it might be possible for them to travel faster than light, but we can do little but guess as yet.

There must lie some key in another dimension of the universe. Human science will discover a way to jump or shortcut between solar systems and eventually galaxies (though no doubt intergalactic travel will require immense power). If there is no discoverable way of travelling between solar systems and galaxies without generation ships then surely, that would be a great cruelty built into the very way the universe works.

We could always go to Mars and look around in the ruins there...

Basically, it's moving the universe around your ship or some shit like that. Michio Kaku spends an entire series designing a spaceship to do this, plus weapons and forcefields.
And the science is/seems legit.

We still got to archive interstellar travel (the speed of light seems pretty out-of-reach in the near future), that I think its safe to say the possibility of intergalactic travel is extremely unlikely (if not impossible)

If you got close enough to the speed of light, you could make the trip in what seems a short amount of time even though you actually take millions of years to get there from an external reference point.

The amount of energy to do make that trip would be unimaginably huge though. And you'd have to find some way not to get splattered by the acceleration and deceleration.

Actually colonizing other planets is hideously impractical, and nowhere near the effort. If humans were to spread into space it would most likely be in space stations. There are designs that exist that would be possible to build with present day technology. Any sort colonizing a planet is far further off, and terraforming a planet is pure science fiction and will probably never happen.

Travelling at relativistic speeds would make the journey seem sorter but it would still take a long time. Even going just to Proxima Centauri at 99% the speed of light would take over seven months, not included acceleration time, which would likely make it more on the order of two years to get there. As mentioned the power needed to do this is immense as your ship would get more massive the faster you go, so you would need progressively more energy. That sort of technology is decades, or even centuries beyond were we are now.

This guy knows the deal!
Then we reactivate the Mass Relays and we're sorted!

Well, according to theoretical physics, warp drive (as in, the Star Trek FTL drive) is actually possible, it just needs a /lot/ of energy to work. If we could come up with some way of generating roughly the amount of energy the sun does from an artificial and small enough source, we'd be in business. There's also the option, mentioned above, of an ark ship, but that would take centuries to get anywhere.

Maybe we should just focus on our own solar system first, design a feasible way to get to Mars and back and then we can think about intergalactic

Ok, its very simple. See, we first have to discover free energy. Clean burning, low cost infinite energy. Thats our biggest hurdle at the moment.

After that, space travel becomes far easier. See, because the object in space is completely weightless, so once you get your initial momentum going, space travel becomes far cheaper. So you dont have to fund then entire trip with energy, but reaching the proper speed is the most expensive part.

Then, you plot the course ahead of time, getting 100+ years of information ahead of time. Steering at that speed is impossible, and your biggest risk isnt aging to death, but hitting something, or getting hit by something. So you have to computer do all the controlling. More plotting can be done along the way, with the ample amount of time you'll have. Once you have all the information and space charts ready, your nearly there!

Now the ship itself will have to be rather large. Because of the infinite energy though, creating, producing, and maintaining things will be much simpler. Growing crops will be far easier, because of the ample space you can have ((no pun intended)) and the unlimited amounts of proper lighting and clean water. Food wont truly be a problem, because you can plant the crops in a rotating cycle, meaning every month you'll harvest one of the crops, for sustainable food.
While you cant get all the vitamins and nutrients you need to survive long trips from just plants, the rest you can tightly pack into bullion cubes, to be melted and mixed into water. Fiber and such are easy to keep in space, because of vacuum packing. Literally putting it into an area open to space, keeping it frozen in time.

While traveling lightyears will still take a generation or two, possibly more depending on speed constraints, you can live a happy life in space because of your lack of worries ((kinda)) :D Though, you'll probably go crazy from boredom and have to get tied to the wall with duct tape, it could go alot worse!

And then we combine these two different technology trees with the ingenious methods of the Hitchhiker's guide to the galaxy. Total galactic domination is just around the corner.

Two words, Fold Space.

"Folding" the "fabric" of space-time is a bit of a simplification, but Lorentz Contraction is well documented.

Hang on, isn't that how the Planet Express ship moves through space?

Magic. Only reasonable explanation.

Feh, intragalactic is for chumps. REAL men can hop around star systems.

Ya'know, till the Reapers get horny again.

If General AI comes about, there's a good chance that they'll be able to create their own spaceships, blast out of the atmosphere, and populate the galaxy (assuming tech has advanced a fair amount by then).

Asides from a sort of Star Trek future of several generations living on the same trip (and even then warp drive wouldn't be possible) intergalactic travel seems incredibly unlikely, unless the rules of physics turn out to be wrong in some way. It'd be hard enough for an AI ship.

Some sort of spatial or mass distortion would be the most obvious way to make it practical. As it stands, we're not getting beyond our solar system without the help of an alien race or some ridiculously lucky scientists in the mold of Tobias Shaw and Wallace Fujikawa.

Failing that, we get the likes of Bergholt-Stuttley "Bloody Stupid" Johnson and his distant relative Cave Johnson to sort things out. Just tell 'em we're making a toaster or something.

Well, Unless we find something that is significantly faster than the speed of light, that's sort of a dead end.

I think wormholes are our biggest bet right now. But we pretty much need to harness the power of Zeus himself to even consider something like that.

Folding of space-time involves something roughly like this: am i rite?

On the subject, I would think that bending time and space around the ship would be the most practical solution, if Michio Kaku is a reliable source on the subject.

we have almost reached that point of free energy. soon the ego of people online will reach a point of no return and collapse under its own self righteous smugness. where we plug the power cord in i will leave up to your imagination

I find that Spock is your avatar quite illogical.

The whole warp system present in star trek is at least feasibly possible, and has been proven to abide to the laws of physics, the only problem is that we don't actually know how to bend spacetime, let alone with the energy requirements needed. I think that we'll pretty much be limited to our solar system, give or take a generational ship or two, until we figure that out. I'm thinking bending spacetime to create wormholes will probably be what it eventually will be like. Essentially sets of portals established in space to act as roads to other solar systems, except without needing to be at the destination to finish it. A station would be established around the hole, which would look like a sphere btw, and that'd direct space travel. I think that maybe fusion engines could be a start to getting the power for at least the spaceships, but we're gonna need something orders of magnitude more powerful in order to make wormholes. Unfortunately it's entirely possible, and likely, that we'll all die out long before we figure any of this out. Unless somebody makes huge breakthroughs in the semi-near future (i.e. a few thousand years) I think we'll be stuck here until some other race figures it out for us. This sort of thing is the main reason I really wish I could have a time machine, just to see what really does end up happening in a few hundred, or thousand years to see what interstellar travel ends up like, assuming we don't all die out.

Oh, there was one other thing about that phase of human life. I remember wondering what the internet would be like at that point in time, since light speed would be far to slow to maintain the internet between even the nearest stars, but there's always the quantum entanglement thing, which I remember being impressed that Mass effect acknowledged and used. If we have at least a small server farm on the station or colony that has been entangled with servers back on Earth (or lets face it, the moon), then we could maintain fast internet connections between interstellar distances very easily. Sure it'd probably be expensive, but by the time we would actually be needing a use for that technology, it could probably be done easily enough.

Faster than light speed is some sort of containment field (maybe even tunnels). Im still not convinced that its impossible for an object to travel faster than the speed of light. So well just make objects go faster than the speed of light... if we cant predict the location then well find some way to do so.

Not sure if joking but.... you do know there is no such thing as free energy? Or limitless energy? And if we had that, there wouldn't be any other problems in the world. Matter is "stored" energy. With limitless energy comes... magic. You could make atoms, make food, makes suns, make planets, make universes.....
