FTL travel

well for starters running into a single particle at that speed would atomize you and your ship

>would this even be practical with how much fuel/ power it would need?

Assuming it's possible, it will take AT LEAST as much fuel as getting there at sublight speeds would, and probably considerably more.
>yfw tanstaafl

>atomize

Haha yeah no, it would reduce you to subatomic particles, mostly mesons.

>i wanted to know if there is any feasible way to achieve something like it in real life.
Google Alcubierre Warp Drive. If FTL exists, it has to be something like that. But it still probably doesn't. The whole idea basically requires us to find a way to reshape spacetime the way we want. Which we currently see no way how to. The only thing we know that influences space time is mass.
And even if we could do that, it's still questionable if you can shape space time the way you need for a warp drive. Only then questions come up like "Can you actually put a ship inside the warp field", "Would that ship not die from ridiculous radiation?", "how the fuck do you brake with this thing?" and "does creating this warp field require more energy than the entire universe contains?"

FTL is really unlikely from what we know.
Best we can probably get in the future are ridiculous engines that get us a good chunk of light speed. If we go fast enough we even have relativistic effects that would keep travel time for astronauts down.
With that we could colonize the next few systems.
And before that we can still cruise around the solar system with our shitty chemical rockets and start colonizing that.

>ok, what would be the next best thing for space travel?
Outside of nuclear pulse propulsion, which we aren't going to use, fusion engines are on the distant horizon. Beyond that the slower than light far-future drives are either anti-matter or black hole engines.

>Any sufficiently advanced technology is indistinguishable from magic

en.wikipedia.org/wiki/Alcubierre_drive

you need negative mass, which requires negative energy, and everything inside the warp field would be incinerated by hawking radiation. even then you are limited to 10 times the speed of light, or Cx10. star trek warp 10 is C^10. which won't even get us anywhere really far on the galactic scale with in a human lifetime.

When you travel near light speed time slows down. You can travel very far distances in what appears to be a short time to those inside the spacecraft. To those outside however you will appear to take a meal amount of time to get to your destination.

...

"FTL" travel is impossible since light travels infinitely fast and all objects must follow a continuous path.

anytime ftl comes up on this board you get a barrage of retarded brainlet shit like "NO IMPOSSIBLE" with no qualification when what they really mean is "i think and or feel that it is impossible under known laws". In truth we are all right now "warping" away from everything else in the observable universe, so it stands to reason that we ought to be able to replicate that which leads to the rather more reasonable conclusion "its probably possible with greater understanding but it may not be practically achievable"

that being said most of the FTL you encounter in sci fi is just straight up non sense that is only based in science insofar as they can say "well we unlocked the architecture of nature and it turns out its a lot more complicated / radically divergent than we thought and it enables our technology"

FTL is easy. Just expand space between you and your origin and you'll FTL all the way to your destination.
The whole universe was allegedly invented from FTL inflation and distant bits of it are FTLing away from us now so it's obviously possible.
Just don't try doing it with thrusters.

The most likely method of FTL travel is quantum displacement:

Somehow (yep, this part is the hard part) you have to induce quantum entanglement between where the ship is and where you want it to be, then make sure it's most likely to be where it wasn't before.

>And before that we can still cruise around the solar system with our shitty chemical rockets and start colonizing that.

this. we are going to colonize every planet in our solar system before we leave it.

Wormholes are (((possible)))

Also if relativity is real we could make a meme ship with lots of gravity in the front and lots of "anti-gravity" in the back that could theoretically allow FTL travel, although it would annihilate everything in millions of miles around wherever it travels.

If you teleport a brain with quantum entanglement, will the subjective experience of the original end? Probably. But there's also probably some scientist depressed enough out there to kill himself to make a clone of him somewhere else.

you are not slamming into shit because shit is powering engine to achive 'c'

There is no discontinuity of existence involved in this. That's quantum mechanics!

Warp travel is probs the best bet. Requires far too much energy and tech we will likely never have, but if an asteroid gets in the way of dat event horizon, it's going to go bye bye.

I doubt anybody wants to colonize most of our planets. Mars is terrible enough

? The sun is 8 minutes away but the others would take years even at light speed.

Thats why you also invent deflector shields in your sci-fi fantasy world.

It would be years from the earthling perspective but much shorter for the travelers, they would essentially be time traveling to future when going near light speed. Or that's what people on Veeky Forums tell me anyways

>ok, what would be the next best thing for space travel?
Humans hibernating. They are working on this. Knowing bears and bats can hibernate makes it likely also other mammals can hibernate.

So basically send out a human crew to, say, Titan and 10 year transit time is no issue. Given people are volunteering for a one way ticket to Mars I am sure people will sign up for this too.

From the frame of reference of the travellers not much time would pass, while from for example Earth years, decades or centuries would've passed.

excellent, point it at your enemies!

stars nearest the Sun are still 1.5 to 4 lightyears away.

However from the perspective of the people on the ship the trip wouldn't be very long.

>ok, what would be the next best thing for space travel? are we just stuck with what we have now or is there something better?
Age extension, suspended animation, and/or embryonic colony ships.

Nothing that's going to happen in your lifetime, but we're probably going to have biological immortality before we have interstellar colonizes.

>i understand that it's for storytelling but i wanted to know if there is any feasible way to achieve something like it in real life.
Black hole star ships aren't as sci-fi as the concept sounds. They are possible under current technology, save that we need a good gamma-reflecting material, and a whole lotta infrastructure (a couple of orbital solar panels the size of small states, even under current solar efficiency). Wouldn't get you FTL, but would get you fast enough that you could reach the nearest stars in reasonable time. Stars are sparse out here at the edge of the galaxy, but still not more than 4-8 light years, apart on average.

Beyond that, and the good old Alcubierre drive, keep in mind that we don't really have that great a grasp on physics yet. We don't really know what about 90% of the universe is made of or how what it might be made made of works, exactly. So, other possibilities are bound to raise their heads in the distant future.

the fastest we can go through space is 20%c, as going any faster would probably get the ship destroyed from space dust
unless we can make energy shields, that will probably be the limit for safety reasons

There's not much dust between systems, and you can always send out a plower first, but that'd still be almost too fast - the proposals are usually around 10% (constant 1G accel), which still gets you to the nearest stars in reasonable timeframe, provided we're living longer or have suspended animation by then, both of which will probably be the case, given the time frame involved and the rate the those technologies are progressing vs. space exploration leaps.

Trickiest bit is always slowing down again as you near the next system with all its debris.

>Strong AI
Wrong. We already know strong AI is possible because the human brain exists. We WILL replicate it at some point. Not soon, but we will

Less a list of things that cannot exist, more a list of things /x/ will constantly bring up and invariably go down dream pipes.

>something exists therefore you can create it with technology
lol ok
