So how do we get there? If you say warp drive or EM drive, please remove yourself from the gene pool

You know, we just need a ship that's capable of near lightspeed travel, and also large enough to carry enough living space to sustain a colony for 1200 years

Yeah, space travel is fucking impossible

Let's not go then.

That's because space doesn't exist and the Earth is flat. That's why they came up with the convenient lie that all these planets and stars are so far away, so that we'd have an excuse to never visit them.

Stars are just luminaries. The model of the universe, as we know it, is a lie.

>build a ship that works independently for several thousand years

With nuclear pulse propulsion we can only reach 30% the speed of C.

So, we'd need several generations to reach it.

Several is an understatement.
at .3c, not factoring in acceleration and deceleration that's 4000 fucking years.

I'm assuming by the time we decide to go people can live to like 115 pretty easily.

So like 2050.

Hopefully we have something beyond nuclear pulse propulsion then. But we probably won't.

Only from earths point of view. Much shorter for the people on the ship

>30% the speed of light
We can't go that fast with current technology

What the fucks nuclear pulse propulsion

0.3c isn't really going to bring on much relativistic time dilation

Blowing up nuclear bombs behind a ship.

It's so powerful and produces so much force it doesn't matter what your mass is, you're accelerating.

That would give a good purpose to a lot of our nukes, actually.

How do you slow down?

Turn around and fire, same way you slow down a regular rocket

Same way you speed up. Timed bombs the opposite direction. Only issue is how to propel them in front of the ship at that speed.

You can't really do that at 30% the speed of C.

Why not?

>This planet could support life

Who gives a shit. We're on the brink of AIs and even human uploading, and thanks to pop-sci, space opera bullshit, people still think shit like "water" and "air" are necessities for the spread of our intelligence and civilization.

The future will be a lot weirder than anything you're seeing on a movie screen...

en.wikipedia.org/wiki/Matrioshka_brain

It only takes constant 1 g for 1 year to reach relativistic speeds which would allow a tour of the visible universe in a single lifetime for the traveler.

Please describe your vehicle with enough fuel and powerful enough engines to constantly accelerate at 1g for a year

>1200 light years
>life time

What you guys need to take into consideration is the principal of relativity--you know that little thing Einstein wrote about in his book, e=mc to the power of 2. All you need to do is throw a jump rope like device on a rocket ship that spins around the ship at the speed of light--this will be easier to do because you don't have to worry about maintaining life, though the technology is still a bit out of reach--and because the "rope" is spinning around at the speed of light, but the ship is still traveling with it, you are effectively traveling at the speed of light, but not.

>All you need to do is throw a jump rope like device on a rocket ship that spins around the ship at the speed of light

Nigger do you even time dilation?

do other planets hate him?

Lets go.

Build something that travels speed of light (kek).

Generational ship, Basically a flying city that will be fully crewed for 2000+ years until it gets there and they set up a colony.

The funny thing is only the first generation will have volunteered, it's pretty much destined to fail, but aside from breaking the laws of physics there is no other way.

>What is time dilation
It's like you're still living in the preeinsteinien dark ages.

But each consecutive g needs more energy than the previous one.

>We're on the brink of AIs
We HAVE AI's if you're loose enough with the definition.

Just no.
We're so far from this, we can't even tell if it's possible.
It's like asking a cave-man about QM.
Solve the hard problem of consciousness, then let's talk about it.

>time dilation exists

With suspended animation today's billionaires might make it. Never know.

So they found another roughly earth sized planet and immediatly insinuate that it "could" support life even though we know nothing else about it like does it have water? A breathable atmosphere? Tolerable temperature? Just the right amount of surface gravity?

>It only takes constant 1 g for 1 year to reach relativistic speeds which would allow a tour of the visible universe in a single lifetime for the traveler.
Not even close.
One g for one year (ship time) gets a top speed of 0.775c, and tau would be 0.632.
OP's journey of 1200 ly would take 1550 years to an outside observer, and 980 years to those on board.

>Or just send the ark with genetic material and robots
Frozen ova and sperm are good for decades, not centuries,
And we don't have artificial wombs.

>Hopefully we have something beyond nuclear pulse propulsion then.
en.wikipedia.org/wiki/Black_hole_starship
Best case scenario, we can accelerate at one g (maybe better) for about 3.5 years.
You'd reach a top speed of 0.9985 c, tau would be 0.05475.
It would take about 68 years (ship time) to get there, but then you'd have no way to slow down.

The black hole from the drive only lasts 3.5 years, so you can't save half for deceleration.

>at .3c, not factoring in acceleration and deceleration that's 4000 fucking years.

>Only from earths point of view. Much shorter for the people on the ship

>0.3c isn't really going to bring on much relativistic time dilation

Tau would be 0.954, so instead of 4000 years, those on board would "only" experience 3816 years, plus a little to account for acceleration and deceleration.

>With suspended animation today's billionaires might make it. Never know.
Well, not "today's billionaires" since there's no such thing as suspended animation.
You might as well wish for warp drive.

it's about time someone invented a wormhole machine

i want that capacity to exist within my life time
like 40 years

then i want all of us to go over there and start anew, with everyone given everything and the only rule of law being you have to love everyone

bro

First of all 1200 light-years is not happening, second of all I'm pretty sure there's decently habitable planets around Tau Ceti which is like 11 light years away. We could get there in 30 years with nuclear rockets. Second of all this is jumping the gun for Mars is the most achievable target of all.

>pretty sure there's decently habitable planets around Tau Ceti which is like 11 light years away
Tau Ceti e has a gravity of about 2g.
So even if there's life there, it's not a new home for humanity.

We need two blackholes then. Easy space travel, man, eaaasy.

I dont see problem with two g. Cant we just somehow genetically modify humans to reabuild them so they can live with constant 2g?

I think in the future all space guys will be modified accordigly with their mission so we dont need to worry about bad envaironments like ones with two g.

Wouldn't that just mean that people have way more problems with bones for x generations and get huge calves and quads from lifting twice their body weight?

We could probably find a workaround with near future medicine around the problem with bones. Maybe just some implants to support the spine etc.

>Cant we just somehow genetically modify humans to reabuild them so they can live with constant 2g?
Presently? No. We just don't have the technology.
Someday? Probably not.without dramatically shortening the human lifespan.
There are some serious engineering issues here.

>all space guys will be modified accordigly with their mission so we dont need to worry about bad envaironments
"Missions" can/will be carried out by machines.
Permanent habitation only serves the human race in the sense we'd stop keeping all our eggs in one basket, and space habitats can do that.
It seems much more plausible to alter our environment than ourselves.

we can drive teslas

>Wouldn't that just mean that people have way more problems with bones for x generations
If "x"=infinity, then yes.
You know how people say "if an ant was as big as a human, they could lift a car"?
That's bullshit.
An ant scaled up to human size would collapse under it's own weight.
You need a design that works with the scale and gravity.

>and get huge calves and quads from lifting twice their body weight?
You'd spend most of your life in an acceleration couch, so no huge quads.

And most importantly, the human heart wasn't built for that kind of load.
You'd need to be really short with a low BMI, and a heart that's a much bigger percentage of your body mass.
So forget big muscles (except the heart and diaphragm).

there is no other practical way of traveling through the universe than a warp drive(or other similar methods) so yeah we aren't going anywhere until someone figures out how to build it.

I don't understand why people are so perplexed by the idea of space travel, if we build a big enough elastic band we can probably slingshot spacecraft this distance

Generation ships, but that will never happen.

Near light-speed doesn't mean light-speed. That means the 1,200 light-years distance takes far far longer to cross. The best humanity will ever achieve will be about 10% the speed of light for any space faring vessel carrying humans. Keep in mind the fastest man made object is Helios 2, which traveled 157,078 miles per hour (0.0234% the speed of C which would only reach 0.2808 light years distance in 1,200 years).

Light speed is about 669,600,000 miles per hour.
10% of that speed is 66,960,000 miles per hour.

If the 10%C space ship could instantly start and stop traveling 66,960,000mph then the 1,200 light year trip would take 12,000 years to travel (math is probably wrong here somewhere but you get the idea). However, perfect acceleration and deceleration isn't going to happen. Instead you accelerate half the distance and decelerate the other half, resulting in variable speeds and longer flight times.

>Yeah, space travel is fucking impossible

You god damn right it is, in any human context. Humanity won't even be the same species by the time anything we launched 1000 years ago, using modern technology, reached Kepler-62f.

But you need infinite fuel to do that.

That's shit.

>there is no other practical way of traveling through the universe
Generation ships with anti-matter reaction drives?
Let's say you build a self-sufficient space habitat large enough for a stable breeding population.
Accelerate to 0.01 c, and get *somewhere* eventually.
Repeat until find new home for humanity.

>That's shit.
Well, Veeky Forums is officially dead.
Brainlets are seriously discussing astrophysics and dismissing a well studied phenomenon as superstition.

>time dilation belongs on holy shit this is either an amazing troll or Veeky Forums is truly trash now

>That's shit.

So, 10% C will take 23,910 years to travel 1200 light years.. Plus the additional acceleration-deceleration times. Even that seems wrong. Regardless, it will never happen.

There are people out there who dismiss Einstein purely because he was Jewish.

yes, and we tell those people to go where they belong, which is

phys.org/news/2010-04-discovery-quasars-dont-dilation-mystifies.html

More like theory of relativity is completely incorrect. Time itself doesn't even exist.

Fixed.
Now you'll just have to fill the empty ones with actual /x/ shit.

Found the /x/tard.

>listening to /pol/, ever

/pol/ is always right.

Ironically, you're the most /x/ of posters in this thread. Assuming you're behind some or all of the brainlet posts.

Veeky Forums has already dipped below 100 IQ, let's not sink it down to 50 by introducing /pol/ cancer.

>thread about traveling to other planets 1200 light years distant

This is an /x/ thread, wonderlord.

Yeah it is, however;
Time dilation is not. Nor is any of the other emptied slots in that meme bingo.

This. UFOs, the concept of aliens traveling 1200 light-years to us is /x/ but this thread, the concept of humans traveling 1200 light-years to them is not /x/?

But it is possible technology, add some inmplants, which we will probably get at some point in the future. I still think it is more possible task to modify say 200 humans, then invent some shit like antigravitation (which is probably not possible at all) or true FTl or terraforming. And terraforming wont even be able to alter gravirational force of a planet, so we still cant alter environment to become fully capable to support human lifes.

this
i just want to feel humanity and hug some friendly people

>Anti-gravity
>FTL
>Terraforming

I have a bad wording, sorry. I meant that this shit is probably impossible at all.
Its much easier to somehow modify humans, couse we cant invent magical shit.

>and also large enough to carry enough living space to sustain a colony for 1200

From the point of view of the colonists, the journey would be shorter than 1200 light years because of relativity. It gets shorter the closer you get to light speed.

>That's Wow, this guy just disproved relativity.

You should publish your paper and become famed throughout the world as the guy who btfo Albert Einstein.

>fly 1200 years
>meanwhile earth discovers faster method
>arrive to see it's already colonized by humans

FUCK

I wouldn't even be mad

>only

What is /x/ about UFOs is not that aliens travelled to our system, but rather it is saying that they are flying around in saucers acting like retards and we haven't actually detected any of it.

Aliens aren't necessarily /x/, but the popular misconceptions about aliens and space are /x/.

>The phenomenon of time dilation is a strange yet experimentally confirmed effect of relativity theory.

It's like you didn't even read the article.

That's a top speed of 0.1c, and an average speed of half that (0.05 c).
Since time dilatation is negligible, it should take about 20 times as long as light does to cover the same distance.
1200 ly * 20 = 24,000

But look at your acceleration figures.
You just input a ridiculously low acceleration figure (8 micro-g's??) so you'd get 0.1c for your top speed.

Plus, this tool assumes constant, uniform acceleration/deceleration, which isn't plausible for 1200 ly.
But it should give you an idea about what's possible.
Try Epsilon Eridani, 10.5 light years out.
Say we could pull 0.5 g for a few years, maybe with a black hole drive, bussard ramjet, whatever.
It would take almost 14 years to an outside observer, but less than 8 for those on board.
One g cuts travel time down to 5 years.

That sounds far more plausible than reaching Kepler 62f.

Every UFO debate on Veeky Forums gets shot down with the one argument that FTL is impossible. Therefore this thread should be shot down as well on that basis.

(cont)

And if we ignore the engineering, and just assume we could somehow accelerate at 0.5g for decades, the 1200 ly trip would take 25 years for those on board.
One g lowers travel time to just under 14 years.

We'd need some serious engineering/hardware to do that, but physics itself doesn't stop us from reaching Kepler 62f in a single lifetime.

This thread doesn't assume FTL is possible.

The problem with saying that aliens have in fact arrived in our system is that we would be able to easily detect their presence because the everyday running of their space craft would give off so many emissions.

>▶
>just assume we could somehow accelerate at 0.5g for decades

The ability to change momentum (i.e. Force) decreases proportionately to 1/(gamma) so constant acceleration for decades is a crack dream.

They arrived once in the 50s, maybe returned in the 90s. They don't fly around every day.

That font is absolute garbage

space craft are quite literally bright lights against a dim background. We would detect any space ships in our solar system.

Because FTL is not possible, you can't just come and go as you please.

Obviously. Why do you think we call NASA "Never A Straight Answer?"
