DAILY REMINDER THAT HUMANS WILL NEVER LEAVE EARTH

the ultimate sign of a brainlet is someone who believes humans will colonize other planets in the solar system let alone galaxy.

>muh they will just invent a way to travel faster than the speed of light
>muh spacemining will somehow make it profitable to burn a shit ton of (increasingly expensive) fuel every trip

human achievement will turn inwards, look at the progress of our personal entertainment devices over the past 60 years and compare that with the progress of our space programs

also forgot

>but what about when the earth gets destroyed from glogal hotting?

In that event, clearly the best option is to spend a massive amount of resources relocating to another planet that has no atmosphere, ionosphere, or liquid water.

>humans will never faster travel than horses allow
>humans will never fly like birds
>humans will take a tiny brick from their pocket to calculate exactly their location and get worldwide information delivered to them in milliseconds

>DAILY REMINDER THAT HUMANS WILL NEVER LEAVE EARTH

who is manning the space station right now?

It's just a matter of time senpai.

>the fact that people believed things and were wrong in the past justify blind belief that assumes all the physics we know today is bogus

at least humans had observed things flying and going faster than a horse. Has anyone ever proven that a particle can travel faster than the speed of light, let alone a large mass (ie a spaceship) without being destroyed?

again the third example of gps is just an advanced version of the cartography and navigation that took place at the time.

your argument might be stronger if you provided a mechanism for faster than light travel, or even a reason to undertake such a costly mission as colonizing another planet

>science is magic waiting to happen

Go back to your escapist fantasies.

>did you even see interstellar or the martian?

semantics, you know what I mean. 6 people/7 billion might as well be none.

is a generational space ship even possible? aka a spaceship that takes hundreds of years to reach the destination. Is it possible to store enough energy to provide food and clean water for a trip that long?


I believe that while a generational ship might not break the laws of physics, the logistics of it are crazy and humans would never dump that much money into something unless they were under threat of impending doom, in which case it would probably be way too late to start work on such a thing.

The only plausible way for interstellar travel would take time.
Since going fast will probably never Be possible the only other option is either staying here or building a generation/sleeper ship with a solar sail.
This only solves the problem of locomotion and not dying out because of old age. Bigger problems surface when tackling with how to sustain constant energy for a large group of people? Food, water, exercise? If it's a generation ship, how to sustain a constant population without ovet/underbreeding? How to dealer with diseases? How to fix problems with solar sail/ship itself?
I sure some of these problems can be fixed with robotics/A.I but you can't fix conflict-seeking human nature which would undoubtedly cause problems.

All on all, it's an interesting puzzle to mull over on your free time.

in a closed system food and water can be recycled with the help of lots of energy.

Hybernation will never happen. You'd have to build a fully automated ship filled with white embryos and 15-20 years worth of oxygen and food. Have robots birth and teach them according to the proven skills of their white clones on earth. All of this while in orbit, do landing with fully trained white humans over several colony building landing missions.

>HEY EVERYONE LET'S GO TO MARS!!!
>wait, did our candidate lose?
>shit the president is a guy we don't like
>he wants to go to Mars
>LOL ONLY IDIOTS WANT TO GO TO MARS
None of you faggots belong here. Get lost. But nevermind, I'll just get this thread deleted:
(2^3)chan's /pol/ is having a field day with this.

The Solar System can be colonized without violating any laws of physics. So can other systems, there is no need to travel faster than light to do so.

we should go to mars so we can hijack Deimos for a generational ship.

>not 3D printing your food, water and fuel instead

it gives us a species-wide goal to strive towards and opens up the possibility of discovering other species to compete against

this would solve everything

Nice bait fagot

Mars is valid for research, which the Mars mission was already going to provide

The big fat orange muffin comes along and says we should send humans instead which would be idk PRICIER, cuz food,water, oxygen, need to suddenly make a new rocket to accomodate for humans, oh and to make a new rocket, you'd need to do new research into said rocket so the humans wont die halfway down the road due to a malfunction.

This is all entirely moot, because the goal is sending humans out anyway. Just a year ago every single one of you faggots was lamenting NASA's lack of manned missions.

Fuck people who want to go to Mars. Grass is always greener syndrome.
Whats wrong with Earth?
We have water,
We have bars.
Why the fuck
do we need Mars?

Its a nice """dream""" but its not viable, Mars is a dead planet and shouldn't be the endgoal. NASA should focus on other things instead

>hi, fellow Veeky Forumsentists!

We solved Earth.

We beat every other species on earth and made them our bitch. All that's left is trying to improve our own species, but there's no point in doing so if the only threat to the survival of our species is our species. We're turning in on ourselves in an attempt to out-compete one another because there's nothing else. We're ostensibly working towards a global culture and it's killing us.

Colonizing space gives us something to do as a species. Is it meaningful? It is if we make it. It's a huge challenge that we can throw lots of people at. Gives us something to do.

>we beat every other species on earth and made them our bitch
>literally dumb as shit living organisms who will lick your hand if you give them food
>mfw

>is a generational space ship even possible? aka a spaceship that takes hundreds of years to reach the destination. Is it possible to store enough energy to provide food and clean water for a trip that long?

Stupidest possible way to travel to the stars.

We'll almost certainly use nanostarship Von Neumann machines to reach another star (probably Proxima Centauri), then send them all the data they need to build a colony after they arrive and construct a receiving station...including the DNA required for humans, animals, plants, etc. Then they'll construct more VN machines and repeat the process.

That's presuming people are still physical and biological, and not virtual, in which case, fuck the colony...just convert the whole P. Centauri planetary system into a matrioshka brain.

>blind belief that assumes all the physics we know today is bogus
All the physics we know today says colonizing the solar system shouldn't be all that hard, and visiting other stars is mostly a matter of preparation and patience.

I know when you brainlets first learn that Star Trek isn't real, it's a crushing blow, but FTL travel is completely unnecessary, and we should probably be relieved if it turns out to be impossible.

If sci-fi-like FTL travel were possible, our planet would likely have been taken over by aliens before we evolved. Our galaxy's under 200 thousand light years in diameter, and the nearest galaxy is only about 2.5 million light years away.

If it only took days to travel light years, and it was affordable, then the first civilization to develop a little beyond our current level would take up a whole galaxy as quickly as they could run their exponential reproduction, then hopping to the next one would be like the task of moving to the next star system as it faces us today, except they'd have much greater resources to afford to build world-size ships for comfortable migration. So in a cosmic eyeblink, they'd spread to many galaxies. In a few million years, they'd have taken over a sphere thousands of galaxies in diameter.

Interstellar, even intergalactic, expansion is possible in our universe, but it'll have to happen slowly. It would take billions of years to spread thousands of galaxy-spanning hops away, and the universe is only billions of years old, stars only last billions of years, life evolves from cell to civilization in billions of years.

So this prevents huge areas from being promptly dominated by the first intelligent life that appears in it.

>thinking that humans will choose to dump their money and resources into slow galactic travel

you wrote a lot of text about how something that doesnt exist is bad

>If it only took days to travel light years
wtf am I reading!?

>a spaceship that takes hundreds of years to reach the destination. Is it possible to store enough energy to provide food and clean water for a trip that long?
That's not hard even with present-day technology. Fission fuel is plentiful and has extremely high specific energy. Fusion fuel is even more abundant, once we have that technology (in fact, we can use it now, if we accept a high enough rate of energy release, i.e. H-bombs).

>I believe that while a generational ship might not break the laws of physics, the logistics of it are crazy and humans would never dump that much money into something unless they were under threat of impending doom
Stop thinking of "humans" as one group. It's never been like that, and it never will.

Some of us will launch a generation ship to get away from all the other crazy assholes.

Actually though, it doesn't even need to be a generation ship. Let's say we get modest life extension, two hundred years of youthful vigor before the brain goes (all we need for that is the ability to put the brain into fresh bodies). The nearest star is under 5 light years away. Travelling at 0.1c, a 50-year voyage might seem a comparable investment in time to getting a doctorate.

Even nuclear pulse propulsion would be sufficient to reach 0.1c. With more advanced propulsion options, longer hops are likely to seem reasonable.

>FTL travel is completely unnecessary
So are cars, but we still use them.
>our planet would likely have been taken over by aliens
>would take up a whole galaxy
You assume it hasn't already been taken over. Who knows, maybe the act of killing off everything on an already inhabited planet could be seen as a threatening gesture (or otherwise looks bad in a political sense) to most species. So is unlikely to happen due to the species taking over the planet not wanting to gain (more) enemies (other equally advanced species that were eavesdropping on the slaughter).

>generational ship will be a focused effort by a restricted population

kek we have all of the western world collaborating on the ISS right now and that might as well be a mosquito compared to the boeing 747 that would be a generational ship

>its okay to spend a lifetime on a ship because humans will live for hundreds of years and get brain transplanta

this technology is exotic even for sci fi films lmao if we are believing in future tech why not believe in ftl travel?

>fission fuel is plentiful
so are the energy needs of a ship that has to meet the energy needs for generations of humans over hundreds of years

>3D printing fuel

Brainlet detected

>we have all of the western world collaborating on the ISS right now
The ISS is a pork project, paid for mostly by the US government, as a way to give money to political allies. It's not doing any particular job, and the people in charge of it are doing the opposite of trying to keep costs down.

That's a fantasy land here in the real world. What NASA spends doing things has no relation to what they would cost if undertaken by a private, cost-sensitive organization.

>exotic even for sci fi films
What has that got to do with anything? Life extension to 200 years is a reasonable near-term extrapolation of medical technology progress. The brain is believed to age mainly from the breakdown of the body supporting it. Provided with healthy young blood, it should last at least 200 years. There are various ways of producing young organs and connecting them to brains.

Sci-fi's driven by what makes a good story, not by what's likely to actually be done.

>>fission fuel is plentiful
>so are the energy needs of a ship that has to meet the energy needs for generations of humans over hundreds of years
Try doing the math instead of assuming and trying to argue by waving your hands. This isn't a serious obstacle. Almost none of the cost of nuclear power from a breeder reactor is uranium.

Look at what happened in the last two hundred years. Look at what happened in the last two. We're clearly still in the middle of a period of rapid technological advancement, not coming to the end of one. You have to be some kind of monkey to think stuff being hard right now is an argument for it staying hard forever.

> you need FTL to make it to mars
stay cucked kido

> Making new humans = Traveling
Colonizing? Sure, but that's not traveling. Traveling implies you yourself get to go there.

>You assume it hasn't already been taken over.
Aliens that are just hiding themselves are an even sillier idea than a god that's just hiding himself. Might as well assume little elves build each room just before you walk into it.

>Who knows, maybe the act of killing off everything on an already inhabited planet could be seen as a threatening gesture (or otherwise looks bad in a political sense) to most species. So is unlikely to happen due to the species taking over the planet not wanting to gain (more) enemies (other equally advanced species that were eavesdropping on the slaughter).
You get that the "The Culture" series runs on pure author fiat, right?

>lets spend exorbant amount of money colonizing a place that could never be anywhere as hospitible as the worst earth desert

>hospitible as the worst earth desert
You mean like southern California?

Antarctica.

>Colonizing space
Uropean Limy faggot

>fuel is expensive

Fuck off, fuel is dirt cheap, hardware is expensive. A rocket might carry several hundred thousand dollars worth of fuel, if it's a big rocket using a more expensive fuel like hypergolics. By contrast rockets cost millions to build. A rocket's fuel cost is essentially nothing by comparison.

By throwing away our hardware after every launch (because designing and building reusable rockets is hard) we've become accustomed to the insane launch costs.

Now that we're actually seeing real progress into reusable booster territory we can expect to see large decreases in costs in the future.

>unless they were under threat of impending doom
>implying all humans aren't constantly under the threat of total annihilation at any time, currently
shiggy

>Mars is a dead planet
MEME

All planets are dead, dumbass.

Also, if you're living in a sealed environment, it doesn't matter what it's like outside. Take it from a fucking leaf.

I meant that even using reusable rockets, the fuel needed to take mined resources back to earth would make the entire enterprise unprofitable. People commonly advocate space minimg as some way to incentivize space tech development

no ionosphere will fuck your shit up pretty fast

enjoy that cosmic radiation

Dumb. Dumb reasoning. Yellowstone supervolcano could blow tomorrow and take out most of human civilization and there's nothing we can do about it except spread out into the solar system where there aren't any active supervolcanoes.

Saying humanity as a whole has completed Earth and wants to move on now like some sort of new game plus scenario is retarded. It's easy to think that stuff when you're in a safe country with a more or less constant supply of electricity and water to use and food to buy, but for the vast majority of people that isn't true.

The fact is Elon Musk and the like want to go to space because they may think it's important, but more importantly they think they can make money doing it. If they can, and end up colonizing Mars/Moon/not Venus, then good on them.

>what is aluciber drive

>generations of humans over hundreds of years

A big tank of thorium salts dissolved in water.
Enough thorium to fuel a LFTR for 500 years.

That is of course only necessary if the propulsion technology either doesn't run constantly or doesn't generate enough waste heat to be useful for generating electricity, which is doubtful.

Habitats built for human habitation on Mars would be as habitable as the most balmy, benign habitats on Earth, except you can control the weather and don't have to deal with mosquitoes giving you zika.

Colonizing Mars is necessary to colonizing the entire solar system. It has a shallow enough gravity well to make getting to space much easier, but also has enough resources like water and CO2 ice that it's easy to meet the supply demands of a colony with a lot of industrial activity. Colonizing Mars would let us build all those fancy ass orbital habitats and massive interplanetary ships and so forth that science fiction writers cream themselves over.

The world is bigger than just the Earth, basically, and it's about time we started spreading out a little. Not that it's realistic to think that a large or even that significant of a fraction of Earth's population would ever go to space even in the most optimistic scenarios.

>cosmic radiation
>what is 2-3 meters of water or several meters of dirt as radiation shielding

are you actually too ignorant to live or just pretending

I never said mining space would be cheap enough that you'd be able to sell what you've mined back on Earth and make any profit. I don't think that business model for space mining is even close to economical.

Space mining will only be done to produce goods in space, which will be used in space. That's fine.

To make money in space you just need a launch vehicle with a cheap enough ticket price and a destination people either want to go to, or they want to send their shit to.

The ultimate definition of a brainlet is someone who believes humanity is not destined to conquer the galaxy and eventually the entire universe.

Low earth orbit isn't that big of a deal compared with interplanetary travel
