Better question: How much longer until we die out?

A lot will depend on whether we manage to create a superior artificial intelligence and safely use it for our own good. However, the creation of such a powerful tool will be the most riskiest thing the mankind has ever done, especially if we are still divided to multiple countries and alliances.

I'm trying to remain optimistic about the future though! Much more fun that way.

space travel isn't possible at all, we can't actually escape the ionsphere without being blown to bits. the fact that people actually believe this is mind-blowing - look at the facts.

This "rock" is our home planet, dipshit. We should try to save it instead of leaving it.

I don't think the Earth needs saving. It will be here for a couple billion more years.

>>7457091
We will most likely die before it is feasible. I do not see the future of humanity as hopeful as others. I see a force that has worked against us every step of the way.
This next decade or two will really determine if we can finally overcome that force forever.

Humans as they are will never disperse; we are intrinisically linked to the biota of Earth. We can no further sustain ourselves outside of Earth than a cell can survive outside of an organism. We can take a petri-dish to sustain us, but that replication of biota is incredibly expensive and wasteful. Much better to engineer something new such as AI or mind uploads, to be resistant to:

>radiation
>hard-vacuum
>temperature extremes
>high acceleration
>inertia

All of these are deadly to humans, yet the norm for space travel.

>>7457091
People, we are in a race against time. Human population is growing at an alarming rate. How many years will our resources last us? 200? 300?

Humankind is fuck out of luck if this is one of those great "filters" mentioned in the fermi paradox.

And all we do is develop the newest entertainment and health systems while our time is running out. Just how lucky will humans be, to be able to discover time/space travel in the next 50 years, when resources undergo the depletion process?

The human population has doubled in the past 40 years. There's going to be a big crash within a couple of decades.

>>7458052
Species need pressure to adapt to hostile enviroments, such as climate change, predators, etc
We are maybe approaching to a time where something catastrophic may happen, and that will be the moment when we either die because of it or survive it.

>>7458052
I heard the same lamentation 20 years ago.

In the end it doesn't matter. I'm pretty sure everything that was lost with humans will be discovered again with another species.

I'd say after us the cockroaches should have a run. They seem to be able to adapt to hostile environments better than us.
Or the waterbears they could probably launch themselves into space without suits.

>>7458104
We're not going to die out due to overpopulation or climate change. However they most likely will fuck society as we currently know it, maybe beyond repair.

Humans don't respond well to threats that arn't immediate. There's the whole prisoners dilema, as in no one wants to cut back because no one else is.

Our genes program us to have offspring.

The reason we won't go extinct is due to our vast population, and intelligence. Some people will always survive, it's just basic statistics.

It has been clear for at least 40 years that human civilization is driving at full-force towards a cliff. The average person is uneasy but hopeful about the future, but the reality is there's going to be some serious disruption.

I'm of the opinion that human society is an evolved phenotype, and that the meta-organism's evolutionary strategy which enabled humans to become so successful is hardwired in all of us.

No matter what we say or do, we just contribute to part of the feedback system of the meta-organism, which has possibly been coopted by the parasitic sociopath mutation. Bread and circuses followed by collapse has been repeated for millennia.

Our shitty meat bodies weren't designed for space travel. Of course humans won't admit it so soon, but eventually if they're able to populate the Solar system, and even start planning travelling to other stars, they'll realize that becoming part of the machines is a lot more efficient.

>>7458698
>and even start planning travelling to other stars

traveling to the nearest star from earth would take you roughly 4 years (travelling WITH speed of light). Considering the fastest rockets are way slower than that, I'd say getting to the next star would take a minimum of ... idk .. maybe 40000 years? Have fun with that, anon.

>>7458703
If you're willing to think ahead, you need to also assume that everything more or less improves, and that includes propulsion engines.

>>7458705
So you think that one day humanity will be able to travel with 99% of light. Ok maybe, I don't mind. But remember the distances in space. Even going with 99% speed of light (which I think seems very unlikely) is 'very slow' considering the huge distances.

>>7458653

Quality response friend. Well memed.

>>7458705

Also a species that can abandon "meat" would be immortal and could hibernate at will.

>>7458703
>muh time
Brain computerisation.
Literally not one fuck given about the time required to travel, better propulsion system or not, when you're an immortal in a blissful virtual reality with your cartoon horse.

>>7458724
with 99% the speed of light you can travel to something 100 light years away while only aging 28 years, so no, 99 the speed of light is not slow

>>7458724
I'm not being that ambitious, it will be done in small steps. First they'll get to 1%, maybe later to 3 and 4. Something like 10% would be reasonably bearable. However I don't think humans will be able to coexist in unison when they spread out to multiple star systems. They'll be able to exchange information but it will be outdated. If we can't become one with machine, they'll still have to work on some sort of cryosleep. Some imagine huge ships where people live, age and reproduce on the ship while they travel to another star but I personally think it's a huge waste of resources.

Imagine though if you're on a ship that travels at 10% and by the time you get there you're not the first one to arrive because they developed even better engines. I always found that horribly depressing to think of.

>>7458734
Sadly I think most people are too sentimental. Maybe the age of VR will change our culture though and simulated lives will be acceptable at some point.

>>7458738
I think you are wrong there. Traveling a distance of 100 light years with 99% the speed of light will make you age nearly 100 years. The effect you are talking about refers to reference systems travelling relativly to each other. Then the clock of System A goes different from the clock of System B, but you will age 100 years, if you travel 100 lightyears with 99% the speed of light.

>>7458741
>imagine huge ships where people live, age and reproduce on the ship while they travel to another star

This seems very difficult to me, I mean socially.
I ask myself it is really necessary to survive (as a species) at all costs, u know?

>>7457474
brah we're all gonna make it

>>7458744
It is the acceleration which does the magic. A satellite moving in an ellipse around the earth being equipped with a clock. The clock on the satellite slows down compared to clocks on the earth due to the acceleration required to keep in orbit. According to wikipedia the effect can in practice be time moving some tens of microseconds slower per day.

>>7458756
OK very interesting. Got link to article pls??

>>7458758
It's called relativity.

>>7458756
>>7458760
Ok, sorry my english is not perfect. I read the sentence again and I now get what you mean.
But I still think that does not mean you can travel 100 Lightyears with 99% the speed of light and only age 28 years. People staying on earth would see you age slower, thats right, and when you come back you would be younger than the people on earth. But traveling 100ly of distance would still make you age 100 years (considering you are going 99% the speed of light). As I said; the effect is relativ. See ---> https://en.wikipedia.org/wiki/Time_dilation

>>7457099
Actually I think this is the only reasonable outcome. Given that humanity is spared long enough from apocalyptical events, it will eventually get to the technological singularity. At first there might be some regulations to keep the AI submissive to the humans. But everything that can happen, eventually will happen and these regulations will be bypassed by some human or maybe even the AI itself. This will be the end of humanity.

>>7458777
The funny thing is, when you travel 100Ly in the frame of the earth, you do not travel 100Ly in your own frame do to Lorentz contraction ( actually in your own frame you don't travel at all but the destination gets to you, but still the distance is contracted) . Therefore theoretically you could do it within 28 years. Practically however, accelerating to the speed of light would already cost you about 30 years because the human body can only bear about 1 g on the long term.

>>7458785
which is why fluid suspended stasis would be necessary for harder acceleration

>>7458809
I think you still cannot get much higher than a few g, can you?

>>7458816
I doubt it, probably 10G absolute maximum and more likely a 4-6G prolonged accel

>>7458052
>Human population is growing at an alarming rate.
>>7458084
>human population has doubled in the past 40 years

Population growth, by percentage, has been in decline since the early 60's, and growth by raw numbers has been in decline since the 90's.

If this trend continues _indefinitely_, we'll be wiped out due to lack of reproduction.

>>7458882

>>7458882
Couldn't they just produce some organic bodies on the go and make it more relatable for us to interact with them?

Guys, this can happen. We use our power and influence to ensure the Green Fascist Front can take control of the UN, destroy capitalism worldwide, provide free birth control to all women, and reduce human habitat to clustered cities and a few sparse rural villages while the wild is allowed to reclaim 90% of what it lost over the last few thousand years. Then, we can extend our lives without overpopulating the planet, and with a healthy world wide ecology, develop a space-age civilization at our leisure. Sound good!? make it so.

>>7458879
Population is growing all the time though. They estimate that population will grow by2.6billion in next 45 years. Also even if population would decline to critically low it would be pretty easy to just tell everyone to start fucking and put some system in place where everyone has to/gets to fuck random people so women would get pregnant(silly idea but just an example). over population is much harder issue since you would have to deny people of fucking without pills or condoms and maybe start killing some people off.

Perhaps, but the reality is that space travel is a much more feasible concept once you take the fragile human body and their biota requirements away. I posit that if you said to the average person that they could be immortal, feel no physical pain and could travel anywhere in the universe, they'd dump that meatbag like it was nothing.

It would take a very large number of years --more years than mammals have been around--to try to artificially colonize the whole planet with plants, water, and an atmosphere. We would need centuries of building to get something the size of NYC going. (Think of how much NYC would cost in today's dollars, but make it 50X more expensive because it's "space-stuff")

We could build a bunch of rockets, but with our current technology, the project would almost bankrupt the U.S. as much as the Iraq war. We'd basically need a small society of people living in space to really plant the seed, and that would take a lot of rockets and sci-power.

If we were to build, let's say, 100 years worth of "Bio Dome" on the surface of another planet the size of San Fransisco. If something like the San Fransisco fire happened there, there goes the entire project.

I think war and our artificial system might and could wipe us out before then.

Fun fact: Supposing that all humans are born in a random order, chances are that any one human is born roughly in the middle. This would suggest that not too many times as many humans will be born as have been born. On the other hand, the lower number of future births might have a happy story associated with it rather than an unhappy one.

Are you retarded? Inertia (which is the reason high acceleration is an issue btw so you kinda said the same thing twice) is directly related to and only a problem in gravity. This may be news to you but the amount of gravity experienced by a human out of atmosphere is negligible.
