Before you go too far down that line of thinking, I want you to pause and ponder two questions: "Would I say the same about other species on earth?" and "Is humanity unique among other species?"

If the answer to either of these questions is "No", and you still think that life on earth is precious, then there's a contradiction here. And if you don't think life on earth is precious, well, then why do anything? May as well just commit suicide.

Do we know Mars is uninhabited? And what happens when we leave space trash on the first planet which IS inhabited that we don't realize it's inhabited and infect the locals with something? Even if it's small basic life. And we gently caress it up. I'm just not sure what we're bringing to the table where we shouldn't be using extreme caution and this isn't a species known for extreme caution.

But how do you know that? There's no guarantee that something else will evolve in a few million years that will be able to develop a space program. What if humanity is the only species on earth that ever manages to do it? Say humans vanished from the world tomorrow, and nothing - not some descendant of elephants or whales or chimps - nothing ever does it again. Life continues as it always has for the past 500 million years or so, reproducing and evolving, and then as the sun gets hotter, plants will be unable to cope and the whole planetary ecosystem collapses. Then, after another billion years or so, the sun will swallow the earth and even bacteria will be gone.

What will the point of any of it be? How can this be a good thing that you look forward to? All of the suffering, all of the evolution, all of the work that people have done to try to protect one species or another, all of it -- none of it will have mattered.

Even if we manage to 'save' things, there is an universal (literally) limit of how long this can keep going on. Eventually, the universe is gonna reach death of one kind of another - entropy is merciless. Does that change whether things matter? Does the timeframe we manage to continue make it matter more or less?

These are rhetorical questions, of course. In philosophy, the examination of these led to existentialism. Your mistake is assuming a) things have a point, and b) that things not having a point is bad (as evidenced by your 'might as well commit suicide if nothing matters'). In a nutshell, just because someone's a nihilist and believes nothing matters doesn't mean that person then abandons their life. Instead, it leaves them free to find their own meaning. It's actually very liberating to reach this conclusion, and be able to pursue your own interests, experiences and ideals as your raison d'etre.

Perhaps your meaning is to continue this as long as we can. That's fine. 1glitch0's meaning seems to be that humanity isn't good for other lifeforms around, and while he (probably) enjoys his life and tries to do good he thinks it might be better for the collective us to peter out to obscurity - even if intelligence in this corner of the universe goes with us. That's also fine, from an existentialistic, nihilistic standpoint. But you're arguing past each other, because your idea of value is different.

What about this.

The universe has no life other than our own and whats on earth.

By developing space travel, we can preserve *all* like on Earth, across the cosmos, like Noah's Ark.

If the Great Filter is behind us, then its likely far enough behind us that maybe trees and bushes and ants, and fish simply just don't exist anywhere else.

Ergo, space exploration is a net good, because of how much more life of all kinds that will continue to exist.

The ethics of like, if its okay to release cats and dogs and burmese pythons in some other planets ecosystem can wait until we actually discover the existence of such.

Like I assume some of these posters believe genocide is bad, why do they support genocide of everyone? I don't think people in the third world appreciate having their cultures being eliminated forever because of the poor decisions of white people?

In my belief, we should focus on surviving and repairing from the climate crisis in order to explore and colonize space. Absolutely we should be making some investments into robot probes and SETI and stuff - basic science is very important, but the overarching focus of society should be to making sure that we and as many life forms as possible survive the abrupt climate change. My basic belief is that all the good things that leftists advocate for - UBI, socialism, anti-racism, anti-discrimination, environmental protection, fully automated luxury communism, etc. - are prerequisites to a society that can peacefully explore the universe. Therefore, if we want to ensure that we're not annihilated by a random space catastrophe, or simply obliterated by the natural evolution of the sun, it's incumbent upon us to work towards all those goals.

Which is why there should be a UN space organization funded collectively by the UN member states with most of the burden by the Permanent Security Council members and the extended temporary members.

I'm not arguing that privately funded space exploration is good, especially when it mostly free rides off of publicly funded research that made it possible for a profit. The state should be massively be funded it as a collective, collaborative international effort; with a significant part of that effort dedicated to studying and combating climate change.

Hard disagree. I feel we as a species should learn to outgrow our primitive need to grow and spread our seed at any cost. When I compare it to the mentality of a cancer cell, I mean it: a cancer cell seeks to consume resources and grow and spread at any costs, even if it means the ultimate death of its host and itself. Everything you just said sounds like that to me.

We learn to be content with our boundaries here on Eden, we can end the unsustainable drive to consume ever more resources. We can learn to find equilibrium. But if we get out into space, especially with the explicit goal of spreading ourselves as much as possible? Then we're essentially dooming our species to who knows how long of an existence spent seeking more resources to consume. That sounds horrible to me.

And if an asteroid or nuclear war or whatever does end our civilization here on Earth? Then it was just our time to go. All that has a beginning must have an end, the laws of thermodynamics dictate it. Earth is our cradle; I believe it should also be our tomb. I'm at peace with that idea.

Growing and spreading and consuming resources until depletion (or until feedback through predation/disease/... lower your reproductive rate) are universal among known life. I would ask whether you're in favour of global nuclear war, but it's almost certain that enough rock bacteria will survive to eventually evolve complex life again, some of which could conceivably attempt to build rockets. Therefore, I interpret your position as advocating the construction of giant thrusters to push the Earth into the Sun.

I can understand the crux of the critique, but it's hard to take too seriously. "We as a society should not attempt ______ until we overthrow capitalism, establish a global utopia, and terraform the planet" is a pretty high bar, and not actually specific to space travel. And to my mind, space offers better opportunities for achieving those sorts of goals (asteroid mining, solar power generation, satellite infrastructure, planetary colonization, international cooperation, etc.) than anything on Earth (where the main obstacles are largely intransigent political and socioeconomic power structures, rather than technical challenges). More to the point, global public spending on space travel has always been very low - estimates place it at about $4 per person each year - it's hardly standing in the way of any social or environmental remediation programs.

This isn't ethically, morally, or logically, you're decision to make or your place to judge.

It's also contradictory. We more or less already expanded across the entire surface of the globe and live everywhere conveniently habitable for us, and though geoengineering made things mostly uninhabitable barely habitable at great expense. If we have, by definition, already expanded for the sake of expansion, and then in your words "learned to make do with our resources in a sustainable way" then why can't we expand a little further, a few extra planets, and learn to use those sustainable *and* now also have redundancy?

I get your probably just a terrible troll but at least try to be logically consistent. Like you're against (us) humans, expanding because ostensibly we displace or consume resources used by other life, but your fine with all life, human and otherwise, all dying?

The idea that your insisting on that there is a natural "ending time" for our species is just wholly inconsistent with your first principles; if one species of ants, displaces and exterminates and out-competes another species of ants, you'd be fine with this; this is a contradiction.

There's no reason to think that creatures made out of neutronium could exist. That's the realm of science fiction.

What we DO know is that carbon compounds are abundant, readily synthesised de novo in reducing atmosphere conditions, and have generating life before because we're products of that process. Ergo, the life forms we will encounter will likely be carbon-water based because if the ubiquity of those compounds and their proven ability to support life.

So why circle jerk about living rocks or self-replicating eddie currents in solar winds when we should be looking for liquid water and carbon compounds?

How is it dumb? Are you saying that it's just so obvious that a thing like a cell is physically possible and that everyone would just know that across the universe? We have been studying them for hundreds of years and we still can't make anything like them. A scientist from a planet without cells or brains would understand the chemical reactions but the idea "you can make a polymer out of carbon atoms" to 'you could make a cat out of this" is a big jump that isn't particularly obvious and takes a ton of leaps of logic on how any of that would work.

I wouldn't call it dumb really, but I wouldn't agree with it either.

I would say that yes, yes given what we know the formation of cells is obviously physically possible. A basic cell-like vesicle form easily enough in water due to molecules that are hydrophillic on one end and hydrophobic on the other. Autocatalytic RNA exists and can 'reproduce' from available nucleotides (which can form spontaneously due to carbon chemistry) and can indeed 'mutate' so that the best 'reproducing' RNA has an advantage and becomes more common that other RNA. The basic building blocks of life from lipids, sugars, amino acids and nucleotides all form readily and often spontaneously even in space.

Like we might not expect carbon based life if it was completely outside of our experience but we understand the mechanisms and reasons behind it enough to see that it's clearly possible in principle and we'd have examples of complex carbon chemistry to the extent that it'd be way less surprising than silicon, gallium, lead or tin based life let alone anything more exotic.

Put it this way, silicon based life is the most probable 'exotic' life form based on our current levels of understanding and even that's got so many issues because silicon forms weaker bonds than carbon usually except when forming giant lattices without sufficient variation to make anything much more interesting than rocks. Like even silane, the equivalent to methane, spontaneously combusts in most plausible environments.

Sure there are peculiar conditions in which slightly more complex chemistry of silicon could possibly emerge but in general it doesn't readily form things much longer than 3 silicon atom chains. Compare this with carbon and DNA strands that in humans are about 2 meters long.

Also most of those exotic conditions suitable for stable, interesting silicon chemistry involve extreme cold to help stabilize the silicon based molecules that would make pretty much every other function of life harder and most chemical reactions very slow.

e: Guessing I'm wrong about some of this, particularly having read back over some older posts but it still seems really unlikely that silicon could do the job of carbon without some really weird and specific set up.
