Won't dreams stay dreams?

There's literally nothing there, why go all that way? The distances are so incredibly vast. It seems like we ought to be content with staying put.

All life on Earth is going die. Humanity has never been content with staying put, why would we start now? And what do you mean "literally nothing there"? The universe has a loooooot of stuff in it.

In fact, technically, there's nothing here. It's all out there.

The Sun: 99.86% of the solar system's total mass.

Jupiter: ~0.095% of the total mass, and ~71% of the non-solar mass.

Saturn: ~0.03% of the total mass, and ~19% of the non-solar mass.

Uranus and Neptune: Contribute a small percentage to the remaining non-solar mass.

All other objects: (inner planets, dwarf planets, moons, asteroids, comets, etc.) account for less than 0.002% of the solar system's total mass.

Your brain mass is about 3 disposable water bottles in weight and we can debate what parts of that are thinking and actually "you".

You are insignificant on the scale of the solar system let alone the universe.

For whatever reason, humanity's attitude in this regard has changed drastically in the last century. We can't even bother to make the next generations, and a shrinking population eventually (quite quickly, really) shrinks to zero. Not only do they want to "stay put", they want to lay down and die.

It's mostly empty, isn't it?

By "literally nothing there," I mean there's literally nothing for us. Three stars and a few Earth-sized planets in the habitable zone that are, more than likely, uninhabitable by humans. There's nothing there worth going all that way for.

I like sci-fi as much as the next person but the reality of the situation, it seems to me, is that the universe is mostly empty, vast, and inhospitable to human life.

To quote Babylon 5

Ask ten different scientists about the environment, population control, genetics, and you'll get ten different answers, but there's one thing every scientist on the planet agrees on. Whether it happens in a hundred years or a thousand years or a million years, eventually our Sun will grow cold and go out. When that happens, it won't just take us. It'll take Marilyn Monroe, and Lao-Tzu, and Einstein, and Morobuto, and Buddy Holly, and Aristophanes, and - all of this - all of this - was for nothing. Unless we go to the stars

>Tragula's wife used to complain to him about the utterly inordinate amount of time he spent staring out into space, or mulling over the mechanics of safety pins, or doing spectrographic analyses of pieces of fairy cake. She would often tell her husband to have some sense of proportion, sometimes as often as thirty-eight times in one day. In response to her pleas for him to find some perspective, he built the Total Perspective Vortex.

>Into one end he plugged the whole of reality as extrapolated from a piece of fairy cake, and into the other end he plugged his wife: so that when he turned it on she would see in one instant the whole infinity of creation and herself in relation to it. To Trin Tragula’s horror, the shock completely annihilated her brain...

The odds are against us. We will never go to the stars. But it doesn’t matter for us as we will likely die before any of this happpens.

The steelman counterargument is that focusing resources on extraplanetary colonies at the expense of the one habitable planet within reach will hasten humanity's destruction. How are you going to make an Eden on Mars if we can't even make an Eden on Earth? The only large-scale planetary engineering in humanity's history is Veniforming its home world.

That doesn't seem like a strong argument to me. It seems like a distraction from the crowd that would save the planet by extinguishing humanity if that's what it took. Though what value the planet might have with all of us gone I leave as an exercise for the reader.

The first priority of any society that wants to continue to exist into the future must always be to make the next generation. If you do not do this, or if you just leave the task to others hoping that someone else will do it, then you are behaving in a way that will in all probability lead towards there being no next generation sooner or later. The "global warming is the apocalypse" movement constantly talks about how the best way to reduce your carbon footprint is to have no children.

>The only large-scale planetary engineering in humanity's history is Veniforming its home world.

So it is claimed, but from my point of view it looks very much as if it's intent on making itself extinct through fertility decline. But at least carbon dioxide levels will return to normal, eh?

Well true.

That's the fallacy in the given argument.

So is the Pacific Ocean for practical definitions of emptiness. You don't got to the empty places.

The difference between a multi-generational interstellar ship and a self-sustaining space colony is the engine. They wouldn’t need inhabitable planets - they would need raw materials to build more ships and habitats.

I’m not sure that after spending a lifetime in an ample space colony its inhabitants would feel nostalgic of the time we spent sitting on round rocks cooking around a star.

By then we’d better understand how to implement a “Let there be light” procedure.

Might very well be the last question we need to ask ourselves.

Happily when Asimov wrote the same story, he didn't give away the punchline in the title.

Sure, if you put it in the title you need a different punchline. :D

It would be a different tale altogether - probably engineers discussing how ludicrous the idea is, until it's feasible, and then debating the consequences before pressing the red button.

Yeah. I think I was really imagining it as a chapter title in something like Ra [0]. Sam is good at bombastic chapter titles.
