Interstellar Flight: Perspectives and Patience

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.

There was a time when there was nothing (European) in the entire New World. There was a time when there was nothing known (to the US) about what was in most of the Louisiana Purchase. There was a time when there was nothing (European) in, say, Ohio. And then Nebraska. And so on.

There was literally nothing there? Why go all that way? To see what was there. And then to make something there.

[Edit, because I'm rate limited: No, interstellar space is something to cross, to get to stellar space. You think the New World was rich? How about a whole solar system of untapped resources?

That's why people will try to go.]

They didn't believe there was literally nothing there. They went all that way to find unclaimed riches.

The hypothetical riches were quite obvious: same stuff we have over here, but not owned by someone yet.

What are they hypothetical riches of outer space?

This is a question we should think about clearly and logically without resorting to stuff like "oh tally-ho the adventure!" type nonsense.

There is many times more water in gas giant moons than on Earth. If we develop the technology needed to make a multi-generation ship we also have the technology to make deep space habitats - enough for trillions or quadrillions of people.

Just imagine the economic output of a civilisation a million times the size of ours.

It’s a lot easier to imagine the economic output of simply raising all of the current Homo sapiens out of poverty and into economic productivity, no?

Then we can use all of that new productivity to start working toward the next rung?

Our economy is not currently throughput limited on water or space so I don’t find this compelling.

These people are dreamers that grew up watching Star Wars and Star Trek. The world painted by those shows has lodged in their minds, and no amount of logic will shake it loose.

In the past, I've challenged the "Let's colonize Mars!" people to do something that's far easier: Move to Bouvet island, now.[1]

This is a frozen uninhabited rock that is nonetheless a tropical paradise compared to Mars. It's far easier to reach, has free unlimited oxygen and water, and gets more solar radiation also for power! It's luxurious compared to the colder, dryer deserts of Mars where there's only dry rocks and near-vacuum.

If you really want to spice things up, donate $10,000 to a charity per pound of material you take to the island (what does a shelter weigh?), take 100% of your food and water with you, and never go outside without wearing full scuba gear. For "realism mode" sprinkle a small amount of radioactive powder evenly everywhere around your habitat area.

"Yay! Adventure! Honey, tell the school we're unenrolling the kids and taking them with us to this wonderful opportunity to start a new life!"
