Hehe. It didn't work on earth so you suggest we should try it where the practicality is near zero?humankind may be able to live on the surface of Mars under a protective bubble.
You might wish to consider something that isn't just a useful and practical corridor to the outside world as an example.Thinking of this
We have a head start. There is a city somewhere in Canada where they spend most of the time underground in the winter.
Is there 0.13% oxygen like on Mars?
It didn't work on earth
Where and when did people live under a force field bubble on Earth I wonder?
I thought that technology was purely speculative fiction: https://en.wikipedia.org/wiki/Force_field_(technology)
Perhaps you should reread my post.
No force field bubble, there is no such thing.
There was Biosphere 2, back in the 90s.
More recently, a NASA experiment.

Remove the 'force field' part that is not required on earth and stick to the bubble part. An eco-terrarium is just that. This is not a case of instant adaptation, this is attempting to force evolution. There are reasons this type of captivation is not welcomed by human nature.

Perhaps unfairly, Biosphere 2 (so named because Earth is Biosphere 1) became the subject of ridicule and late-night talk show jokes.
The project was inspired by the work of architect and theorist Buckminster Fuller, who popularised both the Geodesic Dome and the term 'Spaceship Earth'.
Somehow the underground shopping malls of Toronto and Montreal have become the argumentative basis for space exploration. Idiots. BTW nobody in either of those cities is spending even a majority of a 24hr day underground.
Ripple in space time is gravity. An apple falling off a tree causes a ripple in spacetime.
Boring.

While the engineering challenges are interesting, they are not the biggest obstacle. I remind you that the longest time any human has spent outside of Earth's gravity is 12 days, all the while the reassurance of Earth's appearance in view, and a comms delay of less than a second. The comms delay on Mars is about 20 minutes and Earth is invisible. Human minds would collapse long before any successful mission.
This thread is an amusing case of not seeing the wood for the trees 🥹
Well, not unless you got a Bachelor pad with a system that seems to have JBL L100, Phase Linear amps, a Revox reel to reel, a 7.1 channel surround with a 140" OLED screen... ( speakers will sound like Harbeths and the amps will be XS300 in disguise)... the Revox will house an RME AD/DAC.
And a few chicks... lots of Courvoisier ( actually Bas Armagnac in a Courvoisier bottle ).
The radioactivity would never penetrate a mine some thousands of feet deep. And in a matter of weeks, sufficient improvements in dwelling space could easily be provided.
Regrettably, yes. But it is, you know, a sacrifice required for the future of the human race. I hasten to add that since each man will be required to do prodigious... service along these lines, the women will have to be selected for their sexual characteristics which will have to be of a highly stimulating nature.
Mr. President, we must not allow... a mine shaft gap!
In Mars, of course! 😵 😀

And became The Matrix. Humans still exist, but have gone underground.They create AI and are replaced.

Well, I can attest that the underground Path is a great way to get around downtown when there's a blizzard out. Speaking of which, staying underground seems like a good idea when it's -95C out, too! 😉Somehow the underground shopping malls of Toronto and Montreal have become the argumentative basis for space exploration. Idiots. BTW nobody in either of those cities is spending even a majority of a 24hr day underground.
I'm not sure where the idea that humans can't exist underground or in isolation comes from. Humans are a most adaptable species, limited only by the effects of an alien Nature on our biology. We may yet be able to adapt to that as well, given time, technology and evolution.
The psychology of isolation is well understood.
As is technology to obviate the effects of low gravity,
I see no real difference between living in a soil shielded cave/dome on Mars and living in a plywood and foam dome during an Antarctic winter and that we have been doing with reasonable success for many decades now.
I think we could handle the engineering challenges very soon, and as animals we humans do seem to be reasonably adaptable.
The communication time gap is nothing compared to the communication gap 200 years ago and we seemed to cope back then.
Personally I won't want to go, I like it here but I'd maybe want to move to Habitat Prime.
There is something about the idea of a Space Station 200 kilometres long and 50 kilometres in diametre rotating just fast enough to give an approximation of Earth gravity that appeals to me
Thank-You Freeman Dyson
