More hypothetical planets to further waste dwindling resources, dreaming for 'a solution' (escape, from, for 'a few') to the effects of our earthly behaviour; we cannot even cope with terrestrial virus ...the first job on any new planet (hypothetically, but 1-1 odds) would be, we'd lumber about killing everything we could ..just in case it wanted to stop us paddling, or some such excuse ...it's us that needs changing, not the planet.

You want stability? You won't find any at Centauri. Any planet around either A or B is subject to wild perturbations of its orbit by the heavy presence of the other star. Orbits in such a system are so unstable as to be basically unpredictable. Heller and Armstrong are certain to know this; they're just having fun.

This is very exciting speculation. Exoplanets that are either 10s of light-years away or are barren aren't going to be important to us, but a potentially "super-habitable" planet next door is something we could potentially visit.
The previous commentator moaning about supposedly "dwindling resources" and the evil of mankind is a perfect illustration of how closely the Green position approaches mental illness. Reading such human-hating dysphoric drivel has only negative effects. His points are not just wrong, they're aimed at spreading his diseased worldview and making everyone as miserable as he is.
Ignore such anklebiters and marvel at the possibilities the universe has to offer. Life is not just Earth, our perspectives are going to widen unimaginably with the discoveries of the next few centuries.

Fascinating article David thank you! Just to let you know, moons have feelings too... I just checked in with Jupiter’s moon Io about your "volcanic Hell Hole" slight. Lo has been deeply hurt by this...

At 4.22 light years away and 25.6 trillion miles we aren't going to be visiting anytime soon.

Interesting as such speculation always is, the article sounds more like a Terraforming wish-list than anything based in/on/around actuality.
Of course, without speculation, we might never have left the trees, and maybe someone will be inspired enough by this particular vision to invent/work on something that makes the detection of any such planets possible --- but this feels too nebulous to me at the moment.

Well, perhaps that mathematician in Mexico back in the 90s might have figured a way to exceed the speed of light by riding one of the lesser neutrons or whatever it is called, if they have not already done that since. Our government isn't telling us anything these days.

Where is your space ship that has odometer readings in "light years?" Where is your big lunch box that will last for that distance? Will you die of old age before you get there? Enjoy your trip. I have to get back to the real world.

The imaginings of the "not real" world are what drive the workings of the "real" one. May we all soon remember.

Life imitates art. Coincidentally, I believe Alpha Centauri was the destination and planned new home of our space-faring nomads in the '60s TV series 'Lost in Space'. Of course, that may be the only scientifically correct item from the show, what with the 'hot' comet that threw them off course in the first episode. :-/ (Although, I always wanted that jet-pack!)
