| Apr 1, 2021 at 14:41 | comment | added | chiggsy | @chasly-supportsMonica There's a forseeable apocalypse in progress right now that will make the Earth unliveable in a couple hundred years. We won't even commit to lukewarm showers. I must admit, I kind of wish I lived on your Earth, with the humanoids who support such actions so unilaterally. Hmm. Maybe not. | |
| Mar 29, 2021 at 9:28 | comment | added | chasly - supports Monica | @chiggsy - "How are you going to justify pouring Earth's resources onto a lifeless planet?". There is a foreseeable apocalypse on the way that will make Earth unliveable for a few thousand years. | |
| Mar 29, 2021 at 3:48 | comment | added | Loren Pechtel | The pressures equalize. Since the Moon's gravity is 1/6th of ours the atmosphere will be 6x as deep. | |
| Mar 28, 2021 at 2:32 | comment | added | chiggsy | Antarctica definitely is the best place for the portals, since a significant fraction of humanity will be coming to stop you from doing this. Crater lakes? Why? You have a wormhole, why not start with a flat on the moon? How are you going to justify pouring Earth's resources onto a lifeless planet? Low gravity means quality of life will be substandard at best, right? You can't give the moon a magnetosphere, so the solar wind will rapidly alter what you steal to something unlikely to be habitable, surely? How will you deal with the hard radiation sleeting in from the sun? | |

| Mar 27, 2021 at 16:23 | comment | added | chasly - supports Monica | @PcMan - As I said, 10 meters diameter. If necessary there can be multiple portals. The main problem will be where to put them in order to avoid local damage. The best place would probably be Antarctica. Powering the portals requires a lot of electricity but I plan them to be self-powering turbines. As the pressure differential lessens, the portals will blink shut one by one. The final few will have to be powered externally. | |

| Mar 27, 2021 at 16:09 | comment | added | PcMan | HOW LARGE is your portal? Even if it is 1 kilometer wide, and pretending that the moon side stays in vacuum, it will take 82 years to move enough air to equalize pressure. In reality, pressure will never equalize, as the ever-reducing pressure differential will slow down the rate of movement. If your portal is just 10m wide, it will take more than a million years to move just half of the needed air. Not exactly "super-fast" as requested. | |
| Mar 27, 2021 at 15:30 | comment | added | DWKraus | Regardless, you might want to dump your gasses into some kind of tunnel system where the velocities of the gasses can be reduced. The air coming out of this thing will be like a titanic tornado on steroids or a constant explosion. Otherwise a lot of gasses would simply be blasted into space like a cannon, with no chance to get deposited on the surface. | |
| Mar 27, 2021 at 15:19 | comment | added | DWKraus | It might be cooler to open your portal on Venus, and fill the moon with CO2 from there. You don't really care what happens to Venus, and the CO2 will be able to get converted to carbon products and lots of oxygen. The moon wouldn't have all the Venus issues with the atmosphere, and it would be a very greenhouse gas mix to help warm the moon. Not sure if the sulfuric acid would all precipitate out right away at lower temperature and pressure. But if you can open portals, why not on Venus? | |

| Mar 27, 2021 at 14:34 | comment | added | chasly - supports Monica | @MolbOrg - 10 meters diameter | |

| Mar 27, 2021 at 12:05 | comment | added | notovny | This is going to take a not-insignificant portion of the Earth's atmosphere. Not enough to kill people outright, but enough to seriously mess with Earth's biosphere and weather. | |

| Mar 27, 2021 at 11:41 | comment | added | Pelinore | I assume this portal does open onto the surface of the moon rather than into sealed caves or domes? | |
| Mar 27, 2021 at 11:26 | comment | added | Pelinore | @StarfishPrime "Shouldn't be too hard to answer", I thought. And now" lol | |
| Mar 27, 2021 at 11:26 | comment | added | Starfish Prime | @Pelinore the rate of atmospheric escape will be negligible in the near term (on the scale of at least centuries). | |
| Mar 27, 2021 at 11:25 | comment | added | Starfish Prime | "This looks like an interesting question, and shouldn't be too hard to answer", I thought. And now I seem to be drowning in differential equations. | |
| Mar 27, 2021 at 11:25 | comment | added | Pelinore | I don't think your pressure will 'equalize', gravity is going to be a factor, it's downhill to Earth from the moon through your portal & the moon hasn't enough gravity to hold the same atmospheric pressure, not sure how that's going to interact, someone else is going to need to do your math there though. | |
