Similarly, if you see posts along these lines, do not engage. Report them, block them, and live a happier life than they do. We see too many slapfights that boil down to "Mom! He's bugging me!" and "I'm not touching you!" Going forward, slapfights will result in removed comments and temp bans to cool off.

We ask that the users report any comment or post that violate the rules, to use critical thinking when reading, posting or commenting. Users that post off-topic spam, advocate violence, have multiple comments or posts removed, weaponize reports or violate the code of conduct will be banned.

All posts and comments will be reviewed on a case-by-case basis. This means that some content that violates the rules may be allowed, while other content that does not violate the rules may be removed. The moderators retain the right to remove any content and ban users.

Scientists have for the first time discovered a cave on the Moon.

At least 100m deep, it could be an ideal place for humans to build a permanent base, they say.

It is just one in probably hundreds of caves hidden in an “underground, undiscovered world”, according to the researchers.

Countries are racing to establish a permanent human presence on the Moon, but they will need to protect astronauts from radiation, extreme temperatures, and space weather.

Helen Sharman, the first British astronaut to travel to space, told BBC News that the newly-discovered cave looked like a good place for a base, and suggested humans could potentially be living in lunar pits in 20-30 years.

At least 100m deep, it could be an ideal place…

Seems excessively very deep to me - someone’s going to have to build a freight elevator as tall as a soccer field is long. Even worse, I’d expect you’d want your airlock on the surface so you’re not struggling to maneuver in a bulky suit just to get outside: now you’re talking about a 100m pressurized elevator.

Does anyone know how deep you’d ideally want? I’m sure NASA has studied it. I do remember reading that 1’ is the exact wrong number because of indirect radiation. While you get more protection from radiation and a more stable temp, the deeper you go, the marginal value probably drops off pretty quickly, plus the inconvenience would quickly climb. When people online talked about living underground on the moon, I always imagined like 5-10m

Edit: here’s an argument to keep it less than 12m deep

Edit2: and here’s an argument for at least 1-2m
