In the place where the Apollo 11 mission took place in 1969, they discovered a cave on the Moon that will be perfect for sheltering humans in the future. There, humans can be protected from radiation, temperature, etc.
Now just imagine: a human civilization living inside the Moon for years and conducting studies in there. Very good, right? Because this may be possible in 20 years. All of this was only theory before, but an Italian study proved it to be true.
