Thousands of people could be living in floating space colonies orbiting the Earth in 20 years’ time, according to the head of a project by the British Interplanetary Society (BIS).
And, while life in space might sound unappealing to some, Jerry Stone believe it could actually be healthier than planet Earth, enabling people to live longer and, eventually, grow taller.
Mr Stone, author of the book One Small Step about the moon landings, and other members of the BIS have been updating research carried out in the US in the 1970s into how humans could start living in space in large numbers.
In a speech in Aberdeen as part of British Science Week, Mr Stone will claim humanity is now close to the point where such colonies could be built using material taken from the Moon and asteroids.

I'm pretty sure someone made the same claim in the 60s and every decade there after.
Far from plate tectonic boundaries, the average increase in temperature is about 25 C per kilometer. Don't forget, there's molten rock 25 to 50 km down, everywhere on Earth.
The heat comes from radioactive decay in the Earth's interior.
Mars's atmosphere is about 100 times thinner than Earth's. Without a "thermal blanket," Mars can't retain any heat energy. On average, the temperature on Mars is about minus 80 degrees F (minus 60 degrees C). In winter, near the poles temperatures can get down to minus 195 degrees F (minus 125 degrees C). A summer day on Mars may get up to 70 degrees F (20 degrees C) near the equator, but at night the temperature can plummet to about minus 100 degrees F (minus 73 C). Frost forms on the rocks at night, but as dawn approaches and the air gets warmer, the frost turns to vapor, and there is 100 percent humidity until it evaporates.
Core temperature. The moon has an iron-rich core with a radius of about 205 miles (330 km). The temperature in the core is probably about 2,420 to 2,600 F (1,327 to 1,427 C). The core heats an inner layer of molten mantle, but it's not hot enough to warm the surface of the moon.

And some people wonder why "experts" don't hold that much credibility with so many people. I will guarantee these "experts" are dead wrong, but I'm not an "expert", so please don't listen to me.

That is one way of looking at it and there are others.
