Could the Moon be almost like Earth? Just think of it,,Suppose Moon was our little earth? Oh boy we could just grow food on there and ship it back to earth.

I should've said mass instead of density. Other part's right though.

Look Popluation is getting to be a problem today. It took over a million years to get 6 Billion people on planet earth. So if we go to a bigger earth it can hold up to 18 billion people and that will take 3 Billion years.

You should know that when I was born there was less than 4 billion people on the Earth. That means we've had an increase of more than 2 billion people in the span of 42 years.

So where are you getting the idea that it'll take 3 billion years to go from 6 billion to 18 billion people if the Earth was twice as big?

No, no, you're fine. It's other posts that make me .

Yes, the moon could be terraformed. It would take approximately 10,000 years to loose it's atmosphere unless replenished on occasion.
