beachbaby Posted January 3, 2018 Posted January 3, 2018 What if we were able to build mini-Earths and have them orbit around our planet Earth... How could we achieve this? All ideas, any ideas would be very helpful. Thank you.

Are suggesting enclosed habitats?

Are suggesting enclosed habitats? Sure, enclosed habitats would be fine. But is there a way that we could make an artificial atmosphere? I'm really interested in any possibility of making this mini earth. What ever it would take.

Pipe in sunlight and then spin it for artificial gravity. https://en.wikipedia.org/wiki/O'Neill_cylinder My personal choice is a rotating torus but the principle is the same.. https://en.wikipedia.org/wiki/Stanford_torus Edited January 3, 2018 by Moontanman

The rotating torus sounds like a good strategy. Do you know where I could research how to build this? and what about the sunlight. This is very new ground for me and is something I got curious about. Thank you for taking the time to share your thoughts with me.

This one addresses that very topic. 1

Just to be clear, there are no thoughts on how we can recreate a mini big bang and start a planet with its own resources that creates its own life while creating an artificial sun for it. And then possibly accelerating the planets growth process somehow to make it less primitive...

If you wanted another planet and you had the energy reserves for that you could do much better than mini earths. A dyson swarm would allow you to support trillions of people, no new technology really required, just lots of money and time.. Edited January 4, 2018 by Moontanman

Gotcha, any ideas on the cost for this thing? everyone just keeps saying that it is a phenomenal amount of money, but no estimated numbers...

Depends really on how fast you want to do it, but once you have the infrastructure in place the actual habitats should be relatively reasonable. There is no way to estimate not knowing what type of economy we will have when we start building a dyson swarm. I can see small groups or even individuals owning smaller tori to whole nations owning larger ones. Maybe they will have a used habitat lot like a used car lots we have now...

It is an odd thing to think about, used habatat lots, repo an old one or trade one in one a fancier model. Expose the inside to vacuum and sterilize it... Do you know of any reason the OP can't post here anymore?
Janus Posted January 4, 2018 Posted January 4, 2018 You could get this book: Though it is a bit dated, having been printed in 1972, and will run you ~$60.00 used on Amazon ( and no, you can't have my copy.) 2

I actually rescued my copy from a bunch of books that were being withdrawn from a library back in the mid-eighties. So it would depend on whether any libraries have held on to their copies and not withdrawn them. I also have a college physics text book printed in 1916 and copyrighted in 1910, and a 1936 textbook on Atomic Physics. Both were withdrawn from our State Library. 1

I like old books too, I don't have any rare ones but i still have my high school geometry book. I reference when ever i have to figure volumes and distance.. 35 minutes ago, StringJunky said: It's been prepared and released by NASA for the internet: Space Settlements: A Design Study (Table of contents) Interesting link, it is somewhat dated but information is always important. I wonder how much of an actual game changer things like Carbon fiber, nanotubes or graphene would be?

Dang I only have a 1912 physics textbook lol

I knew that it had been printed and that I had owned a copy, but wasn't sure at first if I still had it. (Due to limited room, I've been forced to down-size my book collection from time to time.) . I came across the Amazon listing first, and when I saw how much it was going for, I got sidetracked and had to physically search through my bookshelves. As it turns out, it had survived the purges.
