"It will be difficult enough to avoid disaster in the next hundred years, let alone the next thousand or million." "Our only chance of long-term survival is not to remain inward-looking on planet Earth, but to spread out into space." - Stephen Hawking
Many scientists believe that it's too late to save our planet, and that all we can do is prolong its death. They suggest we leave Earth - but there are a number of engineering challenges involved with leaving Earth en masse that have not been addressed.
How do we get a significant portion of the population off Earth?
- People should be intact and alive
- People should not be genetically or cybernetically modified
- "Significant portion" means at least 1 in 1000 people still alive by the time your project has been constructed. You can choose specifics about the people chosen but they should be diverse, from a range of countries. Assume they can be transported to anywhere on Earth.
- "off Earth" means low-Earth orbit. Another question will address where they go from there.
- Money and time are not constraints, but the cheaper and quicker is better
- Assume modern-day technology exists at the start of your project
