my comment - 1. You cant extend the size of the Earth (house)
As Mark Twain (very bad stockmarket player in the name of Samuel Clemens) once said:
Buy land - they aren't making anymore of that.
Troubles about maths.
Troubles about population growth.
Population grows exponentially.
Colonization of outer space can only increase geometrically in 3-d space.
No matter how, we still lose eventually. Math is inexorable here.
*Something ELSE has to happen"
and that something is the lowering of the potential standard of all of us living free.
BTW, if you want to visit those distant galaxies? - the time is NOW. They are moving away from you even as I type.
