This is not true. No amount of space suffices for exponential growth.
Hubble length is less than 10^24 km. Earth radius is more than 10^3 km. Therefore there's at most room for 10^21 growth in one dimension, 10^63 growth in three dimensions. 10^63 growth is less than 210 doublings. Doubling is less than 70 years of 1% growth per year. 210 * 70 is less than 20,000. Therefore, we can't grow more than 20,000 years, 1% growth per year.
- ekianjo 12y agowho talks about exponential growth ? Ongoing growth can be linear and has no need to be exponential. Nice strawman.
- collyw 12y agoThe way politicians describe growth, it is implicit that it is exponential. More people, producing more offspring, living longer, and using more resources, as more of them become middle class.
