Default Sedna, space probes?, colonies? what's next?

Which you know because?


Population is mathematical. Since 1800, we have abundant data points that
define the S-curve. It climbed slowly, picked up fast in the XX century, and
is leveling out now. Estimates are that it will flatten out around 10b before
2100.


Er, 10 billion isn't double 6 billion.

Also have you seen the size of the error bars on that thing?
http://esa.un.org/unpp/
7.4 billion 2050 (low) [Already past peak and going down]
Also 8.9 billion 2050 (medium) [Going up a bit over 0.1 billion / 5 years]
10.6 billion 2050 (high)

Unless of course it crashes before then.


So in other words you don't know it will get there.

10b before
2100.

Close enough as makes no nevermind. The error is only 16%.

[thank you for the link]

No, but if it does crash, that will be because of some near-final catastrophe
between now and 2100. A world in which the P has crashed, is probably one
without a desirable future. So we have to assume it won't.
