hmmm, i'm impressed that you knew that twink. good work!


How absolutely silly


does absolute silliness have a numerical value?

of yourself, and proof-positive of what rusemasters

you folks actually are.


well yes, the twinker and myself are behind the plot to convince the
public
that the moon is migrating outwards with each passing year. we almost
had
you all fooled.


Before we blindly leap ourselves onto our moon (for the first time),
perhaps we should think again. You folks have got to be absolutely
kidding about utilizing the physically dark surface of our extremely
dusty and highly reactive moon, especially for much of anything that's
on behalf of optical astronomy.


aren't you the guy who thinks there should be a colony on venus? now
that's
crazy!



Why is it cracy? There are only a limited amount of living space on
this planet Earth. At the rate earth's population is growing, we
should set our sight into Venus or Mars. Our scientists today should
be studying these planets to see how we can make it liveable for human
beings.


Who's lining up?

There are people who are willing to live on Mars even as is it. Many
more would likely be interested, if it could be quilckly terraformed
into something passably Earthlike.

Is that subset of people, though large, a signifigant fraction of
Earth's population? No.

No matter how bad things might be here, most humans don't want to
emigrate. Will you force them? Which ones, and how? And even if they did...

What would they ride?

Even if you could make travel to Mars as cheap as intercontinental air
travel is today, and had the same number of spaceships, with the same
capacity, as all existing wide-bodied jets, can you even remove people
*fast enough* to keep up with population growth? (and will they continue
to breed after arrival?)

I don't have numbers, but I seriously doubt it. (and there's still
that willingness issue, and I'm completely ignoring the questions of
what to do with them on arrival, or if it's ethical to terraform Mars if
there's native life)

There may be a great many reasons for space colonization and
terraforming, but population relief's the least likely or practical one.

And anyway space colonization even thoretically is at best a delaying
action but no solution.
Proof:
Assuming a steady exploration speed limited by the speed of light,
The available volume of space for colonization (i.e. size of the sphere
centered on earth) grows at most as r**3. i.e. the volume grows
algebraically.
Population growth is exponential.
And eventually any exponential rate 0 will surpass any algebraic
rate.
