How long would it take for us humans to fully exploit and deplete
another planet or large moon?

Using Earth as an example, and knowing that only since the last ice-
age cycle abruptly terminated as of 11,712 years ago (as a timeline
starting-point), would suggest that at the outside most another planet
or moon could manage to survive our advances and fulfill our needs of
mass consumption is roughly 10,000 years. *However, further
considering that we’ve only recently advanced our rate of
overpopulation and mass consumption with nearly total disregard as to
the environment and its biodiversity within the last thousand years,
as such might bring that off-world survival timeline down to a more
realistic span of a thousand years, or 50 generations before the
surface of any new planet or livable moon is systematically maximized
to death (assuming a similar composite surface and seasonal tilt as
Earth along with hosting numerous proxy wars).

This means we’ll not only need to discover and populate another
Goldilocks certified planet from time to time, but that other planets
and moons will have to be continually lined up as each new planet and
moon gets overpopulated and consumed by a infestation of humanity that
knows no bounds and has no remorse whatsoever for any consequences of
its actions.

Of course, if we’d just discovered a suitable other Earth 2.0 as of a
century ago, *and of knowing what we can easily accomplish with our
existing bigotry, greed, insider trading and proxy wars, could easily
bring our next oligarch overlord dominated planet to its knees, as
traumatized past the point of no return within as little as a century
if the various faith-based and political rivals get to speculate,
insider trade and essentially do as they please regardless of whomever
we the republic elect or appoint.

Ideally, what we need to discover is a very large planet of 9800 km
radius with somewhat less density of perhaps averaging 3.5 g/cm3, so
that surface gravity is similar or somewhat less, and the surface area
is worth perhaps twice that of Earth, however for several reasons it
would be nice having at least twice as much atmospheric density.
Otherwise, each new planet or moon that’s Goldilocks approved would
have to be restricted as to accommodating only a few fully compatible
groups of humans that have most everything in common.

Secondly (as our plan B), in order to hold onto whatever terrestrial
resource remainders and survive within the GW/AGW consequences we have
at hand, whereas instead of our migrating to another planet or
habitable moon of a gas giant or brown dwarf, we could simply relocate
our moon, as to station-keeping within the Earth L1 halo orbit. *This
would require some complex logistics of orbital expertise and applied
physics, as well as always forward-thinking which is actually hard to
come by nowadays, especially when moon relocation is not going to be
any geoengineered quick fix. *Of course the use of TBMs in order to
excavate and tunnel inside as to establishing a vast number of human
complex habitats, would make even our little moon as perfectly good to
go for many thousands of years, and this effort of moon relocation
would also eliminate our out-of-control GW and more than offset AGW
issues, as well as cut our ocean tides by 50% and reduce seismic plate
tectonic issues by 75% (thereby saving the infrastructure and
biodiversity of Earth at the very least 0.1 trillion dollars per
month, or a full trillion per month in 2050 dollars) by figuring on
Earth hosting ten billion humans, and essentially not enough of
anything to go around.

Ignoring what our moon and the extremely nearby planet Venus has to
offer, is exactly what the mainstream oligarchs in charge want of the
rest of us. Apparently, the only thing that matters is sustaining
their mainstream status-quo w/o revisions. Such a pity when the brown-
nosed minions get to topic/author stalk and trash these public Usenet/
newsgroups (unmoderated newsgroups like alt.astronomy), keeping K-12s
and anyone else they can intimidate and even terrorize at free will.

No wonder this nation is becoming such a lost cause, and future
generations are already destined to being past the point of no return.

For those few willing and brave enough to read and contribute to this
and other public topics, you need to be aware of what the motivations
and hidden agendas are of those disrupting and even hijacking our
topics have at risk. If you can't deal with this intellectual
terrorism gauntlet imposed by those trashing Usenet/newsgroups, then
perhaps you have no business reading or contributing to anything, much
less edgy stuff that needs an open mindset. If you can't
independently think for your self, you might as well give up and just
parrot or robot your way though whatever life these oligarchs have
planned for you, and do it with a smile.
