Couple of centuries away for a REAL Colony. SciFi colony – oh yes straight away sir, real colony another matter.
As a reader in search of the details go no further than viewing the video copy of a public lecture at the Perimeter Institute of theoretical physics at Waterloo Ontario Canada where Neil Turok is the chief cook & bottle washer (Mr. Turok, born S. Africa, lived a while in Tanzania & went to Cambridge U was just made a recipient of the Order of Canada.)

I think that human life on Planet Earth will survive this much talked of 6th. extinction with all the clever developments by those researchers we are lucky to have so don’t worry (well not too much). I think we’ll get by and sustain here but we also need to colonise as soon as possible.
We will worry though. It’s what humans do.
Earth is but a small Solar star planet on the wing of one galaxy in the Milky way galaxy of stars.
There are many more stars in the Milky Way galaxy & the Milky Way is but one of the galaxies in this Universe. There may be more Universes. We don’t know.
All matter as we define is Cosmic Matter. Ergo I am including all matter. (Brave!).
With all that territory we say there must be other life. Alien life. So far we haven’t found any. Don’t feel bad for as we will come to see there are many reasons.
We have & will be obsessed with Planet Earth which for a while to come will be our home but we will now start to include posts on Cosmic Matter.
Quoting Oliver Hardy “Another fine mess you’ve got us into”.
It’s this oft use word “Sustainability”, always referring to life on planet earth, about which we are assumed to know the meaning while I have shown that no one can without including also the terms.
To eliminate the mess I intend to always state the CURRENT terms which (boringly) the reader MUST include.
Rare Elements found on planet earth are not renewable resources. We either have them handy or we simply don’t have them. We need them in the future to survive & we are finding them difficult to get. This aspect is aside from all the noise about population size & global warming.
Energy is pouring onto earth abundantly (hurrah) & unfortunately a lot of it at times when we don’t use it (oh dear). The common lead-acid battery is not the answer & much faith is being placed on batteries with vanadium poles. We need energy. We need abundant supplies of rare elements such as vanadium to build useable batteries (that we have yet to invent).
In a much commoner case the non-renewable rare element chromium is used to coat steel (e.g. car bumpers). We are currently gobbling up chromium element & urgently need to find more.
Not easy additions but still workable are our exploring the much neglected sea bed source & the rich source of solar system meteorites. Neither are renewable resources but resources that could supply our needs for some time. Also there are the possibilities of using the ever resourceful scrap dealers more than we have done yet.
Not a very nice post is it. Rare metals resources are a stand alone issue to solve as we deal with all else if we are to be humans on planet earth.
There are though possibilities…..
Our clever researchers may get some from seawater Seawater Source
They may find ways to get some from Asteroids & Meteorites Valuable Asteroid
Don’t rule out some (a little) from scrap merchants!
A sustainable population is one that can be maintained at that number of people indefinitely without adversely impacting the environment or the quality of life of the members of that population. (Answers.com)
One that can be maintained at that number of people indefinitely without adversely impacting the environment or the quality. (Eh?). True enough PROVIDING EVERY COMPONENT REMAINS UCHANGED. Otherwise we look at a FALSE number, one that changes by the day & is only true on that day.
Faced with Artificial Intelligence, Quantum Entanglement (which nobody understands, don’t let them kid you) I ask where next.
NEXT is a common element to the series. Why? because Times They Are A’Changin fast, fast.
As yet there are NONE. Surprise-Surprise. It’s true that resources we know about are valuable, irreplaceable & current use cannot be sustained. BUT we can expect our clever researchers to find more useable unrenewable resources on places as yet unexplored like the seabed & asteroids (spot the gleam in my eyes).
MOVE ON & SAY HURRAHS
