For now, here is a little insight into FERMI ‘s PARADOX :
In the middle of XX° th century, FERMI, the famous physician, calculated the probability we can see extra-terrestrial civilisations through signals coming from a progressfull, industrial civilisation like ours. Result was not in line with the fact we see NONE.
He asked himself the clever ones’ question : ….WHY ???
He eventually proposed these civilisations SELF-DESTROYED THEMSELVES ANYTIME !!!
Think about it clever ones . Think about it . Please Do.
Poutine, in september 2015, UNO speech did not only announce russian war in Syria. He also stated world civilisation had to find a way to bridge something between what he called himself : biosphere and technosphere.
He asked : If there is one on this planet, Russia will be happy to work with. I am confident there is one….
The truth is : there is not.
He asks too much too bridge.
May be after a demographic crash to 3 or 4 billions… in certain sparse energy conditions… (I once calculated that…)
But, knowing mankind, that would mean SLAVERY for most.
Around 1 billion, LIBERTY as we wish would be just POSSIBLE. But more you ask, less are the chances you get freedom on this planet.
We can rebuild or maintain very important infrastructures like telescope, sky observatories, dams, carbon and mineral special skills.
And give up the rest
