Default This is the most dangerous time for our planet - Stephen Hawking

An interesting article where Stephen Hawking comments on the current state of the world : https://www.theguardian.com/commenti...net-inequality

I hope this topic will not degrade into a heated debate, else I will have to close the thread

Well, someone needs to respond to this! We should have a poll for it (that's a less controversial way to do it) and the question would be: "Will humanity exterminate itself within the next 50 years, or not?"

My vote: it's an absolute certainty.

I was not that excited about Hawkings "A brief history of time" - I'm a fan of popular physics, but more on the order of Heinz R. Pagel's "symmetry" and Joao Magueijo's "Faster than light" - but I tended to agree with much of the article.

He's really just reiterating the concern of Enrico Fermi in the thought vein of Enrico's "The Great Filter" - which is that at some point, technology becomes both too powerful to be used responsibly, and too easy to obtain and to replicate, and thus it destroys the civilization that created it (with the help of members of the unlucky life form (which in our case, woud be humans)). The answer to the Fermi Paradox explains why we've never been contacted by alien life forms, in spite of (Fermi's) calculations that would otherwise make such a contact reasonably certain.

Synopsis: Lifeforms always extinguish themselves when a certain threshold is reached wherein the technology starts to increase at a very steep (exponential) rate. It is around this time that far-travel by that civilization would be possible, or at least communications would be, but the window of time, within which the civilization exists, is too short, and such a civilization vanishes before its window is coincident with another's.

So, Fermi, here's a +1 for ya!

An interesting theory, but too simplistic and based on assumptions.

Can you give one concrete example of a lifeform that has done this?

No, but I can't supply a single example of the alien contact that would prove Fermi's theory wrong, either.

If you read him, and his theories and his rationale speaking for the existence of (probably) many "come and gone" civilizations (over the billions of years) - it's plausible. Obviously all theory. Bright guy though.

I saw this documentary once: 12 Monkeys. Very interesting.

I know some actually counting on this

In Egypt we have a proverb that goes like this "Yala Beena | Let's go", you say with a sarcastic sound
