We are speaking of the universe.

I follow Patrice Ayme and have done for many years. Some of his posts are super-intellectual and those I struggle to understand.

But a post published on September 8th, 2024 was very easy for me, and countless others no doubt, to understand and I have pleasure in republishing it on Learning from Dogs today.

No Civilizations Out There, We Are It. We Must Rise To The Occasion

September 8, 2024

I doubt that there are civilizations around. We are facing a galaxy devoid of intelligent aliens: little green mats out there, not little green men.

First, we don’t see them. With foreseeable technology (hibernation, nuclear propulsion, compact thermonuclear reactors, bioengineering, AI, quantum computers) we should be able to send very large interstellar spaceships at 1,000 kilometers per second… Thus it would take a millennium to colonize the Centaur tri-star system…. 25,000 years to colonize a 200 light years across ball… And the entire galaxy in ten million years… Wars would only accelerate the expansion. So if there was a galactic civilization, within ten million years it would have spanned the entire galaxy and its presence should be in sight.

Second, life took nearly four billion years to evolve animals. Bacterial life could have been nearly extinguished on Earth many times…. Be it only during the Snowball Earths episodes. A star whizzing by could have launched a thousand large comets. The large planets could have fallen inward.

Third, ultra intelligent life may not be able to have hands or tentacles and thus develop industry. Once intelligent life forms have evolved, say sea lions or parrots, let alone wolves, they may just be sitting ducks for the next disaster which would revert life to the bacterial level, erasing billions of years of evolution.

Fourth, when civilization is launched, it can fail… And not get a second chance (from lack of availability of mines after easy picking during the initial civilization).

Fifth, nuclear powered Earth is special. Earth has plate tectonics, probably from a nuclear reactor at the core, keeps the CO2 just so for a temperate temperature… Water, but not too much. Her large Moon stabilizes her. Earth doesn’t have a weird rotation like Venus (retrograde and slow) or Mars (spectacularly tilting axis). Ian Miller has aluminosilicates considerations on top of that.

So I don’t expect little green men… Besides those sent by the perverse Putin…

Just when we thought we knew of all the stress, here is another one: if we go extinct, the universe loses its soul! We have thus found a new Superior Moral Directive: SUS, Save Unique Soul!

Expect little green mats, not little green men.

A couple of weeks ago I gave a talk to our local Freethinkers group and called it The Next Ten Years. It began, thus:

This presentation is about the world of the future; of the near future. And the biggest issue, most agree, is the change in the climate. 

The Global Temperature anomaly, as of last year, 2023, is 1.17 Centigrade, 2.11 Fahrenheit, above the long-term average from 1951 to 1980. The 10 most recent years are the warmest years on record.

Antoine de Saint-Exupéry is quoted as saying that ‘a goal without a plan is just a wish.’ So my plan is to show you how we can change, no let me put that more strongly, how we must change in the next ten years. Because our present habits are ruining the world.
