New “Astrobiological Copernican Limit” claims 36 intelligent civilizations

It’s all malarkey. In the real world, it would be awfully nice to find fossil bacteria on Mars. When that seems to be taking some time, we hear about 36 alien civs. That’s because there’ll always be a market for We Are Not Alone. The thing is, it used to be called religion, not science. And it still IS religion, not science.

Researchers: Organic chemicals essential for life found in Martian meteorite; Rob Sheldon responds

Sheldon: The point is that we don’t expect to find nitrate and ammonia in the soil of Mars, not unless some nitrogen fixing bacteria put it there recently, because over time it will all come out of the soil as N2 gas. Claiming that the process goes the other way, from N2 in atmosphere to nitrates in soils, goes backwards, from high entropy to low entropy.

Researchers: Organic chemicals essential for life found in Martian meteorite; Tim Standish responds

Standish: If the nitrogen cycle isn’t established within a certain time, nitrogen will be removed from the atmosphere and the surface will become rich in nitrate (bad) or, in a reducing atmosphere, ammonia (really bad). The bottom line is that there are speculations that probably get around this, but it is one more needle that has to be threaded for chemical evolution to produce the first life, or a problem for the first life to quickly take care of.

Our idea of life is “too Earth-centric!”

Koontz at Massive Science, on NASA’s Darwin-only definition of life: “For instance, say we find a planet full of aliens who have achieved immortality. The population has been stable for thousands of years, with nobody being born and nobody dying — in other words, there is no self-replication going on. There is no variation. Everything is static. There’s no evolution. Would this alien species be considered living under our current definition?”

Big new telescope array to search for extraterrestrial alien signals

The nice thing about SETI (Search for Extraterrestrial Intelligence) projects is that it makes very little difference if we don’t find anything. It’s not as though any conclusion can be drawn from a failure to find anything. We will just indulge in another round of speculations as to why we don’t. It’s not always clear why this is a science and not a religion. But hey.

SETI @ Home shuts down

Well, the state of computing has certainly changed but, after so many years of no Contact, the magic has probably also gone out of the Search for Extraterrestrial Intelligence (SETI) project. Also, to use the “Woke” approach that is becoming increasingly popular in popular science, why should SETI get to say what is and isn’t a valid search for ET? Why should SETI control the narrative? Can’t everyone have or be their own ET? Sow the wind…
