[Rockhounds] A field guide to finding fossils on Mars. (open access paper)

Sound thinking , Kitty 😉
In my personal opinion, de Drake equation is nonsense. There are probably far more planets than we can imagine but fewer of those are perhaps capable of producing life.
Those people who are now staggering and shouting that life isn't necessarily carbon-based and that silicon is as good a candidate as carbon can lean back and continue watching their favorite shows on the (self-proclamed) Science Channel... Ancient Aliens, Alien encounters, and such... The longest stable chain that one can form with silicon is 8 atoms long. Not nearly enough for life... The hybridization of carbon is what makes life, nothing else.
Professor Michio Kaku should stop filling our heads with BS. There are no 4 stages of civilization... as he cites Nikolai Kardashev. That must have been the vodka speaking...
A Type I civilization—also called a planetary civilization—can use and store all of the energy available on its planet.
A Type II civilization—also called a stellar civilization—can harness the total energy of its planet's parent star (the most popular hypothetical concept being the Dyson sphere—a device which would encompass the entire star and transfer its energy to the planet(s)).
A Type III civilization—also called a galactic civilization—can control energy on the scale of its entire host galaxy.
What an idiotic idea!

Then why haven't we heard from another intelligent species yet???
Because of the Emmermann Threshold. I named it after myself, because nobody else would 😉
It works like this:
1) evolutions favors the strongest
2) the strongest take care of their own needs first
3) the strongest and most egoistic individuals gather the most resources and get to hold power and multiply
4) civilization becomes materialistic beyond reason
5) Civilization destroys planet and itself before it can make contact with other planet-dwellers.

We're there already, we know it and we're still pumping up oil....

Dora,

"NO!"? As in "NO! You haven't read the paper."? Or that you REFUSE to read the paper?

I'm going out on a limb here and guessing you think that "Planet Earth" is the only place with life (past or present). While conditions today may not be favorable for life, who's to say they werent in the past. The article simply indicates what scientists should look for in the way of life that may have evolved when conditions were still favorable. I don't think there were ever "Little Green Men" on Mars. Maybe elsewhere in the universe though. I'd love to know what kinds of minerals they're collecting. 🙂

But I do think there has to be life of some kinds out there. Otherwise, there's a whole lot of wasted if our planet is the only occupied one.

Going back under my rock now. lol

NO.

Spoken from Planet Earth.   Without any of that funny weed.
