You might want to use a dot for those non-Germans over here.

Is a digital numeric approximation of a real number called "floating comma" in those countries? Or "floating full stop" in the UK?

No, it's called a "floating period", like in the US.

Sci-fi scenario: We find evidence of microbial life from billions of years ago, when Mars was briefly a warm, wet place. Decades hence, a researcher realizes that Mars still has microbial life, but that it has evolved as its environment has, so it's as arid and rarefied as its present atmosphere, wispy and almost not there. Sadly, she realizes that human activity has already doomed it to extinction.

Alternative dystopian scenario: we eventually find evidence of (sometimes extinct) life on all planets and moons that had encountered specific chemical conditions for a long enough period of time. We realize en masse (more than we realize now) that life isn't a unique snowflake, but simply a geological process, not that far removed from rocks and volcanoes. The realization causes a broad spiritual/existential crisis…

Well I've mostly reached that conclusion already. Although more from a hedonistic perspective.

> “micro-digitate silica protrusions”

Or in Thing Explainer-speak, "little rock fingers that stick out."

Its interesting that it was Spirit that detected this- big new discoveries are still coming up after driving the same robot around on the planet for years! Humanity has just barely scratched the surface (as it were) of understanding Mars.

I'm in the US and I've never heard that term before. Google seems equally confused.

The possibility of panspermia means simply finding that life won't, by itself, mean life is inevitable. It will simply mean it happened at least once in the solar system and might spread easily.

Finding microbial life through the solar system won't really make us any less special. Even if we find evidence suggesting microbial life is common throughout the universe, it does not imply that complex animal life is common or inevitable. I suspect the goalposts will just be shifted. :)

"Floating point numbers" are called "Fließkommazahlen" in German, which is a word-for-word translation of "Floating comma numbers".

So at least for German I would say yes.

> spiritual/existential crisis

Only for abrahamic religions. Hinduism/Buddhism and other oriental/ddharmic religions repeatedly downplay our centrality.

It's all selection, I think. Systems tend to seek energy minima (at least locally). Physics, chemistry, biology, information, etc. It's turtles, all the way down. And up, too.
