Aliens Are Floored By Tardigrades

Aliens are floored by tardigrades

Life is pretty resilient. It has to be, especially if the rest of the Galaxy thinks we're from a Deathworld. In comparison then, if their planets are not as demanding, would life there ever be under enough pressure to survive to go to the extreme lengths that some Earth creatures do? I think one of the most profound things aliens might learn from Earth and Humanity is just how powerful life itself can be.

That itself could shake their understanding of themselves - a billion year old civilization could never even conceive of a thing we accept as simple fact, ushering a revolution in thinking not seen in eons.

The Galactic Coalition scientists are busying themselves with obtaining, analyzing, categorizing, and integrating the libraries of information Humanity has brought with them as they incorporate into the greater space faring matrix of civilizations.

A good grasp of Physics, though lacking in certain fields for now; unmatched Engineering doctrines, they really do think of everything, although, perhaps, better to say - they really do attempt everything, then take notes and improve for the next attempt.

Chemistry is another fine addition to the collective knowledge base, a disproportionate part of the catalogue is comprised entirely of explosive reagents and combinations - always good to know more about what NOT to do.

And Biology. Oh boy. What a chaotic but beautiful but also disturbing mess. Life on most planets has a long period of just chugging along, surviving as best it can, until eventually something has the bright idea to evolve the ability to have bright ideas. Then in almost no time at all (on a cosmic scale) a dominant intelligence emerges and civilization alongside it, and in the blink of an eye it finds itself exploring the stars.

A similar pattern happened on Earth, but interrupted alarmingly often by utter catastrophes. Humans call them Mass Extinctions. It is exceedingly rare to find life that can talk about its own extinction events. Kind of deflates the term a bit. Life on planets as inhospitable (by Galactic norms) as Earth tends to be found only as fossils, and almost always on the microscopic level - very rarely do they get the chance to form more complex and advanced lifeforms before the planet with its harsh conditions and scarce resources kills it just as randomly as it spawned it.

We were incredibly saddened to learn from the Humans that the biodiversity of Earth had dwindled by roughly 85% since they accidentally created that giant hole on their planet, and that it had already been on a steady decline before then. Even so, when they revealed there were still 2.4 million species alive on Earth was a shockingly high number. Most are on the brink of extinction, yes, but the fact remains that Earth is easily one of the most biodiverse planets in the Galaxy.

Then we started looking at each individual species and learned about the Tardigrade.

what

It is literally the toughest creature ever discovered, and it's not even close. At least, so far, we haven't looked at absolutely everything Earth has or had yet.

It can just... basically turn itself off and then back on again when the outside becomes livable again - Cryptobiosis, or suspending their metabolism, something we considered only possible through artificial means. And the levels of various extreme they can endure and still be alive would just be utterly ridiculous if they didn't give us samples to confirm for ourselves.

Then we came across the term Extremophile and just decided to take a day off.

Humans are symbiotes

When we met humans we were naïve enough to assume they were like us. We thought each of them was a single entity until our ships systems completed their routine scans.

Of course we offered to rid them of the parasites they carried, it was politeness or so we thought. It took some careful explaining, we expected they would be horrified by the realisation there were microscopic creatures living within them. Instead they were horrified at the thought of losing them.

Humans are each a chorum. Do not be fooled by their use of the singular, the body you see is a vehicle carrying a population of billions.

All the bacteria and viruses we worked so hard to eradicate, humans instead invited in and made a part of them. The relationship is so profound they will deliberately cultivate and ingest the species they prefer to have inside them, and their digestion of food (another horror with their definition of food including a lengthy list of poisons) relies on of having the right population mix.

They create and alter viruses at whim to do many chores, and easily tolerate micro-organisms deadly to us.

They are each a walking army, deadly in the most terrifying way imaginable.

How do I know this?

We thought our systems isolated everything, we thought we were safe and their protective suits were sterilised. Somehow, we missed it. One of the suits had clinging to it a tiny virus colony.

When the Captain realised what was happening they closed every airlock and isolated each section to halt the spread. I got stuck on the lower storage deck for almost two cycles.

The humans did all they could to reassure me from a distance, sharing their knowledge to cleanse the ship for the rescue party. They knew they could not come in, but they would speak to me, make sure I knew what was happening and that they had called for rescue on my behalf, and how long it would be until I could be released.

They were mortified by the actions of one of the feral viruses they consider little more than an irritating pest.

I think they were sad to realise they can never safely interact with us or fully join our union. They can watch from a distance, but never walk on our worlds or share our ships. For a symbiotic ensemble that isolation must be painful even knowing it is vital for life.

I am one of the only members of the union to have met humans in person.

I alone survived the plague the humans later identified as ‘the common cold’.
