>>11672394It most definitely isn't nano tech and we would discuss that later.
The Thing is a biological creature and biological impossibility
First and foremost: it has no definite nervous system yet, it can take complex structures and dissolve it at anytime in a matter of seconds. That's a complete bullshit because metamorphosis take weeks in order to properly liquefy and restructure the insect. And even then, it still retain its memories from before - thus suggesting that it was never a complete liquefaction. Even at the moment it hatches as a larvae, its future is already hardcoded in its DNA. Slugs, Jellyfish, Hydra, even bacteria all have definite shapes dictated by their DNA.
The Thing has no definte DNA that mutates without warning without turning cancerous.
Secondly: there exists nothing that can safely process, distribute, and consume energy as fast as how The Thing creates entire new ligaments that was recently cut and destroyed. The most powerful stomach acid in the world belong to vultures and even they cannot digest bones.
There exist acids that can make stomach acid pale but those acid are not designed for biological creatures
I remember a case of a scientist who made an oopsie, causing a drop of super acid to fall into his thigh. He immediately flee to the pool, hospitalized, got amputated, but still died because the acid can literally break down every single chemical compound in such a way that not even the nervous system could take note of the chemical reactions.
The Thing is most definitely NOT nanobot tech because nanobots are antonymous - they move as an individual. They may form colonies in order to create complex compounds more easily with the assistance of each other but as a whole, only 1 nanobot is needed to survive to keep the colony alive. They can travel insectborne, waterborne, or airborne. Exactly like a virus except it is not alive and can break you down to your simplest compounds just so they could self-replicate.
Grey Goo wins.
