Synthesis of Life forms Synthesis of Life forms Hey! I had watched an instagram reel of a guy making a self-sustaining terrarium earlier and it had me wondering if it was possible to make a larger model like that but meant to observe if new life forms could be created. By that, I mean is it possible to make a “terrarium” somehow modeling the same conditions as there were billions of years ago; like with mini oceans, bacteria, other microorganisms essential to life, and an atmosphere… Read more
