👉 The "there fluid" refers to the invisible, intangible substance that permeates all matter in the universe, acting as a medium for interactions and processes at the molecular level. This concept, while not a literal bodily fluid like blood or lymph, is often metaphorically described as a universal medium that facilitates communication and exchange between particles, molecules, and even atoms. It plays a crucial role in chemical reactions, biological processes, and the transmission of signals within living organisms, embodying the idea that everything is interconnected through this invisible yet essential substance.
