Being about 20 nanometers tall, the world around you looks more larger. From the eyes that I have, everything is about the size of mountains. Transistors have transitioned from flat two-dimensional shapes into three-dimensional structures commonly known as FinFETs (Fin Field-Effect Transistors), which resemble tiny fins or needles standing vertically on the silicon wafer.
At this point, a single atoms is the size of a marble. Which would be about (9 mm or .35 inches), that is equivalent to a 6 foot adult. Your ”giant” world is looking different by now. From where you are standing, a single bacteria is now a 164-foot tall skyscraper. To us universes might as big as a galaxy, or even bigger.
