- Microscopic: Can matter be infinitely divided? Humanity’s pursuit of the essence of things has led to the discovery of molecules, atoms, electrons, protons, bosons, quarks, quantum particles, and strings. Can they be infinitely small, infinitely divided?
- In terms of the macroscopic scale, there is currently no boundary, while on the microscopic scale, the limit of division is the Planck constant, which represents the smallest unit that can be divided.
- However, these are not the final answers, as tomorrow’s understanding might prove them wrong.
- The only thing humans know is that they don’t know, and the only thing they can measure accurately is the uncertainty.
