That's what the various string theory proponents start from. There's "too many" different subatomic particles, so there surely must be something smaller that they're composed of?

How long can you break something apart until you cannot any longer? The things we are breaking apart are illusions in a sense. There will always be a smaller particle because that is what we are looking for.

When we understand that everything that we see is a manifestation of a probability wave, then we will understand everything is a wave and end these foolish experiments.

planck scale is the theoretical limit to disassembly.

If something cannot be reduced, does it exist as an entity?

Do you have a meaningful quantitative explanation with some math we can start building tech on, or will that require some... experiments?

I'll be sure to inform all of the physicists that @Noaidi on Hacker News has solved physics and that they can go home.
