Is there still a physical, indivisible substance at the base of materiality?

Question

According to the classical model of materiality, all matter is made up from an indivisible substance. Therefore our definition of materiality is based on this idea that at root matter is substance, something physical with three dimensions. If this is no longer true, does it mean there is no matter, as understood in the classical sense? I’m no scientist; therefore I would appreciate a simple explanation as to the nature or properties of matter as understood today, related to the classical understanding of matter.

Answer 1

Not exactly. The idea of little indivisible particles knocking around waiting to get built into stuff is classical thinking. The world is not classical, though. Current thinking in quantum mechanics is that there a certain "ground state" to the universe, colloquially referred to as the vacuum (which is not "nothing"), in which energetic perturbations are manifest as the various particles. So, "the base of materiality" is more analogous to a blank sheet of clay waiting to be drawn upon, ias opposed to a box of legos waiting to be assembled into something.

Answer 2

Current line of thinking is that all particles are made of very small strings that vibrate at different frequencies. The frequency of vibration determines what the particle is. So, in essence, we are still talking about a single indivisible particle, it is just further down the ladder than classical physics originally thought.

Answer 3

well at elementary level we are taugh classical theory of matter, then there is the quantum theory
but mostly everything is still under research

and some weirdo scientists are talking about 11 dimensions so well, well its difficult to say anything here, you need to join some research project or something to know the right things
