The question of where the smallest particles, such as subatomic particles, get their existence from is a complex and philosophical one. In the realm of particle physics, particles are considered fundamental entities, meaning they are not composed of anything smaller. They are considered the building blocks of matter in our current understanding of physics.
According to the prevailing theory in particle physics called the Standard Model, elementary particles such as quarks, leptons, and gauge bosons are considered fundamental. They do not possess internal structure and are not composed of smaller entities. Instead, they are considered to be the fundamental constituents of matter and energy.
In terms of their existence, these particles are understood within the framework of quantum field theory. Quantum field theory describes particles as excitations or quantized vibrations of underlying fields that permeate space. These fields are thought to exist throughout the universe and interact with particles, giving rise to their properties and behaviors.
However, when it comes to the ultimate origins of these fundamental particles and the fundamental fields themselves, science currently does not have a complete answer. The question of where the fundamental particles get their existence from delves into deep philosophical and metaphysical inquiries that extend beyond the scope of scientific understanding.
In various scientific and philosophical perspectives, explanations may differ. Some theories propose that the existence of fundamental particles and fields arises from a deeper, underlying structure or principle yet to be discovered. Others speculate on the possibility of multiple universes or dimensions that could give rise to different particle properties and interactions.
Ultimately, the question of the origin of the smallest particles remains an area of active exploration and speculation within the realms of physics, cosmology, and philosophy. It represents one of the profound mysteries that continue to drive scientific inquiry and our quest to understand the nature of the universe.
