Art Hobson said that quanta propagate in space to infinity. (sorry can not give a link)

Quantum Field Theory (QFT) is a theoretical framework that combines quantum mechanics and special relativity to describe the behavior of subatomic particles. It is the most accurate and comprehensive theory we have for understanding the fundamental building blocks of the universe.
In Quantum Field Theory, particles are not considered to have a definite size. Instead, they are described as excitations of a quantum field. The size of an electron is not a physical property that can be measured, but rather a manifestation of its interactions with other particles and fields.
No, Quantum Field Theory does not predict an infinite size for the electron. In fact, according to the theory, the electron is a point-like particle with no internal structure or size.
Renormalization is a mathematical technique used in Quantum Field Theory to deal with infinities that arise in calculations. It involves redefining certain parameters in the theory to eliminate these infinities and make the results of calculations finite and physically meaningful.
In Quantum Field Theory, the mass of the electron is not an intrinsic property of the particle, but rather a result of its interactions with the Higgs field. The Higgs field gives particles their mass by interacting with them, and the strength of this interaction determines the mass of the particle. Without this interaction, the electron would be massless.
