correct me if I am wrong but there are fundamental fields that are responsible for the forces and properties. A) how do these fields (em, higgs ect.) influence matter? B) where did they come from and when? Thanks
how do these fields (em, higgs ect.) influence matter?
We observe “ticks in detectors” not [necessarily] as 'particles', not as 'fields'. Such ticks are caused by some property of the object observed, such as charge, momentum or position. Are these a property of a field or of a particle? The ticks do not answer these question; An answer depends on the physical theory you are using to interpret the ticks.
Carlo Rovelli: “…we observe that if the mathematical definition of a particle appears somewhat problematic, its operational definition is clear: particles are the objects revealed by detectors, tracks in bubble chambers, or discharges of a photomultiplier…”
A particle is in some sense the smallest volume/unit in which the field or action of interest can operate….Most discussions regarding particles are contaminated with classical ideas of particles and how to rescue these ideas on the quantum level. Unfortunately this is hopeless.
B). A particle detector measures a local observable field quantity (for instance the energy of the field, or of a field component, in some region). This observable quantity is represented by an operator that in general has discrete spectrum. The particles observed by the detector are the quanta of this local operator.
Everything around us came from the big bang or it's remnants.where did they come from and when?
. In the quantum field theory view, "real particles" are viewed as being detectable excitations of underlying quantum fields. As such, virtual particles are also excitations of the underlying fields, but are detectable only as forces but not particles. They are "temporary" in the sense that they appear in calculations, but are not detected as single particles.
Fundamental fields are physical quantities that describe the fundamental interactions between particles. These interactions are responsible for the forces and behaviors observed in the universe.
There are four known fundamental fields: the gravitational field, the electromagnetic field, the strong nuclear field, and the weak nuclear field. These fields are described by different mathematical equations and govern different interactions.
The origin of fundamental fields is still a topic of ongoing research and debate. Some theories propose that they emerged from the Big Bang, while others suggest they may be related to the structure of space-time or symmetries in the universe.
Fundamental fields interact with matter through the exchange of particles. For example, the electromagnetic field interacts with charged particles through the exchange of photons, while the strong nuclear field interacts with quarks through the exchange of gluons.
While there is currently no evidence for additional fundamental fields, it is always possible that new fields may be discovered through further experimentation and research. The study of fundamental fields is an active area of study in physics.
