Did you actually make an argument yourself somewhere in there?
Although, I have made my point clear but unfortunately because of my little carelessness you dudes had a chance to mess things up. Anyway, that would not stop me from writing the truth which some people are twisting on purpose to support their pleasure seeking behaviour.
In my following argument I will totally avoid any technical term such as abstract mathematical ideas like real/complex vector spaces, bra-ket, conjugates, Hermitian operators, Hamiltonian, Eigen etc. so the folks who do not have any idea of what quantum physics is can also follow this discussion.
Let us assume that we have two metal balls which are detectable because of their physical properties. If force applied on these balls they can move and interact. This is our first observation.
In case we move the metal balls closer and they start influencing each other without even interacting physically that gives us an understanding that these balls also have some indiscernible properties. When these balls start attracting or repelling each other this behaviour leads us to our knowledge of magnetism. This is our second observation which is indirect in nature.
Conclusion: Metal balls are directly detectable due to their physical properties. However, magnetic fields are detectable only when those fields start influencing other objects.
In today’s world it is a common knowledge that atoms are not the fundamental particles and they are also made of even smaller particles.
Atoms are made of nanoscopic balls called Fermions and the force those fermions carry are known as Bosons. When force fields (bosons) interact they can influence fermions to behave in certain ways. Fermions are detectable due their physical properties and bosons are detectable indirectly by the way fermions behave during their interactions.
By the word particle the first idea which may occur in mind is about something that is solid and that has detectable physical properties such as colour, shape, mass, etc. The force field on the other hand is not detectable until it interacts with something. However, scientists decided to put both fermions and bosons (force fields) under the same category of particles in quantum physics. Both fermions and bosons are called particles and that is the point when things start getting fuzzy for a person who is not well educated in science.
When two electrons approach each other, their charges create a disturbance. This disturbance pushes them apart and their paths bent outwards. In case of electron and positron the disturbance is similar in type but different in details so oppositely charged electron and positron attract each other and their paths are bent inwards. In other words, when two fermions interact their force fields mediates a force that changes their momentum and path of motion.
Many scientists push the idea that when two force fields interact together there is an exchange of undetectable particles (the Virtual Particles or Photons) that cause the attraction or repulsion among interacting fermions which carry those force fields. As if force fields are made of invisible particles which push or attract each other when they come near to each other. But this is just a Jargon because force fields are not detectable directly and nobody knows what exactly is happening inside those interacting fields. Scientists call those interactions of force fields “Exchange of Virtual Particles.” They call these particles “Virtual” because:
They are not detectable directly
They would never be found on their own
They do not have energy to become a well formed ripple moving through space and
They decay as soon as their causes are gone.
This is what a “Virtual Particle” and some people are twisting this idea to spread a false concept that at quantum level “Virtual Particles (as if REAL PARTICLES)” can appear out of nowhere.
This concept is wrong for one more reason. In modern physics there is no such thing as empty space. Fields pervade space. They are conditions and properties of space. The vacuum is filled with electromagnetic fields which are active and dynamic and within these fields always some activities are happening at nanoscopic levels. These fields are not smooth and fluctuations may cause energy-mass-energy conversions at small levels. In no way one can claim that energy-mass-energy conversions happen out of nothing because an unfathomable ocean of fluctuating fields provide a good solid base for such activities.
Saying that “Virtual Particles” can come into existence from nothing is a deliberate abuse of science. To me it seems that people who resist the idea of God are putting another effort to spin layman’s head with a false concept. Just like they did it by spreading the idea of Natural Selection without giving intelligible mechanism for Natural Selection.
