    that's because there are like I said, not real and merely part of mathematical modeling, and yes, that's what the EXPERTS say.universeness

    Exactly what I meant. Parroting the experts. It's exactly the point of disagreement though. There are so-called experts who say virtual particles are real, and the mathematical expressions a mere woowoo fantasy, which is unjustified given real existence It is stated that a particle is an excitation. But then a fluctuation is just as real. Only the fluctuations are not directly observed. Only indirectly.

    So, it's parroting, and your comparison to Trump is made to elevate yourself to a height you don't have. Like I said, there are physicists who consider the virtuals real. The math has to describe something. Particles! Not on mass-shell.

    It's not a matter of majority votes if they are real or not...

    There are so-called experts who say virtual particles are realHillary
    I accept that many 'experts' assign a form of 'existence' to virtual particles but I dont think many of them would use the term REAL for VIRTUAL particles as used in perturbation theory.
    From wiki:

    A virtual particle is a transient quantum fluctuation that exhibits some of the characteristics of an ordinary particle, while having its existence limited by the uncertainty principle. The concept of virtual particles arises in the perturbation theory of quantum field theory where interactions between ordinary particles are described in terms of exchanges of virtual particles. A process involving virtual particles can be described by a schematic representation known as a Feynman diagram, in which virtual particles are represented by internal lines.

    Virtual particles do not necessarily carry the same mass as the corresponding real particle, although they always conserve energy and momentum. The closer its characteristics come to those of ordinary particles, the longer the virtual particle exists. They are important in the physics of many processes, including particle scattering and Casimir forces. In quantum field theory, forces such as the electromagnetic repulsion or attraction between two charges can be thought of as due to the exchange of virtual photons between the charges. Virtual photons are the exchange particle for the electromagnetic interaction.

    The term is somewhat loose and vaguely defined, in that it refers to the view that the world is made up of "real particles". It is not. "Real particles" are better understood to be excitations of the underlying quantum fields. Virtual particles are also excitations of the underlying fields, but are "temporary" in the sense that they appear in calculations of interactions, but never as asymptotic states or indices to the scattering matrix. The accuracy and use of virtual particles in calculations is firmly established, but as they cannot be detected in experiments, deciding how to precisely describe them is a topic of debate.] Although widely used, they are by no means a necessary feature of QFT, but rather are mathematical conveniences - as demonstrated by lattice field theory, which avoids using the concept altogether

    Yes, loops are used in perturbation theory. The vacuum contains no real particles but virtual particles are there! The quantum bubbles. Closed isolated loops, which interact with other virtuals (higher order Feynman diagrams). What do you mean if you say the fluctuation is real? Isn't that even weirder? Virtual, in this context and in my humble opinion, just means not on mass-shell. You know what on mass-shell means? It's pretty unreal!

    the quantum vacuum is filled with fluctuations?Hillary

    I know, we have descriptions such as:
    In quantum physics, a quantum fluctuation (also known as a vacuum state fluctuation or vacuum fluctuation) is the temporary random change in the amount of energy in a point in space, as prescribed by Werner Heisenberg's uncertainty principle. They are minute random fluctuations in the values of the fields which represent elementary particles, such as electric and magnetic fields which represent the electromagnetic force carried by photons, W and Z fields which carry the weak force, and gluon fields which carry the strong force. Vacuum fluctuations appear as virtual particles, which are always created in particle-antiparticle pairs. Since they are created spontaneously without a source of energy, vacuum fluctuations and virtual particles are said to violate the conservation of energy. This is theoretically allowable because the particles annihilate each other within a time limit determined by the uncertainty principle so they are not directly observable

    But this is a MODEL of what is going on within the 'broiling' vacuum of space.
    It's certainly true, that it is completely wrong, to try to suggest there is a point of spacial existence where absolutely nothing is happening, no activity at all.

    Science currently has very very very little knowledge of what is actually going on in the vacuum of space. Particles probably don't exist in the traditional point particle or small free, disconnected spherical forms we have envisaged in the past. They probably are field excitations and 'Virtual particles' are just some form of field excitation we really don't understand. Just like we don't understand phenomena such as quantum tunneling.
    Our understanding of quantum physics is still at an infantile stage.
    Your claim that you have solved the greatest mystery we have is just that, an individual's claim.
    One can believe in it if one chooses to ignore experts who dissent against it.

    No, at this point, I don't know what on mass-shell means but from wiki:

    In physics, particularly in quantum field theory, configurations of a physical system that satisfy classical equations of motion are called "on the mass shell" or simply more often on shell; while those that do not are called "off the mass shell", or off shell.

    I am aware of the classical equations of motion such as speed=distance/time etc

    In quantum field theory, virtual particles are termed off shell because they do not satisfy the energy–momentum relation; real exchange particles do satisfy this relation and are termed on shell (mass shell).
    In classical mechanics for instance, in the action formulation, extremal solutions to the variational principle are on shell and the Euler–Lagrange equations give the on-shell equations. Noether's theorem regarding differentiable symmetries of physical action and conservation laws is another on-shell theorem


    I am not familiar with 'the action formulation,' 'the variational principle,' 'the Euler-Lagrange equations,' 'Noether's theorem' etc but I have often suggested that you look to qualified physicists to debate your more detailed academic physics musings with.
    I don't accept your physics viewpoints because many physicists disagree with you as has been demonstrated on quora.

    But J do know. Particles are no points, but tiny higher dimensional spheres, filled with charge or transporting energy and momentum, like photons. Or carrying metric of spacetime metric. Or carrying energy and momentum and color or electric charge. Or supercolor charge There are 7 basic charges and all couple to the virtual fields, the quantum vacuum, ti interact. Space is made of virtual particles, in a sense. Real particles couple to it to interact. Coupling to the virtual graviton field causes spacetime to curve (graviton condensate).

    There are levels of laypeople. I am not a physicist. I got an A at higher grade but failed the physics exam at the end of my 1st year Uni course. I also failed the resit and had to carry a different Ist year uni subject into 2nd year but I aced that so well, that I got an exemption from the final exam at the end of 2nd year. I have progressed my physics since then based on my own studies and some online courses I have completed on edx.org since retiring.

    From quora:
    It happens as follows :

    Photons from the Sun strike your skin .
    In this process, they may collide with the electron .
    The electron gains energy from the photon and gets promoted to a higher energy state .
    The electron then stabilizes itself by releasing energy .
    This energy is nothing but the warmth or heat energy that the sun makes us feel .
