Thank you. Once we accept that pure electromagnetic field energy can, in principle, give rise to real particles (e.g. via strong-field QED and related processes), and that subsequent Standard Model interactions can lead step by step to bound states and atoms, I am interested in the conceptual...

Thank you — I appreciate the confirmation. The reason I am asking is to clarify a conceptual point in the discussion: that electromagnetic field energy alone, even in the absence of photons and pre-existing matter, can in principle act as a primary source for matter creation. My interest is...

Thank you for the clarification I fully agree with the points about mass–energy equivalence in special relativity and with the examples you gave (hydrogen binding energy, particle creation in colliders, and annihilation into photons). However, I would like to emphasize the specific scope of my...

Thank you all for the explanations. I would like to clarify an important point in my question: we are explicitly discussing particle creation in the absence of any pre-existing matter. In such a scenario, concepts like kinetic energy of particles are not applicable, because kinetic energy...

Thanks. If the energy stored inside an atom can ultimately appear as electromagnetic (EM) radiation when the atom is broken, does this imply that EM energy is required to form or “set” an atom in the first place?

What type of energy is actually stored inside an atom? When an atom is split—such as in a nuclear explosion—it releases enormous energy, much of it in the form of gamma-ray electromagnetic radiation. Given this, is it correct to say that the energy stored in the atom is fundamentally...

Thanks for your comprehensive reply. Please be aware that I didn't ask what is the volume, I have asked if BH has a volume. If the Black hole is not well defined, then we have to agree that it could have a volume. If we claim that a black hole has no volume, then by definition we defined the...

If it has spacetime, then how could it be that it has no space or volume? Can you please explain the contradiction? Please be aware that the number of atoms in the sun comes to 1.201×10^57. Therefore, in a neutron star with one solar mass there should be at least 10^57 neutrons while a BH with...

Wow! Thanks As you confirm that BH is not a singularity or a point and It does have spacetime inside it, then do you agree that BH must have some minimal space/volume/radius?

Thanks Do appreciate your reply. As the matter can't occupy the same quantum state/same space without breaking the law of science, then why do we insist for a singularity in a BH? Why can't we agree that even BH should have some sort of internal space/radius? What about SMBH and quasars? Do...

This textbook was published in 1983. https://onlinelibrary.wiley.com/doi/book/10.1002/9783527617661 Black Holes, White Dwarfs, and Neutron Stars: The Physics of Compact Objects Author(s): Stuart L. Shapiro, Saul A. Teukolsky First published:27 July 1983 Stuart Louis Shapiro is an American...

I assume that Shapiro & Teukolsky have offered the idea for the formation of the Neutron stars. However, any idea should be confirmed by some sort of evidence. Yes, we have evidence: In the following article it is stated: Evidence for quark-matter cores in massive neutron stars...

Thanks for your prompt reply!

Would you kindly answer the following questions: 1. Do you confirm that in stars there must be more protons than Neutrons? 2. As there are much more protons than neutrons in a star, then why after the supernova we get a star which is mainly based on Neutrons and therefore it is called Neutron...

A quark star may have just been discovered https://www.advancedsciencenews.com/a-quark-star-may-have-just-been-discovered/ a recent discovery may point toward the existence of a new type of star: the quark star. The hypothesized existence of such objects was first expressed in 1965 by Soviet...
