В отзыве журнала "Письма ЖЭТФ" на апелляцию рецензент не возражает против спина плоской волны, но отрицает новизну представленого результата. Однако он не приводит никаких ссылок на то, что передача спина плоской волны зеркалу известна:

"Да, различают орбитальный угловой момент и спиновый угловой момент. Известно, что циркулярно-поляризованный свет обладает спиновым моментом. В общем случае угловой момент есть сумма углового и спинового, при отражении они изменяются одинаково. Например, при нормальном отражении и тот, и другой не меняют знаки. При наклонном падении зеркалу передается момент, параллельный зеркалу. Считаю, что новизны, а тем более открытия нового явления в статье нет".

Речь идет о статье "Спин, передаваемый зеркалу при отражении света" http://khrapkori.wmsite.ru/ftpgetfile.php?id=156&module=files , где

"Рассмотрено падение на зеркало под углом и отражение от зеркала плоской электромагнитной волны круговой поляризации. Рассчитана передача спина волны зеркалу и, соответственно, плотность механического вращающего момента силы, воздействующего на зеркало"."

Abstract— It is shown that the energy-momentum pseudotensors of the gravitation field, which were proposed by Einstein or Landau and Lifshitz, give a positive contribution to the expression of the total mass-energy for a gravitation field plus the matter located in it in the case of a quasi-static isolated system. However, as is well known, mass-energy of the gravitation field is negative. So, the pseudotensors incorrectly represent the gravitational field at least in this case.

We are happy to inform you that your paper entitled "The Pseudotensors do not Represent Gravitational Energy " [http://khrapkori.wmsite.ru/ftpgetfile.php?id=168&module=files] has been accepted for "ICGRG 2018: International Conference on General Relativity and Gravitation" to be held on Jan 29-30, 2018 in Sydney, Australia.

However, comments were received on 2017-11-30

Abstract— [E1] It is shown that the energy-momentum pseudotensors of the gravitation field, which were proposed by Einstein or Landau and Lifshitz, give a positive contribution to the expression of the total mass-energy for a gravitation field plus the matter located in it in the case of a quasi-static isolated system. However, as is well known, mass-energy of the gravitation field is negative. So, the pseudotensors incorrectly represent the gravitational field at least in this case.

[E1] Please follow the guidelines below to what your abstract should include:

- an introductory statement that outlines the background and significance of the study

- a succinct description of the basic methodologies

- a clear indication of the major findings of the study

- a concluding statement

I rewrote the Abstract on 2017-11-30, and I sent version 2

Version 2 comments were received on 2017-12-02

Abstract— Einstein and others proposed to describe the mass-energy of the gravitational field by a pseudotensor in order to extend the conservation law to the gravitational interaction in the frame of the General Relativity.[E2] We calculated the contribution of the pseudotensor to the total mass of a stationary material body and its gravitational field. It turned out that this contribution is positive. However, as is known, the mass-energy of a stationary gravitational field is negative. We concluded that the pseudotensor incorrectly describes the energy of the gravitational field.

[E2] Please do not refer to other studies and do not give any information that requires citations. As the abstract should be self-contained, you are kindly requested to remove such information from your abstract.

I rewrote the Abstract on 2017-12-02 again, and I sent version 3

Abstract— As is well known, the energy-momentum pseudotensor of the gravitational field is used in order to extend the conservation law to the gravitational interaction in the frame of the General Relativity. We calculated the contribution of the pseudotensor to the total mass of a stationary material body and its gravitational field. It turned out that this contribution is positive. However, as is known, the mass-energy of a stationary gravitational field is negative. We concluded that the pseudotensor incorrectly describes the energy of the gravitational field.

Version 3 was ignored, and a repetition of version 2 comments was received on 2017-12-04

I rewrote the Abstract on 2017-12-04 again, and I sent version 4. I added:

“The abstract should include  an introductory statement that outlines the background of the study.

Accordingly, our statement “As is well known, the role of the energy-momentum pseudotensor of the gravitational field is to extend the conservation law to the gravitational interaction” outlines the background of the study. This statement does not require citation”.

Two comments of version 4 were received on 2017-12-11

Abstract [N4]— As is well known, the role of the energy-momentum pseudotensor of the gravitational field is to extend the conservation law to the gravitational interaction in the frame of the General Relativity [N5] . We calculated the contribution of the pseudotensor to the total mass of a stationary material body and its gravitational field. It turned out that this contribution is positive. However, as is known, the mass-energy of a stationary gravitational field is negative. We concluded that the pseudotensor incorrectly describes the energy of the gravitational field.

[N4] The quidelines below list what an abstract should include:

-an introductory statement that outlines the background and significance of the study,

-a succinct description of the basic methodologies,

-a clear indication of the major findings of the study,

-a concluding statement

[N5] Abstract should not contain any information that requires citation, statistical information, quotation, and sentences that refer to other studies.

1. Рецензент пишет: "гравитационный дефект массы отрицателен", хотя звезда нагревается при гравитационном сжатии, масса-энергия её вещества М растет, дефект массы звезды положителен. Соответственно, энергия гравитационного взаимодействия – отрицательна, как известно из школы.


2. Эта растущая масса звезды М равна интегралу от плотности по пространственному объему. А рецензент пишет, что М - это масса материла звезды, если его разнести на бесконечность.


3. Это шварцшильдовский параметр m есть масса, создающая поле на бесконечности. Поэтом именно m является массой разреженной звезды, а не М.


4. Неравенство  M > m как раз означает положительный дефект массы в соответствии с § 100 "Теории поля", а рецензент пишет: "гравитационный дефект массы отрицателен".


5. Упоминание рецензентом гравитационных волн подтверждает его неадекватность. Статья никак не касается волн.


6. Именно интеграл Толмена от псевдотензора рассматривается в статье, как того хочет рецензент. И этот интеграл, равный гравитационной энергии по идее Эйнштейна, оказывается положительным, хотя энергия гравитационного взаимодействия – отрицательна, что известно из школы.
