Gravitomagnetic effects

We provide an analysis and statement of the source term in the classical Kaluza field equations, by considering the 5-dimensional 5D energy-momentum tensor corresponding to the 5D geodesic hypothesis that is typically presumed in the Kaluza theory. By providing the 5D matter Lagrangian, this work completes a Lagrangian analysis of the classical Kaluza theory that began by establishing the proper form of the unique Kaluza field Lagrangian. This work considers the transformation properties necessitated by general covariance of the Kaluza source terms, to establish the correct form for the source terms in the field equations, and to establish the 5D matter Lagrangian that corresponds to the 5D geodesic hypothesis. In addition to the effects of a scalar field expected from other scalar-tensor or scalar-electromagnetic theories, a peculiar Kaluza coupling coefficient arises for charged matter which acts to vary the source strengths in ways unknown to conventional physics. We briefly evaluate the implied modifications to source terms in the field equations. We find an ADM-like neutralization of gravity at high specific charge states and a saturation in field strength at high specific charge-to-mass ratios.

No experiment to date has provided evidence for quantum features of the gravitational interaction. Recently proposed tests suggest looking for the generation of quantum entanglement between massive objects as a possible route towards the observation of such features.

Matos Published Abstract: Using the weak field approximation, we can express the theory of general relativity in a Maxwell-type structure comparable to electromagnetism. We find that every electromagnetic field is coupled to a gravitoelectric and gravitomagnetic field. Acknowledging the fact that both fields originate from the same source, the particle, we can express the magnetic and electric field through their gravitational respective analogues using the proportionality coefficient k.

This article is meant as a summary and introduction to the ideas of effective field theory as applied to gravitational systems, ideas which provide the theoretical foundations for the modern use of general relativity as a theory from which precise predictions are possible. Quantum mechanics and general relativity were discovered within a decade of one another close to a century ago, and almost immediately the search for a quantum theory of gravity had begun. Ever since it has been a puzzle as to what theoretical framework might ultimately reconcile these two theories with one another. This reconciliation has proven to be difficult to achieve, and although several promising proposals now exist none can yet claim complete theoretical and experimental vindication. The long-standing nature of this difficulty has driven some physicists to a state of intellectual despair, wherein they conclude that a crisis exists in physics which might be called the crisis of the split brain.

Observable quantum entanglement due to gravity

 Багаж, сеньор. Я могу вам помочь. - Спасибо, не. Мне нужен консьерж. На лице привратника появилась обиженная гримаса, словно Беккер чем-то его оскорбил.

ГЛАВА 45 Дэвид Беккер бесцельно брел по авенида дель Сид, тщетно пытаясь собраться с мыслями. На брусчатке под ногами мелькали смутные тени, водка еще не выветрилась из головы. Все происходящее напомнило ему нечеткую фотографию. Мысли его то и дело возвращались к Сьюзан: он надеялся, что она уже прослушала его голос на автоответчике. Чуть впереди, у остановки, притормозил городской автобус.

Человек смерил его сердитым взглядом: - Pues sientate. Тогда сядьте. Вокруг послышалось шушуканье, старик замолчал и снова стал смотреть прямо перед. Беккер прикрыл глаза и сжался, раздумывая, сколько времени продлится служба. Выросший в протестантской семье, он всегда считал, что католики ужасно медлительны.

It roughly translates as: "You know, when you start to calculate, you inevitably end up cheating.
