Creating the discipline of gravity design

    I have three publications to share with the readers through the generosity of Prof. Dr. rer.nat. Jochem Hauser.

    The first is his review of the book […]

  • EHT gives rises to six fundamental forces, three of them of gravitational nature, and thus could lead to a novel type of propulsion without propellant. The following are quotations from a 2012 paper by Droscher and Hauser. It suggests that one of the three gravitational forces acts upon spacetime and underlies the cosmological constant responsible for the expansion of the universe. It is postulated that negative dark energy (attractive field) is attracted to the matter inside of a galaxy and that its antiparticle (repulsive field) is repelled by the interior matter and collects in the galactic halo where dark matter resides. This makes it a candidate for the explanations behind MOND, a leading alternative to dark matter that has been found to accurately predict the speed of stars within dwarf galaxies.

    On the Reality of Gravity-Like Fields

    “It is assumed that the dark energy is composed of both repulsive and attractive fields and only the combined action is perceptible in empty space. Inside galaxies, because of the large density of visible matter, the attractive field is neutralized and an additional gravitational interaction mediated in form of the MOND acceleration a0 has to be taken into account.”

    “Since no dark matter seems to reside within galaxies (ESO observations, June 2012), but, on the other hand the deviation from Newton’s law has been experimentally verified by McGaugh (February 2011), only the interaction of dark energy with visible matter inside the galaxy and the interaction with dark matter in the galactic halo remain to account for this modification of the gravitation law. Since the MOND hypothesis seems to give the correct value, any derivation should reproduce this value. As the measurements by Reyes and also galactic gravitational lensing have shown, both visible and dark matter are subject to Newton’s gravitational law.”

    “Moreover, since strong gravitational lensing is observed, galaxies must possess dark matter. Therefore, the physical mechanism for galactic halo formation has to be found, while, at the same time, the non-existence of dark matter inside galaxies must follow from the the same physical concept, and, finally, the correct value of the MOND acceleration needs to be produced. So far, no physical theory exists. Therefore, the attempt is undertaken to apply the novel concepts of EHT to try to solve this riddle.”

    “According to Loll et al. the computer simulations from Causal Dynamical Triangulation (which is a Monte Carlo simulation of the path integral for the action of GR, or summation over universes) without cosmological constant Λ > 0 do not lead to a four-dimensional spacetime in the classical limit. In other words, a repulsive gravitational force is mandatory, and thus the assumption of the existence of dark energy is justified also by computer simulation.”

    “It is known that within a galaxy, cosmic expansion does not take place. Instead, an additional acceleration field, a0, directed toward the center of the galaxy is present. Since dark matter cannot be present inside a galaxy, the existence of attractive dark energy is postulated, which according to EHT, would be represented by the antiparticle of the quintessence particle νq.”

    “The question arises, how the large density of ordinary matter inside a galaxy – remember that dark matter cannot be present – does act on the mixture of positive and negative dark energy that is ubiquitous in the Cosmos? The result is known, namely that inside a galaxy an acceleration a0 = 1.2 × 10−10 m/s2 pointing toward the galactic center must be obtained. Obviously, it can only be caused from the presence of negative dark energy (attractive gravitation), residing inside the galaxy, which is attracted by the visible matter inside as well as the dark matter in the halo of the galaxy. Both types of dark energy, positive (repulsive) and negative (attractive) are present throughout the Universe, but in the current era | Λ- |>| Λ+ |, and thus a resulting force leading to an expansion is acting on the space field.”

    “However, as will be shown next, the effect of Λ+ (contracting spacetime, but being repulsive with regard to the matter inside the galaxy because of its negative energy) is neutralized inside a galaxy, and therefore inside the galaxy only the attractive gravitational effect of Λ- on ordinary matter (both visible and dark) remains. The reason why the Λ+ is neutralized inside a galaxy, is due to the fact that a galaxy contains a large amount of ordinary matter, where visible matter is inside the galaxy and dark matter resides in the halo, with about 80% of the matter in the halo. To understand the qualitative physical mechanism of dark matter halo formation, consider a sphere filled with positive electric charges. It will repel particles arriving from outside the sphere that are of like charge, while attracting particles of negative electric charge. In the gravitational case, the νq particles are representing the cosmological Λ+ field and are repelled by the galactic matter, and thus are screened out. The νq particles, representing the Λ- field are attracted by the galactic matter, and thus are collected mainly in the halo, where matter density is larger. Thus, a surplus of νq particles is collected in the halo and, to a lesser extent, inside the galaxy, resulting in an acceleration acting toward the center of the galaxy, which is known as the MOND acceleration, being prevalent for visible matter in the vicinity of the halo. In this way, dark energy in combination with the dark matter halo seems to be responsible for the observed MOND acceleration.”

  • Today most practitioners of product design view the tenets of “human-centered design” (HCD) as more expansive than just for software interactions but still possessing a task focus, which has compelled perennial design thinker Donald Norman to warn of the downsides of following that process too closely. Though he has no qualms about the focus upo…[Read more]

    A more robust design configuration capable of generating sufficient lifting force for a space vehicle (shown at the top of this group) would need sufficient current to produce a much stronger acceleration field. In practice a larger disk and bigger coils would also be needed to lift such a mass. As suggested in their 2010 AIP study, this…[Read more]

  • Gravity-Superconductors Interactions: Theory and Experiment
    (Eds. Giovanni Modanese, Univ. of Bozen, Italy and G. A. Robertson, Institute for Advanced Research in the Space, U.S.A.) was published by Bentham Science Publishers (

    In Chap. 11, pp. 269-319, entitled: Emerging Physics for Gravity-like Fields, W. Droescher and J. H. Hauser present both experimental and theoretical evidence for gravitational engineering that is, the generation of laboratory generated gravitational fields. Extreme gravitomagnetic fields might be generated through a phase transition at cryogenic temperatures, triggering the conversion of electromagnetic into gravitomagnetic potentials. The physical model for this process is presented and the technology ensuing from this novel physical interaction with regard to propellantless propulsion, direct energy generation, and transportation in general is discussed.

    In the foreword, written by J. H. Hauser, the publisher has decided, without further consultation, to change the name of Wernher von Braun into Werner von Braun, obviously being unaware that Wernher is the correct first name of Prof. von Braun. The foreword by J. H. Hauser and the introduction to Chapter 11 can be downloaded here.

    Note: Be aware that for the above listed book, purchasing chapters or the full book online may encounter credit card fraud alerts… it did for me in the U.S., possibly because the publisher, Bentham Books, is located in the United Arab Emirates.
