Independentei 313, Bucharest 79590, Romania bGeographos, 1300 West Olive Avenue, Suite B, Burbank, California 91506-2225, USA Received 29 March 2004; received in revised form 7 July 2005; accepted 27 September 2005 Abstract Two particular stellar engines of class A and C, respectively, are described. When the Sun is the energy source, both of them provide practically the same thrust force. A simple dynamic model for Sun motion in the Galaxy is developed. It takes into account the (perturbation) thrust force provided by a stellar engine, which is superposed on the usual gravitational forces. Two different Galaxy gravitational potential models were used to describe Sun motion. The results obtained in both cases are in reasonably good agreement. Three simple strategies of changing the Sun trajectory are considered. For a single Sun revolution the maximum deviation from the usual orbit is of the order of 35–40 pc. Thus, stellar engines of the kind envisaged here may be used to control to a certain extent, the Sun movement in the Galaxy. However, under the constraints of present day technology this solution is not yet realistic. © 2005 Elsevier Ltd. All rights reserved. 1.

First, the interstellar transfer requires a way of controlling Sun (or star) movement in the Galaxy. Mirror In this paper, we study the amplitude of a possible human intervention on Sun revolution motion. A pre- Ψ vious approach of this subject was performed in [12]. Here we improve the early model and bring in original S contributions. In Section 2 we define the concept of stel- lar engine and give details about various stellar engine r classes. In Section 3 we develop a model for the motion of the Sun in the Galaxy, based on usual Newton dy- namics. The details of Sun movement are complex but (a) an “average” motion can be defined by using appropri- ate global Galaxy gravitational potentials. The move- ment is then studied in both the normal (unperturbed) Mirror T case and in the perturbed case, when an additional (stel- r lar engine) thrust force is acting on the Sun. To increase the confidence in results, two different global gravita- Sun tional potentials are used. Finally, in Section 5 we sum- Ψ marize the main findings of our work.

  • New Idea for Dyson Sphere Proposed 30 March 2015, by Bob Yirka
    New idea for Dyson sphere proposed 30 March 2015, by Bob Yirka that the massive amount of material needed to build such a sphere would be untenable, thus, a more likely scenario would be a civilization building a ring of energy capturing satellites which could be continually expanded. But the notion of the sphere persists and so some scientists continue to look for one, believing that if such a sphere were built, the process of capturing the energy from the interior sun would cause an unmistakable infrared signature, allowing us to notice its presence. But thus far, no such signatures have been found. That might be because we are alone in the universe, or, as Semiz and O?ur argue, it might be because we are looking at the wrong types of stars. They suggest that it would seem to make more sense for an advanced civilization to build their sphere around a white A Dyson Sphere with 1 AU radius in Sol system.

  • Dyson Spheres Around White Dwarfs Arxiv:1503.04376V1 [Physics.Pop-Ph] 15 Mar 2015
    Dyson Spheres around White Dwarfs Ibrahim_ Semiz∗ and Salim O˘gury Bo˘gazi¸ciUniversity, Department of Physics Bebek, Istanbul,_ TURKEY Abstract A Dyson Sphere is a hypothetical structure that an advanced civ- ilization might build around a star to intercept all of the star's light for its energy needs. One usually thinks of it as a spherical shell about one astronomical unit (AU) in radius, and surrounding a more or less Sun-like star; and might be detectable as an infrared point source. We point out that Dyson Spheres could also be built around white dwarfs. This type would avoid the need for artificial gravity technol- ogy, in contrast to the AU-scale Dyson Spheres. In fact, we show that parameters can be found to build Dyson Spheres suitable {temperature- and gravity-wise{ for human habitation. This type would be much harder to detect. 1 Introduction The "Dyson Sphere" [1] concept is well-known in discussions of possible in- telligent life in the universe, and has even infiltrated popular culture to some extent, including being prominently featured in a Star Trek episode [2]. In its simplest version, it is a spherical shell that totally surrounds a star to intercept all of the star's light. If a Dyson Sphere (from here on, sometimes \Sphere", sometimes DS) was built around the Sun, e.g. with same radius (1 AU) as Earth's orbit (Fig. 1), it would receive all the power of the Sun, 3:8 × 1026 W, in contrast to the power intercepted by Earth, 1:7 × 1017 W.

Wright , B. Mullan , S. SigurD sson , and M. S. Povich Accepted for publication in The Astrophysical Journal on 23 June 2014. ABSTRACT We motivate the Gˆ infrared search for extraterrestrial civilizations with large energy supplies. We discuss some philosophical difficulties of SETI, and how communication SETI circumvents them. We review “Dysonian SETI”, the search for artifacts of alien civilizations, and find that it is highly complementary to traditional communication SETI; the two together might succeed where either one, alone, has not. We discuss the argument of Hart (1975) that spacefaring life in the Milky Way should be either galaxy-spanning or non-existent, and examine a portion of his argument that we dub the “monocultural fallacy”. We discuss some rebuttals to Hart that invoke sustainability and predict long Galaxy colonization timescales. We find that the maximum Galaxy colonization timescale is actually much shorter than previous work has found (< 109 yr), and that many “sustainability” counter- arguments to Hart’s thesis suffer from the monocultural fallacy. We extend Hart’s argument to alien energy supplies, and argue that detectably large energy supplies can plausibly be expected to exist because life has potential for exponential growth until checked by resource or other limitations, and intelligence implies the ability to overcome such limitations. As such, if Hart’s thesis is correct then searches for large alien civilizations in other galaxies may be fruitful; if it is incorrect, then searches for civilizations within the Milky Way are more likely to succeed than Hart argued.
