Dyson sphere

Dyson sphere
Dyson sphere is a hypothetical megastructure that completely encompasses a star and hence captures most or all of its power output. It was first described by Freeman Dyson. Dyson speculated that such structures would be the logical consequence of the long-term survival and escalating energy needs of a technological civilization, and proposed that searching for evidence of the existence of such structures might lead to the detection of advanced intelligent extraterrestrial life. Different types of Dyson spheres correlate with information on the Kardashev scale. Since then, other variant designs involving building an artificial structure or series of structures to encompass a star have been proposed in exploratory engineering or described in science fiction under the name "Dyson sphere". Origin of concept[edit] Feasibility[edit] Some ideas to build a fixed-in-place 'Dyson sphere' are currently beyond humanity's engineering capacity. Variants[edit] Dyson swarm[edit] Dyson bubble[edit] Related:  Science Fiction, Fantasy, Horror

Free Online Course Materials | Courses Antimatter In particle physics, antimatter is material composed of antiparticles, which have the same mass as particles of ordinary matter but have opposite charge and other particle properties such as lepton and baryon number. Encounters between particles and antiparticles lead to the annihilation of both, giving rise to varying proportions of high-energy photons (gamma rays), neutrinos, and lower-mass particle–antiparticle pairs. Setting aside the mass of any product neutrinos, which represent released energy which generally continues to be unavailable, the end result of annihilation is a release of energy available to do work, proportional to the total matter and antimatter mass, in accord with the mass-energy equivalence equation, E=mc2.[1] Antiparticles bind with each other to form antimatter just as ordinary particles bind to form normal matter. For example, a positron (the antiparticle of the electron) and an antiproton can form an antihydrogen atom. History of the concept Notation Positrons

Kardashev scale Measure of the evolution of a civilization according to its energy consumption Energy consumption in three types of civilization as defined by Sagan's extended Kardashev scale The Kardashev scale (Russian: Шкала Кардашева, romanized: Shkala Kardasheva) is a method of measuring a civilization's level of technological advancement based on the amount of energy it is able to use. The measure was proposed by Soviet astronomer Nikolai Kardashev in 1964[1] and came to bear his name. The scale is hypothetical, and regards energy consumption on a cosmic scale. Kardashev first outlined his scale in a paper presented at the 1964 Byurakan conference, a scientific meeting that reviewed the Soviet radio astronomy space listening program. A type I civilization is able to access all the energy available on its planet and store it for consumption.A type II civilization can directly consume the energy of a star.A type III civilization is able to capture all the energy emitted by its galaxy. Type I[edit]

Moonfall (film) 2022 film by Roland Emmerich The film was theatrically released in the United States on February 4, 2022, by Lionsgate and Summit Entertainment, and in the United Kingdom on the same day by Entertainment Film Distributors. It became one of the largest box-office bombs of all time, grossing only $67 million worldwide, and received mixed-to-negative reviews from critics. In 2011, astronauts Brian Harper, Jocinda "Jo" Fowler, and newcomer Marcus are on a Space Shuttle mission to repair a satellite. A mysterious swarm of alien technology attacks the orbiter, killing Marcus and knocking Jo unconscious before tunneling into the surface of the Moon. Brian, the only witness to the swarm, returns the crippled shuttle to Earth, but his story is dismissed and he is fired from NASA. Ten years later, conspiracy theorist K.C. As lunar orbit deteriorates, the Moon falls closer and closer to Earth, causing seismic and gravitational disturbances. Writer, director, and producer Roland Emmerich

Home ENG - Leonardo da Vinci | OFFICIAL WEBSITE Here is a new way for you to engage history and culture. This portal, the exhibitions, publications and everything involved in the “Leonardo3” project are the result of research activities and work carried out by L3’s founding partners, Mario Taddei and Edoardo Zanon. Leonardo3 (L3) is an innovative media company (research laboratory, creation of exhibitions and museums; editorial, television and multi-media projects; publishing house). Our mission is to study, interpret and make our artistic and scientific heritage available and enjoyable to the general public through the use of innovative techniques. In our work, we place particular importance on three-dimensional (3D) reconstructions, hence the “3” in the name Leonardo3. As part of our efforts to promote the work of da Vinci, we have created a digital version of the Codex Atlanticus.

Fusion power The Sun is a natural fusion reactor. Fusion power is the energy generated by nuclear fusion processes. In fusion reactions, two light atomic nuclei fuse to form a heavier nucleus (in contrast with fission power). Background[edit] Binding energy for different atoms. Mechanism[edit] Fusion happens when two (or more) nuclei come close enough for the strong nuclear force to exceed the electrostatic force and pull them together. Theoretically, any atom could be fused, if enough pressure and temperature was applied.[2] Mankind has studied many high energy fusion reactions, using particles beams.[3] These are fired at a target. Cross Section[edit] The fusion reaction rate increases rapidly with temperature until it maximizes and then gradually drops off. where: Lawson criterion[edit] This equation shows that energy varies with the temperature, density, speed of collision, and fuel used. η, is the efficiency with which the plant captures energy Density, Temperature, Time: ntτ[edit] Other[edit]

Warm-Blooded Plants and Freeze-Dried Fish by Freeman J. Dyson At that time most of the shuttle missions were carrying unmanned satellites into orbit for various purposes -- some scientific, some commercial, and some military. These launching jobs could just as well have been done automatically. Only a few of the shuttle missions really need people on board, to do experiments or to repair the Hubble Space Telescope, for example. After failing to eviscerate the shuttle, I wandered into the museum of the Johnson Space Center, where there is a collection of rocks that astronauts brought back from the Moon. It seemed like a miracle. Things have changed since then. The Europa Ocean NOTHER place where life might now be flourishing is in a deep ocean on Jupiter's satellite Europa. To land a spacecraft on Europa, with the heavy equipment needed to penetrate the ice and explore the ocean directly, would be a formidable undertaking. Freeze-dried fish orbiting Jupiter is a fanciful notion, but nature in the biological realm has a tendency to be fanciful.

Split (2016 American film) Film by M. Night Shyamalan Split is a 2016 American psychological thriller film written, directed and produced by M. Principal photography began on November 11, 2015, in Philadelphia, Pennsylvania. Kevin Wendell Crumb, a man struggling with dissociative identity disorder (DID) rooted in his history of childhood abuse and abandonment, has been managing living with his 23 distinct personalities well for several years with help from his therapist, Dr. Just outside Philadelphia, Dennis kidnaps three girls — Claire, Casey and Marcia — when they are waiting in the car of Claire's father to get driven home from a birthday party. Dr. Neurotheology: This Is Your Brain On Religion Principles of NeurotheologyBy Andrew B. NewbergPaperback, 284 pagesAshgateList price: $29.95 "Neurotheology" is a unique field of scholarship and investigation that seeks to understand the relationship specifically between the brain and theology, and more broadly between the mind and religion. If neurotheology is to be considered a viable field going forward, it requires a set of clear principles that can be generally agreed upon and supported by both the theological or religious perspective and the scientific one as well. It is important to infuse throughout the principles of neurotheology the notion that neurotheology requires an openness to both the scientific as well as the spiritual perspectives. In short, for neurotheology to be successful, science must be kept rigorous and religion must be kept religious. When considering the primary reasons for developing neurotheology as a field, we can consider four foundational goals for scholarship in this area. 1. 2. 3. 4.

Star lifting Star lifting is any of several hypothetical processes by which a highly advanced civilization (at least Kardashev-II) could remove a substantial portion of a star's matter in a controlled manner for other uses. The term appears to have been coined by David Criswell. Stars have deep gravity wells, so the energy required for such operations is large. For example, lifting solar material from the surface of the Sun to infinity requires 2.1 × 1011 J/kg. Methods for lifting material[edit] Thermal-driven outflow[edit] A mechanism for "harvesting" solar wind (RC = ring current, MN = magnetic nozzles, J = plasma jet). The simplest system for star lifting would increase the rate of solar wind outflow by directly heating small regions of the star's atmosphere, using any of a number of different means to deliver energy such as microwave beams, lasers, or particle beams – whatever proved to be most efficient for the engineers of the system.

Mars sample return mission Sample return concept A Mars sample return mission (MSR) would be a spaceflight mission to collect rock and dust samples from Mars and to return them to Earth. Sample return would be a very powerful type of exploration, because analysis is freed from the time, budget, and space constraints of spacecraft sensors.[1] All of Earth's laboratories could potentially study a sample.[1] According to Louis Friedman, Executive Director of The Planetary Society, a Mars sample return mission is often described by the planetary science community as the "holy grail" of robotic space missions, due to its high expected scientific return-on-investment.[2] Over time, several missions were planned but none of the proposed missions got beyond the planning phase. MSR was the highest priority Flagship Mission proposed for NASA by the Planetary Decadal Survey 2013-2022: The Future of Planetary Science.[3] Scientific value[edit] History[edit] SCIM[edit] NASA-ESA plan[edit] NASA proposals[edit] Additional plans[edit]
