{"title":"What Connects Dark Matter and Black Holes? Scientific Explanation","authors":"Russell Bagdoo","doi":"10.9734/bpi/rtcps/v1/3910f","DOIUrl":"https://doi.org/10.9734/bpi/rtcps/v1/3910f","url":null,"abstract":"Dark matter is a major component of the universe, about six times more abundant than ordinary visible matter. We measure the effects of its mass, but it escapes the telescopes. It has the particularity of emitting no radiation and interacting only by the action of gravity. The main purpose of this article is to try to answer what dark matter is: we conjecture that it is composed of magnetically charged neutrinos, true magnetic monopoles. But that requires a huge conceptual leap: Maxwell's laws must be inverted and the electric charge becomes a magnetic charge. Asymmetric \"reversed\" Maxwell's laws would provide the \"dark\" magnetic charge that would replace the electric charge. The very form of the Dirac equation, which imposed on ordinary matter that the particle carries an electric charge and obeys the principal properties of the electron, would impose in the dark matter that the \"dark\" particle obeys the main properties of a neutrino associated with a magnetic charge. Dark matter is intimately related to black holes. The darkness of dark matter and black holes is caused by the reversal of Maxwell's laws. The second aim of the article is to show that dark matter is derived from black holes, mainly from active supermassive black holes. This requires a second conceptual leap: the horizon of the black hole undergoes a high temperature and an intense pressure of magnetic fields which cause a blackout and a phase transition (or broken symmetry) when the matter crosses the horizon. The result is a reversal of Maxwell's laws: A magnetic charge is substituted for the electric charge, and the electric current becomes a tributary of the magnetic current. A third important conceptual leap follows: sterile magnetic neutrinos created inside the black hole would cross the horizon to the outside to constitute dark matter.","PeriodicalId":20935,"journal":{"name":"Research Trends and Challenges in Physical Science Vol. 1","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2021-08-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"86175027","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

With an additional biasing resistance, the proposed amplifier generates higher amplifier current gain (12904), higher amplifier voltage gain (304.343), wider bandwidth (2.7107 MHz) and higher power gain (65.940 dB-Watt) than earlier announced commercial BJTs based NPN Sziklai pair Small-signal amplifier. It is also found capable of producing distortion-less and fair output for a 1(mu)V-1.6mV range of AC input signal at 1KHz frequency. Low input and output noises along with excellent thermal stability over the operational temperature range -30oC (le)T(le)+50oC are the paramount features of this amplifier. Proposed amplifier is also examined with the matched pair of BJTs. An investigation of the physical analysis of frequency responses and related parameters such as the effect of additional biasing resistance RA, effect of variation of current gain factor (beta), temperature dependency, noise sensitivity, phase variation, range of the different biasing resistances and capacitors and small-signal AC analysis is also being performed in detail. With the suggested modifications, the proposed amplifier may be used in analog front-end amplifiers for monitoring the bio-potential signal of the human body. Tuning performance also makes it a suitable candidate to be used in radio and TV receiver stages.","PeriodicalId":20935,"journal":{"name":"Research Trends and Challenges in Physical Science Vol. 1","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2021-08-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"83647579","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The basal wing part of the dragonfly corrugated aerofoil structure used in this study was placed around the radius of the forewing. These corrugations define the stressed skin structure, which is made up of grider-like veins and a thin cuticle membrane that provides a sophisticated mechanical advantage for longitudinal bending resistance while allowing for wing camber and torsion. Dragonflies are recognised for their amazing flight abilities. They are designed to carry both aerodynamic and inertial loads. At a Reynolds number of 15000, a computational analysis of a newly designed dragonfly corrugated aerofoil is performed, with flow assumed to be laminar, steady, incompressible, and two dimensional. The project includes static structural analysis and aerodynamic flow analysis of a 2-D dragonfly corrugated aerofoil utilising Ansys Fluent and Ansys Mechanical APDL. It has been discovered that the design criteria employed, as well as simulations performed on a corrugated aerofoil, produce significantly better results than earlier studies. The structural analysis also demonstrates that it can withstand maximum pressure loads and provides high rigidity to the wing span. This discovery adds to our knowledge of insect-inspired corrugated wing structure and facilitates the application for improved design of artificial wings for MAVs and UAVs.","PeriodicalId":20935,"journal":{"name":"Research Trends and Challenges in Physical Science Vol. 1","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2021-08-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"86297722","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
