LIGO Experiments Cannot Detect Gravitational Waves by Using Laser Michelson Interferometers—Light’s Wavelength and Speed Change Simultaneously When Gravitational Waves Exist Which Make the Detections of Gravitational Waves Impossible for LIGO Experiments

It is proved strictly based on general relativity that two important factors are neglected in LIGO experiments by using Michelson interferometers so that fatal mistakes were caused. One is that the gravitational wave changes the wavelength of light. Another is that light’s speed is not a constant when gravitational waves exist. According to general relativity, gravitational wave affects spatial distance, so it also affects the wavelength of light synchronously. By considering this fact, the phase differences of lasers were invariable when gravitational waves passed through Michelson interferometers. In addition, when gravitational waves exist, the spatial part of metric changes but the time part of metric is unchanged. In this way, light’s speed is not a constant. When the calculation method of time difference is used in LIGO experiments, the phase shift of interference fringes is still zero. So the design principle of LIGO experiment is wrong. It was impossible for LIGO to detect gravitational wave by using Michelson interferometers. Because light’s speed is not a constant, the signals of LIGO experiments become mismatching. It means that these signals are noises actually, caused by occasional reasons, no gravitational waves are detected really. In fact, in the history of physics, Michelson and Morley tried to find the absolute motion of the earth by using Michelson interferometers but failed at last. The basic principle of LIGO experiment is the same as that of Michelson-Morley experiment in which the phases of lights were invariable. Only zero result can be obtained, so LIGO experiments are destined failed to find gravitational waves.

Revelations from Historical Experiments on Constant Speed of Light

The postulate of constant speed of light for all reference frames is the foundation of relativity theories. The resultant time dilation and length contraction are generally accepted but still perplexing for most people. By re-examining the historical evidence, this paper confirms Einstein’s postulate and reveals the mechanism for the constant speed of light: the interaction between photons and matter can impart the speed of an inertial frame to the photons and thus result in the same speed of light for different inertial reference frames. This mechanism can consistently explain all major experiments on the constant speed of light.

Factors Influencing the Successful Adoption of Human Resource Information System: The Content of Aqaba Special Economic Zone Authority

This study examines the key factors that have impact on the successful adoption of Human Resource Information System (HRIS) within the Aqaba Special Economic Zone Authority (ASEZA)/Jordan. In order to accomplish the purpose of the study four critical factors are inquired. So, four critical factors are inquired: First, TAM Model (Perceived Ease of Use (PEOU) and Perceived Usefulness (PU)). Second, Information Technology Infrastructure (ITI). Third, Top Management Support (TMS). Finally, Individual Experience with Computer (IEC). The research model was applied to collect data from the questionnaires answered by 45 users of HRIS as a source of primary data, based on a convenience sample the response rate was about 91%. In addition, the results were analyzed by utilizing the Statistical Package for Social Software (SPSS). Furthermore, the findings were analyzed;multiple Regression analysis indicated that all research variables have significant relationship on successful adoption of HRIS. The findings indicated IT infrastructures have a positive and significant effect on the successful adoption of HRIS. But there is no significant of PU, PEOU, TMS, and IEC on the successful adoption of HRIS. Finally, the results indicated that no significant statistical differences of demographic characteristics on HRIS adoption. Depending on the research’s findings;the researchers proposed a set of recommendations for better adoption of HRIS in SEZA.

Interaction between an Accelerated Mass in Straight Motion and a Hidden Energy Reservoir as a Strict Mathematical Consequence of Special Relativity

A. Einstein and H.A. Lorentz had found that the mass of an accelerated body traveling at relativistic velocity appears to depend on whether the acceleration is performed in the direction of motion or in a transverse direction. E.P. Epstein rejected this result in the “Annalen der Physik”;he rather postulated an additional force that turns up when the body is accelerated in the longitudinal direction. It can be shown that the concept of an increased longitudinal mass is based on a simple mathematical error. When correcting this error, it turns out that Epstein’s additional, hidden force is indispensable in order to avoid an inner inconsistency of Special Relativity. It does most of the total work absorbed by the moving object, and is thus responsible for most of the increase in its energy (=mass), given the speed attained is relativistic. In other words: While the total force on the body needed to maintain a constant acceleration a0 is “(1-v2/c2)-1ma0=m0(1-v2/c2)-3/2a0”, the technical force needed to maintain that acceleration amounts only to “ma0=m0(1 - v2/c2)-1/2a0”. The total energy of two objects that undergo a symmetrical, elastic head-on collision is therefore not conserved during the collision, thus requiring the involvement of a hidden reservoir of energy. This result is confirmed by calculations that use the concept of momenergy. The phenomenon of an apparent disappearance of energy has been noticed in particle physics already (target-experiment), but its consequences have been ignored. Instead, an explanation has been given (reduced “energy of the center of mass”) which is inconsistent and violates the relativity principle.

Thoroughly Testing Einstein’s Special Relativity Theory, and More

Einstein’s Special Relativity (ESR) has enjoyed spectacular success as a mathematical construct and in terms of the experiments to which it has been subjected. Possible vulnerabilities of ESR will be explored that break the symmetry of reciprocal observations of length, time, and mass. It is shown how Newton could also have derived length contraction . Einstein’s General Relativity (EGR) will also be discussed occasionally such as a changed perspective on gravitational waves due to a small change in ESR. Some additional questions addressed are: Did Einstein totally eliminate the Ether? Is the physical interpretation of ESR completely correct? Why should there be a maximum speed limit, and should it always be the same? The mass-energy equation is revisited to show that in 1717 Newton could have derived the modern , and not known that it violates the foundation of his mechanics. Tributes are paid to Einstein and others.

泥石浆型复杂破碎岩体非线性渗流数学模型与实验研究

断层、陷落柱是影响承压水上煤层开采的主要隐患之一,由于其具有碎石块和泥质充填物(泥石浆)构成的复杂结构,其渗透性的确定通常以定性分析为主,缺少量化模型。为了研究泥石浆型复杂破碎岩体渗透性的量化计算方法,开展了渗流实验研究破碎岩体非线性渗流规律,并基于多孔介质分形理论、非线性渗流理论,建立了考虑黏土成分及泥化充填作用的破碎岩体非线性渗流数学模型,最后与实验结果对比验证数学模型的准确性。结果表明:①陷落柱破碎带样品的粒度分布具有一定的分形规律,含有黏土颗粒的破碎带岩体遇水泥化后,分形维数增大,黏土充填封堵了大颗粒岩石碎块内部的大孔隙,降低了破碎岩体的渗透性;②随着破碎带岩体渗透率的降低,非线性开始发生时的临界压力梯度也增大,表明非线性临界压力梯度可以用来量化破碎岩体的阻隔水能力;③非线性开始发生时的临界压力梯度的实验结果与数学模型计算结果吻合,验证了模型的准确性。建立的破碎岩体非线性渗流数学模型首次尝试考虑了黏土成分及泥化充填作用对渗透性的影响,为泥石浆型复杂破碎岩体渗透性的定量计算及水体下、承压水上等特殊开采条件下地质构造的阻隔水性能研究提供了一种新的研究思路。

Numerical simulation and experiment validation on lightning-induced effects of a special vehicle

In recent years, with the development of the system integration technology, the outside integrative special vehicles, such as big oil tank, trucks loading with dangerous goods and so on, are becoming more and more important. When the vehicle is under way, it will inevitably encounter the nature environment, including lightning. If the lightning strikes directly or very close to the vehicle, the lightning-induced effects will be very destructive. Therefore, for a better understanding of the lightning-induced effects produced on the special vehicle by the lightning strike, the research on lightning-induced effects of a special vehicle for aerospace system transportation was proposed. In the paper, a numerical simulation model for the special vehicle is established, the lightning-induced effects are analyzed successfully by using tram.smission-line matrix （TLM） algorithm, and the experiment validation example is also implemented. By comparing the numerical simulation with the actual experiment results, the correctness trend of the numerical simulation is validated and a mass of invaluable research data is obtained, which has a deep significance on the lightning research in our country.
