Gravity Constraints on the Measurements of the speed of light
收藏 引用
International Journal of Astronomy and Astrophysics 2019年 第3期9卷 265-273页
作者: Faical Ramdani Laboratory of Geophysics&Natural Hazards GeophysicsNatural Patrimony&Green Chemistry Research Center(Geopac)Mohamed V UniversityRabatMorocco
The speed of light in a vacuum is a constant of special relativity, electromagnetic wave theories, and astrophysical distances. However, several measurements of its speed (c) at locations on the Earth’s surface seem ... 详细信息

The Effect Density Has on the speed of light, Time, and the Dimensions of the Multiverse
收藏 引用
Journal of High Energy Physics, Gravitation and Cosmology 2022年 第4期8卷 935-939页
作者: Ardeshir Irani The Dark Energy Research Institute Downey California USA
We show that as the dimensions of the Multiverse increase so does its density. This increase in density has the effect of decreasing the speed of light, slowing down time, and increasing the life span of each higher d... 详细信息

light speed Expansion and Rotation of a Very Dark Machian Universe Having Internal Acceleration
收藏 引用
International Journal of Astronomy and Astrophysics 2020年 第3期10卷 247-283页
作者: U. V. S Seshavatharam S. Lakshminarayana Honorary Faculty I-SERVE Survey No-42 Hitech City Hyderabad India Department of Nuclear Physics Andhra University Visakhapatnam India
We present a Machian model of Quantum Cosmology with full dark matter and light speed expansion and rotation. During galaxy formation and evolution, fraction of dark matter transforms to visible matter with a relation... 详细信息

Negative and Superluminal Group Velocity Propagation with Narrow Pulse in a Coaxial Photonic Crystal
收藏 引用
Chinese Physics Letters 2007年 第3期24卷 624-627页
作者: 偶晓娟 周渭 李琳 滕李虎 冯宝英 郑胜峰 王凤伟 Department of Measurement and Instrument Xidian University Xi'an 710071
We investigate the propagation of electric signal along a spatially periodic impedance mismatched transmission line group. Anomalous dispersion is caused by the periodically mismatched impedance structure and a forbid... 详细信息

Is There an Absolute Scale for speed?
收藏 引用
Journal of Modern Physics 2022年 第8期13卷 1184-1196页
作者: Ricardo B. Ferreira Joã o B. Ferreira Instituto Superior de Agronomia University of Lisbon Lisbon Portugal Instituto Português de Oncologia de Lisboa Francisco Gentil Lisbon Portugal
Except for the speed of photons in vacuum, all speeds are relative. Could we develop an absolute scale for speed in which relative values for speed may be arbitrarily positioned and compared in absolute terms? The cur... 详细信息

The Impact of the Earth’s Movement through the Space on Measuring the Velocity of light
收藏 引用
Journal of Applied Mathematics and Physics 2016年 第6期4卷 1168-1178页
作者: Miloš Čojanović Independent Researcher Montreal Canada
Goal of this experiment is basically measuring the velocity of light. As usual we will measure two-way velocity of light (from A to B and back). In contrast to the similar experiments we will not assume that speeds of... 详细信息

The Impact of the Earth’s Movement through the Space on Measuring the Velocity of light(Part Two)
收藏 引用
Journal of Applied Mathematics and Physics 2017年 第3期5卷 741-757页
作者: Milos Cojanovic Independent Researcher MontrealCanada
In this paper is presented an experiment that has a goal to measure the speed of light in one direction, using one clock and one mirror. To achieve this, we have to make the measurements during the period of one year ... 详细信息
