7. Fundamental Physical Constants, Constant The Dovada four dimensional atomic model, fundamental physics constants successfully defined from first principles. http://www.dovada.com/constants.htm

Fundamental physical constants what are they? We have found that there are certain limits to how far we can visualise and understand the workings of the Universe. There exists an observable limit, which we cannot go past, this limit is related to the speed of light. Currently the speed of light has fuelled much debate in the areas of relativity and other similar theories, mostly based purely on speculation. When we attempt to grasp the concepts of these speculative theories, the theory developers often hide behind the unknown facts, facts like it is not possible to exceed this speed of light or time slows as you approach and stops if you could travel at the speed of light etc., We have all heard the stories over the decades. Click here for a comprehensive list of physical constants. In the 1920’s Edwin Hubble conceived a method of proving that our universe was expanding. This he did by measuring the frequency of light received on Earth from distant galaxies and concluded that objects in space are moving away from us. This is accomplished by measuring the spectra of certain known elements. This theory is based on the assumption that the speed of light is a constant condition throughout the Universe. Light emitted from a moving body will appear to have a different wavelength if moving towards or away from another relative body in space. Structures, like galaxies, receding away from our relative position in the universe have a red shifted wavelength, these are longer waves whereas if an object is approaching us we would have a blue shifted or shorter wavelength. This effect is similar to the frequency shift from a cars horn as the car zooms by and passes us.

Physical constant From Wikipedia, the free encyclopedia Jump to: navigation search A physical constant is a physical quantity that is generally believed to be both universal in nature and constant in time. It can be contrasted with a mathematical constant , which is a fixed numerical value but does not directly involve any physical measurement. There are many physical constants in science, some of the most widely recognized being the speed of light in vacuum c , the gravitational constant G Planck's constant h , the electric constant , and the elementary charge e . Physical constants can take many dimensional forms: the speed of light signifies a maximum speed limit of the universe and is expressed dimensionally as length divided by time ; while the fine-structure constant α, which characterizes the strength of the electromagnetic interaction, is dimensionless Contents Dimensional and dimensionless physical constants How constant are the physical constants? Anthropic principle Table of universal constants ... edit Dimensional and dimensionless physical constants Whereas the values of physical constants do not depend on the unit system used, the numerical values of dimensionful physical constants do depend on the unit used. Therefore, these numerical values (such as 299,792,458 for the constant
