Light, speed

As I discuss in Time A Traveler s Guide, we now know that time travel need not be confined to science fiction or Hollywood movies. Time travel is possible. For example, an object traveling at high speeds ages more slowly than a stationary object. This means that if you were to travel into outer space and return, moving close to light-speed, you could travel thousands of years into the Earth s future. In addition to highspeed travel, researchers have proposed numerous ways in which time machines can be built that do not violate any known laws of physics. These methods allow you to travel to points in the world s past or future. 

When a scalar potential is set upon a transmission line, it speeds down the line at nearly light speed, revealing its vector nature. When it is set onto the middle of the transmission line, it speeds off in both directions simultaneously, revealing its bidirectional vector nature. In addition to this observation, there is rigorous mathematical proof as well. 

The refractive index, nD, defined as the ratio of light speed at the sodium D-line in a vacuum to that in the medium, is used in obtaining the polarizability, a, of solvent molecules. The relationship between a and nD is given by a = (3Vm/ 4 rNA)( D-l)/(wD + 2), where NA is the Avogadro constant and Vm is the molar volume.4 Solvent molecules with high a-values tend to interact easily with one another or with other polarizable solute particles by dispersion forces.5 ... 

Vertex B. Electron with momentum /v/.i interacts with momentum pstc- An important assumption is made here. It has already been mentioned that in Ref. 5 the possibility for existence of STC around nucleons and atoms is predicted, and elaborated on in Ref. 16. It is assumed that in the electron-cesium atom interactions, distortion of the STC around the atom is taking place. As a result of this STC distortion, the momentum Pstc is created, which is added to the electron momentum. The resultant momentum of the electron then will be pes = Pek +psic- As a result of STC distortion, the electron will be in motion with faster than light speed in the STC between cesium atoms. Hence, at the vertex B, the superluminal process is taking place. 

The possible existence of faster-than-light objects has a long history, which, since the early 1900s, can be traced back in pre-relativistic times) to J. J. Thomson and A. Sommerfeld (see the excellent review in Ref. 1 by Recami for a full historical account). After the advent of special relativity in 1905, light speed (the speed of light) in vacuum was considered as the maximal causal speed, as an upper limit for any velocity. Such a common belief lasted for about half a century, when the problem of faster-than-light particles was reconsidered...

It is now possible to introduce two simplifications rationalized as follows (i) since the selected applications will be usually operated at room temperatures, internal emission can be safely neglected (W = 0) and (ii) considering the magnitude of the light speed c, the first term is imequivocally neglected in all practical cases ( /c) dl /di) 0.

Construction on Provo has proceeded at light speed over the last decade, and developers have already carved out their plans for North Caicos, Ambergris Caye and Dellis Caye. So why push resort sprawl to West Caicos Why build up a small, environmentally unique island that s the site of two national parks ...
