The present paper discusses the relativistic Doppler effect and tries to found misunderstandings in the present state of the Special theory of relativity. The author's conclusion that he found some “blue shift” which contradicts with time dilation is wrong. The weakest feature of the paper is that although the formulas, presented by authors, are in general correct, but they do not support the conclusions the author extract from them, and mistake is hidden in the interpretation. Let's focus on the plane waves. In general, the transverse Doppler effect, as it is studied in the available literature, means that an observer (let's call him the 1st observer), that receive an electromagnetic wave from a distant source, moving relative to the observer, will measure the wave frequency ν'=ν/γ, where γ=1/(sqrt(1-β²)), β²=u²/c², provided that the angle between the wave direction and the vector of the motion of the source, measured by the observer, is equal to π/2 (α'=π/2). So the light from moving source is red-shifted. It is generally treated as a pure effect of the special theory of relativity, and is due to the time dilation. Indeed, the observer can treat the wave crests as a clock, and the decrease of it's frequency is the actual time dilation. This effect is called as pure relativistic, as it is absent in the classical theory. It is quite clear and well-known fact in the special relativity. Note, that the distance between source and the 1st observer does not change in time, while being measured by the 1st observer. All the issues, raised by the author, are due to the fact, that the author decided not to use α', but α as an angle, that is equal to π/2, in order to define transverse Doppler effect. It is obvious, that α is the angle b... ... middle of paper ... ... relativity the simultaneousness is also relative. It is clear, that in case of uniform linear motion the time derivative of the distance between two objects is equal to 0 only once in time, at different time two objects either converge or move away. And in case of non-inertial reference frames, the special relativity is not applicable at all. Let me also comment on the example with spherical ways. The example should be treated with care, as the reference frame on the rim of the disk is non-inertial. The General relativity can handle this case correctly, this it is ok. But simplified direct conclusions from this example should not be extracted. And it will not help with our case with plane waves and inertial reference frames. To sum up: In my opinion the points raised by the author, are not correct. Therefore, I would not recommend it for publication in Plos One.
If you have ever read Einstein's Dreams, you can appreciate my dilemma. If you have not yet had the opportunity to experience this wonderful novel by Alan Lightman, I guarantee that after you read it you will expand your perception of the nature of time and of human activity. The novel is enchanting. It is a fictional account of what one of the greatest scientific minds dreams as he begins to uncover his theory of relativity.

The Big Bang theory is a theory that states that the universe originated as a single mass, which subsequently exploded. The entire universe was once all in a hot and dense ball, but about 20 million years ago, it exploded. This explosion hurled material all over the place and all mater and space was created at that point in time. The gas that was hurled out cooled and became our stellar system. A red shift is a shift towards longer wavelengths of celestial objects. An example of this is the "Doppler shift." Doppler shift is what makes a car sound lower-pitched as it moves further away. As it turns out, a special version of this everyday life effect applies to light as well. If an astronomical object is moving away from the Earth, its light will be shifted to longer (red) wavelengths. This is significant because this theory indicates the speed of recession of galaxies and the distances between galaxies.
This had a major impact on our result. As per the statistical analysis, the hypothesis created was incorrect, but the data was so far off, that our hypothesis was deemed incorrect when it is in
What was General Relativity? Einstein's earlier theory of time and space, Special Relativity, proposed that distance and time are not absolute. The ticking rate of a clock depends on the motion of the observer of that clock; likewise for the length of a "yard stick." Published in 1915, General Relativity proposed that gravity, as well as motion, can affect the intervals of time and of space.
Greene continues with his explanations of the special theory of relativity.Chapter 3: Of Warps and Ripples Green begins the chapter by describing "Newton's View of Gravity" and continues by discussing the incompatibility of Newtonian Gravity and Special Relativity. The author also talks about how Einstein discovered the link between acceleration and the warping of space and time. Greene also discuses the basic aspects of General Relativity. He later points out how the two theories of relativity effect black holes, the big bang, and the expansion of space.Chapter 4: Microscopic Weirdness This chapter describes, in detail, the workings of quantum mechanics.

This theory states that the speed of light in empty space will always have the same value regardless of the motion of the source or the motion of the observer. (Hewitt 286) Now, keeping this theory in mind, imagine you were on a train that was moving at the speed of light. You think you might have a piece of the hard-boiled egg you just ate in your teeth so you get out your phone and turn on the front camera. Can you see yourself? Einstein says you can because all laws of nature are the same in all uniformly moving frames of reference.
These theories attract the most attention, and are what have promoted the Bermuda triangle to the status of “Legend”. Now, let us explore some of the more prominent ones, namely the Electronic Fog theory, the Hutchinson effect, and government experiments with advanced radar at AUTEC naval base. Electronic Fog will be the first theory discussed in this paper. Electronic fog is a theory first publicized by Bruce Gernon, and several others have claimed to witness the fog, as they call it. Generally, it is described as a gray fog which causes instruments to go crazy, pilots and passengers become dizzy or unconscious, and in some cases, time warps.

Written by a renowned physicist, Albert Einstein, both passages were written for anybody who was interested in physics and economic ideologies. In the time when science and technology were rapidly developing, people sought for new information about physics and economy as they had to catch up with rapidly developing world. With developing technology, people, the audience of the passages A and B, had more access to media--which made Einstein’s high reputation as a physicist possible. Using different rhetorical approaches, such as qualifying language, grammatical tenses, and point of view, Einstein wrote passage A to explain the concept of physics--specifically, the relationship between time and space--while
The Doppler Effect is the shift in apparent frequency for an observer when a source of waves is moving towards or away from the observer, causing the pressure
In 1905, Albert Einstein wrote his paper on the special theory of relativity (Prosper). This theory has the reputation as being so exotic that few people can understand it. On the contrary, special relativity is simply a system of kinematics and dynamics, based on a set of postulates that is different from those of classical mec...
