    About this ebook

    When Einstein first published his Theory of Special Relativity paper, it was said that only a handful of people understood it. This is due in no small part to the "against everyday or common experiences" or apparent weirdness of the ideas. The main tenet of the theory is the constancy and maximum limit of the speed of light at 186,000 miles per second, which is actually against common sense. To explain this constancy, Einstein brought up time dilation and length contraction. However, in this book Dr Richard Banner posits with an explanation and example that time dilation alone, which is an experimentally proven phenomenon, is sufficient for the explanation of the constancy of the speed of light, without the need of bringing into play length contraction, which is only an inference with no experimental proof. He also explains the possibility of exceeding the speed of light. Dr Banner has published a number of research articles on relativity and quantum theory.

      A Study Of The Special Theory Of Relativity - Richard Banner

      PREFACE

      The Special Theory of Relativity is a very important piece of work in physics. It is a work of recognised great genius which has made its creator Albert Einstein famous as well as the icon for genius.

      This book is a survey of the famous theory with alternative views and suggestions.

      1 ANOMALY IN COMPUTING SPEED OF LIGHT

      The Special Theory of Relativity postulates that the speed of light always remains constant at 186,000 miles per second at all inertial frames. This chapter describes an anomaly in the standard computation pertaining to the constancy of the speed of light.

      The Special Theory of Relativity posits that a person on a moving vehicle, e.g., a very fast moving train (moving frame), traveling at close to the speed of a beam of light (moving frame) in the same direction would find the speed of the beam of light (moving frame) to be unchanged at 186,000 miles per second, instead of the difference between the speed of the very fast moving train (moving frame) and the speed of the beam of light (moving frame), which would normally be the case. This is because, according to the Special Theory, on the very fast moving train (moving frame) approaching the speed of light the clock therein used to gauge the time traveled by the beam of light (moving frame) has slowed down by the same degree (say X %) as the ruler or measuring device (stated as meter stick or measuring rod in some texts) therein used to gauge the distance traveled by the beam of light (moving frame) has contracted in length in the direction of the very fast moving train’s motion (also X %), the greater the very fast moving train’s traveling speed the more the clock slows down and the greater the length contraction of the ruler or measuring device. This is expressed in the following equation (the speed of the beam of light (moving frame) being the distance it traveled divided by the time it took to travel this distance), which is in accordance with the Special Theory of Relativity:-

      (186,000 miles  -  X % of 186,000 miles)  ÷  (1 second  -  X % of 1 second)  =  186,000 miles per second

      In other words, there has to be a same percentage decrease in the time gauged and the distance gauged due to the respective slowing down of the clock and contracting in length of the ruler or measuring device therein the very fast moving train (moving frame), in order for the speed of the beam of light (moving frame) to remain constant, which is consistent with mathematical logic - this condition must indeed apply in order for the speed of the beam of light (moving frame) to remain constant.

      There is however something not quite usual related to the above concept. According to the Special Theory of Relativity, the person on the very fast moving train traveling at close to the speed of light (moving frame) gauging the speed of the beam of light traveling in the same direction (moving frame) would not notice that the clock on his very fast moving train (moving frame) has slowed down and the ruler or measuring device therein has contracted in length in the direction of motion. In other words, everything would appear normal to him, despite the fact that his clock has actually slowed down and his ruler or measuring device has actually contracted in length in the direction of motion, as is postulated by the Special Theory of Relativity. But, according to the Special Theory of Relativity, when he (moving frame) compares himself to a person on the ground who is not moving (stationary frame), he could even consider himself stationary (stationary frame) while thinking that the person on the ground (who is not moving) is actually moving (moving frame), i.e., all movements are relative. He (moving frame) would notice that the clock on the ground (stationary frame) is slower and the ruler or measuring device on the ground (stationary frame) is shorter. The person on the ground who is not moving (stationary frame) would also notice that the clock on the very fast moving train (moving frame) is slower, the ruler or measuring device therein is shorter, and, the length of the very fast moving train (moving frame) is shorter. In other words, both the train-traveler (moving frame) and the person on the ground who is not moving (stationary frame) would notice that the other’s clock is slower and the other’s ruler or measuring device is shorter, and, according to the Special Theory of Relativity, the slowing down of clocks and the shortening of rulers or measuring devices would appear to be by the same degree (X %) for both.

      But, it is actually the clock on the very fast moving train traveling at close to the speed of the beam of light in the same direction (moving frame) which has slowed down and the ruler or measuring device therein which has contracted in length (in the direction of motion) as is postulated by the Special Theory of Relativity, and not those on the ground (stationary frame). To the traveler on the very fast moving train (moving frame) who is gauging the speed of the beam of light traveling in the same direction (moving frame), the beam of light (moving frame) appears to take less time (time dilation) to travel a shorter distance (length contraction), which, according to the Special Theory of Relativity and in accordance with the following equation, explains the constancy of the speed of light at all inertial frames:-

      (186,000 miles  -  X % of 186,000 miles)  ÷  (1 second  -  X % of 1 second)  =  186,000 miles per second

      The speed of the beam of light (moving frame) is obtained by dividing the distance traveled by the beam of light (as gauged by the ruler or measuring device on the very fast moving train traveling at close to the speed of light - moving frame) by the time it took to travel that distance by the beam of light (as gauged by the clock therein the very fast moving train - moving frame), the gauging being carried out by the traveler on the very fast moving train (moving frame). In the above example, the clock on the very fast moving train traveling at close
