Implications of Michelson-Morley experiment, using sound waves.

Not Every Reference Frame is an Enclosed Compartment

It is a premise of the Galilean principle of relativity that every reference frame behaves mechanically like an enclosed compartment at rest.  As a consequence of this premise it is presumed to be mechanically impossible to discern the motion of any reference frame by observing experiments conducted within that reference frame.  Material objects in flight within an enclosed compartment will manifest a particular velocity that arises from momentum transfer through physical contact with the compar

THE NON-APPLICABILITY OF ADDITION OF VELOCITIES TO PROPAGATING SOUND WAVES

On a windless day a train of length L  travels along a level straight section of track at the constant velocity v.  An observer in the caboose has a clock and a light source with which she will send a signal to the engineer at the front of the train.  Upon seeing this signal, he will blow the whistle which will send out a sound wave that has the constant velocity c  through the still air/medium.   At this short distance a light signal is effectively instantaneous so upon sending the li

AN APPLICATION OF SOUND WAVES TO THE SPECIAL RELATIVISTIC DEFINITION OF SIMULTANEITY

Einstein’s Special Theory of Relativity defines simultaneity as: if two spatially separated events occur such that the light waves generated by these two events arrive at the midpoint of the line adjoining them, at a same time t, then these two events are considered simultaneous.  However, if these two events occur in open still air -- which is disengaged from the motion of a material object through space -- then any sound waves that might also be generated at the light flash events may not arri

Acoustic Simultaneity

According to relativistic mechanics, two events occur simultaneously if the light from each of these two spatially separated events meet at the midpoint of the line adjoining them, at the same time. Additionally if this simultaneity occurs in a reference frame that is considered to be stationary, then the events will not be generally regarded as simultaneous in a reference frame that is moving with a linear constant velocity v relative to the stationary frame. This may be true for light waves,

To Which Reference Frame Does the Air Belong?

The question I want to ask is: can the following thought experiment detect absolute motion, or will it detect a sort of intermediary motion; which is neither absolute motion, nor absolute rest? This intermediary motion is like Einstein relative motion, but without using a Galilean or Lorentz transformation between reference frames. It comes about when sound waves are used to investigate the motion of material objects through a stationary or moving medium. This air/medium is in and amongst two r

In Search of Intermediary Motion

It is like Einstein relative motion, but without using a Galilean or Lorentz transformation between reference frames. It comes about when sound waves are used to investigate the motion of material objects through a stationary or moving medium.   According to Galileo, Newton, and Einstein, the principle of re

The Magick Carpet Ride

A young woman and her two wyrd sisters are practicing their mysterious magicks tonight. They will exercise their telekinetic and mathematical skills with the levitation of a massive material object. In their alchemical experiment they will test whether two events that would appear simultaneous in a reference frame that is at rest, would these events still appear simultaneous if the reference frame were in motion? Can she make the invisible, visible? It is a windless night, during the witching

The Wind

A young woman stands before a high flat concrete wall on a blustery day. She directly faces it, at a distance of L meters away. The wind sweeps down past the wall at the constant velocity v and blows directly perpendicular from the wall to her face. She feels compelled to shout at the wall in some way, but she takes the stopwatch from her pocket and decides upon the experiment that she shall perform (akin to the Michelson-Morley aether wind experiment). The formula for a sound wave to echo back

The Mechanical Event

According to Galileo, Newton, and Einstein, the classical principle of relativity states that no mechanical experiment can be done to detect absolute motion, or motion of a material object relative to an everywhere stationary medium (similar to Michelson-Morley). A common reformulation of this principle states that: ♦The velocity of any motion has different values for two observers moving relative to each other. The following thought experiment proposes to investigate this principle, that is, to

One Velocity, Two Reference Frames

According to Newton and Einstein, the principle of relativity states that no mechanical experiment can be done to detect absolute motion, or motion of a material object relative to a stationary medium (similar to Michelson-Morley). Common reformulations of this principle state that: 1) The velocity of a material object takes on the simplest formula, as seen by an observer at rest in a reference frame, no matter whether the reference frame is at rest, or moving with constant velocity, v. 2) The

The Effects of Air Velocity on Sound Waves

In the 1632 book entitled Dialogue Concerning the Two Chief World Systems by Galileo Galilei (translated by Stillman Drake), he presented his historically important ship thought experiment: “Shut yourself up with some friend in the main cabin below decks on some large ship and have with you there some flies, butterflies, and other small flying animals. Have a large bowl of water with some fish in it; hang up a bottle that empties drop by drop into a wide vessel beneath it. With the ship standin

The reply to Milner Post

http://cs.astronomy.com/asy/general_discussion/f/27/t/55764.aspx?page=2#507568 Well, you have inspired a new thought experiment in my brain. Corresponding with you is helping to focus my thoughts. So, one of the main ideas of my hypothesis is that the source and the receiver of the waves, light or sound, are paired in a tandem such that the source and receiver are moving in the same direction, at the same constant velocity, v. I am trying to exploit this “tandemness” to analyze the mot

http://cs.astronomy.com/asy/general_discussion/f/27/t/55764.aspx?page=2#507568 Thank you Gerry, for creating this thought experiment. It’s kind of like having a puzzle to solve. Trying to see which pieces fit and which don’t. Even though I might answer as though I might know something I could quite possibly be wrong on some points, so please don’t take offense at me or my ignorance. So here goes. Two spaceships are traveling, one behind the other, each at the same constant velocity suc

A Flash of Light

I introduce a modification to my thought experiment; it will expand the use of the lantern as a light signal by the caboose observer. This modification will pull the platform observer into the midst of the experiment. There is once again a train of length, L, moving at a constant velocity, v, along a level straight section of track on a windless day. Also, there is again an operator in the engine car and an observer in the caboose car. The platform observer will now take on a more significant r

A Material Object In Space

As a material object makes its flight through the air (molecules / medium), it is a substantially different thing from a sound wave traveling through air. The principle of relativity holds the pair in a tension of physics contrariness. A material object making a straight line flight at constant velocity through space (air / medium), is seen to have two different velocities, when viewed by two different observers, in two different frames. One frame is considered as being at rest, and the other

Song from the Black Hole

http://chandra.si.edu/photo/2003/perseus/ I have recently learned about the concept that sound travels through Space. At Harvard’s Chandra X-Ray Observatory they found that the collapse of a Black Hole causes sound waves that travel through interstellar space. Empty space is not a pure vacuum; it has got stuff in it! There is cosmic dust, high-energy particles and magnetic fields in the so-called vacuum of space; that can be detected as evidence of sound waves across thousands of light years of

Max Born

The principle of relativity as annunciated by Galileo, Newton, Einstein and many others states that: ♦ There is no mechanical experiment that can be done to detect absolute motion. A form of this statement is the first postulate of the STR by Einstein. This principle can be rephrased in many formulations, which I will show are all violated by my proposed thought experiment (statement formulations are from Einstein’s Special Theory of Relativity by Max Born). 1.) The laws of mechanics have exactl

Caboose 3: A Reversal - Meeting & Overtaking

If the train were to come to a complete stop, then begin to move in reverse for a few kilometers, at a new constant velocity, v, with the caboose leading and the engine following; then this would create a new situation and require a new formula. This new formula could be considered to represent the sound wave overtaking (or catching up to) the caboose; it is a windless day, the air molecules (medium) are at rest. This leads to the following formulas related to meeting and overtaking of the sound

Jupiter's Delays

The mathematical value of the speed of light, c was first discovered as being very large, but finite, by Danish astronomer Olaf Roemer in 1676. During his astronomical observations of Jupiter and the eclipses of its many moons, he calculated the speed of light to a very close approximation. The light covered across the vast distance to the Earth, L, as the moon ventured in and out of Jupiter‘s shadow, at various points of the yearly seasons as both planets orbited the Sun. He was able to compare

Caboose 2: The Solution

The principle of relativity as annunciated by Galileo, Newton, Einstein, and others, states that no mechanical experiment can be done in an enclosed room that could detect the absolute motion of the room. There may not be anything such as absolute motion, only statements of relative motion expressed by mathematical formulas; but I hypothesize that the following thought experiment outlines a way of defining an intermediary motion that arises from some Aether, that resides between absolute motion

LIGO not LEGO: Sound &LIght

http://en.wikipedia.org/wiki/LIGO The artifice underlying Einstein’s STR is the mathematical construct that the two reference frames are represented by different equations, or laws of motion; but from within a reference frame an observer cannot distinguish whether he or she is in motion or at rest, based on mathematical observations from within the reference frame. An outside observer can make the distinction. For sound waves, my thought experiment shows that these formulas are the same and are

Pace Car 1: Sound & Light

A scene is acted out in the theatre of her mind, as kilometer post after kilometer post silently count the length of her journey. It is the principle of relativity that struts and storms across the stage. According to which, all laws of motion take their simplest form within a single inertial reference frame when that reference frame is attached to a body. In any other reference frame considered attached to a moving observer then there is defined a Galilean transformation which defines a math

Time Dilation: Acoustic Relativity

Under the Special Theory of Relativity, the units of time are to be measured in terms of a triangle formed by a reflected light bean. This gives rise to the effect of time dilation appearing between an observer in motion and an observer at relative rest. The phenomenon of time dilation is, however, indiscernible for the observer who shares in the motion. If a sound wave is used to measure the unit of time, the time dilation assumes a cloak of invisibility. The dilation appears only slightly

Length Contraction: Acoustic Relativity

Under the Special Theory of Relativity, the units of length are to be measured in terms of a triangle formed by a vertically reflected light bean. This gives rise to the effect of length contraction appearing between an observer in motion and an observer at relative rest. The phenomenon of length contraction is however indiscernible for the observer who shares in motion. If a sound wave is used to measure the unit of length, the length contraction becomes enshrouded in a mist. The contracti
