In Response to James R claiming: no conceivable test can distinguish absolute motion. How to detect and measure the absolute velocity, the motion of two inertial frames, in free space. Despite the theoretical axiom that detection and measurement of absolute motion is impossible I will show the trivial correction to this kind of silliness. I do not intent=d any unnecessary insults here, but If there were ever a social class of those claiming scientific status from a position of sheer and unadulterated bigotry and bias it is the Special Relativity industry. Well any way here we go. The detection of absolute motion, AKA velocity Remote piloted vehicle velocity probe (RPVVP) Case 1; Va and Vb in a collision trajectory. First we have two inertial frames, Va and Vb, moving at some relative velocity say, 5000 standard units which to start we will assume is in the opposite direction to each other. By radar signal processing the 5000 unit speed number is verified by navigators on both frames. As the frames move toward each other Va launches a remote piloted velocity vehicle probe (rpvvp), an Aquila, that starts at Vq = Va and by successive accelerations in the dorectoion opposite tot hatassumed asVa, increases its velocity with respect to Va all the while making constant checks on the relative velocity of the Vq and Vb and Va. As Vq increases velocity the Vq – Vb relative velocity decreases until finally Vq = Vb and with Va, lets say the Vq frame had a measured 2000 unit relative velocity with respect to Va. Therefore, Va – Vb = Va – (-Vb) = 5000 and as Vb = 2000 Va = 5000 – 2000 or 3000 units. Case 2: Vb moving in the same direction as Va. Here Vq starts as before, but the first acceleration showed that Vq – Vb increasing, therefore the Vq decelerated and continued its motion in the same direction as Va and Vb. Using the same techniques of accelerating or decelerating as the measured relative velocity increased or decreased, the Vq arrives at the velocity Vq = Vb, which we will assume again was 2000 units. As Vq maintains a running relative velocity accounting with Va, we see that Va – Vb = 5000 and therefore Va = 5000 + Vb = 5000 + 2000 = 7000 units. Introduction to MUMPS (momentum measurement particles) analysis. Case 1: Va and Vb in relative motion with Va at actual rest, momentum = 0, (which will be determined). Va and Vb are moving in a collision course as shown here: Code: /----------------------------------/ Va -> <- \------------------------------------------------\Vb Our Mumps are small round objects much in the form of golf balls (in fact they are golf balls) as are the flat strip of surface on each inertial frame fabricated wihe same same surface configuration. As Va is actually at rest the observer on Vb will see a single line, as a mump is directed perpendicular to the motion of the two inertial frames: "o" ae the Va mumpstones, “|” Va observer. Code: /-------o----------------0---------/ Va = 0 o ¯ 0 0 o 0 0 o o 0 0 o o 0 0 o o 0 0 o o 0 0 o o 0 o o 0 ß \<------- -o-------|-----------|-|-|-0---------\Vb <- Vb observer “|” Now, as Vb is the only frame moving (left) the mumps directed to Va will move with the inertial frame and inherits the Vb velocity. When the Vb mumps strike the flat surface of Va there will be a friction induced force in the direction of motion of the Vb frame. Likewise, as Va is at rest her mumps will only be deflected from a straight line when striking the moving Vb frame. The Va observer will see her mumps deflected to her right, the readers left. As Vb is moving left he will see his mumps as indicated as he is moving at the same velocity as the mumps the directed at Va. The angles are proportional to the relative momentum differences of the two frames. Case 2: the same analysis for Vb = 0 and Va moving with all the relative velocity. I will note here that each of the mumps is also a transponder, which makes keeping track of the actual positions of the mumps much easier. Case 3: Both frames moving toward each other. The "o" are Va stones moving down (not shown here) and “|” Va observer. Code: /-------o-| | | |-|-|-| |-0------------/ Va -> ¯ 0 0 0 0 0 0 0 0 0 0 0 0 0 ß \- ------------------------ | | | | | | | | | ---------\<- Vb The"0' ae Vb stones moving up, the Vb observer “|” Here if the Va = Vb the reflection angles will all be the same and if the momenta of each is different then the angles will be proportionally larger or smaller. I am leaving the calculation of the angles as a function of momenta and therefore velocity to the reader. Intuitively there must be some kind of analog to Snell’s law in working this out as there are frictional forces to contend with the calibration will best be performed by experiment and testing. The momentum stone (mump stones) drop technique. I suggested this in a previous post, but thought it useful to include again here. Actually this is almost identical to the mumps tests, but is designed for passenger train, Vn experiments. Dropping a mump from a moving train will indicate the motion of either the train or the embankment, Ve, obviously. The special relativity “considerations” of assuming a moving frame at rest with respect to the Ve by ignorant observers will not rescue the theory. Here, as we all know the Ve does not accelerate and the only way there is any relative velocity between Ve and Vn is if Vn accelerated, which it did, and assuming the Vn at rest will not change the physics of the arrangements. The mump will always indicate momentum in the direction of the moving frame, always, and therefore any observer attempting to cheat by asserting his ignorance of motion will be denied the opportunity and instead we will hand him a mump stone to drop from his window. The observer watching the stone drop in a straight line parallel with a row of vertical rivets on the outside of the train has his attention directed to the ground and seeing the ground pass by is reminded that the stone, while appearing to the untrained and unscientific eye, might think the stones are dropping in a straight line as if Vn were at rest, but now he knows different and he recognizes that the absolute motion of his mumps is a parabola, and he sees the same motion as the stationary observer looking on from the preferred frame of reference Ve. This observer does not see his stone chipped to the rear in the direction of the “non-moving" ground.
