You CLEARLY have no idea of how relativity is actually derived and studied, and why it is a pillar of modern physics. Here's a summary: 1. ASSUME that inertial frames are possible, at least locally, and each one behaves as expected in Newtonian mechanics. (All experiments are performed locally, so there's no real need for infinite extents.) Bad ASSUMPTION! Assuming the existence of special frames of reference and calling them inertial frames imply non-inertial frames don’t obey the same laws of physics. This is just absurd. shrug 2. ASSUME that all inertial frames are equivalent, in that the laws of physics are the same in all inertial frames. This is known as the Principle of Relativity. This assumption is too narrow. All laws of physics must apply to all frames of reference including what you call non-inertial ones, or else there is no physics. In this case, the principle of relativity is just a special case to the general law that governs all laws of physics must be the same everywhere and everywhen. shrug 3. Recognize that 1 and 2 imply that the transforms between the coordinates of different inertial frames must form a group. This is required so that the descriptions using different inertial coordinates will be consistent. That is where the metric comes in. To describe that invariant geometry, a metric is unique in the choice of coordinate. Thus, the metric is not invariant. Nor is the coordinate system. The geometry is. The concept of differential geometry placing the metric as equivalent to the geometry is very fvcked up. shrug 4. From the lemma that the transforms form a group, and from basic group theory, deduce that only three groups are admissible transform groups among inertial frames: the Galilei group, the Euclid group (in 4-d), and the Lorentz group. Nonsense! There are an infinite numbers of transforms, discovered by Lorentz, that satisfy the null results of the MMX. None of these satisfy the principle of relativity. In fact, no mathematically consistent transforms satisfy the principle of relativity except the Galilean transform. The Lorentz transform is not mathematically consistent, and it is a paradox itself --- not to mention manifesting the time paradox. shrug 5. Basic observations of the world easily rule out the Euclid group (time is different from space). What observations? Giving the following segment of spacetime, ** dTau^2 = c^2 dt^2 – ds^2 Where ** dTau = local time flow ** dt = remotely observed time flow ** ds^2 = remotely observed space You can trivially write down the following. ** dTau = dt sqrt(1 – (ds/dt)^2 / c^2) Where ** ds/dt = observed speed ** sqrt(1 – (ds/dt)^2 / c^2) = Lagrangian The Lagrangian is the density to the action of minimizing any event time. Thus, with that Lagrangian, you can derive the relativistic momentum and (E = M c^2). shrug So, where mathematically the mathematics of SR is supporting your statement? shrug 6. Observations of optical phenomena and of particle experiments rule out the Galilei group. Yes, we know. Both the combination of electromagnetism and the MMX rule that out. shrug 7. Literally zillions of experiments confirm the validity of the Lorentz group as the transform group among (locally) inertial frames. Nonsense! These same so-called experimental verifications also support the infinite other transforms satisfying the null results of the MMX where the principle of relativity is ruled out in favor of an absolute frame of reference. shrug 8. The Lorentz group is the essence of Special Relativity. Namely the Lorentz transform, yes. shrug 9. More importantly, no experiment or observations are significantly inconsistent with SR, within its domain. No experiments have supported mutual time dilation. SR predicts universally incoherent interference patterns which is falsified by any interferometers and the same experiment that gave rise to SR. shrug Yes, this is following the scientific method. Only in your make believe world. shrug Note that Einstein's original second postulate is not necessary -- experimental results are a better approach. Note also that the ACTUAL assumptions, 1 and 2, are quite solid, and are much more fundamental than the nonsense you spouted above. This reads like a scripture. shrug |

Except the Galilean transform that models light as classical particles, all other infinite numbers of transforms that satisfy the null results of the MMX invalidates the principle of relativity. The Lorentz transform was fudged out of Larmor’s original transformation. The Lorentz transform is not mathematically consistent. Thus, assuming the validity in the principle of relativity is downright stupid. shrug |

'Ether and the Theory of Relativity - Albert Einstein' http://www.tu-harburg.de/rzt/rzt/it/Ether.html "the state of the [ether] is at every place determined by connections with the matter and the state of the ether in neighbouring places, ... disregarding the causes which condition its state." The state of the aether as determined by its connections with the matter and the state of the ether in neighboring places is the state of displacement of the aether. The state of the aether connected to and neighboring the MMX is in the same state, or almost the same state, throughout the Earth's rotation about its axis and orbit of the Sun. Watch the following video starting at 0:45 to see a visual representation of the state of the aether. What is referred to as a twist in spacetime is the state of displacement of the aether. What is referred to as frame-dragging is the state of displacement of the aether. http://www.youtube.com/watch?v=s9ITt44-EHE The analogy is putting a mesh bag full of marbles into a superfluid and spinning the bag of marbles. If you were unable to determine if the superfluid consists of particles or not you would still be able to detect the state of displacement of the superfluid. The superfluid connected to and neighboring the mesh bag of marbles is in the same state throughout the rotation of the bag in the superfluid. The aether connected to and neighboring the Earth is in the same state, or almost the same state, throughout the Earth's rotation about its axis and orbit of the Sun. The state of which as determined by its connections with the Earth and the state of the aether in neighboring places is the state of displacement of the aether. |

Koobee Wublee wrote: This does not prove anything. The Voigt transform also predicts the same thing, and yet the Voigt transform says the Aether must exist. Your experimental result satisfies just about an infinite number of the mathematical model dealing with how observations are related as observed by two frames of reference. Why do you cherry-pick the Lorentz transform, which is the only one that satisfies the principle of relative through some mathematical fudging, to be the only one to do so? This should not be too much to ask when dealing with scientific method in mind. shrug Well, you can certainly claim the sole validity in the Lorentz transform, but you must provide irrefutable experimental results to justify the cherry-picking. Koobee Wublee repeatedly makes so many errors, Where? Making things up to hide your faith again, Tom? shrug acts so childish, and is so abusive, that I rarely if ever read his nonsense or respond to him. Wait a second. You started this shrugging. You have repeatedly asked anyone who did not agree with you to read up on books as if they are so much uneducated. You have talked down on others and calling them stupid. All are beneath you according to you. Before you calling must posts abusive, you’d better read your posts again and picture yourself as the ones you were responding to. shrug There are an infinite numbers of mathematical models that satisfy the null results of the MMX not solely in the Lorentz transform. However, other than the Galilean transform that models light as classical particles, the Lorentz transform is the only one that satisfies the principle of relativity. So, Koobee Wublee has repeatedly asked you what experiments have settle the Lorentz transform apart from the infinite others that do not satisfy the principle of relativity? There are actually none. So, the assumption that nature obeys the principle of relativity had no and still does not have any justifications --- what’s so ever. Thus, the ones who embrace a theory based on assumptions without later justifications are just so f______ s_____ (you fill in the blanks). shrug The Lorentz transform is derived from Larmor’s transform where one of the two observers must be the absolute frame of reference. The mathematical models of spacetime of both are exactly the same. How do you know what spacetime you are referring to since one does not satisfy the principle of relativity, but the other one does? How can you build an entire theory on something you have no idea of identifying at its foundation? Thus, the ones who embrace a theory without its foundation thoroughly identified are just so f______ s_____ (again you fill in the blanks). shrug These questions are not abusive but down to the point. Since you have answered more abusive posts before, you are just choosing to ignore the ones you cannot answer in which they would SHAKE the very foundation of your faith in SR and GR. After all, you are sort of a scientist, and you just cannot afford not to read Koobee Wublee’s posts. So, go ahead and choke on what Koobee Wublee has to write, but wait for the rare opportunity where Koobee Wublee would slip out and spill your gut on that. shrug All laws of physics must apply to all frames of reference including what you call non-inertial ones, or else there is no physics. But the quote above is one of his rare correct statements; true to form, he stated it poorly and in the wrong context. Here is a better statement of essentially the same concept: The laws of physics are independent of coordinates. There are subtle differences. For instance, bringing in coordinate systems implies observers. So, when you say the laws of physics are independent of coordinates, you are saying the laws of physics must be observed to be the same for all observers. Thus, for something not observable, your statement does no longer encompass. One example is the mutual time dilation under SR. Koobee Wublee’s statement is more intrinsic in nature. It says the laws of physics must be the same everywhere and everywhen regardless of events can be observed or not. shrug Indeed, this is the basis of General Relativity, where it goes by the (somewhat misleading) name of "general covariance". This is just wrong. General relativity is based on the invariance in the metrics not in the invariance in the geometry. Since mathematically the metric cannot represent reality if the choice of coordinate system is not yet established, GR is based on a misconception in geometry. The geometry must be invariant regardless what coordinate system one chooses to employ. For each choice of coordinate system describing the same invariant geometry, there is a unique metric associated with that particle set of coordinate system in describing that invariant geometry. This should be basic down in the fourth or fifth grade level of mathematical concepts. It is definitely very “surprising” that the physicists would start and continue to make that same mistake. Thus, the ones who embrace a theory that is erroneous from the basic concept in grade school geometry can only be described as f______ s_____ (once again you fill in the blanks). shrug It is much more complicated than SR and its inertial frames, but with tensor analysis is tractable. GR is not much more complicated than SR. It is merely more complex in the mechanics of mathematical manipulations. Once you have understood the motivation and how the Christoffel symbols are derived, the rest is a piece of cake. Self-styled physicists have allowed themselves in indulging in mysticism. The origin of the Christoffel symbols have since shrouded in mystery and mysticism. It is no wonder that they have promoted GR as the most complex piece of theory ever conceived by man through the branch of mathematical study called tensor calculus. Well, in reality, there is no such thing as tensor calculus. It is still following the same and exact rules of calculus established by Leibniz since the time of Newton almost 400 years ago. The whole thing about GR is way too overblown, and guess what the motivation is. Thinking along the same line as ancient priests attempting to keep their elite status quo from peasants would not be too far off. shrug |
