Exploring the Concept of an Ether vs. Fabric of Space-Time in LET and SR

In summary, Lorentz ether theory is equivalent to special relativity, but invokes an ether as the cause of length contraction and time dilation with motion through the ether. With it, there are no strange conceptualizations according to each observer's own particular reality for what they observe of other frames, but measurements just work out naturally with a physical shortening of lengths in the direction of motion and a physical slowing of clocks, both on the order of sqrt[1 - (v/c)^2] with motion relative to the ether frame. This is much easier for classical thinkers to conceive since it provides a mechanism by which length contraction and time dilation take place while producing exactly the same predictions as SR. The same simultaneity

I just say that there is no reason to dismiss it as a model, which would have the advantages stated above: its being didactic and its serving to rule out absurd consequences that the math itself does not rule out.
Lorentz Ether Theory has zero advantages over special relativity and many disadvantages. Physicist instructors do not teach Lorentz Ether Theory for exactly the same reason they no longer teach the caloric theory of heat. Both are defunct. The sole reason Lorentz Ether Theory has been revived as of late is because the internet is chock-full of anti-relativity, anti-zionist trolls.


In the context of the ether model, TD, LC and RofS are not simply axioms.
They are incredibly complex and ad hoc axioms. Show me how time dilation, length contraction, and relativity of simultaneity derive from the assumption of an absolute ether frame.


Until you can do so,

Thread closed.

FAQ: Exploring the Concept of an Ether vs. Fabric of Space-Time in LET and SR

What is the difference between an ether and the fabric of space-time?

The concept of an ether refers to a hypothetical medium that was once believed to exist throughout the universe and serve as a medium for the propagation of light. On the other hand, the fabric of space-time is a fundamental concept in both LET (Lorentz Ether Theory) and SR (Special Relativity) that describes the interconnectedness of space and time.

Which theory, LET or SR, is more widely accepted by the scientific community?

Currently, SR is the widely accepted theory for explaining the behavior of light and the fabric of space-time. LET, while still studied and used in certain contexts, has largely been replaced by SR due to its ability to better explain observed phenomena and its consistency with other well-established theories.

How do LET and SR differ in their treatment of the ether?

In LET, the ether is considered to be a stationary medium that serves as a reference frame for the propagation of light. In contrast, SR does not require the existence of an ether and instead considers the fabric of space-time to be the reference frame for all observers.

Can the existence of an ether be experimentally proven?

While there have been attempts to detect the presence of an ether, such as the Michelson-Morley experiment, no conclusive evidence has been found. Furthermore, the predictions of SR have been consistently supported by experiments, making the existence of an ether unnecessary in our current understanding of the universe.

How do LET and SR impact our understanding of the universe?

Both LET and SR have greatly influenced our understanding of the universe and have led to the development of modern physics. These theories have helped us understand the behavior of light, time, and space, and have been used to make accurate predictions in various fields of science and technology.
