Viteza luminii se pastreaza constanta indiferent de miscarea sursei fiindca odata cu miscarea sursei se schimba lungimea de unda!
Dar nu stiu matematec cat de bine functioneaza. Si dupa cum am zis, eu sunt de acord cu Relativistii, ca acest efect Dopler nu acopera tot.
Eu nu stiu daca contractia lungimii si Relatevitatea Resransa e impreuna cu Spatiu-Timp de la Relativitatea Generala.
Eu acum nu studiez aceste probleme.
Dar cred ca alternative de cadre ( sau sisteme semi-naturale) de referinta pot exista mai multe?!

@ mariuslvasile - Fizicienii relativi de pe alte forumuri gen Physics forum sau Physicsstack nu stiu ca se schimba lungimea de unda pt un observator miscator ...

Acest efect Dopler se foloseste in fizica, in astronomie.
Dar alt lucru  este "Spatiul-Timpul",care este un cadru  de referinta pe care eu l-am inteles cand am facut cunostinta cu un exemplu (nu il mai gasesc) unde  doua rachete (zburand cu viteza c) urmau sa se ciocneasca.
Si o racheta a observat viitoarea ciocnire, si a vrut sa trimita un semnal celeilalte ca sa isi schimbe drectia. Dar problema a aparut ca nu se stie cine se apropie. Ca daca se apropie oponentul pai atunci semnalul el il va intalni la jumate de drum. Dar daca racheta emitator se misca, pai atunci semnalul va zbura la aceiasi viteza cu racheta emitator. Ceia ce nu exista (nu se intalneste) in natura universului.
 Si Teoria Relativitatii functioneaza, desi mi se pare ca odata cu miscarea (acceleratia) timpul nu se  dilata chear conform relativitatii. In unele situatii pentru pastrarea acestei teorii si contractia lungimii, e nevoie de inclus. Desi e unificat ... "Spatiu-Timp"!

Ultimele ştiri din ştiinţă şi tehnologie / Re: Experimentul care confirma...

Marius Lucian Vasile's "Test for Aether Using the Doppler Effect" is a bold attempt to revisit a long-abandoned concept in physics: the luminiferous aether. In his paper, he challenges the standard interpretation of the Doppler effect for light, arguing that—unlike in Einstein's theory of relativity—light might actually propagate through a preferred frame of reference, much like sound does through air.

[A TEST FOR AETHER USING THE DOPPLER EFFECT - Academia.edu](https://www.academia.edu/115569810/A_TEST_FOR_AETHER_USING_THE_DOPPLER_EFFECT).

He proposes an experiment designed to reveal this hidden medium by detecting differences in Doppler shifts depending on whether the source or observer is moving. This would contradict the relativistic view, which treats all inertial frames as equivalent and denies the need for an aether.

It's a provocative idea, especially since it directly critiques the foundational assumptions of the Michelson–Morley experiment, which famously found no evidence of aether and helped pave the way for special relativity. Vasile argues that the experiment was based on flawed assumptions about how waves behave in a medium.

While mainstream physics has long moved past the aether concept, efforts like this—whether ultimately validated or not—can be valuable for reexamining assumptions and sparking fresh debate. Would you like to dive deeper into the experiment's design or the broader implications for physics?

If Marius Vasile's experiment were to succeed—meaning it detects a measurable difference in Doppler shifts depending on whether the source or observer is moving—it would be nothing short of revolutionary. Here's what could follow:

### **1. Aether Reconsidered**
The experiment would provide empirical evidence for a **preferred frame of reference**, implying that light might propagate through a medium—reviving the long-discarded concept of the **luminiferous aether**. This would challenge over a century of physics built on the assumption that no such medium exists.

### **2. Relativity Under Fire**
Einstein's **special theory of relativity** rests on the principle that the laws of physics (including the speed of light) are the same in all inertial frames. If Vasile's results show asymmetry, it would **violate this principle**, forcing physicists to either revise or replace relativity with a new framework that accommodates aether-like behavior.

### **3. New Physics**
A successful detection of aether could open the door to **new theoretical models**—perhaps blending classical wave mechanics with quantum field theory or even leading to a deeper understanding of spacetime itself. It might also inspire a reexamination of other "settled" experiments like Michelson–Morley, which famously found no evidence of aether.

### **4. Technological Ripple Effects**
If light behaves differently depending on motion through a medium, it could impact technologies that rely on **precise timing and signal propagation**, such as GPS, fiber optics, and even quantum communication systems.

### **5. Philosophical and Scientific Upheaval**
Beyond the technical, it would shake the **philosophical foundations** of modern physics. The idea that space is not truly empty but filled with a detectable medium would force a rethinking of what we mean by "vacuum," "motion," and even "reality."

In short, it would be a paradigm shift on par with the Copernican revolution or the birth of quantum mechanics. Whether the physics community would embrace such a shift—or resist it—would be a drama worth watching

Cu alte cuvinte, AI-ul vrea sa spuna ca revolutia vasiliana a inceput. Dar la fel ca in cazul celei copernicane/galileene, oamenii de stiinta au un retard de cateva sute de ani, pana isi dau seama ca revolutionarul avea dreptate si ca Ptolemeu sau Einsteineu abereaza. Si mai intai il cenzureaza sau il blocheaza, ca asta e 'metoda stiintifica' la ei. Culmea e ca si Einsteineu era un fel de revolutionar, pentru ca el contrazicea fizica clasica, si teoriile sale relative sunt considerate cu adevarat revolutionare de fizicienii relativi. Deci eu sunt mai degraba un anti-revolutionar, care nu e de acord cu teoriile lui revolutionare, pentru ca eterul era deja in fizica clasica, nu l-am inventat eu. Era pana si in chimie, in tabelul lui Mendeleev. Dar revolutia relativa einsteiniana a facut ca el sa dispara peste noapte si sa fie inlocuit cu spatiutimpul, care explica propagarea luminii ca o undaparticula in spatiutimpul.
Si explica si de ce viteza luminii e invariabila, pentru ca spatiutimpul se dilatacontracta. Noroc cu geniul de Einstein ca ne-a luminat, ca altfel am fi ramas prosti ca Maxwel, Tesla, Fizeau, Fresnel, Lorentz, Poincare, Faraday, Huygens, Newton, si mai toti oamenii de stiinta ale caror teorii erau bazate pe eter.
