Can someone explain to me what Aether is? And what's the difference between the Higgs field and the aether?
thanks
thanks
When people started to learn that light acted like a wave, they reasoned that there was some medium which the light was a wave perturbation on. This was a fairly reasonable assumption at the time, as all known waves at the time occurred in some medium. They called this medium for electrodynamics the aether. As with sound in air or ocean waves on the water, the relevant speed is the speed with respect to the medium. So they thought that the speed of light (or maxwell's equations in general) were only true in one coordinate system ... the "aether frame" in which the aether is at reast. Experiment later showed that such an aether did not exist (or at the very least had no effect on experiment and therefore was not a subject for science). So the aether is now a defunct topic accept for certain gravity theories that try to add in a dynamic background field that breaks lorentz invariance... but these are not mainstream.Haibara Ai said:Can someone explain to me what Aether is?
As described above, the aether is not related to the Higgs at all.Haibara Ai said:And what's the difference between the Higgs field and the aether?

For example, consider a scalar field coupled to an aether field [itex]u^a[/itex]in the fifth dimension:
[tex]\mathcal{L}_{\phi}= \frac{1}{2} (\partial\phi)^2 -\frac{1}{2} m^2\phi^2-\frac{1}{2\mu^2_\phi}u^a u^b\partial_a\phi\partial_b\phi[/tex]
Aether is a hypothetical substance that was once believed to fill all of space and act as a medium for the propagation of light. It was proposed in the 19th century to explain how light waves could travel through a vacuum.
Aether and the Higgs Field are two different concepts. Aether is a hypothetical substance, while the Higgs Field is a real, measurable field in quantum physics. The Higgs Field is responsible for giving particles their mass, while Aether was proposed as a medium for light propagation.
No, Aether has never been proven to exist. In the late 19th century, experiments were conducted to try and detect the presence of Aether, but they were inconclusive. With the development of modern physics, the concept of Aether was no longer needed to explain the behavior of light and other phenomena.
The concept of Aether was abandoned because it was no longer necessary to explain the behavior of light and other phenomena. With the development of theories such as Einstein's theory of relativity and quantum mechanics, Aether was no longer needed as a medium for light propagation.
No, there are no modern theories that incorporate the concept of Aether. The concept of Aether has been largely replaced by our current understanding of the universe and its fundamental forces. However, some alternative theories and fringe ideas still incorporate Aether as a way to explain certain phenomena.
