What exactly is weird about waves propagating without a medium? What does it violate? [closed]
I can not seem to grasp, why exactly does light travelling through space without the need of any medium was baffling for the scientists of 1800's.

The medium of electromagnetic waves [closed]
I'm just wondering if anyone else has ever pondered the question: what medium do electromagnetic waves travel through? and like me remained unsatisfied with the explanation that they are 'non-...

Can transverse waves be both mechanical and non-mechanical?
Transverse waves need a medium for particles to propagate perpendicular to the wave right? Then how can transverse waves be non mechanical which do not require any medium?

Why was there a need to create the ether when we knew the existance of magnetic fields? [closed]
I have been reading about 19th century physics and how it was believed that electromagnetic waves needed a medium in which they traveled at c, my question is why was it thought that the ether needed ...

Doesn't Lorentz transformation disprove aether?
I am struggling to understand the reason behind why lorentz still believe in the aether theory after developing his transformation.
The aether frame is the frame by which all velocities should be ...

Is there any difference between ether and EM field?
I want to ask about a specific aspect; do we move relative to the EM field? Can we design an experiment similar to the Michaelson Morley experiment to measure our velocity relative to the EM field? If ...

If there is no ether what is the medium in which waves, pulses travel around the universe? [duplicate]
What is aether (ether) actually? Is it space-time fabric curve or is it anti-matter? If not this what is it then, does it exist? Why is the concept disregarded after Einstein's theory of Relativity?
...

What is the phemonemon behind electromagnetic waves being able to propagate in the vacuum?
I'm recently picking up interest about some aspects of physics, I never really studied physics apart from some basics and I'm having trouble finding a good course explaining the theorical approach ...

Why light was said to be faster than electromagnetic changes in ether?
According to Wikipedia on the historical development of the Lorentz ether theory:
... Contrary to Clausius, who accepted that the electrons operate by actions at a distance, the electromagnetic field ...

Maxwell Equations in Earth frame
Considering that the luminiferous ether exists around earth, if all electrodynamics experiments are done in earth frame how do we know that the speed of light $c$ we calculated from it is not $c$ with ...

Why Maxwell thought that aether was needed?
The present knowledge of electromagnetism says that a time-varying electric field generates a time-varying magnetic field and vice versa; this would result in an electromagnetic wave. Maxwell was one ...

What is a medium?
I was reading this and in there it states that
The weakness of the wave theory was that light waves, like sound waves, would need a medium for transmission. The existence of the hypothetical ...

What does a Galilean transformation of Maxwell's equations look like?
In the 1860's Maxwell formulated what are now called Maxwell's equation, and he found that they lead to a remarkable conclusion: the existence of electromagnetic waves that propagate at a speed $c$, ...

How does the existence of aether allow for the Galilean transformation?
I was reading this and it said that the aether was proposed as a fix to accommodate the Galilean transform because the Laws of Electromagnetism did not remain constant under the Galilean transform. ...
