Why didn't Michelson and Morley assume or conclude that aether is homogenous and permeate all of space?
In the Michelson-Morley experiment, why didn't they assume or conclude that ether is homogeneous and permeate all of space instead of coming from an unspecified source or direction dubbed the ether ...

Can we think of space as any kind of aether in any way? [duplicate]
I am not asking about the Michelson-Morley experiment in any way. I am specifically asking, if space (including the fields that QFT describes) itself can be thought of as any kind of aether that ...

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 ...

We know there is no aether, so what is being dragged in frame dragging?
I have read this question:
In stellar frame dragging what is the 'frame'?
There are several questions on this site about frame dragging, all of them take the frame that is being dragged as an ...

Do QFT Fields Constitute an Ether? [closed]
As all pervasive, stationary fields, do the QFT fields (various Quark, electron, EM, etc.) constitute the modern equivalent of the traditional ether concept?

How was it determined that the speed of light in vacuum is a constant?
For over a hundred years now we have accepted that the speed of light is the same in all frames of reference. What I'm wondering is - how was this determined?
I'm aware of the Michelson and Morley ...

Stationary aether with respect to Earth? [closed]
Michelson & Morley's experiment implies that either the aether does not exist OR that the Earth is stationary with respect to aether.
Now, one consequence of relativity is that we CAN physically ...

Why I think the Michelson-Morley experiment was originally flawed, and would have failed either way [closed]
I was recently reading about how physicists were heavily relying on the existence of Luminiferous Aether for their physics to work. I read about how the Michelson-Morley experiment attempted to prove ...

Does Michelson Morley experiment assume that the Earth drags aether?
My knowledge is that the purpose of Michelson Morley experiment was to measure the velocity of Earth with respect to aether. It was assumed that the Earth does not "drag" the aether or interfere with ...

The Michelson-Morley experiment as seen by a relativistic observer
I am in a space-craft moving at .99c observing the Michelson-Morley experiment. I am perpendicular to one of the interferometer 'arms'. Due to the apparent 'reality' of Lorentz length contraction I ...

Why must the speed of the aether wind be so small compared to the speed of light?
I was doing some reading on the Michelson-Morley Experiment. One of the principle equations for the equations is this one.
$$\frac { 2w }{ c } \times \frac { 1 }{ 1-\frac { { v }^{ 2 } }{ { c }^{ 2 }...

What does velocity relative to CMB mean? [duplicate]
I've see some velocities such as that of the Sun quoted as "relative to the cosmic microwave background"?
How is this different to measuring velocities relative to that old, discredited idea, the ...

Validity of Maxwell's equations with no aether or relativity?
In From Paradox to Reality: Our Basic Concepts of the Physical World by Fritz Rohrlich page 55 it states that
[...] just doing away with the ether would not have resolved all problems. The problems ...

If the vacuum is not "emptiness" why the speed of the electromagnetic wave is independent of the frame of reference?
If the vacuum were "emptiness" it were easy to accept that there is no "preferred frame of coordinates" and the light velocity is the same in any inertial frame of coordinates.
But the vacuum is an ...

The Movement of Light
I've asked several other questions like this, and I know it's a dumb question but I really can't understand. When light is emitted from a moving source, it still moves straight in that source's frame. ...
