Sagittarius A-Star replied to the thread High School What Medium Does Light Travel Through in Space?.Derivation of the EM wave function (a linear, second-order partial differential equation) from Maxwells equations in (3+1) notation... -
Sagittarius A-Star replied to the thread High School What Medium Does Light Travel Through in Space?.Yes. The RHS of the wave function contains a 2nd derivative for ##ct##. In SR, ##t## is multiplied with ##c## as conversion factor. You... -
Sagittarius A-Star replied to the thread High School What Medium Does Light Travel Through in Space?.In 4D-spacetime ##(ct, x, y, z)##, the EM field is a bivector. It has 6 components (3 electric + 3 magnetic), which are projections on... -
Sagittarius A-Star replied to the thread High School What Medium Does Light Travel Through in Space?.That 1) and 2) are equivalent can be seen in Gaussian CGS units. Maxwells equations contain partial derivatives for ##ct## of the... -
Sagittarius A-Star replied to the thread High School What Medium Does Light Travel Through in Space?.In his ether paper, Maxwell proposed to repeat Ole Roemer's measurement of the speed of light two times with an interval of 6 months... -
Sagittarius A-Star replied to the thread High School What Medium Does Light Travel Through in Space?.He regarded them to be strictly valid only in the ether frame. -

Wow.
Whoop.. beat me to it.. -
Sagittarius A-Star replied to the thread High School What Medium Does Light Travel Through in Space?.Yes. Maxwell wrote a paper about the ether. https://sites.pitt.edu/~jdnorton/teaching/Einstein_graduate/pdfs/Maxwell_ether.pdf -
Sagittarius A-Star replied to the thread High School What Medium Does Light Travel Through in Space?.Prior to 1905 it was considered that light waves propagate by vibrations of an ether, which fills space, and that light moves with ##c##... -

For anyone who thinks that I am gaslighting or giving a non-answer I encourage you to actually go through the work and do the relevant... -

That particular rod is that particular length because you picked it. So the value is arbitrary. However, if you keep the same rod and... -
Sagittarius A-Star replied to the thread High School What Medium Does Light Travel Through in Space?.I think this can be an answer to the question "Why does light move in a given timeframe along a certain number of atoms in the old meter... -

Really? You think we don’t grasp the question? No, we understand what they are asking. The problem is just that people don’t like the... -

Or, as I said, vary ##\alpha##, which would actually change ##c## in the sense you mean. But that just leads to the question of why... -
Sagittarius A-Star replied to the thread High School What Medium Does Light Travel Through in Space?.That's because "1 meter" was defined this way. For comparison: The (dimensionless) relativistic speed of sound is ##\beta = v/c \approx...
