Is a Lorentz transformation allowing an infinite value $c$ still a proper Lorentz transformation?
Is it correct to say that inertial systems are related by Lorentz transformations even if we do not know if the "invariant speed" is finite or infinite? To me, this is incorrect because $c$ ...

Einsteinian principle of relativity in the limit of infinite propagation velocity
We can transform between inertial frames of reference using either the Lorentz transform in special relativity or the Galilean transform in the classical limit.
The Galilean transform gives: $$ x' = x ...

Alternative universes without max speed and with absolute time
I'm not asking of something real but something mathematically possible.
Is it possible to do a math model of an universe (not ours) without max speed and without time dilatations? What would be the ...

Galilean transform as limit of Lorentz one
Galilean transform:
$$\begin{pmatrix} ct' \\x' \end{pmatrix} = \begin{pmatrix} 1 & 0 \\-\beta & 1 \end{pmatrix}\begin{pmatrix} ct \\x \end{pmatrix}$$
Lorentz transform:
$$\begin{pmatrix} ct' \\...

Relativity without constancy of light speed
Using homogeneity of space, isotropy of space and the principle of relativity (without the constancy of light speed), one can derive:
$$x' = \frac{x-vt}{\sqrt{1+\kappa v^2}}$$
$$t' = \frac{t+\kappa vx}...

Replacing $c$ With Infinity
I am confused about replacing $c$ (the speed of light) with $\infty$. I just do not understand how this recovers the non-relativistic physics, mainly, how would this be demonstrated in the Lorentz ...

Can’t we explain well the result of the Michelson–Morley experiment only with the Galilean transformation? [closed]
Can’t we explain well the result of the Michelson–Morley experiment only with the Galilean transformation?
In other words, is the speed of light invariant with respect to inertial frame of references ...

How is Newtonian Mechanics contradictory to Special Relativity at a certain parameter? [duplicate]
How is Newtonian Mechanics contradictory to Special Relativity at a certain parameter and what conditions must be met for Newtonian Mechanics to be a suitable model for describing systems?

Constancy of the speed of light in the hypotenuse of the triangle in the Michelson and Morley experiment [closed]
In Michelson and Morley experiment, Michelson calculated that the total time traveled by light with respect to the stationary observer standing at ether field was $2L/c$.
Here, Michelson followed ...

Special Relativity, 2nd Postulate -- Why? [duplicate]
As a lowly physics undergrad who has been chewing on this 2nd postulate of special relativity for a year or more, I simply can't wrap my head around reasons why it is true or how Einstein might have ...
