General Relativity: Definition of Locally Inertial Frame

Can the Lorentz transformations be derived this way?

What's the actual path of the planets?

How to prove that both $\mu_0$ and $\epsilon_0$ don't depend on any frame of references?

How can we conclude from Maxwell's wave equation that the speed of light is the same regardless of the state of motion of the observers?

Why don't these conversions of time between reference frames seem consistent?

Relativity: correct way expressing energy?

How does the Equivalence principle explain "what goes up must come down"?

How exactly are Lorentz transformations rotations?

Why can't the constancy of the speed of light be deduced from classical physics?
