Invariant means that the speed of light in vacuum

No, invariant means that the speed of light does not vary with the speed
of the emitter.
Like most everything you are wrong about, this is a simple look up,
crackpot.
invariant meaning in physics:
In physics, "invariant" means a quantity that does not change under
a specific transformation, like a change in reference frame or a
rotation. Essentially, it's something that remains constant despite
how you describe it or how the system is viewed.
There is no such thing as the inertial reference frame in the entire
universe.
inertial reference frame meaning in physics:
In physics, an inertial frame of reference (also called a Galilean
frame of reference) is a frame of reference where Newton's first law
of motion (inertia) holds true. This means that objects within that
frame will remain at rest or move at a constant velocity unless acted
upon by an external force.
