Default Emdrive might change the law of inertia (for the Earth too!)

For the fact that action reaction violation need the change of the first law of newtonian inertia

It conveniently assumes that it's possible to change the charges on such
a time-scale without the resulting magnetic fields totally negating the

A full analysis will show either that there's no net force, or that the
change in momentum is matched by the momentum carried off as a result of
a net radiation of electromagnetic waves in the opposite direction.

Oh, and the fact that this thing will inevitably radiate electromagnetic
waves means that it requires a constant input of power.


If one assumes that the principle of action and reaction can be overcome in electrodynamics it must accept the consequences also on the law of inertia.
And the change of the law of inertia is a great opportunity to shorten the time of interstellar travel


I don't know why one would make such an assumption, given the lack of
experimental evidence to support it.

It should also be noted that any anisotropic radiator experiences a net
force, completely in accordance with current theory. To be compelling,
an experiment has to show a force in excess of that that would be
produced by radiation for a given power input.


The essence of the problem is that in the electrodynamic principle of action and reaction does not make sense to theoretical level. As it says W. Moretti in

"Now in electrodynamics if the two bodies are charged, because of the delay effect you mention due to the mediation of the electromagnetic field, the third principle as I have set out above is not the case. The EM field can not 'be considered a body for various reasons (not even in the continuous theory mainly because 'does not define a field of speed' ...) for which the third principle can not 'even be formulated for the system charges + EM field. “

Unfortunately many physical books ignore this thing
