comment what is the kinematics of a particle with complex mass?
care to provide a reference to read more about this interpretation?

comment Can antimatter be used as fuel for nuclear reactors?
anna, no one cares about extracting energy from antimatter other than for interstellar propulsion. If we could safely store kilograms, or even tons of the stuff for years, a trip to Alpha-Centauri would take less than a decade. Then, all the inefficiency in creating the antimatter would be just the production cost of interstellar-worthy fuel

comment What is the relationship between vibration of the field and quantum fluctuation?
Fluctuations are usually related to the thermodynamic dissipation of energy in a system via a well-known theorem called en.wikipedia.org/wiki/Fluctuation-dissipation_theorem

comment Superposition in classical Mechanics
the simplest approach to derive the group structure from the differential equation is to expand in power series in terms of the nonlinear coeffs. and find the structure constants for each power

comment Superposition in classical Mechanics
ugh. Some nonlinear differential equations retain a Lie group symmetry of solutions, meaning that $\phi_1$ and $\phi_2$ are solutions, imply that $G(\phi_1, \phi_2)$ will also be a solution

comment Detectability of interstellar messages
our current ways of organizing scientific knowledge make it into very deep, parceled trees with so much repeated work across domains, that doesn't always benefit from the progress that happened in the rest. Science needs more polymaths and generalists desperately

comment How come some people are claiming that the Big Bang never happened?
+1, so it seems they would have done a much more useful job if they would have just focused on arguing their 'Bohmian trajectories are better geodesics in the early universe' point better, rather than assuming everyone would agree with it

comment Is the method of images applicable to gravity?
Any physical systems where such a boundary condition would be imposed would be interesting even if exotic, as the induced mass surface charge at the nearest point between the surface and the positive mass should be predominantly negative energy
