To be more correct, that "signal" lasts for 200 ms (four time-divisions a 
0.05sec/division). And it started by a 60 Hz ending at 200 Hz. There is 
nothing above the 200, I did the fourier.

No, not paper, I want to see the model and the files from the proper MODEL 
simulation. Without it, you just have a theory, not a model. Let us see 
the inputs to his model, constants, parametres, governing equations, 
domains, constraints, initial conditions, boundaries etc etc. Then show me 
that the output from that MODEL is anything which would resemble a black 
hole, let alone two black holes.

You don't know, but assume. It rather looks like E-Matrix, not black holes.

Hence you admit, that the "real simulation" presented by those in charge 
for the machinery, is totally wrong. Did you see those "black holes" 
diameters when compared to the surrounding star systems?

This is impossible. No significant energy is been outputted before the 
actually merging collision. Orbiting masses are not loosing energy.

Finally we agree. Thanks.
