The following mechanism, by continually creating matter in the universe, if self coherent, would solve many unsolved physical problems : this cosmology would do without a big bang.
3d interference pattern of gravitational waves would create rogue waves at specific points in SpaceTime that would create matter and the CMB.
Creation of matter and gravity fields, at net zero energy would increase the expansion of the universe.
The perfect black body curve of the CMB would result from the exponential expansion of the universe.
The gravitational wave background you linked is extremely weak, it took decades of measurements of pulsar timing and complex signal processing to even see hints of it. In general, the gravitational force is so much weaker than the other forces that it can be ignored except on very large scales. So I’m not seeing how a rogue gravitational wave would produce sufficient energy density for creating matter via pair production or some other mechanism. You would need extremely large amplitude gravitational waves, which would require some even more energetic mechanism for generating them. Maybe this is something you can work into your model?
I’m not sure what you mean by this, could you point me to a reference where you saw this statement?
Great! I look forward to it.
I need some rest now. I will try to be back some other time.
