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.

@qjkxbmwvz@lemmy.sdf.org

This was a popular theory at one point: https://en.m.wikipedia.org/wiki/Steady-state_model

There was no expansion in the steady state model while, in this new model, it's easier to explain the perfect black body curve of the CMB.

In addition to CMB being tough to explain, the distant universe is different — for example, quasars are far away/old. You would expect them to be more evenly distributed in a steady-state theory.

The universe I propose is very old, so, it is not uniform.

No, the steady-state model (the Hoyle-era model, not ancient eternal cosmologies) included expansion


Einstein had earlier proposed a static universe, but it turns out that's not stable.

The fact that the universe has different features at different ages is a problem for continuous (non-big-bang) models. Why would e.g. radio sources be more common far away and not nearby? For a continuous/steady-state type theory, far away stuff should be the same (yes it's older, but that doesn't matter, since it's steady state).

Not sure what you mean by self coherence causing "rogue wave" interference which leads to a CMB, and how exponential expansion causes perfect blackbody radiation. But a good exercise would be to play with the numbers to see how you can come up with 2.7K, and see what that suggests about e.g. the density of galaxies in the observable universe.

Also check out more modern "quasi-steady state" theories from the 90s.

Whoops, I was updating my comment while you were responding to it. My edit answered your question ?
Also : "3d interference pattern of gravitational waves would create rogue waves." But, what I mean by "if self coherent" is simply the question : is my model self-coherent.
