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.

Agreed, this is the most on topic post we’ve had for a while.
We both think my post was on topic, unfortunately, ShowerThoughts moderators deleted it !
Generally, conservation of energy applies in a closed system, so [it] wouldn’t apply at the creation of the system.
Plus we can’t (yet) be sure what caused the Big Bang if it happened.
Nice 😊 !
I’ve always liked the idea that matter, space and time are the way we observe the interactions of fields. So gravity waves make an interesting idea as to how part of it might work
Now we need a physicist and a mathematician, which obviously, I am not.
You might be interested in Dirac large numbers hypothesis, where the mass of the universe depends on the age of the universe. That kind of [ideas] would be a hint for matter being continually created.
Thanks, I will read into it.

I might be missing something, but how would this new model reproduce the CMB? The cosmic microwave background is a black body spectrum with an extremely uniform temperature in all directions. The localized fluctuations in temperature are only a very small shift to the average.
By the integration over an exponentially expanding universe of the fluke electromagnetic radiation created locally. Maybe matter is created as neutrons that decays into hydrogen atoms which would then radiate something.
Thanks for responding!
Photons emitted from radioactive decays have specific wavelengths. Even with Doppler broadening blurring it out, I don’t see how integrating over all decays at all distances would produce a black body spectrum.
The black body spectrum shape is actually really hard to produce through another mechanism. In fact, before the discovery of quantum mechanics attempts to calculate a black body spectrum with classical mechanics failed at short wavelengths. This problem was called the ultraviolet catastrophe.
Maybe this is what would falsify my proposal… unless maybe that fluke local radiation could start at the maximum energy of the black body curve ? I will try to look into this.
Interesting idea. And the so-called “Dark Energy” also results from the rogue waves or perhaps another process?
There is no need for dark energy since this is at net zero energy.
N.B. : this is a continuation of this post :
https://lemmy.ca/post/3510924This 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.
Oh nice, thanks for the link. Not usually the kind of thing I expect in a shower thoughts community
Since the post was erased I don’t know what link it was… maybe it’s the one about the Penrose process ?
(energy extraction from a rotating black hole)I’m trying to understand what you’re proposing here, so I have a few questions.
3d interference pattern of gravitational waves would create rogue waves at specific points in SpaceTime that would create matter and the CMB.
What is the source of these gravitational waves? Binary black hole mergers, neutron star mergers, something else?
How would rogue gravitational waves create matter?
How would rogue gravitational waves produce the cosmic microwave background?
Creation of matter and gravity fields, at net zero energy would increase the expansion of the universe.
What do you mean by “net zero energy”? Is it that this process of creating matter and gravitational waves would also conserve energy somehow? How would this increase the expansion of the universe?
The perfect black body curve of the CMB would result from the exponential expansion of the universe.
How does the exponential expansion of the universe produce the black body CMB? In the standard big bang model, photons are emitted during the recombination epoch and have a very uniform black body temperature since the matter that emitted them had been in thermal equilibrium prior to expansion. These photons are then extremely redshifted by the expansion of the universe.
What is the source of these gravitational waves?
in my post there is a link for a powerful source of these waves but any source is good enough.
How would rogue gravitational waves create matter?
Here I use an analogy with the waves in the ocean that were discovered to create very strong unexpected phenomenas. When a field is strong enough it can create matter. So, it would be something similar to Hawking radiation or creation of electron positron pairs from gamma rays.
What do you mean by “net zero energy”?
I was most impressed by a single fact of physics that all energy in ordinary matter is equal to the negative potential gravitational energy of that matter.
How would this [creation of matter and gravitational fields] increase the expansion of the universe?
I read somewhere, maybe quantum gravity theories, where one creates the other, so I would have to search it again, unless someone here can help me.
(…) black body CMB?
Please notice that inside another comment in this post I have addressed that question.
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 was most impressed by a single fact of physics that all energy in ordinary matter is equal to the negative potential gravitational energy of that matter.
I’m not sure what you mean by this, could you point me to a reference where you saw this statement?
I will come back here to answer your questions one at a time … )
Great! I look forward to it.
I need some rest now. I will try to be back some other time.
