No physical mechanisms predefines future events (or is there one ?).

So, I could state that the future does not exist yet and the past as ceased to exist.

in that statement I have a problem with the definition of existence. Does the definition of existence exist itself ? This is (is it ?) more a problem of terminology than philosophy or physics.

Anthropologically speaking this is the best answer. Our brain needs a certain span of time to establish perceived reality.

Humanity is so stupid when it comes to “territory” and we are not the only species that acts like beasts about it.

At sea level air is about 1.25 kg/m³, so for one cubic kilometer cloud that is :
1 250 000 tons.

I put your result into table to show a problem at 51 km and above… since density decreases monotically with altitude.

mass (tons)	altitude (km)
1 250 000	0
364 000	11
88 000	20
860	51
64	71

Hey @Jeredin

This one, @FlowVoid, has the correct answer…

So, don’t believe in the crackpot idea that it would be exponential

A_A , 10 months ago (edited 10 months ago)

I did make I have made many mistakes, much worse than this one and on many occasions. I would say : don’t be so hard on yourself since it’s important to forgive ourselves.

I do believe the following correction should be made again to your text though :

Gravity is an [edit: inverse squared] function, so it gets weaker at an exponential a squared rate as you move away from the source.

A_A OP , 10 months ago (edited 10 months ago)

@Jeredin

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.

@qjkxbmwvz

This was a popular theory at one point: 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.

@Aurenkin

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)

A_A OP , 10 months ago

@PinkOwls

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.

A_A OP , 10 months ago (edited 10 months ago)

@FelipeFelop

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.

A_A OP , 10 months ago

@count_of_monte_carlo

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.

A_A OP , 10 months ago (edited 10 months ago)

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.

A_A OP , 10 months ago (edited 10 months ago)

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.

A_A OP , 10 months ago

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.

A_A OP , 10 months ago

I need some rest now. I will try to be back some other time.

A_A OP , 10 months ago

There is already a link in my post for one big source of gravitational waves

A_A OP , 10 months ago

Those mostly create magnetic and electomagnetic radiation. Some are also magnetars

A_A OP , 10 months ago

The original Big Bang also violates conservation of energy.
For the moment this is just a shower thought. More work would have to be done along these lines.

A_A OP , 10 months ago

I often think about this in the shower

P.S. : Also, i just read the rules and I believe I follow them

A_A OP , 10 months ago

Those black holes allow the Penrose process which is somewhat similar to what I am talking about here.

A_A , 10 months ago

Wanted to see this since a long time ! Do you have a source ? Please ?
Unless maybe you are talking about this :
Zero-point energy

A_A , 10 months ago

You are talking about Penrose now and it is a nice coincidence that I wrote about him yesterday here :

A_A , 10 months ago

Yes we had a nice exchange five or six days ago in your post :
Beyond the Darkness - Dark Matter: A Baseless Hypothesis?
I am not a physicist and I don’t work in this field. I just read since many years and I made my mind about what was going to be successful and what was not.

My best prediction so far was that JWST was going to see the same type of galaxies very far away as those in the local universe. (at least partially verified) I made that same prediction when Hubble telescope was put into orbit. Back then physicist started doubting their theories.

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. Because of this I am scanning all I read for clues for a mechanism where matter could be created from gravitational field …something like Hawking radiation. For the same reason I am also looking for evidence that the universe could stand for a much longer time since the CMB. This would be the case for a universe that would be exponentially expanding. Suppose the accelerating rate of expansion double each 10 billion years or so. Then, if you go in the past every 10 billion years the rate of expansion is smaller and smaller exponentially decreasing and the universe is extremely old.

I have so many more ideas but I don’t want to make a wall of text.

A_A , 10 months ago

if we find a mechanism that continually creates matter in the universe we don’t need a big bang. Creation of matter and gravity fields, (net zero) could somehow increase the expansion of the universe. 3d interference pattern of gravitational waves would create rogue waves at specific points in SpaceTime that would create matter and the CMB.
Oops ! I just defined a new cosmological model 😄 !
