As the title asks, what is the average mass of each kind of cloud? Ignoring things like overcast days, and only considering clouds large enough to identify. Or maybe rather than “average” it’d be better to say “what is the mass of an archiypical cloud of each type?” Eg an archiypical cumulus, cirrus, cumulonimbus, etc.
I believe in this community you have to write the word “rule” in the title, like so : Banana? Banana rules !

I’ve been a comic reader on and off over the years but I wanted to really sink my teeth into it lately. I’ve read a few of the more popular stories. Most notably, Extremis, Hyper Velocity, and The End. What stories do you recommend to get into Iron Man more?
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.
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....
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.
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.
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.
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.
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.
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.
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.
With 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 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.
I’ve been doing a bit of searching for theories on the origin of baryon matter (including antimatter of course) and some seem to hint at quantum particles spawning from the fabric of space (but doesn’t seem to theorize on how this happened) but not many focus on hypothesizing how all forms of baryon matter ether: was the...
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.
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 😄 !

I had to rebuild completely my post (questions and answer) from other users also, because some moderator, at “ShowerThoughts”, deleted the post while it was in progress.
Observations from the James Webb Space Telescope have revealed a surprising number of young galaxies containing massive black holes at their centers, churning up the gas within only a few hundred million years after the Big Bang. Spectroscopic data indicates that these “hidden little monsters” harbor black holes weighing...
Cosmic microwave background (CMB) is very smooth ; if there was black holes in there I guess we would see (huge) unevenness.
Hummm, or at least, that stupid LCDM would lead to such an expectation. … that model also put CMB at : 400 000 to 500 000 years after the BBang.
and most distant visible galaxies (and black holes) at : 330 000 000 years after BB.
if we go by this number we have a few hundred million years to produce such big things out of something very smooth.
if we used a different model we could have much more time.
The title of that paper is :
“Supermassive Primordial Black Holes From Inflation”
I have read about inflation since many years and it is viewed increasingly as impossible and falsified.
I don’t work in this field. For me this is just a hobby. Are you a physicist ?
Under this very article you provided you can read, at criticism :
At a conference in 2015, Penrose said :
“inflation isn’t falsifiable, it’s falsified. … BICEP did a wonderful service by bringing all the Inflation-ists out of their shell, and giving them a black eye.” (…) Penrose’s shocking conclusion, though, was that obtaining a flat universe without inflation is much more likely than with inflation – “by a factor of 10 to the googol power!”
Please read about this guy :
Roger Penrose (…) mathematician, mathematical physicist, philosopher of science and Nobel Laureate in Physics.
I read much more than the average person about it and my experience & education allows me to know how scientific research works. The fact is, not only inflation but Lambda CDM is dead.
I think what’s also great with Penrose is that he doesn’t care about money or politics, which are major factors guiding what other physicists will say.
He already proved himself and doesn’t need to argue about pity things. He can even allow himself to make some jokes about 10^(10^100) or talk seriously about it… I wouldn’t know.
Finally, if I add the immense chance of talking to him this wouldn’t be my preferred topic.
So I will read through some of this and try to come back with something worthwhile to say.
Update : I read some more and most of that is just out of my reach. The only paragraph I kind of understand somewhat is this :
(…) conformal cyclic cosmology (CCC) theory.[67] In this theory, Penrose postulates that at the end of the universe all matter is eventually contained within black holes which subsequently evaporate via Hawking radiation. At this point, everything contained within the universe consists of photons which “experience” neither time nor space. There is essentially no difference between an infinitely large universe consisting only of photons and an infinitely small universe consisting only of photons. Therefore, a singularity for a Big Bang and an infinitely expanded universe are equivalent. [68]
I read through these and try to understand them but mostly I don’t like those theories, because (in part) more and more there are disparities between them and observations.
