giacomo , in Gravity field scaling?

This seems interesting.

Gravity fields are just potentials, as gravity requires at least two bodies, right?

If the universe only contained one body of irrelevant mass, without anything else to interact with it would just sit there. Further there would be no time, as there would be no change.

If Earth’s mass were to double, all gravitational relations, including potentials, would also increased but it’s not exactly double as the equation should also account for the other body or bodies masses.

I’m not a scientist, I’m just smoking weed on a sunday. I’m hoping some actual smart people can explain this like I’m high.

If Earth’s mass were to double, all gravitational relations, including potentials, would also increased but it’s not exactly double as the equation should also account for the other body or bodies masses.

I think the simple Newtonian version is: Break down each gravitational relation (A and B pull on each other) in it’s components: A pulls on B, and B pulls on A. If you double the mass of A, this has two effects:

  • A pulls on B twice as much
  • B pulls on A the same, but needs twice as much force to achieve the same acceleration (a = F / m)
count_of_monte_carlo , in New physical cosmological model : is it coherent ?

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.

count_of_monte_carlo ,

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.

@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.

count_of_monte_carlo ,

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.

A_A OP ,
@A_A@lemmy.ca avatar

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.

@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.

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 ?

@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.

qjkxbmwvz ,

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.

@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.

Anticorp , in if something happened to the black hole at the center of our galaxy, could we know about that problem before it affected us?

Nothing will happen to the black hole, except for its continued growth. At least not anything on time scales that are meaningful for humanity. We’ll be long gone before any observable changes happens to any black holes.

jesterraiin , in What if the measurement device in the double slit experiment were a light year away?
@jesterraiin@lemmy.world avatar

If the measurement device were a light year away and were precise enough to “zoom in” and see which slit the electrons went through, what would happen on the final screen?

That level of precision implies technological advancement, that would result with far better equipment to perform the test and measure the results, providing they would be still needed.

I know it sounds like an attempt to brush the question off, but it’s Spherical Cow and/or Newton’s Flaming Laser Sword territory. 😉

Brokkr ,

The results of the double slit experiment and the uncertainty principle will not change with our level of technology. They are fundamental laws of nature.

The quality of the camera to observe the result of the double slit experiment (meaning the pattern on the wall) has no effect on the results.

jesterraiin , (edited )
@jesterraiin@lemmy.world avatar

I disagree.

The hardware, software, money involved and other variables required to conduct an experiment from a lightyear away definitely elevate the project to different level on Kardashev’s scale.

WarmSoda , in What would happen if we mixed nuclear waste into gasoline

What if we, come on guys I’m serious, what if we mixed it with bourbon?

m0darn OP ,

2.5 million barrels per year x 200 liters per barrel = 500 million liters

So about 1000 times smaller volume than gasoline. So 1000 gains of sand worth per liter.

Something about its nuclear structure. There just isn’t a stable structure its protons and neutrons can form.

Razorwire666 , in After seeing the photo of a hammerhead skull today: Can someone tell me what evolutionary pressure caused it? What is the advantage of the hammerhead skull shape?

I believe it’s to spread out the electical sensors they use to detect prey in the sand/mud on the ocean floor.

I’ve wondered why no one seems to be seriously putting effort into a genealogical ship. I’d be okay with being the first generation; I can’t possibly be the only one.

danhab99 OP ,

I guess there’s a place to be conserned that eventually a society might emerge within the genealogical ship that might cause them to loose their allegiance to the rest of humanity and go their seperate way. We saw this when european colonists came to the new world, they didn’t stay loyal to their home governements because of the difficulty to communicate across the ocean and the difficulty the home government would experience projecting their authority. Communication would be just as difficult with a genealogical ship and they might leave us forever, like we’ll never see any benefits from the genealogical ship.

And when you think about it that would make the most sense, because even when the final decendants of the genealogical ship find a new home world they’ll never come back to earth, their will be no travel. That world would become a different world for people who might not even consider themselves as human.

Conclusion: there’s no way to space travel unless a person can travel between worlds and still have enough of their lifespans ahead of themselves to do stuff to contribute to the wider galactic human soceity. Unless you want to live in the cowboy bebop world where the government is too weak to do anything so they have to hire bounty hunters to suppress criminal organizations competing governments, and you don’t know who has your better intrest and who’s going to protect you from who, be my guest, fracture human soceity before we’re truly ready to go out into space. It sure worked out well 100 years ago.

FlowVoid ,

Because nobody is interested in buying you an all-expenses-paid trip to space.

Where would you go, and what could one ship’s crew do there?
