there's a lot of debate in the scientific community and in the general public over the definition of the word "planet," with some saying that only the 8 most gravitationally dominant objects orbiting the sun should be considered planets, and others saying that any gravitationally rounded object in space, even moons, should be classified as planets, and still others who insist that all the scientists are wrong and that the planets should be the big 8 plus pluto because nostalgia or whatever
i propose a simple alternative that will make everyone happy: defining planet as a grain size on the wentworth scale (the scale used by geologists to describe the sizes of sediment grains), as a category above "boulder"
Tumblr media
in this system, a planet would be any grain larger than, say, 500000000 mm. earth would be a fine planet, jupiter would be a very coarse planet, neptune would be a coarse planet, exoplanets between earth and neptune in size would be medium planets, and our beloved little pluto would be a very fine planet <3

Planet Diameter Equation
The Paper tests and analyzes The Planet Diameter Equation (my 4th equation)
The Equation defines each planet diameter and proves it's created as a function in the planet rotation period and velocity – let's introduce the equation in following-
Planet Diameter Equation (v1/v2)= (s/r)= I
v = Planet Velocity                                                          
r = Planet Diameter
s= Planet Rotation Periods Number In Its Orbital Period
I= Planet Orbital Inclination        (example, 1.8 degrees be produced as a rate 1.8)
v2, s, r and I are belonged to one planet and v1 is belonged to another planet
The planet (v1) is defined by test the minimum error 
Earth Equation uses Neptune velocity
Mars Equation uses Pluto velocity
Jupiter Equation uses the Earth moon velocity
Saturn Equation uses Mars velocity
Uranus Equation uses Neptune velocity (As Earth)
Neptune Equation uses Saturn velocity
Pluto Equation uses the Earth moon velocity (As Jupiter)
(The Equation works from The Earth To Pluto) (the discussion explains the reason)
Example
Neptune Equation (89143 /49528) = 9.7/ 5.4 =1.8               
89143                   = Neptune rotation periods number in Neptune orbital period
49528 km   = Neptune diameter
9.7 km/s      = Saturn velocity
5.4 km/s      = Neptune velocity
59800 days = Neptune orbital period (and Neptune rotation period =16.1 hours)
1.8 degrees = Neptune Orbital Inclination
Planet Diameter Equation Importance
The Planet Diameter Equation produces many useful results but the major one is (The Change In The Solar System Classical Vision)- shortly- the equation forces use to accept a new vision about the solar system creation and motion- let's summarize this vision ideas in following…
(1)
The Planet Creation Data Is Defined Based On Exact Equations- this is a simple idea
The airplane manufacturer needs exact equations to define this airplane length, width, weight and all dimensions otherwise this airplane can't fly safely
The planet creation data is similar to that- the planet diameter, mass, density and all creation data should be defined based on exact equations otherwise this planet can't move safely- clearly – the idea is a simple one –
BUT
No one believes in it- Why?
Because- the physics Book tells- the planet is created by random process and the planet data are effected by historical events- let's use an example-
Jupiter diameter = 142984 km because it's created by random process and effected by historical factors and be = 142984 km by chance and if this diameter be 170000 km that has no effect on Jupiter motion theory- for that – Jupiter motion theory doesn't know why Jupiter diameter is =142984 km
This analysis is a crucial one- because- it causes to remove the source of knowledge 
By that- the planets data is available for everyone but no one can use it-No one knows Why Mars diameter = 6792 km or why its rotation period is 24.6 hours- why Venus orbital inclination =3.4 degrees – the data is available but useless because every one believes by heart that – the data is created by random and no geometrical reason was found behind its creation.
That shows the massive importance of My Planet Diameter Equation- 
The equation tells – The planet diameter is created based on a geometrical rule and by an exact equation-
Means- Jupiter original diameter is created as (142984 km) by a geometrical reason and the diameter isn't changed by any historical effect- and still be 142984 km without change. 
What did I do to find this equation?
I have put the planets diameters in front of me and tried to find one rule controls all of them and found this equation-
Means- I used the data in place to neglect it for the idea tells (The Data Is Created By Random Process Without Any Geometrical Reason And They Are Useless)
Also this is noticeable- the book tells (The Data Is Created By Random) but no one tried to prove or disprove this idea-
The idea is more deep- because it tells– The Matter Dimensions Are Defined Based On Geometrical Reasons  
It's not only for planets diameters- it's the matter dimensions generally are produced by geometrical rules – that tells us – the planet diameter equation can help to answer the question (what's the matter?) or (how is the matter created?)
(2)
Now we realized, the planet diameter is created based on a geometrical rule – but the classical vision has many other wrong ideas- again- the planet diameter equation can help here also –
The next idea to examine tells (The Matter Is Motionless By Nature)  
This idea creates the mass gravity concept- and – the mass gravity become the matter motion reason since four hundreds years!
No Planet Moves By The Sun Gravity- Newton is wrong- because-the planet moves by the force caused its creation- means- the planet creation and motion are done by the same one force otherwise this planet would be broken by effect of 2 forces on it- also – the mass gravity itself can't cause any motion- because – any motion produces energy and from what source to pay this motion energy- that would necessitate to decrease the mass itself by the motion energy value- it's not correct – the mass gravity connects two masses together- as a lorry and its trailer- if one mass moves the other will move with it but the motor is outer reason and not the mass gravity.
This refutation is not necessary- where the urgent question asks (Why Is The Matter Motionless By Nature? Who proved this idea?)- the matter is created from a movable energy and moves with it by nature- the mass gravity doesn't cause any motion in the universe. 
(3)
Let's answer (What's The Matter?)
The matter and space are created from the same one energy- and - If we suppose the space is similar to the sea of water, the matter be similar to a whirlpool or a vortex found on the sea page- means- the matter is a geometrical design distinguish from the space- as the whirlpool, it's created from the sea water but it has a distinguish picture from the sea waves picture
The whirlpool (vortex) is carried by the waves motion- similar to that- the matter is carried by its original energy and moves by it- No Mass gravity is required for the matter motion- means- the matter is movable by nature.
The whirlpool dimensions are defined by the sea water motion features- for example- we have a whirlpool its diameter is (2 meters)- this diameter is defined by the sea water motion velocity, the amount of the water and other motion features- by that- the water motion analysis explains how the whirlpool dimensions are created
Also- the whirlpool is created but the creation requirements are needed every day- means- even if this whirlpool is found since years it can be changed immediately if the water motion features are changed- means- the whirlpool creation process is NOT a historical one.
Also - the matter is similar to a creature muscle, the muscle is found based on the blood motion and without this motion the muscle can be changed or removed.
Similar to that- the matter is created based on a moving energy, if this motion is changed the matter dimensions will be changed also-
(4)
The previous matter definition is suitable for Lorentz transformation, where it was noticeable that Einstein had used 2 equations only of  Lorentz transformation (time and distance) for the space-time geometry and neglected the mass equation as it would be not found- where Lorentz 3 equations are created based on the same concept and by similar experiments- Einstein had neglected the mass equation (Not For Any Physical Reason) but for his own bias, believing that, the matter is found (regardless any motion), here my planet diameter equation proves the matter is created depending on the motion features which enable to put the mass value on a coordinate with the space-time geometry
(5)
What's The Major Idea I Try To Explain In This Discussion?
Example- Saturn diameter 12536 km, its mass 568 x 1024 kg, its orbital distance 1433 million km, its orbital period 10747 solar days, its orbital inclination 2.5 degrees, its axial tilt 26.7 degrees.
This data can tell us how Saturn is created and how its motion is done and what's its motion effect on the other planets- the neglect of the planets data removed the source of knowledge and left us with the imaginary ideas – let's use example for explanation
Example- The planet diameter equation proves the planet diameter is created based on its orbital incantation- NOW- Mars original orbit was between Mercury and Venus (I prove that in point no.**) and Mars had migrated from its original orbit – BUT- Mars diameter is created in its original orbit and depended on its original orbital inclination- and – after Mars Migration its orbital inclination is changed but its diameter equation still show the original orbital inclination because the diameter is created based on it
Shortly – the planet data is similar to the Creature Genes and can help to discover how this planet is created and how its motion is done
Thanks a lot

Apparently it makes me a “super villain” and an “evil scientist” to want to use a big big magnet to try to pull the planets in our solar system out of orbit. Personally I think it’s just good old fashioned scientific curiosity but whatever

"Now," my grandmother said, as she set two Mason jars on the counter in front of us, "I am not a scientist. I may get parts of this wrong. We'll just hope it isn't the important parts. But I don't think it will be, because--well, but I said that the last time, didn't I?"
Nothing could tempt me to answer that.
Tumblr media
Wendalyn said, "I'm sure you've been extra specially careful this time, Mom," and if she sounded a little mechanical saying it, well, I think that was understandable.
"I have," my grandmother said happily. "And while I am not a scientist, I am a cook and a baker. The problem was explained to me in those terms and in those terms, I think, I can explain it to each of you."
My grandmother deftly scooped sugar into both the jars, filling them each about two-thirds full. Then, she added cinnamon in a layer on top of the sugar. She left about an inch at the top of each jar before placing the lids on them.
She handed me one of the jars.
"Will you please shake that up for me, Velma? I'd like it well-mixed, so it may take you a minute or two."
I started shaking the jar. It was, in fact, going to take me at least a minute to get the mixture blended well. I could see that right away. When it looked right to me (and my arm was getting tired), finally, I set it down on the counter, looking a question at my grandmother.
She sighed.
Tumblr media
"Well, we aren't actually going to bake with it right now, so I guess that's close enough. What would you call this substance now, Velma? Is it cinnamon? Or is it sugar?"
Oh, for fuck's sake.
"It's both," I said.
My grandmother held up the other jar of cinnamon and sugar, the one that hadn't been mixed yet, and turned to my Aunt Wendalyn.
Tumblr media
"What would you call this substance, Wendalyn? Cinnamon or sugar?"
If the look on my aunt's face didn't read, "oh, for fuck's sake," then I'm a fairy myself. But, dutifully, she said, "It's both."
My grandmother frowned.
"Velma says hers is both, and you say yours is both, but they don't look the same to me at all."
"Mom."
I laughed. I couldn't help it. "Now you know," I said to my aunt, "what it was like for us when my mom became a teacher."
Tumblr media
My grandmother giggled.
"I'm not going to say what I think of that decision. But all right! It's been a long day. I'll get to the point."
She picked up my jar.
"Imagine this is a chunk of time. Don't laugh! I am doing my best as a non-scientist.
"So. The cinnamon molecules and the sugar molecules are all traveling together in time, and no one cinnamon molecule is ever very far from any one sugar molecule, or vice versa.
"They aren't the same substance, but they form one cohesive mixture; so in a sense, the time sense, they may as well be. If we poured some of this out into a dish, both the cinnamon and the sugar would appear to reach the dish at about the same time. They would travel together.
"Now imagine I had a magnet that attracted only cinnamon, and another that attracted only sugar--"
"Mommmmm!"
"Don't whine, Wendalyn, it makes me lose my train of thought. I don't think you want that?--No, I didn't think so.
"Now imagine I have these silly magnets, and that by putting one at each end of the jar, I can make Velma's mixed-up jar look just like your jar, Wendalyn. Where the cinnamon and the sugar are in the same jar, but still separate. If I poured some of this re-separated cinnamon and sugar into a dish, then, for the most part, the cinnamon would reach the dish before the sugar."
"And why would you want to do that?" said my aunt tiredly. "Why are they in the damn jars to--no. You know what, never mind. Go on."
But something felt like it was about to click for me.
"Grandma," I said, "are you saying that--okay. Is the cinnamon supposed to represent wherever we are now? Aurora Skies? And the sugar is supposed to be Elmira City?"
My grandmother raised her eyebrows slightly and said, "Go on, Velma."
Tumblr media
But I couldn't go on. That was as far as I had got. I frowned, trying to coax a little more out of my poor tired brain.
"So... you said that in the mixed jar... in the mixed jar, the cinnamon and the sugar were traveling together--oh! Oh, shit."
"What's 'oh, shit', Velma?" asked my aunt worriedly.
"'Oh, shit' is a perfectly natural (if somewhat vulgar) response," my grandmother said, "to the sudden realization that you have become separated from your home not only by place, but by time."
"Oh," said my aunt. "Oh, dear."
My grandmother was still smiling.
"I haven't told you the good news. The good news is that--if you'll pardon the pun--things should all shake out on their own in a week or two. Naturally! I've only caused a temporary, and really relatively teensy-tiny, misalignment of things."
My aunt and I were silent.
"Get it?" my grandmother said brightly. "Shake?"
She picked up Wendalyn's jar and began shaking it up, giggling.
My aunt turned to me.
"I hope you like French toast, Velma," she said. "From the looks of this? We're going to be having it kind of a lot."
"It's good in cookies, too," called my grandmother after us, as we trudged dejectedly out of the kitchen and up the stairs.

A simulated image of NASA’s Nancy Grace Roman Space Telescope’s future observations toward the center of our galaxy, spanning less than 1 percent of the total area of Roman’s Galactic Bulge Time-Domain Survey. The simulated stars were drawn from the Besançon Galactic Model.
Exploring the Changing Universe with the Roman Space Telescope
The view from your backyard might paint the universe as an unchanging realm, where only twinkling stars and nearby objects, like satellites and meteors, stray from the apparent constancy. But stargazing through NASA’s upcoming Nancy Grace Roman Space Telescope will offer a front row seat to a dazzling display of cosmic fireworks sparkling across the sky.
Roman will view extremely faint infrared light, which has longer wavelengths than our eyes can see. Two of the mission’s core observing programs will monitor specific patches of the sky. Stitching the results together like stop-motion animation will create movies that reveal changing objects and fleeting events that would otherwise be hidden from our view.
youtube
Watch this video to learn about time-domain astronomy and how time will be a key element in NASA’s Nancy Grace Roman Space Telescope’s galactic bulge survey. Credit: NASA’s Goddard Space Flight Center
This type of science, called time-domain astronomy, is difficult for telescopes that have smaller views of space. Roman’s large field of view will help us see huge swaths of the universe. Instead of always looking at specific things and events astronomers have already identified, Roman will be able to repeatedly observe large areas of the sky to catch phenomena scientists can't predict. Then astronomers can find things no one knew were there!
One of Roman’s main surveys, the Galactic Bulge Time-Domain Survey, will monitor hundreds of millions of stars toward the center of our Milky Way galaxy. Astronomers will see many of the stars appear to flash or flicker over time.
youtube
This animation illustrates the concept of gravitational microlensing. When one star in the sky appears to pass nearly in front of another, the light rays of the background source star are bent due to the warped space-time around the foreground star. The closer star is then a virtual magnifying glass, amplifying the brightness of the background source star, so we refer to the foreground star as the lens star. If the lens star harbors a planetary system, then those planets can also act as lenses, each one producing a short change in the brightness of the source. Thus, we discover the presence of each exoplanet, and measure its mass and how far it is from its star. Credit: NASA's Goddard Space Flight Center Conceptual Image Lab 
That can happen when something like a star or planet moves in front of a background star from our point of view. Because anything with mass warps the fabric of space-time, light from the distant star bends around the nearer object as it passes by. That makes the nearer object act as a natural magnifying glass, creating a temporary spike in the brightness of the background star’s light. That signal lets astronomers know there’s an intervening object, even if they can’t see it directly.
Tumblr media
This artist’s concept shows the region of the Milky Way NASA’s Nancy Grace Roman Space Telescope’s Galactic Bulge Time-Domain Survey will cover – relatively uncharted territory when it comes to planet-finding. That’s important because the way planets form and evolve may be different depending on where in the galaxy they’re located. Our solar system is situated near the outskirts of the Milky Way, about halfway out on one of the galaxy’s spiral arms. A recent Kepler Space Telescope study showed that stars on the fringes of the Milky Way possess fewer of the most common planet types that have been detected so far. Roman will search in the opposite direction, toward the center of the galaxy, and could find differences in that galactic neighborhood, too.
Using this method, called microlensing, Roman will likely set a new record for the farthest-known exoplanet. That would offer a glimpse of a different galactic neighborhood that could be home to worlds quite unlike the more than 5,500 that are currently known. Roman’s microlensing observations will also find starless planets, black holes, neutron stars, and more!
youtube
This animation shows a planet crossing in front of, or transiting, its host star and the corresponding light curve astronomers would see. Using this technique, scientists anticipate NASA’s Nancy Grace Roman Space Telescope could find 100,000 new worlds. Credit: NASA’s Goddard Space Flight Center/Chris Smith (USRA/GESTAR)
Stars Roman sees may also appear to flicker when a planet crosses in front of, or transits, its host star as it orbits. Roman could find 100,000 planets this way! Small icy objects that haunt the outskirts of our own solar system, known as Kuiper belt objects, may occasionally pass in front of faraway stars Roman sees, too. Astronomers will be able to see how much water the Kuiper belt objects have because the ice absorbs specific wavelengths of infrared light, providing a “fingerprint” of its presence. This will give us a window into our solar system’s early days.

This animation visualizes a type Ia supernova.
Roman’s High Latitude Time-Domain Survey will look beyond our galaxy to hunt for type Ia supernovas. These exploding stars originate from some binary star systems that contain at least one white dwarf – the small, hot core remnant of a Sun-like star. In some cases, the dwarf may siphon material from its companion. This triggers a runaway reaction that ultimately detonates the thief once it reaches a specific point where it has gained so much mass that it becomes unstable.

NASA’s upcoming Nancy Grace Roman Space Telescope will see thousands of exploding stars called supernovae across vast stretches of time and space. Using these observations, astronomers aim to shine a light on several cosmic mysteries, providing a window onto the universe’s distant past. Credit: NASA’s Goddard Space Flight Center
Since these rare explosions each peak at a similar, known intrinsic brightness, astronomers can use them to determine how far away they are by simply measuring how bright they appear. Astronomers will use Roman to study the light of these supernovas to find out how quickly they appear to be moving away from us.
By comparing how fast they’re receding at different distances, scientists can trace cosmic expansion over time. This will help us understand whether and how dark energy – the unexplained pressure thought to speed up the universe’s expansion – has changed throughout the history of the universe.

NASA’s Nancy Grace Roman Space Telescope will survey the same areas of the sky every few days. Researchers will mine this data to identify kilonovas – explosions that happen when two neutron stars or a neutron star and a black hole collide and merge. When these collisions happen, a fraction of the resulting debris is ejected as jets, which move near the speed of light. The remaining debris produces hot, glowing, neutron-rich clouds that forge heavy elements, like gold and platinum. Roman’s extensive data will help astronomers better identify how often these events occur, how much energy they give off, and how near or far they are.
And since this survey will repeatedly observe the same large vista of space, scientists will also see sporadic events like neutron stars colliding and stars being swept into black holes. Roman could even find new types of objects and events that astronomers have never seen before!

Best Greetings
The Solar System Depends On A Continuum Of Data
The continuum meaning is understood simply – let's imagine ten houses are built on some place has groundwater- the water is found under all houses even if they build walls to separate the houses from one another –
Shortly–the solar planets and their distances are created from the same one energy-  
Nothing is independent – for that – One Law controls all data
The solar system is similar to a river of water, some water is seen clear and other has some dust (clay), some water is in whirlpools form and other in waves form- different forms for the same water-
The idea is acceptable, because the energy has different forms, although the energy content is similar and we can use the electricity in place of the oil and can use the nuclear in place of electromagnetism, different forms for similar content- this explains the solar system creation concept, the planets matters and distances are created from the same one energy and all of them are controlled by one law and for that the system basic feature is (The Continuum Of Data)
I have 2 proves for this fact  
(Proof No.1)
The planets data is defined based on exact equations– means-
Planet diameter, mass, orbital distance, period, velocity, inclination, rotation period, axial tilt and all data is defined based on exact equations
that proves one law controls all data 
shortly
I  have 5 (five) equations by which the planets data can be concluded theoretically- means – suppose we know one data only (Mercury orbital distance =57.9 million km) by this one data and by my five equations we can conclude theoretically all planets orbital distances, periods, velocities, inclinations, DIAMETERS, masses, rotation periods and axial tilts- this data is concluded theoretically
That disproves the book concept tells (planet creation data is created by random process, initial conditions and historical unknown factors)
On the contrary- based on geometrical rules the data is created
 Notice
The airplane manufacturer needs exact equations to define the airplane length, width, weight and all data otherwise this airplane can't fly safely– similar to that- the planet creation data is defined based on exact equations otherwise this planet can't move safely. 
(Proof No.2)
The Distances In The Solar System Are Created In One Network Of Distances
Here – we don't deal with separated distances from one another but we deal with one group of distances are created together based on ONE DESIGN.
Shortly–the solar system distances are similar to the chess board distances– they are created together based on one another and all of them are designed based on One Geometrical Design- that makes the planets distances one Network
Thanks a lot – kind regards

« To mention the global loss of biodiversity, that is to say, the disappearance of life on our planet, as one of our problems, along with air pollution or ocean acidification, is absurd—like a doctor listing the death of his patient as one symptom among others.
The ecological catastrophe cannot be reduced to the climate crisis. We must think about the disappearance of life in a global way. About two-thirds of insects, wild mammals and trees disappeared in a few years, a few decades and a few millennia, respectively. This mass extinction is not mainly caused by rising temperatures, but by the devastation of natural habitats.
Suppose we managed to invent clean and unlimited energy. This technological feat would be feted by the vast majority of scientists, synonymous in their eyes with a drastic reduction in CO2 emissions. In my opinion, it would lead to an even worse disaster. I am deeply convinced that, given the current state of our appetites and values, this energy would be used to intensify our gigantic project of systemic destruction of planetary life. Isn't that what we've set out to do—replace forests with supermarket parking lots, turn the planet into a landfill? What if, to cap it all, energy was free?
[...C]limate change has emerged as our most important ecological battle [...] because it is one that can perpetuate the delusional idea that we are faced with an engineering problem, in need of technological solutions. At the heart of current political and economic thought lies the idea that an ideal world would be a world in which we could continue to live in the same way, with fewer negative externalities. This is insane on several levels. Firstly because it is impossible. We can't have infinite growth in a finite world. We won't. But also, and more importantly, it is not desirable. Even if it were sustainable, the reality we construct is hell. [...]
It is often said that our Western world is desacralised. In reality, our civilisation treats the technosphere with almost devout reverence. And that's worse. We perceive the totality of reality through the prism of a hegemonic science, convinced that it “says” the only truth.
The problem is that technology is based on a very strange principle, so deeply ingrained in us that it remains unexpressed: no brakes are acceptable, what can be done must be done. We don't even bother to seriously and collectively debate the advisability of such "advances". We are under a spell. And we are avoiding the essential question: is this world in the making, standardised and computed, overbuilt and predictable, stripped of stars and birds, desirable?
To confine science to the search for "solutions" so we can continue down the same path is to lack both imagination and ambition. Because the “problem” we face doesn't seem to me, at this point, to be understood. No hope is possible if we don't start by questioning our assumptions, our values, our appetites, our symbols... [...] Let's stop pretending that the numerous and diverse human societies that have populated this planet did not exist. Certainly, some of them have taken the wrong route. But ours is the first to forge ahead towards guaranteed failure. »
— Aurélien Barrau, particle physicist and philosopher, in an interview in Télérama about his book L'Hypothèse K
