Sick and tired of hearing about how we "don't understand gravity." We know exactly how it functions, and exactly how to calculate gravity in any given system.

Yes, I am aware we don't know what causes gravity. Are we aware what causes the "strong and weak nuclear forces" which are very poorly modeled, and poorly understood? Do we /really/ know for sure why it is that a whole bunch of protons like sticking around together? Why is that?

Or is it just because scientists like to pretend that it's easy to understand things sticking together like peanut butter on bread, but they're too autistic to admit that they comprehend objects innately pulling themselves towards each other?

Without getting into existence, I am going to agree with this guy: dimensionality does not exist.

What you think of as a dimension is just a factorization of your spatial experience along the lines of orthogonal motion. Since motion of what you are calling a mass through what you are calling space is affected only by what you call forces acting along three orthogonal directions, you can separate those directions into separate force stories.
You can then expand that factorization to something you call time. But you can never have a physical story that does not include everything. There are no 2 or 1 or 4 dimensional objects. Physical objects are just physical objects. Without the orthogonality of motion you would never have made up dimensions.

What Hume should have made clear was not just that the whole that you are cutting up creates the parts that you then say lead to the whole and allow you to deduce missing parts and induce wholes from the parts from other stories that turn out the same, but also that you can't just switch stories just because they use the same parts, because there are different narrators that can and cannot see those parts.

Your dimensionality requires a narrator that can see in 2 and 1 dimension, but that narrator has no existence outside of the problem you use that story to solve, as evidenced by Hamiltonian methods that solve these problems without dimensionality at all. Better rip that bandaid off right now before it creates problems down the road.

>> No.11123837

Gravity is a compression wave in the aether. It's as simple as that. Mass isn't pulled towards other masses by attraction. Mass is pushed by collision with the aether, and gravitation is a result of simple interference between compression waves in the aether. Gravity is essentially acoustic in nature. It's all about resonance.

Literally just energy-mass points averaging toward each other, ut because that average is on a delay, they average toward their past locations, thus causing rotation rather than direct attraction. You can simulate this relatively easily.

>> No.11124174

>>11124166

... to continue, now you might wonder why energy-mass averages, well it's simple really, its because averaging is the mathematical operation that conserves quantum energy-density information across space - conservation of energy essentially.

Now, why does the Universe act this way? Conservation, locality, interaction?

Listen. When your theory, in this case "Infinite regress" or whatever the fuck that means, doesn't match your data, which is, in this case, an elementary observation so simple even children understand it, that being that directions are a thing, and that there can be multiple of them, you toss the theory away.

(2007) The Physical World as a Virtual Reality:

>The maximum speed a pixel in a virtual reality game can cross a screen is limited by the processing capacity of the computer running it. In general, a virtual world’s maximum event rate is fixed by the allocated processing capacity. In our world, the fixed maximum that comes to mind is the speed of light. That there is an absolute maximum speed could reflect a maximum information processing rate

>On a distributed network, nodes with a high local workload will slow
down, e.g. if a local server has many demands a video download may play slower than usual. Likewise a high matter concentration may constitute a high processing demand, so a massive body could slow down the information processing of space-time, causing space to “curve” and time to slow. Likewise, if faster movement requires more processing, speeds near light speed could affect space/time, causing time to “dilate” and space to extend. Relativity effects could then arise from local processing overloads.

We cannot "understand" it because it's too weak for experiments on a subatomic scale, thus eluding us from combining quantum physics with relativistic effects. It's like one of those pictures that only take shape from far away but if you get closer it's just a blurry mess and no resemblance to anything. I think that we will not truly understand it for a couple hundred years. But stuff like LISA might shorten it to a couple decades.

This is just a consequence of chemicals being materials in our world. As an emergent property of the universe the questions about gravity that matter and that we lack understanding of is the same for chemicals, you being able to use knowledge of chemicals to create weapons really is on the same level as using knowledge of gravity to create satellites. Neither is representative of understanding these things on the level that would truly mean you understand.

These are just constructed differences really, just because chemicals are a material and can be manipulated because they have a material presence in our world does not mean we understand them.

It's just more 'interesting' to some when it comes to gravity because it doesn't have a material presence in the universe.

planck: J s

density black hole: kg/m3

>> No.11130301

>>11130300

now think about the following: someone defines a physical quantity descriptor, an extensive state size.
so this size is related to something, like the m3 in density.
at the limits of a mathematical system there are always simplifications and independencies of solution parameters.
so it would be quite conceivable that general descriptive variables of our system here are getting independed to the number of the dimensions used for such a extensive state size.
would mean the number of the spatial dimensions in density of a black hole for example (above 10^6 kg/m3) are no more relevant. one could also write kg/m2 or kg/m, as the
magnitude of the scalar hits the limit and the scalar becomes a limit value.

now back to the limits of our system with that idea in mind.

the units are (ENERGY * TIME) and (MASS / SPACE). >compare units and enjoy chiasmus first. think about theory of relativity.

interestingly enough, we were able to determine planks effective quantum precisely (6.626070..*10^-34 Js), whereas the critical density is only blurred.

core of my thesis: plankch is also an "extensive state size", which is just not observable by us, and the exponent of time is 3 in fact.

>nothing seems to be hurt, even the theoretical physicists with the emergence of the universe on base of quantum fluctuations get their money's worth.
ok, this would mean we have two things-objects-whatever, THE (dimensional time) and THE (dimensional room), both equal on the basis of my previous assumptions.
but they are different. space dimensions are apparently on an equal footing, time dimensions are not. or at least not in our understanding.

completion of my thesis: without knowing how the superior interaction of the two things works, one can only guess.
you me it feels correct to call the interaction a interference of two objects.
