What if recent stagnation in physics is deliberate?
I.e. some world-threatening* physics was discovered and it had to be buried by governments to preserve humanity...

*threatening how?
Well, imagine if there was a phenomenon that would allow every random retard to build equivalent of nuclear bomb from readily available items...
How could you safely make such knowledge publicly available?

Which one of these two outcomes is more physically likely?

Its not a magical mirror, its a wormhole. If it was a magical surface that teleports things at an atomic level then this problem would rip apart the cube into atoms.
A wormhole connects two places at once seamlessly like a doorway, atoms are not being teleported in any way, space has just been folded onto itself and a tunnel was created to connect the two spatial planes.
The difference with a conventional doorway is that this door has two doorways, but at the same time its one doorway.
If the current laws of physics are true then "B" is the only possible answer. The doorway moving towards the cube is the same as all of space moving towards the doorway, the doorway doesnt really move cos its just a fixture connecting two points of spacetime. When whatever passes through the doorway it maintains its momentum on the other side, which is not moving (or rather moving with space in opposition to the other side of the doorway).
>>
>>14506587
Einstein BTFO!
>>
>>14502850
The problem with this thing is the fact that a wormhole wouldn't be attached to a surface like that, and it wouldn't be capable of being "moved" like that
A wormhole connects two points like the anon above said but he got it wrong, wormholes are like blackholes, they warp space around them, they cant be attached to a wall or something like in Portal, they would simply warp space around it
So the problem is impossible because it could never physically happen, you couldn't have a moving wormhole while the other side of the same wormhole was stationary because space is relative
Its just not possible
>>
>>14502850
Neither because both require laws of physics to be broken.
A requires the cube to be moved without having momentum and B requires the cube to gain momentum from nothing.
>>
>>14507537
Actually let me clarify a bit what I said at the end there
Wormholes are theoretically made up of matter called exotic matter and if that matter is moving then the wormhole moves too, I'm not an expert on wormhole theory (and its all bullshit, exotic matter is probably bullshit), but it doesnt seem logical for one "end" of a wormhole to be able to be moved without the space warping on either "side" of the wormhole being moved too, if you push it on one side it should move on the other side too so the spacetime warping remains consistent, if it becomes inconsistent I imagine it would simply collapse into a blackhole
Also if you did put something through the wormhole, even though its effectively the same thing as just passing through regular space, its velocity wouldn't be the same at the other "side" due to gravity. It would certainly have a change in velocity, so if A did happen it wouldnt just plop on the ground, it would accelerate to a certain degree.

The spectrum goes between having consistent but completely outlandish and untenable beliefs, and having a bunch of inconsistent but pragmatic beliefs that work under the right circumstances. There is no one on the left end of the spectrum, though plenty of people are imbalanced in that direction, embodying worst of both worlds. Being on the right side only becomes a problem when you try to formalize and systematize your ad hoc beliefs into some kind of weird Escherian mental structure, because then it starts to dictate your logic of behavior and becomes resistant to change. This truth that makes pseuds seethe.

Imagine a cubic box with a bunch of ball bearings in it perfectly packed in. You can touch touch the balls on one open side of the box, and the other sides have detectors and everything;

You take a hammer and eye up a random ball around the middle of the open side.

One time you hit it gently, then medium strength, then full strength, after waiting like 20 seconds in between hits.

The energy wave the ball you hit with the hammer will be different energy levels depending on the force/accleration of your hit, yes?

Will that energy propagate from ball to ball at the same velocity each trial hit?

Will the energy wave be of the same nature traveling the direction of your hammer swing, as opposed to up and down perpendicular to it?

I believe that physics is both local and non-local. Rather than a property inherent to physics, I believe this is a property of the environment. Stated accurately, I believe that our universe utilizes both localized and geometric expressions of physical phenomena.

These beliefs are presented for the sake of completion, they are not required to test my hypothesis. The specific math present in the universe involves "zeroes collection" at the edge of discrete phenomena, which are used to paint higher order laws such as conservation of mass and energy. We can explore the full implications of this model later, for now there is an alluring hypothesis we should probably focus on.

According to my models, natural phenomena have a dissipation rate (due to the unstructured environment) in the mathematics of vibration that are purely virtual and offer no constraints to intentional resonance. Should this prove correct, it may be possible to construct an environment where the resulting waveforms produce an overunity in specific bands. The hypothesis I'd like to propose could provide us not with free energy, but a controlled, periodic surplus of measured energy ordered in a form we'll have to devise (since it otherwise wouldn't have occurred naturally). I'm certain that the math can produce overunity, but I don't have sufficient basis to predict how this would affect a given environment. I'm also not certain if the overplus could perform useful work in a system, but figured that we can at the very least discuss it.


We should be able to construct a fairly trivial hypothesis for this.
>>
>>14506463
One could say I'm resonant in your hypothesis. I'm reminded of paper related, whose conclusion states that "We inhabit a 3D hologram, embedded in an infinitely-dimensioned imaginary hyperspace. Matter, forces and energy emerge from the geometry and curvature of this complex spacetime. The bedrock foundation of the entire universe is multi-dimensional mathematics." In it quotes Maxwell's (actual apostrophe, unlike the gibbs heaviside equations masquerading beneath his name)
>“The peculiarity of our space is that of its three dimensions, none is before or after another. As is ‘x’, so is ‘y’, and so is ‘z’. If you have 4 dimensions, this becomes a puzzle. For first, if three of them are in our space, then which three? Also, if we lived in space of ‘m’ dimensions, but were only capable of thinking ‘n’ of them, then first, which ’n’ ? Second, if so, things would happen requiring the rest to explain them, and so we should either be stultified or made wiser. I am quite sure that the kind of continuity which has four dimensions all co-equal, is not to be discovered by merely generalising Cartesian space equations.” — James Clerk Maxwell, in correspondence with C.J. Monro, Esq., 15
Mar 1871[2]

If , such a hypothesis is to be taken at face value, than the informationalists obviously have explications, for if entropy is conserved riding a non-commutative or non-associative shortcut through hyperspace than nature may well be performing it.

I consider the natural dissipation of charge density into the environment, especially from a geometric algebra perspective that charge density is a current flowing not in L but in T. Charge density, as one is aware by the mass-energy relation, coincides with gravitation, or perhaps mathematically, the re-geometerization of the environment.

such theorizing's lead me to consider electrons, or perhaps wider varieties of subatomic particles (I'm still filtered by Cohl Furey's bioctonion stuff https://www.youtube.com/watch?v=_E2iiuunK-E&ab_channel=QuantaMagazine) are like self recursive warp bubbles of charge. the electro and magnetostatic forces dissipate, but the concentration of charge density warps the environment back in on itself. I believe this analog to be equivalent of the model in
https://www.slideshare.net/LarryReed15/fine-structure-constant-250303032

where the apparent charge of the electron is dissipating equal to a Casimir vacuum effect generated by the frame dragging of electrostatic forces inside the particle. When i was greeter with your idea of looking for zeros, my mind jumped here for some reason
>>
>>14506558
My basic problem with holographic models like that is their capacity to model (and predict) literally anything. They don't give us bearing in hyperspace, so we're forced to construct arbitrary submodels to create predictive domains in. Collating so many models is what led to my current understanding, which was mostly just looking for correlations in hyperspace (like most theoretical intuitions).
>>14506593
>some reason
That's correct. All of physics necessarily occurs along the charge density gradient, and vacuum is one of the zero edges. These subtle effects at the edge of definition are precisely where the math needs to be examined most for us to gain a dimensional bearing that isn't imaginary (or holographic, if that's clearer).

Resonant effects wouldn't be noticed in a holographic universe because it lacks the compounding texture of material physics.
