BOOSTING a CAVITY FABRICATES BLACK HOLES. Thus NOT ALL INERTIAL FRAME ARE EQUIVALENT
The Principle of Relativity is that the physical laws are the same in all inertial frames. However, armed with Gravitation theory and Quantum physics, we find that the SPEED OF A FRAME, IF HIGH ENOUGH, CAN BE DETECTED WITHIN THE FRAME. Although quite simple, the idea is new, and it brings a serious contradiction with COVARIANCE.
Fundamentally the setup of the counterexample is similar to the so-called “Twin Paradox”. The “Twin Paradox” is a real effect, fully transparent theoretically and thoroughly checked experimentally. GPS uses the relativistic slowing of time trillions of times per hour. Similarly the counterexample produced here should be just as real, given that the most basic aspects of General Relativity and the Quantum are correct.

Suppose we put a visible photon between two imaginary mirrors of mass zero ar rest in frame A. Then we accelerate A. At what speed will the photon P be so short, and thus its frequency, hence energy, so high that it will make a black hole?
Well, that can be calculated easily.
In the rest frame of A, the photon’s energy is: E = hc/λ The photon is bouncing around the cavity, in the direction of the boost v. To simplify we make the photon a standing wave (it has to). Here is the reasoning in a page:

The Planck scale, 1.616×10^(−35) meter, was initially derived (by Planck) from a purely dimensional argument. Later a derivation from the Uncertainty Principle was found In blue in the page above). Now we have found a completely new derivation, and it is most troubling: whether a Black Hole exists or not should not depend upon which class of inertial frames one considers… That’s called covariance. Exposed to the preceding common traditional relativists would say that the reasoning can’t possible be true. However, it is: the proof is transparent.
Notice that if we put not one, but a trillion photons in the standing wave, the criticality is reached at roughly 10^ (-29) m….
To turn a 1-meter-long mirror cavity containing a single visible photon (500 nanometer) into a black hole in some boosted frame, the required Lorentz factor is: Gamma ~ 6. (10^30). This corresponds to a speed extremely close to the speed of light: within (10^(-61)) c!
To make matters worse, one can easily devise a machine to carry along B that will allow to find out when the Black Hole has happened… without looking outside.

PATRICE’S INFERNAL MACHINE TO BREAK RELATIVITY:
-
Patrice Ayme builds a LONGITUDINAL light clock (i.e., with its axis along the direction of motion; to prove time dilation one uses instead perpendicular light clocks).
-
It emits photons through a tiny slit — 1 photon per Time Unit (TU) at rest.
-
Patrice ultra-boosts the system.
-
Time dilation means: fewer photons escape per external time unit (i.e. as seen from A). But in B’s frame, the rate is unchanged.
-
At extreme boosts, the total energy density in the boosted frame (according to an external observer in A) becomes so high that the system should form a black hole (by the hoop conjecture or similar criteria; or the demonstration earlier in this essay).
-
Once this happens, no photons can escape.
-
The internal observer notices this — because their previously regular photon emission halts. The energy in the cavity COMPLETELY STOPS decreasing.
-
Therefore, the observer in B can infer that a horizon has formed around them — from INTERNAL OBSERVATIONS ALONE.
This seems to imply that the Principle of Relativity breaks down: the B-frame observer detects an “absolute” velocity — because moving fast enough makes them a black hole, and they can tell from inside…

Key Differences: Frame-Dependence vs. Frame-Independence
The boost-induced collapse is frame-dependent: in one frame the system looks safe; in the boosted frame, it becomes a black hole. The traditional derivation is frame-independent: it’s about the absolute energy needed to localize a particle. Role of Quantum Mechanics:
In the boosted case, quantum mechanics isn’t needed up front — it’s a classical GR + SR argument. But it indirectly relies on the photon’s quantum nature for the energy content. In the traditional derivation, quantum mechanics (uncertainty principle) is essential from the start.
Operational Meaning: The boosted collapse shows you can’t “hide” gravitational collapse by going to a boosted frame — a kind of consistency requirement for GR + SR.
Both perspectives converge on the idea that:
The Planck length is the smallest length scale that can meaningfully exist without producing a black hole — no matter the frame, method, or energy involved.
So whether you’re:
-
Trying to confine a particle to pinpoint precision,
-
Boosting an innocent-looking mirror cavity to relativistic speeds,
-
Or considering the behavior of light near extreme energies,
— in all cases, spacetime itself “pushes back” once you cross the Planck scale. This is the smoking gun for quantum gravity [1].

Simplicio: You demolished Relativity, and you can’t possibly be right, yet you are. Are you happy with yourself?
Patrice Ayme:
When physicists tried to reconcile Quantum Mechanics and Relativity, many thought that QM was wrong, as Sir Roger Penrose thinks and said recently. Penrose got the Nobel Prize for his research on Black Holes. Evidence, experimental, and theoretical, is accumulating that QM is wrong. But the EPR experiments show that the most NAIVE interpretation of Relativity are also wrong when they pretend to deduce time travel from Faster Than Light.
Now the preceding is different: it is a direct contradiction of ultrafast speeds and the Principle of Relativity itself. In light of EPR effects, which have been experimentally checked, that’s not surprising. It is hilarious that Einstein, who plagiarized (stole) Relativity from Henri Poincaré and K. Lorentz (and several other contemporaries who also played a significant role), ended up burying Relativity with the “spooky action at a distance” (after talking extensively to the philosopher Karl Popper on the subject; Popper contributed non-trivially… There is a Popper version of the EPR!). BTW, Einstein and others had all the elements for the preceding reasoning, so why didn’t they come up with it? Well one is not motivated to prove what one considers wrong, or hateful…
Einstein, one of the creators of Quantum Mechanics (in more ways than one!), was highly motivated to prove that the Copenhagen Interpretation of the Quantum, CIQ, was sick… Einstein was not motivated by proving his alleged masterpiece, Relativity, was WRONG.
But it is [2].
Both Relativity and Quantum Mechanics are wrong: there is hope…
Patrice Ayme.

[1] After the Boosted Cavity has turned into a Black Hole, it forms a mostly flat gravitational field according to something akin to, but much worse than the Aichelburg–Sexl metric (Peter C. Aichelburg and Roman U. Sexl,“On the Gravitational Field of a Massless Particle”,General Relativity and Gravitation, Vol. 2, Issue 4, pp. 303–312 (1971)). The gravitational field of the boosted particle(s) is flattened into a plane shockwave, perpendicular to its direction of motion. I suggested this inescapable conclusion (the field can’t escape) at Stanford U decades ago and was laughed out… Yau called that “absurd”… With friends like that, who needs enemies? He went on to go to Harvard, the plutocratic U…
