In General Relativity, there are time-like curves. In Quantum Mechanics, there is Entanglement. So consider this: **two particles A and B separating, while they are still entangled. Suppose A is on a time like curve. **Suppose A takes 1,000 seconds in B proper time to go around its time like loop. Suppose we activate entanglement at 999 seconds. **Then, A cannot show itself exactly as if it was before, having completed its time like loop, because the entanglement with B has disappeared…** No problem will the Copenhagen Interpretation fanatics sneer, we just create a new A, with a new entanglement…

Whatever. Hard to argue with the unbalanced.

The fact is entanglement doesn’t resist time-like loops. Ergo, those can’t happen. Or then entanglement doesn’t resist the (proper) time needed for a time-like loop: thus my own SQPR theory appears in its full glory.

Let me give another logical axis on the subject: **While particle A goes along the putative closed time loop, entanglement with B, the particle A is entangled with, from an action at B, at any moment, can break the entanglement with A, breaking the time loop with an event (what I call a “Quantum Interaction”) extraneous to it.**

In any case, one, or both of the two pillars of Twentieth Century physics collapses…

One may naturally ask what happened in my own Sub Quantum theory, SQPR.

In SQPR the entanglement from B to A is not instantaneous (contrarily to the usual Quantum Mechanical formalism, which has the entanglement propagating instantaneously, just as Newtonian Mechanics had gravitation instantaneously propagating… until Laplace made gravitation into a field with a finite propagation speed, 80 years later, or so (that implied gravitational waves, as Laplace pointed out in the first edition of his book).

This being said, that finite propagation speed doesn’t mean the entanglement can’t break the loop. Generally it will: entanglement moves at 10^23c, whereas a typical time loop is found around a Black Hole, over small dimensions. Hence SQPR gives a definite answer: time loops can’t exist. Indeed an object is a continual succession of delocalization-relocalization-entanglement-collapse entanglement. Hence any inchoating time loop would broken instantaneously… So the scenario pushed by some specialists of Relativity, and spread by Hollywood, that Black Holes would enable time travel is impossible.

Philosophically, the approach is interesting: generally General Relativity, Celestial Mechanics and Quantum Mechanics are viewed as having nothing to do with each other. That traditional view is well-known. A famous theoretical physicist was proclaiming it as recently as last week. As I heard it again, last week, I was pondering how can one be so famous, and so wrong in the precise field in which one is famous… (In a nutshell: General Relativity comes from Relativity, which itself comes from Photon Mechanics, also known as “Electrodynamics”, which is the simplest form of Quantum Mechanics…)

Then it dawned to me that this stupid meta-idea, that General Relativity and the Quantum have nothing to do with each other, is so well anchored that none of the fools out there may have thought to force them in the same logical box… Moreover, entanglement appeared only in 1935, with the EPR paper (and Schrodinger naming entanglement “entanglement”, directly in English), so it escaped the furious debates between De Broglie and Einstein on one side and Bohr, Heisenberg, and the entire Copenhagen school, on the other… Thus, I added entanglement to loops… No need to “shut up and calculate…”

**Distant ideas gather much energy, when they are made to crash into each other…**

Some may sneer: how likely is it that Patrice fell on a major idea in physics so obvious that even normal physicists can understand it? Well, it would not be the first time something similar happens. Actually, way worse has already happened. And no, I am not alluding once again to the discovery of E = m by Jules Henri *Poincaré* in 1899, and attributed to Einstein…

Remember the Bohm-Aharonov effect? This says that a change of potential P will have an effect on Quantum Mechanics driven particles, even if the field F that P gives rise to (F = dP) is unchanged. That was thought of in 1959, and immediately checked experimentally on electron interference through the famous 2-slit. The idea should have been obvious. The most basic equation on Quantum Mechanics is the De Broglie-Schrodinger equation (usually attributed only, erroneously, to the latter…) This is basically: i(dwave)/dt = P. So the variation of the wave as a function of time, multiplied by the square root of (-1) is equal to… the potential. All the immense minds of QM, including Einstein, De Broglie, Bohr, Heisenberg, Pauli, Sommerfeld, Born, Von Neumann, Ehrenfeld, Fermi, the Curies, Dirac, Feynman, Yukawa, Schwinger, Tomanaga, Wigner, Weyl, etc. look at the equation, and didn’t realize the potential mattered…

The Aharonov–Bohm effect was chosen by the *New Scientist* magazine as one of the “seven wonders of the quantum world… Out of vengeance, probably, the rogue David Bohm, and Aharonov, didn’t get the Nobel anymore than those who discovered the spin of the electron…

The conclusion you escaped so far: Recently discovered (June 2019) Sub Quantum Mechanics, in conjunction with Quantum Entanglement, introduces an arrow of time at a Sub Quantum level…. making all previous considerations on the subject obsolete…
