For Immediate Consideration
If negative energy densities are used in quantum-wormhole-associated types of advanced quantum energy teleportation and quantum entanglement, and even though science's current understanding refutes the possibility, we should at least consider devising experiments with gravitational interferometers to test for quantum entanglement that overshadows the no-signaling theorem and the no-communication theorem.
Main Premises
There could be a "Communication Theorem" instead of a "No-Communication Theorem" in quantum entanglement if we could measure and manipulate negative energy.
According to the ER=EPR conjecture by Susskind and Maldacena, traversable wormholes—which are postulated to require negative energy (or a vacuum force)—in our perspective might be equivalent to a "Communication Theorem" in quantum gravity.
Furthermore, the application of negative energy in quantum entanglement could bypass the conventional requirement for Bell-state measurement and classical communication, which are necessary in standard quantum teleportation protocols.
Speculation #1
What if it is possible to have a sustained negative energy density sent from the future, as this would bypass the quantum inequality that forbids sustained large amounts of negative energy density due to the approaching infinitesimally short amount of time of the density's existence time, and what if this negative energy density was used to open a wormhole or make a type of quantum entanglement where a wormhole is associated? The idea here is that the requirement for shorter periods of time could approach the instant of the present and pass it into negative time/the past. This would use postselection closed timelike curves (P-CTC) and quantum energy teleportation. And what if in this advanced form of quantum entanglement, perhaps labelled P-CTCQE, time dilation is used such that Bob, who is in the present instances connected to Alice, experiences more time, but at every instant of his time, he sends negative energy through negative time to Alice.

Speculation #2
Could one use the experiment by Aephraim Steinberg, a physicist at the University of Toronto, that showed photons can spend a negative amount of time in an excited state in a way similar to Speculation #1?
Evidence of ‘Negative Time’ Found in Quantum Physics Experiment
https://www.scientificamerican.com/article/evidence-of-negative-time-found-in-quantum-physics-experiment/
Would it be possible to make the photon(s) perform the Bell-state measurement, but begin sending the measurement to a particle or field that performs the local operation, in a negative amount of time?
Does this create a volume of space with negative energy density?
Could you then use this negative energy density to super‑entangle another quantum system?
Speculation #3: Symmetric Retrocausal Energy Teleportation (SRET)
Two‑Way Negative Energy Densities with Shared Unitary Operation
Based on our preceding analysis, this speculation extends the P‑CTC + QET framework to a time‑symmetric closed loop in which both Alice (past/present) and Bob (future) end up with localized negative energy densities. Moreover, the two local unitary operations may not be independent—they could be different facets of a single, shared unitary that acts across time.
Below is a full, self‑contained write‑up of Speculation #3.
1. Motivation
Speculation #1 proposed using a future‑sourced negative energy density (via P‑CTC and QET) to bypass quantum inequalities and stabilize a wormhole. Speculation #2 attempted to ground the “negative time” effect in photon experiments, but was found insufficient for retrocausality.
A recurring difficulty was the asymmetry of the mechanism: only one party (the one applying the local unitary) receives negative energy. However, a traversable wormhole or a super‑entangled spacetime fabric might require negative energy at both mouths—both past and future ends.
Speculation #3 therefore asks: Can we design a self‑consistent retrocausal loop where both Alice and Bob generate negative energy densities, and their unitary operations are two aspects of a single, time‑symmetric transformation?
2. Core Idea
Let Alice be located at an earlier time tA (the “past” or “present”) and Bob at a later time tB (the “future”). They share a maximally entangled quantum state (e.g., a Bell pair). In addition, the entire setup is embedded in a postselected closed timelike curve (P‑CTC) that enforces consistency between the past and future.
The novel elements of Speculation #3 are:
Two‑way information flow:
– Alice performs a measurement and sends her result forward to Bob (normal QET).
– Bob performs a measurement and postselects a specific outcome, sending a hint backward to Alice (P‑CTC).
Two‑way unitary application:
– Using the forward hint, Bob applies a local unitary UB → negative energy density appears at Bob (future).
– Using the backward hint, Alice applies a local unitary UA → negative energy density appears at Alice (past).
Shared unitary operation:
Instead of UA and UB being independent, they arise from a single, time‑symmetric unitary transformation Utotal that acts on the combined Hilbert space of both parties. The local operations are “shadows” of this global unitary, projected onto past and future.
In mathematical terms, if the global quantum state is ∣Ψ⟩, then:
Utotal∣Ψ⟩=∣Ψ′⟩
where the reduced density matrices at tA and tB evolve as:
ρA′=TrB(Utotal ρAB Utotal†), ρB′=TrA(Utotal ρAB Utotal†)
and each evolution lowers the local energy density below the vacuum value, i.e.,
⟨ψ′∣T00(xA)∣ψ′⟩<0, ⟨ψ′∣T00(xB)∣ψ′⟩<0.
3. The 5‑Step Process
We outline a plausible sequence that respects causality (except for the P‑CTC bridge).
Step 0: Entanglement Preparation (Shared Past)
A source at an even earlier time creates a Bell pair (QA, QB) and sends QA to Alice and QB to Bob. This is the quantum resource.
Step 1: Alice’s Forward Measurement (Past)
Alice measures her half of the Bell pair together with an ancillary system that will later be used for her local unitary. She obtains a classical outcome mA. She does not yet apply any unitary. The outcome mA is stored and will be sent forward to Bob.
Step 2: Bob’s Backward Measurement & Postselection (Future)
Bob receives his half of the Bell pair and also a second quantum system (the “future ancilla”). He performs a Bell‑state measurement that entangles his qubit and the ancilla. He then postselects on a specific measurement outcome mB∗.
This postselection is the core of the P‑CTC: only experimental runs where Bob obtains mB∗ are kept.
The postselection effectively sends a retrocausal signal to Alice, informing her which local unitary she must apply to make the whole history self‑consistent.
Step 3: Backward Information Transfer (via P‑CTC)
As a result of the postselection, Alice in the past receives a “hint” H. This hint is not a classical message but a quantum condition: it tells her which of several possible unitaries to apply. The process is analogous to teleportation backward in time.
Step 4: Alice Applies Her Unitary (Past)
Conditioned on H, Alice applies a local unitary UA to her half of the Bell pair (and possibly to her ancilla).
According to quantum energy teleportation (QET), this operation creates negative energy density at Alice’s location.
Because the hint came from Bob’s future postselection, the negative energy appears in the past—exactly where needed for wormhole stabilization.
Step 5: Bob Applies His Unitary (Future)
Meanwhile, Bob has also received Alice’s forward classical outcome mA (sent normally at light speed). Conditioned on mA, Bob applies a local unitary UB to his system.
This is standard forward‑time QET, generating negative energy density at Bob’s location (future).
4. The Shared Unitary Hypothesis
The two unitaries UA and UB are not chosen independently. They derive from a single, global unitary Utotal that respects the P‑CTC consistency condition:
Utotal=UA⊗UB?
Not exactly. In a time‑symmetric CTC, the global evolution must satisfy:
Trenvironment[Utotal(∣Ψinitial⟩⟨Ψinitial∣)Utotal†]=ρfinal
with the condition that the reduced states at tA and tB are fixed points of the combined forward‑backward map.
A stronger speculation: UA and UB are the same unitary expressed in different bases, or they are two halves of a single non‑local gate (e.g., a controlled‑U where control and target are separated in time). In the most radical version:
Ushared=e−iHglobal(tB−tA)
where Hglobal contains negative energy density terms that act simultaneously on Alice’s and Bob’s systems. The local negative energies then appear as expectation values of the local stress‑energy tensor:
⟨T00(xA)⟩=⟨ψ∣ϕA†ϕA∣ψ⟩ren<0, ⟨T00(xB)⟩=⟨ψ∣ϕB†ϕB∣ψ⟩ren<0.
5. Consequences & Novel Predictions
If Speculation #3 were physically realized, it would lead to:
Sustained, two‑sided negative energy – both mouths of a wormhole could be propped open simultaneously, potentially making it traversable in both directions.
Symmetry of retrocausality – the past and future mutually condition each other, eliminating the arrow of causality at the quantum level. This might resolve the “grandfather paradox” by making all histories consistent.
Shared unitary as a time crystal – the unitary Ushared could be periodically applied, creating a self‑sustaining loop of negative energy that never decays (a “time crystal” of exotic matter).
Experimental signature – in a simulated P‑CTC using postselected photons, one should observe correlated negative energy densities at two spacetime points that are space‑like separated but linked by a CTC. This would appear as a violation of the quantum inequality at both locations simultaneously, which cannot be explained by independent local effects.
6. Relation to Earlier Speculations
Speculation #1 (future‑sourced negative energy) is a special case where Bob’s negative energy is zero and only Alice’s is non‑zero (or vice versa).
Speculation #2 (negative‑time photons) could supply the physical mechanism for the “hint” transmission if group delays become genuine retrocausal channels—but that remains unproven.
Speculation #3 is therefore a symmetric generalization that maximally exploits the P‑CTC framework.
7. Open Questions & Limitations
Self‑consistency: Does a solution for Utotal exist that yields negative energy at both ends? Likely yes for certain field configurations, but uniqueness is not guaranteed.
Probability: Postselection discards most runs. The probability of obtaining a run where both Alice and Bob get negative energy may be the product of two low probabilities, making experimental realization astronomically rare unless the P‑CTC amplifies it.
Energy conservation: Sum of negative energy at Alice and Bob might be balanced by positive energy elsewhere (e.g., in the quantum field’s vacuum fluctuations). This is consistent with QET.
Causality: No signal can be sent faster than light outside the CTC, but inside the loop causality is circular. This is acceptable for a self‑consistent block‑universe view.
8. Conclusion
Speculation #3 – Symmetric Retrocausal Energy Teleportation (SRET) – proposes that a closed timelike curve with postselection can generate negative energy densities at both the past and future ends of an entangled channel. The two local unitaries are derived from a shared, time‑symmetric global unitary, potentially allowing a wormhole or super‑entangled spacetime structure to be stabilized from both ends simultaneously.
While far beyond current experimental reach, SRET provides a coherent logical extension of P‑CTC + QET ideas, and it answers the question raised in our dialogue: “Could both Alice and Bob get negative energy? And could their unitaries be one and the same?”
Speculation #3 invites further inquiry:
If the shared unitary is also retrocausally determined, does it imply that negative energy is a boundary condition of the universe rather than a local violation of energy conditions? And could such a mechanism already be at play in the quantum vacuum’s hidden structure?

Proteins Double as Qubits: A Step That Could One Day Bridge Quantum Computing and Biology
Researchers recently tested a long-standing theory, and the results surprised them. Scientists at Washington State University developed a fluid that behaves as though it has negative mass. In practical terms, this means that when pushed in one direction, the fluid moves in the opposite direction—essentially flipping the normal rules of motion.
To create this effect, rubidium atoms were cooled to near absolute zero, forming a Bose-Einstein condensate—a unique state of matter where particles move in sync and behave as a single wave. The team used lasers to trap the atoms and adjusted their spin using another set of beams, forcing the condensate into a condition that mimicked the behavior of negative mass.
Additionally, experiments have provided evidence of 'negative time'—in which photons appear to exit a material before they enter it, suggesting a possible observational effect where time behaves unconventionally.

Abstract
The unification of gravity and quantum mechanics remains one of the most profound open questions in science. With recent advances in quantum technology, an experimental idea first proposed by Richard Feynman1 is now regarded as a promising route to testing this unification for the first time. The experiment involves placing a massive object in a quantum superposition of two locations and letting it gravitationally interact with another mass. If the two objects subsequently become entangled, this is considered unambiguous evidence that gravity obeys the laws of quantum mechanics. This conclusion derives from theorems that treat a classical gravitational interaction as a local interaction capable of transmitting only classical, not quantum, information2,3,4,5,6,7,8. Here we extend the description of matter used in these theorems to the full framework of quantum field theory, finding that theories with classical gravity can then transmit quantum information and, thus, generate entanglement through physical, local processes. The effect scales differently to that predicted by theories of quantum gravity, and so it gives information on the parameters and form of the experiment required to robustly provide evidence for the quantum nature of gravity.

Physicists create 'negative mass'
by Eric Sorensen, Washington State University
https://phys.org/news/2017-04-physicists-negative-mass.html
Washington State University physicists have created a fluid with negative mass, which is exactly what it sounds like. Push it, and unlike every physical object in the world we know, it doesn't accelerate in the direction it was pushed. It accelerates backwards.
The phenomenon is rarely created in laboratory conditions and can be used to explore some of the more challenging concepts of the cosmos, said Michael Forbes, a WSU assistant professor of physics and astronomy and an affiliate assistant professor at the University of Washington. The research appears today in the journal Physical Review Letters, where it is featured as an "Editor's Suggestion."

Fractal Instant (Zero D) Time (1D) Fields (2D) Parabolic Space (3D) Intersecting parabolas in 3D space
What if each instant transmutes into a fractal, or into less or more infinite instances? Time could then be understood as a figurative force moving one-dimensionally, enabling the fundamental fields—gravitic, strong, weak, and electromagnetic—to exist inherently as two-dimensional. An instance itself could serve as a unit to measure time and time dilations, yet a paradox arises: how can we measure the past, with respect to those dilations, using a time that only moves toward the future? Because each instant is composed of infinite instances, fewer instances correspond to a point in space, while more instances give rise to the expanding universe. The fields can only interact at a single instant—an infinitely small point—so they must be parabolic, thereby generating height, width, and volume. In this framework, experiments involving negative time provide the figurative ruler needed to determine how much negative energy density is required to establish a traversable wormhole.
What if time dilations are what's holding back the discovery of an advanced form of quantum entanglement? If you created a traversable wormhole, there would be some sort of slight paradox: how would one traverse from a region of space dilated such that its clock speed is faster, to a region of space that has a slower clock speed, without time traveling? There would be some sort of instantaneous spacetime where you would have to cross the dilation, and because we are assuming the speed of light is not the ultimate limit, we can say this is a paradox. Could one use negative energy to create regions of negative gravity that balance out Alice's and Bob's time dilation? Could the ruler used to measure the time dilations be negative-time experiments?
