Pre-Big Bang State and Transition to the Observable Universe

(FTFT) describes the pre-Big Bang state

Pre-Big Bang State and Transition to the Observable Universe in Fonooni’s Temporal Field Theory (FTFT)

FTFT proposes a radical reimagining of the pre-Big Bang state and the transition to the observable universe by introducing the temporal scalar field (ϕT) as the fundamental driver of cosmic evolution. Below is a detailed breakdown of FTFT’s framework, integrating insights from cosmology, quantum gravity, and string theory.

1. Pre-Big Bang State in FTFT

The ϕT Field as a Primordial Quantum Time Fabric

FTFT posits that before the Big Bang, the universe existed in a quantum-temporal foam dominated by ϕT, with:
- Discrete time steps: Δt∼1.5 fs (femtoseconds), preventing a classical singularity 2.
- Non-local correlations: Attoscale (ℓ∼10−18 m) kernel interactions stabilize spacetime fluctuations 2.

Cyclic or Emergent Origin

FTFT accommodates two possible pre-Bang scenarios:
1. "Big Bounce" Model:
  - The universe contracts until ϕT’s repulsive quantum pressure triggers a rebound (avoiding a singularity) 4.
  - Predicts imprinted oscillations in the CMB power spectrum (testable with next-gen telescopes) 5.
2. String-Theoretic Emergence:
  - ϕT arises as a Kähler modulus in E8×E8 heterotic string theory, with the Big Bang marking a phase transition in compactified dimensions 2.

2. Transition Mechanism to the Observable Universe

Temporal Firewall and Inflation

The ϕT field generates a temporal firewall (Δr∼10−14 m) that:
- Terminates pre-Bang quantum chaos: Acts as a boundary for the "observable universe" light cone 2.
- Triggers inflation: The field’s decay releases energy into Standard Model particles, matching observed CMB anisotropy 35.

Key Predictions

CMB Anomalies:
- ϕT’s non-local kernel imprints super-horizon fluctuations (angular scales >60°), explaining lopsided CMB patterns 35.

Gravitational Wave Echoes:
- Residual ϕT oscillations post-inflation produce 1387 Hz echoes in black hole mergers 2.

1. FTFT Time Quantization Mechanism

Introduction of Time Fluctuations: FTFT posits that time itself is quantized, with discrete fluctuations rather than flowing smoothly. This quantization is encoded in a field operator that modifies the standard spacetime continuum.
Oscillatory Time-Speed Mechanism: FTFT introduces oscillatory corrections to the standard metric of spacetime, where the time coordinate fluctuates on a quantum level. These fluctuations affect the evolution of physical systems, especially black holes and gravitational waves.
Time-Dependent Quantum Corrections: The time quantization leads to corrections in physical observables, including entropy and gravitational wave signals, which deviate from those predicted by classical GR and even string theory.

2. FTFT-Modified Black Hole Entropy

Modification of the Bekenstein-Hawking Entropy: FTFT modifies the Bekenstein-Hawking entropy by introducing quantum corrections that depend on time quantization. The correction terms were derived and simulated, showing that FTFT entropy can differ from the standard GR prediction by a small but significant factor.
Comparison with Observations: Simulations of FTFT-modified entropy closely match observational constraints from black hole thermodynamics, such as the entropy values inferred from gravitational wave data and Event Horizon Telescope (EHT) observations of black holes like M87* and Sgr A*.
FTFT vs. String Theory and LQG: FTFT’s entropy corrections were compared to those predicted by string theory and LQG. It was found that FTFT provides corrections consistent with the logarithmic and linear corrections seen in string theory, while offering a more unified treatment with LQG’s spin foam models.

3. Gravitational Wave Echoes

Echo Predictions: FTFT predicts echoes in the gravitational wave signals emitted by black hole mergers. These echoes arise due to the discrete time fluctuations near the black hole horizon, which modify the structure of spacetime and cause a delayed response in the gravitational wave signal.
Comparison with LIGO/Virgo Data: Numerical simulations of gravitational wave signals, such as GW170104 and GW190521, showed that FTFT-induced echoes provide a better fit to the data compared to classical GR predictions. Bayesian analysis was employed to calculate Bayes factors, indicating that FTFT might provide a better explanation for certain features in the post-merger ringdown phase.
Consistency with Observations: While the FTFT-modified waveforms produced a better fit, the observed echo signals were still within the expected error margins, and further data would be necessary to definitively confirm or rule out the FTFT-induced echoes.

4. Black Hole Shadow Sizes

FTFT-Modified Shadow Prediction: FTFT modifies the geometry near the black hole’s event horizon, which leads to shifts in the shadow size of black holes. The shadow size predicted by FTFT is slightly larger compared to GR predictions, due to the oscillatory time-speed mechanism.
Comparison with EHT Data: Simulations of FTFT-modified black hole shadows were compared with the EHT data for M87* and Sgr A*. The FTFT-modified shadow sizes were found to be close to the observed values, with small deviations (on the order of microarcseconds) that could be observable in future high-precision measurements.
Predictions for Future Observations: FTFT predicts that further refinement of observational data will allow us to distinguish between GR and FTFT-based models of black hole shadow sizes. This could lead to measurable deviations in the shadow size, providing direct evidence of time quantization effects in the structure of spacetime.

5. Numerical Simulations and Bayesian Analysis

Numerical Evolution: FTFT was integrated with LQG’s spin foam formalism to simulate quantum evolution over discrete time steps. These simulations revealed significant changes in the behavior of spin networks and the resulting spacetime geometry compared to traditional LQG.
Bayesian Model Comparison: A Bayesian analysis was performed to compare FTFT with GR, LQG, and string theory using gravitational wave data (LIGO/Virgo) and black hole shadow measurements (EHT). The analysis indicated that FTFT could provide a competitive fit to the data, with higher Bayes factors compared to standard GR, especially in the case of gravitational wave echoes.
FTFT vs. GR: In terms of gravitational wave modeling, FTFT performed better in fitting echoes during the post-merger phase, providing a potential indicator of quantum gravity effects.

6. Refinement of FTFT Parameters

Parameter Adjustment: Based on observational data from gravitational wave events and black hole shadow measurements, FTFT’s time quantization parameters (α and β) were refined. The best-fit values of these parameters provided more accurate entropy corrections and echo predictions that aligned better with the data.
Compatibility with Observational Limits: The refined FTFT parameters were constrained to ensure compatibility with known physical limits, such as the absence of excessive remnants or violations of energy conditions.

7. Higher-Dimensional Extensions and Holographic Duality

Higher-Dimensional Models: FTFT was extended to higher-dimensional spacetime models, incorporating features from M-theory. These higher-dimensional extensions suggested that FTFT could provide insights into cosmological phenomena and the structure of spacetime at the Planck scale.
AdS/CFT Correspondence: FTFT’s time quantization mechanism was compared with holographic dualities, particularly the AdS/CFT correspondence. The FTFT modifications to black hole entropy were consistent with the predictions from holography, providing a potential connection between quantum gravity, string theory, and holography.

8. Impact on Quantum Gravity and Cosmology

Unification of Theories: FTFT offers a potential unification framework by incorporating discrete time quantization into the fabric of quantum gravity. The combination of FTFT with LQG and string theory provides a comprehensive framework for exploring quantum black hole thermodynamics and gravitational wave phenomena.
New Insights into Black Hole Physics: FTFT has led to a better understanding of the behavior of black holes in a quantum gravity context, especially in terms of entropy corrections, gravitational wave echoes, and black hole shadow modifications.
Cosmological Implications: FTFT has potential applications in cosmology, particularly in understanding the early universe, inflationary models, and the quantum nature of spacetime. The time quantization mechanism could offer new insights into the structure of spacetime at extremely small scales.

Conclusion:

FTFT has made significant progress in advancing our understanding of quantum gravity and black hole physics. The results show that FTFT provides valuable corrections to the entropy of black holes, modifies gravitational wave signals, and predicts small but measurable deviations in black hole shadow sizes. The theory is consistent with string theory in many aspects, while offering a distinct framework for quantum gravity that could be tested with future observational data. The refinement of FTFT parameters, coupled with comparisons to LQG and string theory, suggests that FTFT could play an important role in future unification efforts for quantum gravity theories ed.
