Pursuing further our work on Born Reciprocal (Non-inertial) Relativity theory we find that the family of hyperbolic trajectories of particles living in a four-dim phase space of signature $ (2,2)$ automatically satisfy the maximal speed of light and the maximal proper force conditions. A direct link between the maximal proper force $ b $ and the minimum value of the initial positions $ (x_o)_{min}$ of these hyperbolic paths is found. Furthermore, when the maximal proper force is set to be equal to the Planck-mass squared $ b = m_P^2$ then $ (x_o)_{min} = 2 G {cal M } $ happens to coincide with the numerical value of the horizon radius of the Schwarzschild black hole in four spacetime dimensions. We proceed with a rigorous analysis of how open strings sweeping a two-dim world-sheet region inside a Rindler wedge in a $ D = 1 + 1 $ spacetime can be seen as a continuum of point masses that are being collectively accelerated along the Rindler hyperbolic trajectories. The upshot of this analysis reveals that these strings can naturally acquire a $variable$ tension which is consistent with the dynamical tension model of strings and branes proposed by Guendelman in the past years cite{Eduardo}. We finalize by analyzing strings moving in phase space backgrounds within the context of non-inertial relativity theory.

The Gravitationally Active Spacetime Curtain (GASC), a unified framework is proposed where spacetime itself acts as a dynamic medium endowed with tension, a compressible root fluid, and repulsive anti-gravitons. This approach naturally resolves three fundamental problems in modern physics: black hole singularities transition to stable dark planets with finite-density cores, dark matter emerges from spacetime's density variations without requiring new particles, and quantum gravity becomes testable through anti-graviton-mediated interactions. The theory provides solutions for black hole structure, reproduces observed galactic rotation curves, and matches gravitational wave data from LIGO while predicting distinctive late-time echoes. Crucially, GASC makes testable predictions across multiple scales - from gravitational wave detectors like LISA, which could detect characteristic merger echoes, to particle colliders where missing-energy events would signal anti-graviton production. Unlike string theory or conventional dark matter models, GASC offers direct experimental verification through near-future observations while maintaining mathematical consistency with general relativity and quantum field theory. The framework presents a compelling alternative to current paradigms by unifying gravity, quantum effects, and dark phenomena through spacetime's intrinsic properties rather than hypothetical entities, bridging the gap between theoretical elegance and empirical testability.

Gravitational waves with frequencies above 50 Hz propagate at the speed of light. To date, there have been no measurements at lower frequencies. Analyses show that records of the atmospheric pressure at significantly lower frequencies contain signals from extraterrestrial sources. These are phase-modulated, and the propagation speed depends on the frequency. If the waves are GW, the measurements could confirm the existence of gravitons and allow a mass determination. The results of previous work are summarized here.

This article proposes a deterministic foundation for quantum mechanics and spacetime based on a Unified Dynamic Network Theory (UDNT), in which nodes and links form the sole constituents of physical reality. Space, matter, and time are not independent entities but emergent aspects of the same underlying network dynamics. Nodes undergo continuous join—split cycles, producing the intrinsic oscillatory behavior normally attributed to zero-point fluctuations. Distance is defined by the typical number of network transitions between two regions rather than by pre-existing geometric separation. Phases attached to the network links enable multiple microscopic paths to coexist, providing a deterministic mechanism for superposition, interference, and wave-like behavior. Spin is incorporated through a minimal two-component internal structure of the link phases.Matter arises as a stable pattern of enhanced connectivity that retains its identity under the network’s evolution. In this way, space and matter are unified: particles are excitations of the same relational structure that constitutes the geometry around them. Such excitations naturally modify the surrounding network, suggesting a path toward a geometric description of gravitation. Quantum entanglement is reinterpreted as the presence of direct nonlocal connections that impose correlations without transmitting signals through space. In this framework, quantum randomness is not fundamental but emerges from the complexity of the network’s deterministic evolution. The UDNT approach thus offers a coherent relational picture in which spacetime, matter, and quantum phenomena jointly arise from a single, evolving network substrate.

We investigate the wave function of the universe near the Big Bang Singularityin three dimensions. The Wheeler-DeWitt equation in the minisuperspace model issolved to obtain a wave function of the universe in Anti-deSitter space (cosmologicalconstant :Λ < 0). In addition we speculate the case of TMG (Topologically MassiveGravity) Universe.
