The "Quantum-Geometry Dynamics (an axiomatic approach to physics)" book presents a theory (QGD) that has a distinct perspective on gravity and related phenomena, including what might be interpreted as gravitational waves.
•
QGD Precludes Gravitational Waves: According to QGD, gravitational waves do not exist. Instead, the signals detected by the LIGO-Virgo observatories, which are consistent with the gravitational waves predicted by general relativity, are proposed to have a different nature.
•
Preonic Waves as an Alternative: QGD suggests that the signals detected by LIGO-Virgo could be composed of polarized preons (the fundamental quanta of space in QGD) resulting from the polarization of large regions of the preonic field by coalescing binary systems, or by dark photons. The mechanism of preonic field polarization is discussed in the context of electromagnetic effects in QGD.
•
Polarization Mechanism: In QGD, polarizing particles or structures (analogous to charged particles in standard physics) interact with the preonic field (composed of free preons), causing it to become polarized. The intensity of this polarization, or magnetic moment, is proportional to the angular spin momentum of the particle and the density of the preonic field. For a binary system, as the stars accelerate towards each other, they become increasingly polarizing, leading to a wave-like variation in the polarization of the neighboring preonic field.
•
Distinguishing Preonic Waves from Gravitational Waves: QGD proposes that preonic waves could impart momentum to the mirrors of the LIGO-Virgo detectors, similar to how magnetic fields interact with matter. The variations in frequency and magnitude of these preonic waves, resulting from the dynamics of the coalescing bodies, would be similar to those predicted for gravitational waves by general relativity, making them observationally difficult to distinguish. QGD suggests that new experiments and instruments might be needed to differentiate between these two interpretations.
•
QGD Cosmogony and the Preonic Universe: QGD's cosmological model starts with an initial state where only free preons (+) existed and were homogeneously distributed throughout quantum-geometrical space. This is termed the preonic universe. In this initial phase, the n-gravity (repulsive force between space preons (-)) and p-gravity (attractive force between matter preons (+)) fields were in perfect equilibrium. Over time, due to p-gravity, preons (+) condensed to form particles, starting with neutrinos and then photons, which eventually formed the cosmic microwave background radiation (CMBR). The observed isotropy of the CMBR is a consequence of the initial isotropic distribution of preons (+).
•
Dark Matter and Dark Energy in QGD: QGD attributes the effects of dark matter to interactions between light and material structures with regions of space where free preons (+) have condensed (dark matter halos). The dark energy effect is suggested to be related to the jets of preons (+) and neutrinos radiated from black holes
•
Implications for Cosmology: The QGD perspective alters the understanding of cosmological phenomena like redshift. QGD predicts an intrinsic gravitational redshift at the source itself, caused by gravitational acceleration, which contributes to the observed cosmological redshift, along with the Doppler effect. This explanation does not require the expansion of space in the same way as some interpretations of general relativity. Repulsive gravity at cosmological scales (between structures separated by distances greater than a threshold dΛ) also contributes to the large-scale structure and recession speeds of galaxies.
The "New DESI Results Strengthen Hints That Dark Energy May Evolve" article focuses on observations within the standard cosmological model. It discusses how the Dark Energy Spectroscopic Instrument (DESI) data, combined with other cosmological observations, suggests that dark energy's influence might change over time, which is QGD cosmological model and description of gravity implies.
In summary, the QGD framework, as presented in Quantum-Geometry Dynamics; an axiomatic approach to physics, offers an alternative explanation for the phenomena attributed to gravitational waves, suggesting they might be preonic waves arising from the polarization of the preonic field. This concept is embedded within a broader cosmological model that posits a preonic universe as its origin and offers alternative interpretations for dark matter, dark energy, and cosmological redshift, differing significantly from the standard cosmological model discussed in another source.
