Relativistic Frequency Shifts and Higher-Dimensional Effects: A Theoretical Extension of D'Abramo's Observations

Description:D’Abramo (2022) identified non-Doppler frequency shifts in electromagnetic waves over astronomical distances, suggesting a novel relativistic mechanism. This study extends these findings with a five-dimensional (5D) spacetime model, where time dilation from velocity or gravity influences light propagation. Building on our prior work \cite{Masarratbakhsh2025}, we propose that frame-dependent effects modulate both frequency shifts and wave-particle duality, offering a unified explanation consistent with muon data and testable via slit experiments. Incorporating Reich’s (2023) frame-dependent constants, this model explores implications for cosmic redshift and the black hole information paradox. Presented as a preprint, it invites feedback and aims for peer-reviewed publication to advance relativistic and quantum theory. Keywords: Five-dimensional spacetime, relativistic frequency shifts, wave-particle duality, time dilation, black hole information paradox, astrophysics, quantum mechanics Type: Article (Preprint) Authors: Bahman Masarrat Email: [email protected]
