The Dual Observation of Supernovae: Entangled Signal vs. Delayed Photon Detection – A Misinterpreted Evidence of Cosmic Expansion

Abstract This paper reinterprets the observation of Type Ia supernovae used as standard candles in cosmology. We show that the simultaneous arrival of supernova signals in space-based and ground-based telescopes — particularly during events like GW170817 — indicates the existence of an entangled information channel that delivers a "live" image of the cosmic event. In contrast, the traditional light signal, traveling at the speed of light, arrives billions of years later. The confusion between these two distinct observations has led to a misinterpretation of distant supernovae as evidence of accelerated cosmic expansion. We present a coherent framework under which entangled signals and light-based signals are treated distinctly, allowing for a correction of this cosmological misjudgment.
