háorkugeislun
Háorkugeislun is a hypothetical phenomenon theorized in speculative physics. The term itself is derived from elements suggesting "ancient light" or "primordial radiation." The core concept revolves around the idea that an extremely faint and pervasive form of electromagnetic radiation might exist, originating from the very early universe, even predating the cosmic microwave background (CMB). Unlike the CMB, which is primarily composed of photons from the epoch of recombination, háorkugeislun is proposed to be a relic from an even earlier, possibly inflationary, epoch.
The proposed characteristics of háorkugeislun include an extremely low energy density and a broad, non-thermal spectrum.
