Black Mass: Cygnus X-1


{ Liturgy for a black hole }


Known as the celestial swan, the constellation Cygnus has been the source of myth since the Neolithic era. Many ancient monuments of worship were built aligned to its coordinates, as it lays to the north, near the summer solstice.

Cygnus X-1 is a black hole, located in the Cygnus constellation. It was first observed 1964 as one of the strongest X-ray sources that could be seen in space, and was identified as a black hole because of its relationship to the star HDE 226868.

Cygnus X-1 and HDE 226868 orbit each other forming a high-mass X-ray binary, where the star is visible by the emission of light, while the black hole is the dominant source of X-rays.

The Noise of Closed-Eye Vision





In a darkened room, or with your eyes closed, you may have experienced the noise of closed-eye vision. The phenomenon of closed-eye hallucinations, or a phosphene, is the perceived sensation of seeing light, when no light is actually entering the eye.

There is form in the indistinguishability of dark events.

Even in the absence of light, some impulses are still sent along the optic nerve, causing the sensation of an animated, dark coloured noise.
