From Infinity to Infinity, 2025
The project From Infinity to Infinity traces the evolution of the coordinates of the star Spica from the past to the present.
Spica is the star that enabled the ancient astronomer Hipparchus to discover the phenomenon of precession.
One striking aspect of analyzing the Abbadia Observatory’s star catalogues is that new coordinates were always derived from previous reference coordinates.
This process demonstrates that scientific knowledge—and by extension, human knowledge—is not fixed, but fluid, constantly evolving through continuity.
It was long believed that humanity’s first star catalogue had been compiled by Hipparchus around 128 BCE.
This hypothesis was confirmed in 2022, when Hipparchus’s observations were discovered hidden within the Codex Climaci Rescriptus at Saint Catherine’s Monastery on the Sinai Peninsula, Egypt.
Much later, in 1989, the European Space Agency launched the Hipparcos satellite into space.
It recorded more than one million stars and produced the Hipparcos Catalogue, which formed the foundation of the current International Celestial Reference System (ICRS).
The Greek philosopher Heraclitus wrote, “Panta rhei — everything flows.”
Like water, stars also flow.
Within this vast current of change, traces of the past persist in the present, and the present continues into the future.
