Making the invisible visible - The Painters Keys
”To sense the invisible and to be able to create it,” wrote Hans Hofmann, “that is art.” An English clergyman wrote a letter 235 years ago proposing the idea of a giant but invisible star so massive that it swallowed its own light. Based on his calculations, this body could be detected by its gravitational effect on surrounding objects. In 1915, 114 years later, Albert Einstein was developing his theory of general relativity, building upon his already proven theories about gravity’s influence on the motion of light. Then, in the 1950s, astronomers with radio telescopes noticed that seemingly peaceful galaxies were emitting disproportionate amounts of energy from their cores.
