In the 1920's, soon after Einstein proposed his new theory of gravity, theoretical physicists realized that this theory predicted the existence of esoteric astrophysical objects they called black holes. These are collapsed massive stars which warp time and space around them as much as they skew human imagination... Black holes push our understanding of the material world, of time, and of consciousness to its limits, driving physics into the realm of philosophy. In the past few years, we have discovered billions and billions of black holes all around us, scattered across the universe. We now know that these violent, extraordinary entities play a key role in the evolution of the universe, and of life... To understand black holes we need to go beyond traditional physics towards crazy ideas of string theory, but also those of Ancient Greek philosophy. Looking at recent photos of black holes we will discuss these strange entities and their philosophical significance.
