Looking at a black hole, A new way of seeing.
On 10 th April 2019, the first ever image of a black hole was published by global media. A
black hole is a singularity of the space-time continuum, an object whose gravity is so large
that it traps light, forbidding it from returning to the vast outer space in the Universe.
With this image, a new paradigm of seeing has emerged. The image was the unlikely and
amazing outcome of a vast and incredibly sophisticated scientific collaboration called the Event Horizon Telescope,
which involved 200 scientists in 20 countries working together for
nearly a decade (Brian Resnick in Vox). This black hole whose image was captured by the
joint work of eight radio telescopes lies at the center of the Messier 87 galaxy. This black
hole is so vast that it has a mass of 6.5 billion suns and the force of its gravity propels jets
of plasma, moving at near the speed of light. One of the scientists who worked in the
team was Katie Bouman, the woman who coded the algorithm needed to reconstruct the
image of the black hole. Although with some differences in complexity, Bouman´s
algorithm is similar to the one that reconstructs the image of a human liver in an MRI
scan.
The thought
Seeing something used to be an experience involving the process visual stimuli of a special
place in the space around us, enters through our eyes and reaches the cortex in order for
our brain to build a representation of that something within the world. This process has
now become an intellectual, constructive, collective act and task where the image that
shall be seen needs to be incubated (for months, years) in order to emerge complete in
front of the eyes of the beholder. Is it possible to see this image and think, as the medieval
philosopher Aquinas thought, that the relations amongst the parts (of the images
collected by the radio telescopes) were at the end adjusted (with the aid of extremely
accurate atomic clocks) to such a special point as to make them appear as exquisite and,
eventually, showing humanity a path towards its soul? Might a collective epiphany have
enlightened the minds of a determined and passionate team of scientists when the image
of such an absolute nothingness was finally complete?
