Scientists are on the cusp of capturing the first-ever movie of a supermassive black hole in action, which could change our understanding of these enigmatic objects forever. The Event Horizon Telescope (EHT) project aims to track the colossal black hole at the heart of the Messier 87 galaxy and reveal its secrets.
For decades, black holes have been shrouded in mystery, often portrayed as cosmic villains that suck everything up without a second thought. However, experts argue that these objects are more fascinating than frightening, holding the key to understanding how the first galaxies emerged and evolved over time.
The EHT network of 12 radio telescopes will work together to capture a complete image of the black hole every three days throughout March and April as the Earth rotates. This painstaking process could yield stunning footage of the swirling disc that marks the edge of the event horizon, the point beyond which no light or matter can escape.
Measuring the black hole's spin speed is crucial because it could help scientists distinguish between different theories about how these objects grow in size and power. If black holes primarily accumulate material through accretion, they would likely be spinning at incredibly high speeds. On the other hand, if they expand mainly through mergers with other black holes, each merger would slow them down.
The observations could also shed light on how massive jets are formed, which are among the largest and most powerful structures produced by galaxies. These jets can hinder star formation within galaxies, leading to a slower growth rate. In turn, this can trigger bursts of star birth beyond the host galaxy.
While it's unlikely that scientists will see the black hole in action before summer due to the enormous volume of data generated by the telescopes, this groundbreaking research could fundamentally alter our understanding of these cosmic enigmas.
