The Largest Black Hole in the Universe - Size Comparison
Kurzgesagt – In a Nutshell・2 minutes read
Black holes, ranging from tiny Primordial Black Holes to Ultramassive Black Holes, are the largest entities in the universe, capable of continuous growth and various functions. Their existence and properties play a crucial role in understanding the structure and dynamics of galaxies, with Supermassive Black Holes like Sagittarius A Star and TON 618 being prime examples.
Insights
- Black holes vary in size, from tiny Primordial Black Holes to massive Ultramassive Black Holes like TON 618, highlighting the diverse range of these cosmic entities.
- Supermassive Black Holes, such as Sagittarius A Star, are common at the center of galaxies but do not solely dictate gravitational forces, as dark matter also significantly influences galactic dynamics.
