Tom 618: A Cosmic Monster

Overview of Tom 618

• Tom 618 is one of the largest and most massive black holes discovered, located approximately 18 billion light-years from Earth.

• It has a mass around 66 billion times that of the Sun, making it an extraordinary cosmic entity.

• The event horizon of Tom 618 measures about 390 billion kilometers in diameter, which is over 40 times the distance from the Sun to Neptune.

Quasar Activity

• Tom 618 powers an extremely bright quasar due to vast amounts of matter falling into it.

• As this matter forms a superheated disk around the black hole, it releases immense energy, resulting in significant luminosity.

• The brightness of this quasar surpasses that of its host galaxy, complicating detailed observations of the galaxy itself.

Implications of Light Travel Time

• The light we observe from Tom 618 today left it billions of years ago, meaning its current state could be even more massive than what we see now.

• This suggests that Tom 618 may have consumed additional matter over time, potentially increasing its size beyond current estimates.
