It depends on the mass of the black hole. and what you are fitting the Earths into. Supermassive black holes range from about 1 million to 12 billion times the mass of the sun (330 billion to 4 quadrillion Earth masses). The mass of any black hole is contained in a singularity that has zero volume. The radius of the event horizon is directly proportional to the mass and so the volume is proportional to the cube of the mass. A 1 million solar mass black hole would have an event horizon about 5.9 million kilometers (3.6 million miles) in diameter or with a volume of 200 quintillion cubic miles. Such a volume would fit about 100 million Earths The black hole at the center of our galaxy is 4 million solar masses, which would fit about 6.4 billion Earths. A 12 billion solar mass black hole would fit about 1.7 quintillion Earth volumes in its event horizon.

After "Crisis on Infinite Earths," the DC Universe was restructured with a single Earth and timeline. This event simplified the continuity and history of the DC characters, leading to a new era of storytelling that became known as the post-Crisis era. Many characters were rebooted, origins were retold, and new storylines were introduced to reflect the changes made by the event.
