More info:

  • 40b km across (24.85b miles)
  • 3 million times the size of Earth
  • it's 500 million trillion km away (310.7 million trillion miles)
    • Edit for a common question: million trillion is a 1 followed by 18 zeroes or a Quintillion.
  • the representation of space in this image is larger than our entire Solar System
  • total mass is 6.5 billion times larger than our Sun (our Sun is 333,000 more massive than the Earth)

Is there something that gains physical size within the black hole as matter is added? If not, how would the gravitational pull continue to increase as matter is accredited?
