This simply goes beyond anything I could've possibly imagined:

"The European Space Agency explains that the galaxy contains a supermassive black hole that has 21 billion times the mass of the Sun and an event horizon — the surface at which even light cannot escape its gravitational grasp — of approximately 81 billion miles. That makes the event horizon about 15 times the diameter of Neptune’s orbit from the Sun."

Carl Segan commented on the concept of numerous. The universe has such large numbers in so many places that we have trouble wrapping our heads around it. Doesn't stop man from trying though.
