Among the most unimaginable: "Two black holes most massive ever found, astronomers say" December 5, 2011 7:53 pm bowser

Check that event horizon.  Beyond human imagination.

“The mass of each is about 10 billion times the mass of our sun. The previous black hole record holder, first measured in 1977, has a mass of about 6 billion suns.

“And for each black hole, the “event horizon” – basically areas from which nothing can escape their gravity – is about five times the distance between our sun and Pluto.”

 

  • The "event horizons" on these are 5 times the distance from the Sun to Uranus. by bowser 2011-12-07 10:25:32
