Black Hole research that led to this discovery is fascinating and bodes well for future studies.

It is mind-boggling to even try to imagine the size of this particular Black Hole.

Thank you for the link Frank :icon-smile:

Hi Frank. This is a very informative and interesting link. Gravitational lensing has been used for a couple of years now, but this is a "big" discovery. Thanks for finding and sharing this link with us Frank, but lately when I hear "black hole" it makes me think of our bank account. :lol:

That's interesting, it is 1700 times larger in diameter - volume wise 5 billion suns - but weight wise only 30 Suns. That is totally weird.

Speaking of scales, I was just reading that in 2016 there were an estimated 2 trillion galaxies based on Hubble observations but that was revised downward by a factor 10 in 2021 after New Horizons discovered that the background UV radiation outside the solar system is 10 times less. Oops.

The average galaxy has an estimated 100 million stars so that black hole has consumed 300 galaxies, star-wise. Assuming that the Sun is an average star, which I believe it is.
