My choice of the word, mislead, was not appropriate to what I was intending to convey. It was a poor choice. For his sentence,
The black hole is enormous, with a radius of roughly 9 billion miles...
I was thinking the following when reading the sentence:
This statement will have most readers incorrectly assuming that a black hole would have an actual radius of 9 billion miles.
Here's the preceding paragraph; perhaps it will modify your assumptions?
On April 10, astronomers working with the Event Horizon Telescope unveiled a “photograph” of the monstrous black hole that sits at the center of the M87 galaxy, 54 million light years away. Viewed simply as an image, it is neither impressive nor straightforward: It presents a sort of nondescript, blurry, half-glazed doughnut, showing not the black hole itself but the shadow-like distortion it carves in the surrounding illumination. Yet, to a thinking mind, the image reflects the glory of understanding, and to an alert imagination it opens new portals into space, time and deep history.
The making of the image was a tour de force of science and technology. The black hole is enormous, with a radius of roughly 9 billion miles (or one hundred times the distance from the Earth to the sun) and a mass equivalent to two quadrillion Earths.
Wilczek even lived in Einstein's house!
For years!
Very smart guy.
