A team of astronomers recently discovered the smallest black hole to date, which indicates that there may be far more out there than we previously thought.

An editorial "oops" in the Ohio State quote:

how supermassive black stars explode
My bold.

Mr. Williams made the following questionable remark:

One way to find them is to look for binary systems, where two stars are locked in orbit with each other due to their mutual gravity. When one of these stars dies, the intense gravitational pull it generates will begin to pull matter from the other star.
As I understand it, there is no need for a star to die first. It can pull matter from the other star anytime if the other star is expanding and overflowing its Roche lobe. Algol is a case in point.

Lapses like these make me question the reliability of these articles.
