Black hole stars, a weird cosmic entity and Soundgarden song

18 December 2022

Black hole stars, sometimes called quasi-stars, were a hypothetical star that may have existed in the earliest days of the universe, up to about half a billion years after the Big Bang.

They were larger — far larger — than any star known to be present in the universe today, and were capable of outshining entire galaxies. And, as the name suggests, they were part black hole. We know some stars become black holes at the end of their lives, but for the two to somehow co-exist, star and black hole, without one destroying the other? How can such a thing even happen?

In 1927, British-Indian scientist J. B. S. Haldane, in an essay titled “Possible Worlds” wrote the oft quoted sentence: “now, my own suspicion is that the universe is not only queerer than we suppose, but queerer than we can suppose.” It was Haldane’s way of saying we’re unlikely to ever make sense of the universe, no matter how much we learn about it. Black hole stars, in their bizarre weirdness, only add to the wonder.

And, as a bonus, American rock/grunge act Soundgarden’s 1994 track, Black Hole Sun, written by the late Chris Cornell, takes on a whole (er, no pun intended) new meaning in this context.
