Under this title, the publication "The Conversation" under its motto "Academic rigor, journalistic flair", presented an article written by the University Distinguished Professor of Astronomy of the University of Arizona CHRIS IMPEY, who --by the way-- is British.
The publication is from December 4, 2020, but has not lost a bit of its pertinence and validity.
That is why we recommend its reading.
