The first three issues of Worlds of IF science fiction since the revival by Starship Sloane Publishing. They look good in print!

Each issue has a story by me: "Our Place on the Map of the Universe", "From Deep Darkness came Murmurs of Awakening", and "A Three-Dimensional Chessboard Universe"

It's Stephen Hawking's birthday. The occasion to share this fantastic video he produced as part of his Genius documentatry series. Hawking elaborates on our place in the Universe, including our membership to the Laniakea supercluster of galaxies that we discovered back in 2014.
