She has become increasingly interested, too, in the end of the universe. Public engagement and advocacy Mack maintains a strong science outreach presence on both social and traditional media. She has been described by Motherboard and Creative Cultivate as a "social media celebrity". Mack is a popular science writer, and has contributed to The Guardian, Scientific American, Slate, The Conversation, Sky & Telescope, Gizmodo, Time and Cosmos, as well as providing expert information to the BBC. Mack's Twitter account has over 300,000 followers; her response to a climate change denier on that platform gained mainstream coverage, as did her "Chirp for LIGO" upon the first detection of gravitational waves. She was the 2017 Australian Institute of Physics Women in Physics lecturer, in which capacity she spent three weeks delivering talks at schools and universities across Australia. In 2018, Mack was chosen to be one of the judges for Nature magazine's newly founded Nature Research Awards for Inspiring Science and Innovating Science. In February 2019 Mack appeared in an episode of The Jodcast, talking about her work and science communication. Mack was a member of the jury for the Alfred P. Sloan Prize in the 2019 Sundance Film Festival. In 2019, she was referenced on the Hozier track 'No Plan' from his album Wasteland, Baby!: "As Mack explained, there will be darkness again". She is a member of the Sloan Science & Film community, where she works on science fiction. Her first book, The End of Everything (Astrophysically Speaking), was published by Simon & Schuster in August 2020, the firm having won the rights to Mack's first book in an eight-way bidding battle. It considers the five scenarios for the end of universe (both theoretically and practically), and has received positive reviews both for its science outreach accuracy and its wit. The book is also a New York Times Notable Book and features on the best books of the year lists of The Washington Post, The Economist, New Scientist, Publishers Weekly, and The Guardian. Personal life Mack is interested in the intersection of art, poetry and science. She is bisexual.
