David Brin is a scientist, inventor, and New York Times bestselling author. With books translated into 25 languages, he has won multiple Hugo, Nebula, and other awards. A film was based on David’s novel The Postman. In EARTH and EXISTENCE he explores near future trends that may transform our world. With degrees from Caltech and the University of California-San Diego, Dr. Brin serves on advisory panels ranging from astronomy and NASA’s NIAC program to others dealing with artificial intelligence, nanotech, SETI, national defense, and technological ethics. As a speaker and on television, David Brin shares unique insights – serious and humorous – about ways that changing technology may affect our future lives.

Dr. Gerald B. Cleaver earned his Ph.D. in early universe cosmology and string theory at Caltech in 1993. Cleaver is Professor and Graduate Program Director of the Department of Physics at Baylor University in Waco, Texas. He heads the Early Universe Cosmology and String Theory (EUCOS) Division of Baylor’s Center for Astrophysics, Space Physics and Engineering Research (CASPER).

Dr. Gerald Jackson received his doctorate in the field of accelerator physics from Cornell University, where he studied collisions between electrons and positrons. From 1985 until 2000 he was instrumental in improving the performance of the Fermilab proton-antiproton collider program through enhancements in the production, manipulation, and storage of antiprotons. Dr. Jackson was a leader in the design, construction, and commissioning of the innovative 2 – mile circumference antiproton Recycler ring, the last major particle physics accelerator built in the United States. Designed to increase Fermilab performance by 2.5X, the Recycler and other upgrades actually resulted in an increase of more than a factor of five. During his 14 years at Fermilab, he had been instrumentation department head, leader of Main Ring operations, and leader of many accelerator technology development projects. Since 2000 he has founded several companies, one working on antimatter propulsion problems for NASA and culminating in a 2016 crowdfunded study of antimatter production enhancements.

He currently lives Berea, Ohio with cats named Azrael and Tyrael, several teddy-bears, more books than you can count in a year, and no goldfish. He is married to science fiction writer Mary A. Turzillo.

Dr. Philip Lubin is a professor of Physics at UC Santa Barbara whose primary research has been focused on studies of the early universe in the millimeter wavelengths bands as well as applications of directed energy for planetary defense and relativistic propulsion. His group has designed, developed and fielded more than two dozen ground based and balloon borne missions and helped develop two major cosmology satellites. He is director of the NASA Starlight program, currently in a Phase II whose goal is to use directed energy for humanity’s first interstellar missions. He is also concept director for the Breakthrough Starshot program whose goals are also to achieve relativistic flight with miniature spacecraft . He is co-recipient of the 2006 Gruber Prize in Cosmology along with the COBE science team for their groundbreaking work in cosmology as well as the 2018 Gruber Prize in Cosmology along with the Planck science team for their determination of fundamental cosmological parameter.

Dr. Tracie Prater is an aerospace engineer in the Materials and Processes Laboratory at NASA Marshall Space Flight Center, where she is currently supports technical integration activities for the in-space manufacturing (ISM) project.

Dr. Deana L. Weibel is a Professor at Grand Valley State University in Allendale, Michigan, jointly appointed in the Department of Anthropology and the Department of Integrative, Religious and Intercultural Studies (IRIS). While most of her early work focused on religious pilgrimage and sacred places (such as Rocamadour, France and Chimayó, New Mexico), current work examines the religious perspectives of people involved in space exploration. A recent sabbatical involved ethnographic fieldwork at the NASA Human Research Investigators Workshop, the Kennedy Space Center, the Mojave Air and Space Port, the Jet Propulsion Laboratory and the Vatican Observatory. Weibel’s interview subjects have included engineers, astronauts, astronomers, test pilots and aerospace physicians, and her goal is to better understand how scientific and religious perspectives are separated and/or integrated among people whose work gives them expert knowledge about “the heavens”. Relevant publications include “Malinowski in Orbit: ‘Magical Thinking’ in Human Spaceflight” (with Glen E. Swanson), “Magnetism and Microwaves: Religion as Radiation,” “’Up in God’s Great Cathedral’: Evangelism, Astronauts, and the Seductiveness of Outer Space, ” and “Pennies from Heaven: Objects in the Use of Outer Space as Sacred Space.”
