Anti-gravity technology is a theme in many works of science fiction, and a hope for those who dream of radical engineering breakthroughs. It is also, I have learned, a topic of serious study in a segment of the scientific community. I recently interviewed Gregory Daigle, author of a newly released book Gravity 2.0: Design Strategies for a Gravity Modified World to learn more about the field... FET: What made you focus on the design aspect of modification of gravity? GD: If gravity-like fields, both attractive and repulsive, can be produced along the lines proposed by Extended Heim Theory (EHT) then...
