 what is it that you personally would really like to investigate? And I thought, well, actually, an undiscussed technological breakthrough on the order of the atomic bomb from the Second World War. What would that breakthrough be, I thought? Well, I think it would be in the propulsion arena. And that said, I think it would therefore be in the kind of anti-gravity field. And I think that would be a secret you'd really want to hush up.
