Is gravity real?
If the world over the past 50 years was a science fiction novel, now would be a kairos for the emergence of gravitic technology in our society. If this was a speculative sci fi novel , we'd be discovering a technology that would change the game and help us to either save our abandon our planet in the next 10 years. That probably won't happen. But I'm just saying. Now would be the time for something like a fusion drive or a gravity drive. As kim stanley robinson so acutely asserted in his book, 2312, "Earth is a development sink".
