First an honest question, then a shameful piece of self promotion.
The question is in multiple parts: What do you feel is the most dramatic scientific discovery of the past hundred years; the past ten years; and what are your prediction of the most dramatic in the next ten years; the next hundred?
OK, now for the shamefulness. I am posting to involve readers in my future-based sci fi novel that I plan to market to agents and publishers. The means I am trying to involve those readers is by carefully rendering a "future timeline," which serves as the background or foundation for that novel. My details are of course pure, idle speculation, but as for the science I am attempting some credibility. For instance in a post I will be making in a few days, I explore terra-forming to resolve over-population, further I will say the terraforming involves the use of cosmic radiation and can be expeditated by an Iodine isotope that is not currently stable. A scientist may look at all of this as absolutely ... , but while the means I say may or may not be ludicious, the idea is interesting. Since my intended reader is young adult, I hope it could inspire an interest in science. My site, to finish this sales pitch, is:
