In this article I’m going to delve into some of the science behind the exploration aspects of Clean Space, and perhaps tackle a couple misconceptions that you and I may share, such as the title of this article. Nothing I’m presenting here is ground-breaking, but I hope you find some of the facts interesting as we recap ourselves on those awful trigonometry lessons or physics classes of your past! Don’t be put off, I literally had no formal education beyond Secondary School in the UK (10th grade - or sophomore I believe it’s called - in the US), so there should be nothing here most layman can’t grasp. I’ll apologise now, because that same education (or lack thereof) will no doubt account for some level of ignorance and subsequent mistakes in this article; if the actual smart people fancy lending me some pointers in the comments section, I’d be very grateful!
