@thefaico This is how science works: You make your experiments, and you want the other scientists to know your results (because otherways science does not go forward!). You need a peer-reviewed scientific journal (possibly of high impact). In fact peer-reviewed journals are basically the only "acceptable" way to publish for scientists. "Peer review" means that the journal asks other scientists (something like 3 or 4) to review your work, comment and decide if your article good to publish. I have reviewed some articles and it takes something between a few hours to a few days (depending on the complexity)... reviewers don't get paid. But that's not all, most journals belong to big publishing groups (such Elsevier, Wiley, Cell...) so they ask reputable scientists to be the editors of specific journals... and usually they don't get paid either (just do it for the CV). Finally, the article is downloable for between 18 to 40$ and a net revenue of 30% or more for the company !science !nature
