Have you ever had an untested idea, which could be right or wrong, written meticulously about it on a webpage article and then have that page replaced by another purportedly back dated? It happened to me quite curiously. I'm sure of it because the posting service the webpage provided allowed for the user to re-edit the comment which I did several times revisiting the page. Then one day, after a couple of weeks I visited the webpage again to see whether anyone had commented on my post and hey presto, the page had been replaced by an older article, replacing the recent one.
The original article had prompted me to come up with an unrelated idea which even if it were wrong, how strange that the whole webpage had been replaced. The lesson is, always make a back up copy of whatever you write so if the webpage disappears for whatever reason, be it malign or benign, you have a record. Its happened to me twice on matter related to outer space but I kept a record. The first time I was just mentioning was that, if like Einstein said, an object travelling at the speed of light would expand to infinite mass was that unknowingly registering an object or light being plummeted into a black hole by its own gravity at light speed? The second was on the experiment of plants being grown in weightlessness at the ISS in an article on the National Geographic website. The article had failed to mention that plants in weightlessness or other levels of gravitational attraction didn't need gravity for structural form and only said that they did not need gravity for growth. I also added that plants are really clasping on to a substrate rather being forced down by gravity on our own planet, proved when successfully grown in weightlessness. I also mentioned rootless airplants as a fine example of how plants would structurally fare very well in outer space without the need for roots. Also, I wrote that even though plants had evolved their structural form influenced by Earth's gravity, the fact that they can grow well without it is an exaptation. (finishing this post soon. Work in progress)
