Hey @justtryme90 I am very sorry about this issue. It took me some minutes to figure out what has happened, because I always try to write original content.

I usually collect material in a draft file, where I just simply copy links or text into it, after which I start to write my own version in a different file. It seems like I have accidentally mixed up something between this two versions.

I assume this is the source you were talking about, right?: http://www.plenglish.com/index.php?o=rn&id=20969&SEO=light-always-travels-the-same-distance

That text it a 100% copy, because it is contained as is in my draft file. I haven't saved the source of it but this is the only suitable explanation for me.

I am sorry for the inconvenience and I have replaced the double plagiarized version :-) .
