Reply to comment by Awkward_Mongoose7679 in Seemingly Impossible: Nanostructure Compresses Light 10,000 Times Thinner Than a Human Hair by Shelfrock77

What? If that’s true then a human hair is 5 cells wide, which its not.

It was an over simplification but you can approximate a human hair to be about 100um and cells to be about 10um. Hence 1/10th. Depends on the hair and the cell type you looking at but it was just meant to illustrate the scale of what the article is talking about. i.e. very small

I retract my comment. I had no idea that a hair was so small / cells were so large.
