This article is posted on twitter with the byline: "You, me, and even aliens from Alpha Centauri could arrive at the same Planck units." but does not explain why. http://www.symmetrymagazine.org/article/the-planck-scale I believe I have read (but cannot find the reference now) the following explanation: The energy of an electromagnetic wave is inversely proportional to its wave length. The Planck Length is so small that calculations show something vibrating within that length, would be so energetic it would become a black hole. Does anyone know if this is true or false?
