The Black Code (more formally, Military Intelligence Code No. 11) was a secret code used by US military attachés in the early period of World War II. The nickname derived from the color of the superencipherment tables/codebook binding. The code was compromised by Axis intelligence, the information leak costing a great many British lives. (Wikipedia).
Are Black Holes Really Black...or Invisible? Real Black Holes on Earth!
In this video I show you what a real black hole would look like near earth! Is it really black, or is it invisible? This videos stems from a previous video I did with Black 2.0 paint (the blackest black) with the world's brightest flashlight (32,000 lumen). I mentioned that the black 2.0 l

Making Black Holes is HARDER than you think!
Black holes aren't just a product of general relativity, but also require quantum mechanics. In this video, we'll take a look at how the Pauli exclusion principle and Heisenberg uncertainty principle apply to black holes. Making a black hole is actually quite difficult. ___________________
