1)A few years ago NPR had a guest speaker who spoke on Black Holes,according to the guest speaker black holes (if we were able to make them) could be made by making particles infinitely small and applying gravity,or something along the lines of those words. Bear in mind I am a high school grad w/no collage,so please keep your responses very simple and even a yes or no would be ok. There are follow up questions that I would like to ask after this but I'm not sure you have a place for questions relating to my experience yet.
To answer this question for you.
Stars come in many sizes and shapes, but they usually radiate light. Depending on their nature, they radiate some sort of light. White, yellow or red. But they all radiate immense heat. A Black Hole, is a star that radiates only heat, and no light. Pretty much like coal, the white coal is the hottest, not the red or yellow one.
Concerning the star size, and wether it collapses on itself. Whatever it's gravity may or may not be, is not really important. As they are only speculations.

Totally wrong. In every statement.
