What is the hottest pepper and why is it so hot?
Bhut jolokia chili pepper is the hottest pepper. In 2007, Guinness World Records certified it as the world's hottest chili pepper. It grows in the Indian states of Assam, Nagaland and Manipur. See http://en.wikipedia.org/wiki/Bhut_Jolokia_chili_pepper.
Hot peppers are "hot" because they contain a chemical known as capsaicin. The more capsaicin the pepper contains, the more irritating the pepper, which we perceive as heat. The heat of peppers is measured as Scoville units.

Yeah, the Ghost Pepper, how sweet is that name. If you eat this you'll become a ghost.
