Episode 205: Fusion

November 1st, 2010

Episode 237 of 460 episodes

When the Universe formed after the Big Bang, all we had was hydrogen. But through the process of fusion, these hydrogen atoms were crushed into heavier and heavier elements. Fusion gives us warmth and light from the Sun, destruction with fusion bombs, and might be a source of inexpensive energy. We'll also look into the controversy of cold fusion.
