Collisions. Ideas mate with other ideas to produce idea children. Read other ideas. Compare your new ideas with your old ideas. After the Big Bang, the rest of the universe was basically created from collisions. Hydrogen atoms collided to form helium atoms, and on and on until all of the elements were created. Dead stars collided with asteroids to create planets and water and ultimately life. Collisions are the fundamental life-giving processes of the universe. Ideas are no different. The best ideas come from collisions between newer and older ideas.
