Events That Would Shake Your Belief System Everyone has beliefs about the world, religion, etc. Most of us hang onto them closely, but in every belief system there are implicit assumptions that certain events will not happen in the future, and if these events were to actually occur, that belief system would have to be re-evaluated. For instance, I consider myself a Christian. Events that could shake my belief system include: 1. The discovery of another sentient species. 2. The creation of a self-aware, truely artificially intelligent machine. 3. The discovery of a method to create life at the cellular level. 4. The discovery of a method to make humans immortal. Any of those would force me to re-evaluate my belief system. What events would shake your "faith"?
