re: Life for Christians in Iraq worse now than under Sadaam

Basically, it involves the detectable ability of subatomic particles to spontaneously pop into and out of existence in a vacuum. The idea that matter cannot be created or destroyed is not technically true, though it is effectively true on the scales relevant to us. The (overly simplified) idea is that the creation of the universe was the sum of these quantum fluctuations. We can observe and measure spontaneous energy generation from spontaneous atomic generation in vacuums in laboratories. The energy emerges effectively from no prior starting point or precursor.

Here's a lecture from the author on the topic if you are interested:
