“If, years later, I do use the slit detector to observe which way the electron went, it will mean that many years earlier the electron must have passed through one slit or the other. But if I don’t use the “slit detector,” then the electron must have passed through both slits. This is, of course, extremely weird. My actions at the beginning of the twenty-first century can change what happened thousands of years ago when the electron began its journey. It seems that just as there are multiple futures, there are also multiple pasts, and my acts of observation in the present can decide what happened in the past. As much as it challenges any hope of ever really knowing the future, quantum physics asks whether I can ever really know the past. It seems that the past is also in a superposition of possibilities that crystallize only once they are observed.”

“Small shifts in your thinking, and small changes in your energy, can lead to massive alterations of your end result.”

“In fact, the mere act of opening the box will determine the state of thecat, although in this case there were three determinate states the catcould be in: these being Alive, Dead, and Bloody Furious.”

“Holes in the fabric of the universe exist, but they will change over time. Let’s hope that we find one before it does.”

“‎In modern physics, there is no such thing as “nothing.” Even in a perfect vacuum, pairs of virtual particles are constantly being created and destroyed. The existence of these particles is no mathematical fiction. Though they cannot be directly observed, the effects they create are quite real. The assumption that they exist leads to predictions that have been confirmed by experiment to a high degree of accuracy.”

“Theology, philosophy, metaphysics, and quantum physics are merely ways for God to have his smart people believe in him”

“The cosmos is within us. We are made of star-stuff. We are a way for the universe to know itself.”
