Scientists work out methods for finding the difference between the magnetic moments of protons and antiprotons and see that they’re the same.
Why are we here, anyway? No, not in the what’s-the-meaning-of-it-all sense, but why haven’t matter and antimatter completely obliterated each other, the universe and us? In nature, two identical things that are 180° out of phase with each other — as matter and antimatter seem to be — cancel each other out. So, um, why are we here?
If you cloned yourself perfectly, would the clone have the same mind? At the heart of this question is an investigation into what – and where – consciousness is.
Consciousness is one of the big questions humanity longs to have answered. What makes us human? What is the experience of consciousness that we all feel exists intuitively, but that we have no evidence-based theory to explain — and also where is it? There are many schools of thought on the topic. Philosopher Alva Noë says consciousness isn’t in the brain, and that looking for it there is like "trying to find the dancing in the musculature of the dancer or trying to find the value of money in the chemical composition of the dollar bill." Then there are philosophers and neuroscientists who believe that consciousness is caused by neuronal oscillations, and that it’s contained in the brain. For some, it originates there but it could also be an emergent energy or vibration that goes beyond our bodies. There is no proof either way, and until there is, Bill Nye personally takes the molecular view. Do you agree that our physical, chemical brains are the beginning and end of consciousness?
