Here's what I'm driving at: appeals to science, even in audio, while powerful, are not always conclusive, even in areas where the physics is thought to be thoroughly understood and determined. Take the belief that nothing can move faster than light. This tenet was held to be inviolable up until thirty years ago, but it was wrong. In the 1980s scientists discovered that there is something that can indeed move faster than light, and that thing is space. Hence inflation, the incredibly rapid exponential expansion of the universe after the big bang. Space itself expanded faster then the speed of light, and did so without violating relativity, which says that particles can't travel through space faster than light. No one dreamed that the expansion of space itself could outstrip light. During inflation, space grew at a faster rate than light can travel.
"At the end of the 19th c. a number of famous physicists claimed that we knew everything. There was supposedly nothing else to be learned. Everything else was just a detail -- engineering, in a sense. Then along came quantum mechanics and general relativity and special relativity and changed the world. We shouldn't think that we know it all." - Alex Filippenko
"There are many things that physicists and astronomers are doing now which twenty years ago would have been thought impossible." - A. F.
"Look at the history of physics. We've often thought we know how things work, and we were wrong." - A. F.
So when anybody says to me, "That's physically impossible," I always leave open the possibility that it might be possible after all.
