So you've had a close encounter with a UFO. Or a serious interest in the subject of extramundane life. Or a passion for following clues that seem to point toward the existence of a greater reality. Mention any of these things to most working scientists and be prepared for anything from patronizing skepticism to merciless ridicule. After all, science is supposed to be a purely hardnosed enterprise with little patience for "expanded" notions of reality. Right?
