Murray Silver, of Savannah, Ga., was one of the speakers at the Ybor City Paranormal Conference on Saturday. His one-hour speech rose and fell like a preacher's sermon, his voice booming across the theater without a microphone. "I have set out to prove the existence of ghosts through the scientific method," he announced. "I've gotten to the end of my investigation, and I'm here to tell you what I've found." He matter-of-factly described heaven, comparing it to a pyramid scheme, where only a few make it to the top. Then he described hell as not a place of suffering, but of purification. He described ghosts as people who don't want to move to the afterlife. [ Visit Website ]
