Scientists once laughed at people who believed in invisible waves. Then the theory of electromagnetism demonstrated that we are immersed in an ocean of invisible waves. Scientist sneered at people who believed in invisible energies. Now scientists say that 95% of the universe is made of dark energy and dark matter that are wholly invisible. It won't be long until scientists have accepted the reality of ghosts. Imagine a soul phone for contacting the dead, such as Thomas Edison believed possible. Would it be the most popular invention ever? Whom would you call? – famous figures from history, saints and prophets, or your dear departed ones? Or would you try to get through to God himself, and hope you didn't get a crackly connection? Atheists always get “No Signal.”
