Dr. Werner von Braun, well-known for his part in pioneering the U.S. space program, said that he had "essentially scientific" reasons for believing in life after death. He explained: "Science has found that nothing can disappear without a trace. Nature does not know extinction. All it knows is transformation. If God applies the fundamental principle to the most minute and insignificant parts of the universe, doesn't it make sense to assume that He applies it to the masterpiece of His creation -- the human soul? I think it does."
