I found ths quite intesresting and thought provoking quote by
Dr. Werner von Braun, well-known for his part in pioneering the U.S. space program. He 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."
Kalyani- Dr. Werner Braun's statement suffers from contradictions. No doubt Science has found that nothing can disappear without a trace. Science knows only physical body that does not just vanish but is burnt or buried. Thus this is transformed int soil or gas. The concept of transformation cannot be applied to soul, which has no physical existence like mass, weight or other attributes.
