Hi, it's quite long time I didn't post so let me start by saying that I'm not religious, not even a deist. Let me also say that I'm just a layman intersted in science without any real knowledge of theoretical physics. I'm putting this question from a purely scientific standpoint, without any metaphysical intentions. Conservation of information is some kind of dogma in modern physics, it is frequently mentioned that the possibility of its violation in black holes fueled the big debate between Hawking and Leonard Suskind, finally settled in favour of Suskind and the confirmation of conservation of information. How does physics handle this principle when it comes to biological organisms? I guess there is no denying that our brains gather and store information. Before we die we have memories of our lives, we have learnt things, we can even have memories of dreams we have had during our life. When we die the atoms which formed our body get scrambled to a point where we have no hope of retrieving information from them, but if we understand information as purely positions and momentums of subatomic particles, we can say that the information of our bodies is still there, contained in all the constituent subatomic particles, even if we can not practically recover it. But, can we say the same about the information which was in our brains before we died? Do we really believe that the information of a dream of a person who lived 500 years ago is still contained in the subatomic particles which formed his/her brain at the time? Does information generated or stored by biological organisms, and the fact that these organisms die, challenge the principle of conservation of information?
