I was curious if, when someone dies, are the informetion, such as memories, stored in the brain lost? Is it possible to extract that information without somehow bringing life back into the person?
This is more a question of philosophy than physics.Thanks for the replies, that would be a pretty convenient technology if we could probe the memories of the dead, definetly be a help to crime investigations.
The reason I asked the question was to know if death really contradicts that information cannot be destroyed, if it does, then wouldn't the information have to leave the body somehow or another, perhaps in the form of a soul?
No. "Information being destroyed" has a somewhat different meaning in cosmological circles.Sorry about that, but anyway is information "destroyed" when someone or something dies?
Yes, the information is lost. Even for alive people the memory changes and something gets forgotten, something gets distorted. And dieing destroys the information. That is why they kill for "knowing " too much.Sorry about that, but anyway is information "destroyed" when someone or something dies?
Don't forget to mention that the universe is not actually Newtonian, that it's not possible to measure position and velocity to an arbitrary level of precision due to the Heisenberg uncertainty principle (because they don't exist in precise states but rather a superposition of probable states), and that the prevailing theory of QM assumes an element of randomness in everything that does cause information loss!In a Newtonian universe, every particle and ray in the universe can have its position and velocity - in principle - measured to an arbitary level of accuracy. You could - again, in principle - take the sum total data of every particle's position and movement in the entire universe at any moment in time, and reverse the process, and trace it all the way back to the Big Bang.
