Does life present any information paradox?

Click For Summary
SUMMARY

The discussion centers on the information paradox related to black holes and its comparison to the loss of information in human brains upon death. It establishes that while black holes may violate the conservation of information as per certain models, the death of a human does not contravene known physical laws. The conversation highlights the distinction between the types of information lost and emphasizes that entropy behaves differently in these scenarios. Key references include Landauer's principle and Charles Seife's book, "Decoding the Universe," which explore the relationship between information and entropy.

PREREQUISITES
  • Understanding of black hole physics and the information paradox
  • Familiarity with entropy and the Second Law of Thermodynamics
  • Knowledge of Landauer's principle regarding information storage
  • Basic concepts of quantum states and their relation to information
NEXT STEPS
  • Research the implications of Landauer's principle on information theory
  • Study the information paradox in black holes and its resolutions
  • Explore Charles Seife's "Decoding the Universe" for insights on information and entropy
  • Investigate the relationship between entropy and information loss in biological systems
USEFUL FOR

Physicists, information theorists, and anyone interested in the intersection of information, entropy, and the implications of black hole physics.

This question might rather be posted in Biology but since the information paradox is usually the subject of black hole physics I thought physicists may be better placed to answer it.

The fact that information may be lost in black holes is considered a paradox, information is believed to be conserved by a conservation law.

Now living beings (let's take a human brain as the extreme example) accumulate a great deal of information during their lifetime, that's what brains do, process and generate information. When the brain dies all that information is presumably lost.
Does this present a paradox in a similar sense as the black holes case? I know the information paradox in black holes refers to the information regarding quantum states while the information generated by a brain is probably of a different nature.

I think you're mixing up two different meanings of the word "lost." In some black hole models entropy has been predicted to decrease as matter is captured, which would constitute a paradox considering the reliability of the Second Law. When a human being dies, total entropy isn't predicted to decrease. In both cases information is lost, but the second definitely does not violate known physical laws.
 
information is information...there are many storage mechanisms...entropy is a special case of information...measurement is the act of extracting information from a particle or other entity...nature attempts to increase entropy and disripate information...

you can get some related insights from Landauer's principle regarding computer information storage and entropy increase...
Another source of insights is Charles Seife in DECODING THE UNIVERSE where he takes a look at the universe and life from an information and entropy perspective...altogether fascinating an a bit baffling...
