AI Thread Summary
The discussion centers on the nature of information in relation to black holes and spacetime singularities. It asserts that spacetime singularities do not affect the irreversible formation of black holes. A key point raised is whether information can be destroyed, with a viewpoint suggesting that if information transforms into energy, it ceases to exist. The conversation emphasizes the need for coherent superpositions of "Everett worlds" to confirm the unitary dynamics of black holes. Overall, the dialogue explores the complex relationship between information, energy, and black hole physics.

The existence of spacetime singularities is irrelevant for the irreversible appearance of black holes. However, confirmation of the latter's unitary dynamics would require the preparation of a coherent superposition of a tremendous number of appropriate ``Everett worlds''.

The main question is can information be destroyed?
My answer is yes,no form of energy lasts forever,if information transforms into another form of energy,than it's all over-information is destroyed and that same information doesn't exist anymore.
 
Publication: Redox-driven mineral and organic associations in Jezero Crater, Mars Article: NASA Says Mars Rover Discovered Potential Biosignature Last Year Press conference The ~100 authors don't find a good way this could have formed without life, but also can't rule it out. Now that they have shared their findings with the larger community someone else might find an explanation - or maybe it was actually made by life.
TL;DR Summary: In 3 years, the Square Kilometre Array (SKA) telescope (or rather, a system of telescopes) should be put into operation. In case of failure to detect alien signals, it will further expand the radius of the so-called silence (or rather, radio silence) of the Universe. Is there any sense in this or is blissful ignorance better? In 3 years, the Square Kilometre Array (SKA) telescope (or rather, a system of telescopes) should be put into operation.
