Where has all the information gone

In summary, H. D. Zeh discusses the concept of spacetime singularities and their irrelevance to the appearance of black holes. However, he also raises the question of whether information can be destroyed, stating that if it transforms into another form of energy, it no longer exists in its original form. This is a topic that requires further exploration and understanding.

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.
 

1. Where does information go when it is deleted?

When information is deleted, it is typically removed from the visible storage space on a device. However, the data is not completely gone and can still be recovered through specialized software or techniques. The specific location of the deleted information depends on the type of device and the method of deletion.

2. Can information be permanently deleted?

Yes, information can be permanently deleted through a process called data wiping or data erasure. This involves overwriting the existing data with random characters multiple times, making it virtually impossible to recover the original information.

3. Where is information stored on a computer?

Information is stored on a computer in the form of binary code, which is a series of 0s and 1s. This data is stored on a hard drive, solid-state drive, or other storage media, and can be accessed and read by the computer's processing unit.

4. Can information be lost forever?

Yes, information can be lost forever if it is not backed up or stored in multiple locations. Hardware failures, software errors, and human error can all result in the permanent loss of information.

5. How can information be protected from being lost?

To protect information from being lost, it is important to regularly back up data on external storage devices or in the cloud. Additionally, using reliable hardware and software, implementing strong security measures, and maintaining good data management practices can help prevent information loss.
