From a physical perspective, information is a representation of some kind of state or pattern in a physical system. According to the laws of thermodynamics, information cannot be destroyed or deleted, only transformed or transferred from one form to another.

This is because information is a form of energy, and according to the first law of thermodynamics, energy can neither be created nor destroyed, only converted from one form to another. Therefore, any information that is deleted or erased must go somewhere else, either in the form of heat, light, or some other kind of energy.

Furthermore, the second law of thermodynamics states that the overall entropy or disorder of a closed system tends to increase over time. This means that any attempt to delete or erase information will inevitably lead to an increase in entropy, as the system becomes more disordered and chaotic.

In summary, physical laws dictate that information cannot be completely erased or deleted, as it can only be transformed or transferred to another form of energy.
