Can black holes erase information forever?
Imagine you accidentally delete a photo from your phone. You don't remember what it was, but you know it's gone forever.
In quantum mechanics, there's a puzzle about whether information is lost forever when something falls into a black hole. It's like the photo you deleted; it seems gone, but maybe it isn't.
Example
If you delete a photo, it's gone for good. But in quantum mechanics, there's a rule that says information can't disappear completely, even if it looks like it did when something falls into a black hole.
Remember this
Black holes challenge our understanding of information preservation in quantum mechanics.
