As an American, one of the most positive things that could happen to the world is the abolishment of the United States as a government. We’re directly or indirectly responsible for most of the ethnic cleansing that has gone on the last several decades.
Simple. True empathy for everyone. Literally feeling what others feel
So every time someone stubs their toe, every other human would feel the pain? Everyone would be completely overwhelmed by all kinds of feelings all the time.
I wish for one electron to disappear from every atom. The net result would be that all atoms would now have a positive charge.
True, it would not only end all life on earth, but also destroy the entire earth. But everything would be positive.
Unfortunately, this is not the case. There are plenty of atoms/molecules that have greater negative ionization states than -1. This wouldn’t even make everything neutral.
Captain Pedant… AWAAAAYYYY.
OTOH, if you shifted the ionization state of every single atom, then pretty much every molecule would end up flying apart. You can’t form H2O if hydrogen has no electrons at all; hydrogen becomes a single proton.
