So, as the title says, I'm curious to know what (theoretically) happens to human consciousness after we pass away. Obviously no one knows for sure, I'm just curious to learn more about this particular topic, from a scientific perspective. I'll admit, I'm curious about this because in July of this past summer, a good friend of mine committed suicide, and today is/was her birthday; and I can't stop thinking about her I'm not religious in any way, shape or form, so I kind of just assume that she "entered the void" or "left the universe" in some way. Any information/links to theories pertaining to this is greatly appreciated. Thanks!
