I got to thinking about this one night. I don't personally believe in an afterlife but if there is one, how does it work?
Does everyone see everyone else? If so, how would you find all your friends and family you want to be united with?
What if there's someone there you don't like?
Are your pets there, too, or are they in a separate section of heaven and you can go visit them?
On Earth, people have to eat to stay alive but once your in Heaven you wouldn't have that need. Would people still eat because it's something from their mortal life they enjoy or would they not eat? Is there something different that people live on in the afterworld?
Do people wear clothes in Heaven?
Does everyone eventually get to Heaven? If you pay your penance in Hell can you then move on to Heaven?
What age is a person in Heaven? Do they remain the age they were when they died or do they get to pick an age to spend eternity in? What about people who die as babies? Do they stay that age?
What about babies that die in the womb? Do they go to Heaven or do they not count?
Does everyone speak the same language in Heaven or can they understand each other regardless of the language they speak?
Can someone get tossed out of Heaven if they do something to disgrace themselves there (like get in a fight)?
Is there music, art, sports or movies in Heaven? Are you allowed to drink alcohol there?
Are people from Earth the only inhabitants of Heaven or if there's life on other planets would they be there too or would they have their own separate Heaven?
Are there seasons in Heaven? Night and day? Do people sleep in Heaven or do they stay awake all the time?
Can you meet anyone in Heaven, like if there's a celebrity or a way distant relative of yours you'd like to meet, or are you limited to people you knew in life or just relatives?
Do people have jobs or tasks in Heaven or do they just mill around shooting the breeze through eternity?
Does Heaven have different climates or landscapes, like mountains, oceans, fields, cities or is it all the same?
Are there gods, angels, or other immortal beings in Heaven? Can humans become angels? Is that our purpose for going to Heaven?
