Alright so um, I'm not a Christian. But I found this questions actually beautiful(since you spoke really openly. believe me not many people are able to ask questions like this) and wanted to answer some of them according to my belief, Islam. (and if you are not interested feel free to pass xo) Since the main reason I'm a muslim is our afterlife belief.
Let's start with 'what is heaven, actually'
It's an empty place. Like, an actual empty place that has no mass or volume. Both heaven and hell is. We, the people will be the ones filling it.
I know it sounds a little unreal but bear with me, I'm going to try to explain it with my broken english.
Our actions will be the ones filling the place. As an example, our common belief is everytime you remember and say God's name there will be a brick from pure gold on your house in there. Of course it's a metephor for the endless wealth you can get in Heaven. I personally wouldn't like my house pure gold. But imagine what can you get as an alternative of a brick from pure gold. And by brick by brick, you'll be the one who built your own eternal space.
I personally find this more beautiful than the common 'perfect garden' belief. People come in so many different shapes. We all have different desires, goals, likes in life and we will have them in afterlife as well. So the thought of I will be the one who create my own space is wonderful for me tbh.
"Is it unchanging?" No, it changes with every little want you have. You got bored from cyberpunk aesthetic and want a dark academia place like Hogwarts? You will probably get it. Though of course, if your actions in actual world is not enough for that, you will probably get an alternative of it. There's so many different kind of beliefs about it. And as a rather ignorant Muslim who haven't read so many things yet, my personal thought is you'll get what you deserve, and you will be satisfied with it.
"What about angels?" I personally haven't seen so many things about the angels place in Heaven. I just know that they will be there to serve us, sorry :(
"Will we get to see the big holy G??" Well, first of all our God's name is Allah. And no, not everyone will get to see Allah(I refuse using masculine pronouns to refer to a God since we believe it has no common thing with us humans, including gender. Bear with me)
We have holy figures as well. They are Allah, prophets(from Adam to Muhammad(sas)), and some of the angels. Not everyone will get to see them, you have to earn it. Some will have the opportunity to just get a glimpse, some will even get to talk etc. I don't know so many things about this topic either. Just wanted to say not everyone will be get to.
"How in the world so many people will be able to live in a same place?" So um, I know it will be hard to explain but Heaven won't be a place like a country or even a planet. It won't have boundaries, it wont have a government, hell it won't even have rules according to some. So population wont be a problem.
"What will we do, just chill?" I mean if you want?? There's no such a thing as 'we will do this in Heaven' either. Just, whatever you desire(if you have earned it).
"Could you get kicked out?" There will be no such a thing as 'wrong thing to do' in afterlife. Like, just no. I don't know if we wont be able to think about bad things or the bad things wont get consider as 'bad' things anymore. But well, I heard that Heaven will be a place that has no pain or death in it.
"Could you even interact with anything on earth?" I dont have the exact answer to that but just wanted to say that our common belief is the things we like on earth is just a mere shadow of the ones on Heaven.
"Can you be aware of anything going on Earth?" The simple answer is No. More complicated one is there wont be anyone in Heaven or Hell till the last Human on Earth die. So there won't be anything going on Earth.
Amyway uh, as I said I'm an ignorant person in most topics so my answers maybe wrong or unnecessarily detailed. I just want to add that, we don't have so many strict answers to our questions about afterlife. We just have our own thoughts and believes along with sentences from Holly Books or quotes from prophets. Don't let them fool you thinking there are only two options, Garden of Endless Wealth and Joy and Fire™. Life in here is already complicated, we can't think afterlife won't be.
The concept of heaven makes me have so many questions:
First of all, what is it actually? I've heard many speak of a garden, Christians often say "the kingdom of God", which makes it sound like a human state.
Is it unchanging? Or is it bound to the progression of mankind and our changing views of what a good forever would look like? Does God remodel it with us in mind? Or do we have to take whatever he builds for us?
Angels man, are they like robots or npcs? Or are they like government employees?
God himself, does he do anything particular? Could you just go into his throne room and have a chat with him? Have dinner with him? Play chess with him? Or is he some absent ruler you hear about but never see?
What would the big G even look like? Alot of art represents him like a bearded old man. I've heard on several times that he says he's pure love, so could he manifest as the person you loved the most in life? Does he just have an incomprehensible form? Like a blinding ball of light with a disembodied voice?
Also, the mortal souls themselves, alot of humans have died already, so assuming if atleast half of us go to heaven, that would make for several billion citizens of heaven.
Human nature means there would be thousands of spoken languages and several versions of each language (due to time) spoken in heaven simultaneously.
What do the souls do once here? Do they chill, do what they find pleasurable for eternity? Like, could you find Beethoven chilling while composing his 100th symphony?
Also on souls, would people with disabilities be "cured" of them, since this is a place with no pain or discomfort right? Would you have no more depression or other mental illnesses? If you lost a limb in life would you get it back?
Could you get kicked out? Or is your stay only determined by your actions in mortal life?
Since morality has also changed a lot would there be friction between new souls and old souls?
Can you even interact with anything made on earth? Like, can you have ice cream or read a shakesperian play?
Could you be aware of anything going on on Earth? Or once you arrive, are you cut off forever?
So many questions man, Christians feel free to comment, if you don't feel like this is heresy of course.
