Location of heaven and Hell

Every curious mind wonders about heaven and Hell. People state that it is scientifically unrealistic for heaven and hell to be present.

My opinion:

They surely are located somewhere, but where is not exactly known but even I could make a couple of scientific guesses beside all the other not so scientific ones:

1-) May be it's out side this universe, it's outside the expanding boundaries of time and space. Science agrees that the universe is expanding since the Big Bang ! But where is it expanding to ?
May be outside this universe is a state without space or time (because these are present in the universe only). In this state we come into an ecstatic communion with everything and we experience eternal bliss and serenity and that is Heaven.

2-) May be a billion light years away from here there is a huge glowing Giant star a million times larger than the sun. It's surrounded by rims of millions of planets each within the living zone of this massive star. Each of these planets is unique and beautiful with wide fields of grass and flowing rivers of milk and honey and with trees the size of mountains and the mountains even larger. The sand is of musk, bring joy and no tiredness to the feet which walk on it, the breeze is cool bring a refreshing aroma with it. Then there are green hills the size of continents on which you could lay forever, watching the pink clouds bring drift across a blue lake pouring a sweet rain to make the water even happier than before.

Then there are other planets and asteroid belts present near the star some being fiery hot and full of deep trenches and thorny trees.

3-) May be it's right around us, in another dimension or maybe several other dimensions. Science and mathematics agrees that there are at least 12 dimensions!

The point is they could be anywhere because God created them and He can do what he pleases.
It's up to us to either make it to Heaven or Hell.
