Well, think about it this way—
any sort of existence outside of our own perceived and known reality is what many call false or not real, simply based on our inability to perceive or comprehend it, or to "prove" it. It's funny, because there are many things we cannot prove, and many things that are not tangible, such as truth, love, rightness, and yet we choose to believe these things.
These are not things that you could comprehend with a mind that adheres to the known laws of the world;
so what do you do?
One must come to the conclusion that anything outside of our reality ultimately does not abide by the laws of our reality,
that is, if you wish to comprehend/ponder anything outside of our reality.
So now, in order to better understand or explore heaven/hell, which is ultimately outside of our perceived reality, you need to find a source of information that also exists outside of reality. Probably a reliable one, too.
Where would anyone find such a source?
Well, God happens to exist outside of our reality, and happens to be the perfect source of truth and love. Many would call Him false or non-existent, but remember—be willing to think outside of your own perceived reality, and you'll find Him.
James 1:5-6 — 5 If any of you lacks wisdom, let him ask God, who gives generously to all without reproach, and it will be given him. 6 But let him ask in faith, with no doubting, for the one who doubts is like a wave of the sea that is driven and tossed by the wind.
God is waiting for you—He loves you.
May God bless you in Jesus' mighty name. Amen.
