Heaven exists as celebrating on Earth. Hell exists as suffering on Earth. Both mindsets, emotions and feelings rely on your current and past condition(s). As of now there is no objective way to experience Heaven and Hell in the afterlife, if it even exists. But, you can cooperatively experience them while on Earth in your physical and mental existence. What exists beyond the physical and mental constructs of the universe? Is there another way to consciously exist without a body or mind? What if you could break free from the restraint of time and become timeless?
Actually (timeless) you right about that part in a way because Albert Einstein did prove that there are 20 different dimensions and most likely more, right now we're in the 3-d dimension i think i'm not sure check on google cause its crazy when you read the entire thing. You said Heaven exists celebrating on earth? what do you mean by celebrating?? cause on earth most people take celebrating as party's but when Sodom and Gomorah did that they were destroyed by God proving that it couldn't have been Heaven and in the last chapter in the book of Proverbs states that the only one's who recieve beer or alcohol are the one's that are perishing, people are perishing in Heaven?? In Gen. chapter 1 it says God created the "Heavens" yes with an "S" indicating there is more then 1, the first one we see the physical when we look up in the sky. Apostle Paul testified that Christ made it to the 3rd Heaven which Jesus Christ described as paradise. Then how about the 2nd Heaven, one verse says "Kingdom of God is within you" Jesus Christ represents the Kingdom of God in the bible then how do you recieve Jesus Christ inside of you in order to have Heaven inside of you?? John6:53 Whoever eats Jesus Christ Flesh and drink his Blood they recieve eternal life and Jesus Christ remains in them and he in Jesus Christ..Doesnt mean to to Israel and start digging looking for his blood but Jesus spoke spiritually, Mathew26 shows that the only time Jesus Christ promised his flesh to eat and blood to drink is through the Passover bread and wine. To experience the 3rd Heaven or Hell on earth is actually impossible. Heaven is a spiritual world the invisible world, scientists prove there are over 200 galaxies, then what is in the center?? 3rd Heaven. Bible says we can't even imagine .10% of Heaven or Hell, if fire on this earth hurts alot and can burn us then how much worse it is for the spirit in lake of burning sulpher, so much worse, then how much more amazing Kingdom of Heaven if we have things that make us happy on earth say we can never be happier, according to the bible we can be more happy then that in Heaven because that happyness is not even 1% of how amazing Heaven is.
