So, you are saying I don’t have to know where god is topray to him and i also do not have to know quantum theory to be Catholic. Good. That is a start, anyway.

I was interested in the answers to this as well. I didn’t know specifically what the church teaches on this - I was ready to believe anything it tells me about heaven, because it’s proven itself to me over and over on every other question which has come up.
There are some things of which I finally know that my human mind will never conceive. God, Himself, is unknowable in all of His attributes. I can never comprehend it.
I can catch tiny glimpses of various aspects of God - His mercy, for instance - I see that it is like an ocean compared to the tiny droplet which contained all my sins. Even then, I cannot comprehend an ocean large enough, so the analogy falls short. The point is that my sins are not large enough that they cannot be forgiven and that I was painfully arrogant to ever believe that they were. I can see a tiny glimpse of His perfection when I consider the human body - how a new life can come from two individual cells from two human beings. I can see a tiny glimpse of His artistry when I watch the evening clouds blaze in unpaintable colors in the sky. I can’t imagine God in his fullness.
I guess I’m kind of like “But for Grace,” in that it really doesn’t matter to me much where heaven is. I have had tiny glimpses of heaven in prayer and meditation, so I know that it exists - that’s enough for me.
I just heard Father Groeschel the other day - he told a lady that she could picture God as something outside her or inside her when she prayed to Him. When I pray to God, I pray to “our Father” - a genderless Creator of all that is - something that is both inside and outside of me at the same time. When I pray to Jesus, I sometimes picture myself with Him in the Garden during the Agony or at the foot of His cross or watching Him ascend into the skies after His resurrection.
Keep searching.

If you are even a tiny bit willing to find and to know, the truth will fall into your lap.
I wish you even greater joys than I have found in Christ!
