COSMOLOGY is the discipline that deals with the nature of the Universe as a whole... whereas COSMOGRAPHY is the science that deals with universe describing both heaven & earth..

The universe is everything by definition. This means there is nothing outside of the universe. There is no noted end to the universe or line that someone could say this is where the universe ends and the outside begins.
NO because outside of the universe has no landmass
Heaven
There is no heaven, therefore the universe is bigger.
Here is how I define 'heaven': NOUN 1) (usually in the plural) the expanse of space that appears to arch like a dome above the earth 2) (usually with -H-) the supernatural domain outside the observable universe that serves as the abode of God, the holy angels, and the saints 3) any place or state of supreme happiness that resembles the supernatural heaven
No, there is not there is no edge to the universe, and there is nothing outside of the universe. there just IS the universe.
The name Universe refers to all that there is in existence, therefore nothing can be outside it.
If there is indeed anything "outside of the Universe", science has no knowledge about it.
