Take a snow globe. Imagine we live in there. Know that form or mass is only 4% of what is there and what we can perceive with a normal state of mind. Know that there are people who perceived 'heaven' throughout history and that the experience was similar, only the conclusions from the experience were different (Budhism, Christianity, Islam, etc.) Heaven is all around and in you. I know it all comes down to belief which comes from faith which comes from hope if you heaven't experienced One of the more modern writers who came close to describing it is Eckhart Tolle. I would recommend "New Earth".
