If you are fascinated by the Book of Revelation I would encourage you to read Heaven by Randy Alcorn.  After reading that book I read through Revelation again and got a better perspective of heaven.  Now, I know it is only the author's take on things, but I feel he is right on with lots of what he wrote.

New heaven and a new earth - what a great picture that brings to mind.  Just read through these 5 verses and see if you don't come away feeling really good about things.  Verse five is my favorite, "I am making everything new!" Oh, I can't wait.
Revelation 21:1-5 (NIV)

 Then I saw a new heaven and a new earth, for the first heaven and the first earth had passed away, and there was no longer any sea.   I saw the Holy City, the new Jerusalem, coming down out of heaven from God, prepared as a bride beautifully dressed for her husband.  And I heard a loud voice from the throne saying, "Now the dwelling of God is with men, and he will live with them. They will be his people, and God himself will be with them and be their God.  He will wipe every tear from their eyes. There will be no more death or mourning or crying or pain, for the old order of things has passed away."  He who was seated on the throne said, "I am making everything new!" Then he said, "Write this down, for these words are trustworthy and true."
