Because he is the only one who died and came back to life on the third day, Jesus knows more about death than everyone who has speculated about what happens after we die. Even near-death experiences do not tell the whole story.

Hell: Hades and Gehenna
Jesus used two different words for hell. The first is Hades which is a temporary place where the dead go until the final judgment. Sometimes Hades is translated as grave. "The sea gave up the dead that were in it, and death and Hades gave up the dead that were in them, and each person was judged according to what he had done." (Revelation 22:13)The second word is Gehenna which literally referred to the Valley of Hinnom, which was Jerusalem's dump where the garbage was burned. Figuratively, Gehenna refers to the lake of fire. "Then death and Hades were thrown into the lake of fire. The lake of fire is the second death. If anyone's name was not found written in the book of life, he was thrown into the lake of fire." (Revelation 22:15-16)
Paradise, the Millennium and the New Jerusalem
At the end of the Millennium comes the final judgment described above. "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." (Revelation 21:1-4)
