What do believers believe heaven or hell are like?

Hi Schrafinator,
Being raised as a Catholic I was taught variations on what H & H are.
Not being satisfied with any descriptions until one day I read some things that Saint Thomas Aquinas wrote. Although he lived in a time of Aristotilian thinking and superstition, I still sometimes read his writings. He described Heaven as a full union with God, and Hell as a separation from God. Vauge as usual these theologians but it left me with a idea of what it would be like to be in full union with something such as God.And how utterly complete one would feel to be one with God. Saint Thomas also said that the punishment for sin is the attachment to the sin. We sin, then it becomes easier to sin again. And what ever the sin is we are drawn deeper into the dark nature of what we are capable of and further away from grace and further away from God. (I make no sugestion that any of this is fact it is merely my own understanding of the concept of Heaven and Hell)
