According to some sources, there is an article all about Eternity and how time has to end, and we go into eternity. Then it said that in Eternity, nothing ever changes, and the whole physical universe(earth) just dissolves. One source said that at the end of time, Earth and Heaven become one. Another source told me physical stuff all dissolves. Many churches teach that in Eternity, we never can know everything. I read that once the Restitution of all things occurs, there will be all sorts of new things to learn and all kinds of activities to do so we would never be bored. But according to some sources, they state that Eternity is exactly the same. Sounds a bit boring. But I dont really recall the bible teaching much on the subject of Eternity, or anything about it.
