And that's how thing[s] will end and remain ended.
That's not true, actually. You see, beyond the accelerating universe, by the time of the end of which you speak, we will have built ... "God", for lack of a better word. By that time, we have looked at each particle and each vibration of each string and determined where it came from and where it is going (yes, there's no random), allowing us to calculate everything back to before the big bang.
Everything will be known - every path of every falling leaf anywhere in the universe, ever. Every action, every thought and every feeling of every creature that ever lived will be known, in effect raising everyone from the dead in a big collective consciousness beyond this universe and all the matter and energy in it. Thankfully there must have been a universe about around here before, because out there on the outside, was matter we could build our collective of. We need all the matter in this universe. We need to start it again, in the exact same way it once started. Everything in this universe will all happen exactly as it happened and is happening and will happen once more.
Why we need to do that? I'll get into that later, unless I've all ready mentioned it before. But now I have to go. These are very hectic days for this weary "time-traveler". My adventures on this earth at this point in history are not that important. They are dwarfed by the cosmic storyline, but they might be an amusing read if I get time to write about them.
Do good. You will reap the benefits later.
Sincerelly,
Future Person
