start to speculate if it will end and why it must end? When understood, the end of time becomes an inevitable certainty, not a matter of conjectures. Every incarnation of this world is a manifestation of its particular quantum state and it has a very, very precise duration. Not a second can be added or taken away. When the time is due, the Sun must rise on the horizon - it's as regular as clock. And when the time arrives for this cyclic rising and setting of Sun to cease, then the whole thing must be reversed because every action has a reaction. It's also as regular as the clock. All periodic dissolutions of physical world are regular. It's only a matter of time when the world must be dissolved in its present state. And that time is winter solstice 2012.
