The world may not end per se, only the world as we know it:

"I suggest that we have entirely misunderstood the character of time. We are not being pushed by the force of causal necessity; we human beings, like the rest of nature, are reacting to the siren song of the transcendental object at the end of time. We are on a collision course with an event for which there is barely language. We are on a collision course with a temporal vortex of some sort."

Tool's next album is, perhaps, the Trancendental Object at the End of Time. Terrence McKenna predicted it.
