I believe that there's a switch in human brain, after thinking too much about some things (maybe, coincidentally, the universe is the greatest one of these things) ti goes off and you become crazy, or in denial.
A friend of mine calls this state (or the fear of this state) "The pins" because one time he had a panic-attack and felt like a trillion pins were colliding inside his brain.
He is a very intelligent fellow btw but he gives the complete middle-finger to technology, otherwise I would have him join this forum.
One day I was discussing with him this exact topic. And we concluded that either of these two things exist:
1. The universe has a purpose of absolute intelligence, hinted by the existence of evolution. Why? Maybe because someone (...) can later use this intelligence to fight another intelligence in his giga-cosmic fighting board game? who knows. The Consequence? The (this) universe is probably going to end when the realization comes.
2. The universe has the purpose of a "majestic story being told". Why? For the beauty of it. A great love story has a great beauty in it. Even something absolutely horrible like Operation Barbarossa despite the miserable onslaught of everyone involved, has some kind of awe and morbid beauty, you'll have to admit. The Consequence? Absolutely no-one can suggest absolutely nothing, a movie could end in miserable futility (Thelma and Louise), marginal hope (Terminator 2 - The Judgment day), heroic defeat (Braveheart), or even heroic victory (Scent of a Woman). That might suggest cyclic cosmology too.
