The human mind is a multidirectional, metaphor-building life-interpreter that travels directly form life to life. Life is an unidirectional time machine that travels directly to the future. The future is an imaginary extension of the present. The present is an imaginary extension of the past. The past is the source form which everything, as we know it, comes. It is real, because it is certain (when a lot of people agree to remember the same thing).
I took a trip to the future once, but it wasn't half as good as they put it on movies. It was imaginary, but it well could have been real, no one would believe me either way. I'll try to describe what I saw in the future, although I must say that it wasn't promising nor vivid, as I could only see the ideas that will be wandering among human minds.
Powerful people will struggle for power, curious people will struggle for answers, wealthy people will struggle for money, and needy people will struggle for life. The rest—those whose power is not enough to be called powerful, whose curiosity is not enough to be called curious, whose money is not enough to be called wealthy, and whose hunger is not enough to be called needy—will go on with their lives without any considerable struggle, taking the free ticket life has given them for a certain trip to the future.
A trip to the future is pretty much like a trip to the past: it's all about placing your mind in a nonexistent place, far, far way from where your body is (to a place where it once was, to a place where it will probably be).
I think that space-time is a closed loop surrounded by a spiral-shaped history. So, if you were to take a real, infinite trip to the past (or to the future), you would pass by the imaginary spot we call present an infinite number of times. The same happens with an imaginary, infinite trip to the future (or to the past): if you spend your life trying to figure out what will happen in the future and/or remembering how great or awful the past was, you will pass by the imaginary spot we call present an infinite number of times.
