Time, as we know it, is only an illusion. We usually think of time as having three parts - Past, Present, Future. But what is the Past - only a collection of memories. We can't experience the Past, we can only remember it. And we can only remember it in the Present (furthermore, our memories are noticeably unreliable). There is no objective thing that we call the Past; it can't be measured in any way; our only contact with it is in the Present.
And what is the Future - only a mental construct in the Present. We can't experience the Future until it "becomes" the Present. Until then it only a hope and dream. We can project what the Future may be like, but we are considerably less accurate than when we remember the Past. There is no objective thing that we call the Future; it can't be measured in any way; our only contact with it is in the Present.
