In fact I've just about decided that there is no present or future in the material world. All that we do is past as we do it. The future exists in our mind and when it enters the 'present' it is no longer either of them. The past is a fragment of our memories. We forget most of what we experience and the older we get the more we forget.
Time makes no sense.
It is designed merely to ensure that we 'do' something with life within the space of time. Jim from Alabama is sure it is all in the mind. Since weekends fly and weekdays drag on, but years continue to go faster, then time travel must be a mental phenomenon. Just as it's safer and easier to send probes to the outer limits of the solar system, we will be able to send probes to the future and to the past. Another Jim sums it up - at the speed of light.
