I'm not a physicist. If I weren't so lazy and I had unlimited time perhaps I would become one so I could answer a question that's been bothering me for a while. Only today this question occurred to me in a different form than it had previously.

Does the future exist?

When I read Stephen Hawking's book A Brief History of Time, and in particular where he describes how time can be thought of as another dimension with space comprising space-time, I started to imagine the implications this would have if the universe had an actual creator.

My initial conclusion was that if space-time is tangible and if the universe was created by an entity which must necessarily exist outside of the universe and that creator has the ability to observe all of the universe then all of the following must be true.

  1. The creator would be timeless from our perspective, being outside of space-time.
  2. The creator would observe all points in space-time simultaneously, including (assuming the historical accuracy of the Bible or Qur'an for a moment) the "original sin" event, the death of Jesus, the birth of Mohammed, and my death. In effect, the creator might be called omniscient about events in the universe.
  3. The creator would have dictated the nature of space-time so not only would it be observed but it would also have been designed. In effect, free will could not exist. An omniscient creator and free-will are mutually exclusive.

Unfortunately, I don't know how physicists really understand space-time. I know that it is theorized that traveling to some point in non-contiguous space-time is possible in one direction (the past) but probably not the other (the future). Logically, if the future does not exist then one cannot travel there. However, if the future does exist, if space-time is complete and tangible, then our speculations about determinism are no longer so speculative. The events which happen at any point on the space-time continuum are set and the idea of free will (however you define it) is obsolete.

I invite discussion and, hopefully enlightenment, from people who have a different perspective and a better education. I personally don't think that space-time is complete or that time exists in both directions based on what I've learned so far.

I wish I knew more about physics.
As with many issues debated, perhaps the lowest denominator is the sound answer;
"Time" is nothing more than another man-made creation. Nothing more.

As such, there is no future, there is no past, except for our memories and structures/devices that remain to this particular moment.
