Does light experience the time of the entire universe simultaneously or just from the beginning to end of its own existence simultaneously?
I assume that light experiences the past, present and future simultaneously of its beginning to the end. If this is true than does light experiences all the space it moves through as existing simultaneously? If this is true is there any way that you could view light in the middle of its existence and predict the future of its path and find out all its information, including the past?
What if the light gets divided, what happens to the information?
Could you create a conscious creature that only runs on light? What is space-time?
What is space made up of?
Your questions are a little off-the-wall for us disciplined physicists here. We would typicallly dismiss you out of hand. But, on the other hand, sometimes it's a little invigorating to have someone shake things up a little. The best I could do to help you consider some special relativity in the general context of your question is to show you a sequence of space-tlime diagrams. You really should google the space-time diagram topic and try to learn how to visualize the universe in the context of 4-dimensional geometry. It doesn't matter if you would rather not take such a description of the universe as actual physical reality (the earlier posts here have cautioned you against that).
Once you have a grasp of this 4-dimensional world you see how to represent 4-dimensional objects with their worldlines that extend along the 4th dimension (typically for distances of the order of 10^13 miles). The sketches below depict rest frames in which you see slanted time axis lines (they are shown here as the X4 dimension)--their slopes correspond to the speeds of the observers moving along their world lines (every observer, regardless of his inertial frame of reference, moves along his worldline at the speed of light. A worldline oriented at a 45-degree angle with respect to the rest frame corresponds to a photon of light.
Note in the sketches that as the time axis slants more and more in the sequence of sketches, the moving observer is going faster and faster. A very curious thing about nature (as revealed with special relativity) is that as the observer's worldline rotates clockwise more and more (for example) his spatial X1 axis rotates in the opposite direction so that the photon worldline always bisects the angle between the time axis and the spatial axis (of course this results in a constant speed of light for all observers, and it highlights the even more curious characteristic of nature that observers experience different cross-section views of 4-dimensional space-time; this explains things like time dilation and length contraction as well as some other intriguing phenomena).
Now, the X1 axis represents the space that an observer lives in at any instant along the time axis (the X2 and X3 axes are suppressed for simplicity).
Finally, to your question about a photon experiencing all past and future at once (not a ligitimate idea for us physicsts), the closest I can come to responding to something you seem to be driving at is to recognize that in the limit, as our traveling observer approaches the speed of light, his time axis and spatial axis would converge. This seems to set up the context for your question. So, to your question as we look at the sequence of the ever faster observer, what would be the meaning of the time axis and the spatial axis converging? You probably know that no material object can accelerate to the speed of light, so that's why you asked about what a photon would experience. If you ever catch one you should ask him. In the meantime, ask yourself if the photon's time axis and spatial axis are colinear.
