Science has started to question the role of the observer in the expression of reality--the two slit experiment wherein the result changes based on whether the photons are being observed going through the slits or not, is a good example.
So I postulate that God (for those of you who believe), or 'the universe in general' (for those who are more concerned about the mundane aspects of reality), is the ultimate observer. All knowing and all powerful is the same as everything in a reality which is only real when being observed.
Call it 'social induction'. The world we live in today, tech etc., is the result of social induction. Our knowledge and education cycles act like an induction coil, sort of reinforcing the motivational factors of society until you come up with things like induction coils and computers. It's a sort of knowledge singularity created from induction/education. Stop the education--the power--stop the induction. Without education, our tech would collapse like the magnetic field in induction does when you turn off the juice.
Unnecessary additions to a story tend to bother me. If an author puts something or someone into a story, it should be done for a reason. If there is no reason, I find it annoying.
One lie I find annoying in modern fantasies is when fictional worlds are forced into our reality by making the monsters and magic a total secret from the rest of the world. I guess I can understand the desire to bring vampires and fae and whatever into our world, but it is fiction after all. Why do these modern fantasies need to have anything to do with our world?
Some authors (Laurell K. Hamilton) write about worlds like ours, but not--where monsters are real and everyone knows about them, if not the details. These worlds skip the unnecessary lies--the ones which rely on fictional secrets to keep the masses from panicking. Now the unnecessary lies are sneaking into TV and movies. Maybe they were already there. Maybe I'm the only one in the world who finds this annoying.
On the other hand, if I ever write a book about vampires and werewolves and whatnot, I might throw in some quantum theory and a bit of magical thinking (is there a difference?). Everyone in my modern fantasy would create and live in his or her own universe, and they would overlap where the reality perceived by each person matched. No one would notice the differences unless they had training.
We tend to think of time as an element or dimension which can be separated or filtered from the general idea of space. Conceptually, I believe that is true, but as a fundamental law of the universe, it doesn't seem complete.
There is evidence that time travel is possible, or that time can be ignored by entangled particles, and it is these two vaguely related ideas which I have combined into my own pseudo-scientific theory called "Temporal Entanglement".
If we make time an essential element of space--not just time, but that time which happened in that space--then time is unique to location. It's possible the location could be as small as a photon, or maybe within our own minds.
A time machine would have to tap into the entangled properties of space/time, or it wouldn't work, like that thing that doctor uses. The good news is the machine wouldn't go careening off into solid rock or unexpected vacuum because it moved in time, but not in space.
I'm sure I had a better point to make when I started writing this. . . .
An argument on the nature of reality goes something like this: Reality is created by observation. Without observation, there would be only a cloud of probabilities--chaos.
An alternate argument would be that reality is not created, but interpreted, and we see not reality, but a dim and filtered version. Chaos is only chaos because we do not and possibly cannot understand true reality.
In the first, we define reality by what we know. In the second, we define reality by what we don't know. In both, we define reality.
