There is only one chance to understand time: We have to think with more than our four dimensions. This is only possible, when we compare our 4-dimensional world with a situation, that has fewer dimensions. Also Albert Einstein did it, when he thought about riding on a light beam. Now I go a step further and think about a photon's life and how it is experiencing our space-time? The isomorphisms between a 3-dimensional and a 4-dimensional world can be very helpful for our understanding and imagination. With that help we can make assumptions about a 5-dimensional world.
So my theory about the nature of time is as follows:
Time is proceeding with the speed of light, the maximum velocity on principle, and the expansion takes place in a continuum with 5 dimensions at a minimum. Time is a perpendicular dimension to our three space dimensions, and its velocity is: 1s = 300.000km/sqrt (-1).
This is the reason, why we cannot see higher dimensions and why we have this strange experience about time. It flows, and we cannot go forward or backward. This experience is equal to the experience that photons might have about their moving direction.
The following short story describes this idea metaphorically.
“The Flashlight of the Photographer”
At midnight a photographer with his flashlight is making an outdoor photo of his wife.
At this moment billions of photons are spread out. Most of them will pass his wife and start an infinite journey to space. But some of them will hit the face of his wife and will be reflected to the sensor of his camera, where they will be changed to electrical impulses and in summary to an image of the photographer’s wife.
Albert Einstein has shown that fast moving objects get two experiences while observing their surrounding:
1. In other initial systems time seems to proceed more slowly.
2. In the direction of the movement distances seem to be shorter.
These effects are equal for the initial system of the observer as well as for the observed one.
That’s why it is called the “Relativity Theory”.
In case of photons the speed of the movement is the speed of light, a maximum on principle in our universe. So time is standing still for photons and space has no elongation in the direction of their movement.
But if photons would be intelligent enough to describe their experience of their movement through space, they probably will say: “It seems that we are in a kind of motion, but we do not know how fast, and we have no idea where we are going to. Neither can we go more slowly or faster. But after all, we know where we have been already.”
And then we will realize that our experience of time is very similar to the experience of their movement.
Could it be true, that our time is nothing else, than a movement through a 5-dimensional space with the maximum speed on principle, similar to a photon’s journey. No wonder why we cannot see any higher dimensions — similar to photons — and why we have freedom of motion only in three remaining dimensions.
In case of the photographer billions of photons are spread out to produce an image in his camera. If some of these “intelligent photons” start to reflect their own life, where they come from, the meaning of being and existence, even about their sense of life, they surely never ever will suggest that a photographer has created them in order to abuse and destruct them for an image of his wife.
Is it possible, that the big bang was something like a higher dimensional flashlight photo?
And while we surge for answers, we know that we are as stupid as a photon, when we try to understand the meaning of a big bang.
