Einstein’s light cone and five-dimensional spacetime.

“Light cone in 2D space plus a time dimension, more commonly referred to as ‘space time’” (Wikipedia)

The light cone introduces the model. That time focuses information on the hypersurface of the present. But why can't we see into the past or future? Entropy is introduced as the reason for. Why can't we see the future? Or to the past. This means that entropy scatters information into such a small mosaic and twists it. That information exists. But. We cannot collect it into a form. That. We can use it. 

Term spacetime, or. Space time. Means the space and time. “In physics, spacetime, also called the space-time continuum, is a mathematical model that fuses the three dimensions of space and the one dimension of time into a single four-dimensional continuum. Spacetime diagrams are useful in visualizing and understanding relativistic effects, such as how different observers perceive where and when events occur.” (Wikipedia, spacetime)

There is a connection between time and space, and Einstein explained that connection by describing time as the fourth dimension. And maybe we should say that the time that travels forward or to the future is the fourth dimension. The arrow of time, as Eddington explains, states that when time moves forward, the arrow of time moves time backward. 

The arrow of time introduces black holes as a place where time appears to travel backward. That means that black holes can be seen as things. That pushes time forward. Time dilation causes that. When. The escape velocity turns higher. Than. The speed of light, time starts to travel backward. 

Above the gravitational pothole is the model of spacetime near the gravitational center. The black hole should turn the walls of the pothole. Through. Each other. That means its gravity field turns information around like a magnifying glass. 

Three versions of our point in relation to the light cone and the metasurface of the present. Each of those models is based on the model that there are five dimensions. Three of those dimensions are in space. And two are in time. 

1) If information focuses on the hypersurface of the present, it can act like an electromagnetic field. If information forms. Some kind. Of “electric arc”. We can be in a bubble. That denies us. From. Seeing the future or the past. That information focus that is behind or in front of us is so “bright” that we cannot see through it. 

2) Another model is that. We aren’t exactly on the information focus. If. We are in a place. Where. The information focus is behind. Or forward to us. That means we cannot see through that point. But the interesting model is that information should. Turn around. When. It travels through the metasurface of the present. 

3) The entropic model is that. Every single particle, or object in the universe. Are on. Its own metasurface of the present. Or, maybe we should say that the metasuface. The present is a complex entirety of structures. This means it's full of information focus points. And those focuses cause very high entropy.  

But. Then we can. Start. To. Think. About. Light cone. This model. Explains that the information focus is at the point of the hypersurface of the present. But are we on the hypersurface of the present? That is an interesting question. The idea is that information focus happens on that hypersurface. When time arrows touch each other, that event forms a structure. That is like when a magnifying glass focuses sunlight. Sometimes it is suggested that the material and the Big Bang formed when the light cone touched the hypersurface of the present. But why can't we see the future? The answer can be in entropy. And another thing is this: Materia is like a frozen electric arc. 

When we think about time dilation. And the hypersurface of the present. Time moves faster. At 30 cm above sea level. We can think. That. If the focus that forms when the light cone focuses information on the hypersurface of the present, the geometrical model of time in our universe is a ball. We are like in the middle of a giant electric arc, which could describe the geometrical model of time in the hypersurface of the present. There are actually three models of time, or how information focuses on the hypersurface. In those models, we are in the middle of a giant bubble, or we are not precise in the metasurface of the present. 

That means there is. Some kind. Of. Time focuses information behind. Or/and forward of us, if we think. That we travel in space from the past to the future. That focus. Denies us. To see the future. Another model is that the hypersurface of the present is not sharp. That means the universe is full of focuses that focus information from the future. And from the past. This is one of the attempts.  To introduce the nature of time or the geometry of time.
