Spacetime and the universe's curvature.

The photon could be the shortcut through spacetime from the past to the future or the present. 

Because the Big Bang event formed all known energy the past is at a higher energy level than the future. The universe's expansion is the thing that decreases the energy level all the time. 

If you cannot reach the speed of light, you cannot reach energy stability. In energy stability, a particle gets as much energy from its environment as it releases. And the only known particle that can reach energy stability is a photon. In the model, the photon is the particle that travels between the energy wave and the energy ditch. 

In some models, the past is the thing that transports energy to the photon. If we think that a photon is an extreme practice that travels with the speed of light. That means that. On a photon's shell, all other phenomena are also extreme. So because the energy level in the past is higher than in the future, the past will pump energy from the past through photons. 

Photon has two forms. Particle and wave movement. In the wave movement form photon looks like some kind of tape. The wave movement form of a photon is like a flat tape of spaghetti. And if we are accurate the back of the photon's wave is in the past. We can think that in the form of wave movement photons travel a little bit faster than in the particle form. And maybe the particle form photon is like a wave or stretch rather than a yarn ball. 

So if the past pumps energy through photons, that thing is one of the most fundamental advances in physics. That means photons are channels or shortcuts through time where energy travels faster from the past to the present than otherwise. 

Above: Universes expansion is the thing. That turns quantum fields weaker. Which causes the material vaporization, or particles turning into wave movement. That means that one version of the time is the universe's expansion.  When energy travels out from a material, the material turns old. 

The time dilation is a much more complicated thing than we can even imagine. The time dilation is the thing. That slows energy transfer out from the particles. Things like the gravitation field's strength, speed, and electromagnetic environment are things. That affects the speed of energy flow out from the particles. The fast energy flow causes more damage than the slow energy flow. 

The thing that depends on the aging of the particle is the difference between the particle's energy level. And its environment energy field's energy level. If that difference is very big, it causes energy to flow out from the particle at a very high speed. If that energy flow is too fast that effect rips particles in pieces. 

The kinetic energy is the thing that connects to the speed. When a particle travels fast in an electromagnetic field. It collects energy into it. The reason why a particle will age slower is this a fast-moving particle collects more energy into it. But all particles turn older. The reason for that is that sometimes. They release photons. When energy moves to the particle its speed increases. And when energy starts to flow away from a particle, its speed decreases. 

The only known particle. That can reach the speed of light in a straight universe is a photon. The gravitation can cause time dilation. In that case. Gravity center packs electromagnetic fields around it thicker. That means. Energy flows out from particles slower than outside the gravity field. The reason why the particle can reach and cross the speed of light in an extremely strong gravity field is this. 

The gravity moves fields to the gravity center. The speed of light depends on the medium. That means the electromagnetic field that travels to the gravity center with the speed that is the speed of light can transport particles faster than the speed of light outside the effect area. In the event horizon, all particles travel at the same speed. So the speed of light depends on the speed of the environment. Same way speed of time depends on the environment. Or, it depends on the differences between energy levels between particles and their environment. 

Do you know that your head lives longer than your feet? Observing this thing requires that we stand in the ultimate gravity field. Or our height must be hundreds or thousands of kilometers.  And if we want to observe that thing without the accurate atom clocks. We must be even billions of kilometers long. 

If we stand on the black hole's event horizon, the event horizon pulls the energy fields through us. The black hole would pull energy out from our feet. And that means we will get more energy to our heads than to our feet. Normally, people say that the gravity field causes time dilation. 

Things like speed and outcome energy cause time dilation. So, time dilation is an energy interaction. Energy flows to the particle or out from it. 

And that opens new types of ideas for time and its relationship with material. When energy travels to the material, it turns older. And when a particle receives energy. It turns younger, or its aging turns slower. We can think of a situation where energy moves out from a particle and forms space or pockets into it. 

And that causes horizontal-, or internal energy waves that cause more energy escape. That thing turns material and particles older. When energy travels back to the particles they get into young again. But for reaching infinity the particle must reach the speed, where it releases as much energy as it gets. 

But how your head can live longer than your feet? The simple answer goes like this. The reason for that is time dilation. Time dilation means that time is slowing near the gravity center. That means time moves slower on the feet. And that causes the effect. That the head lives longer. We can think that our head goes ahead in time. But that is too simple and there is a missing logic. So let's think about time dilation and energy flow in the object where time moves at two speeds. 

The past is at a higher energy level than the future. 

And if we use the model where time is like flow that travels against us, we can see that we are leaning forward in time. The difference between time in our feet and head is purely theoretical, but we can measure time dilation in GPS. The atom clock in GPS satellite works faster than the clock runs on Earth. But why that is not otherwise? Why cannot we say that our feet live longer, even if, time is more dilated on our feet? The fact is that we are standing in the same gravity field on our feet. 

The thing is that the time dilation is the energy flow to the gravity center. The energy flow that takes us with it is the thing that pumps energy to atoms. But then we must realize one thing. The future is at a lower energy level than the past. That means if our feet are in the past energy flows to our heads faster than in the space around us. That thing happens through the atom's bonds. Those bonds are like small wormholes. And they can transport energy faster than the environment.
