Could the universe expand faster-than-light during cosmic inflation?

In the cosmic inflation model is the statement that the gravity turned opposite in the Big Bang. That means the energy level in the very early universe was raised higher than its environment. The energy minimum was far higher than in the modern universe. And entropy was lower. It’s possible to eliminate the gravity wave that is the energy ditch by decreasing the energy level lower than the bottom of the gravity wave. Or lower than the energy minimum in the universe. Only time in history that this thing happened was the birth of the universe. 

When the universe turned cooler and the material formed there formed multiple gravity centers that formed the gravity turbulence. Before the first particles formed gravity waves traveled in straight lines. The growing entropy made space between those gravity waves. And turned them into curves. If straight horizontal gravity waves are possible that makes energy valley there particles can travel. That kind of gravity wave can pump energy to a particle that travels in it. 

The key element in cosmic inflation is somewhere in the history of the early universe: it expanded faster than light. And how that is possible. When material erupted from the Big Bang there was nothing that could slow that event. There is a possibility that the entire universe’s energy level including gravity waves were above the energy level around that event. So if the entire universe was at a higher energy level that means there was only a pushing effect that pushed material away. Because there was no scattering or other things and energy traveled in straight lines there were situations where nothing pulled energy out from that radiation. 

And then that thing made it possible for particles to cross the speed of light. Otr they crossed the speed of light in the modern universe. As we know, the speed of light is relative. It depends on the medium, where it travels. Without scattering there was no effect that pulled energy out from the first photons. So can the universe still expand faster than the speed of light. The fact is that if there is nothing outside the universe that means there is nothing that can limit the photon’s speed. Except only known photons come from our universe. 

And that means the gravity effect behind those photons slows them. But there is a theoretical situation where gravity can turn opposite. That situation is that the environment’s energy level turns lower than the energy level at the bottom of the gravity wave. This effect eliminates gravity. So, that means that in the very young universe gravity turned opposite. The reason for that is that the universe’s entire energy level was higher than its environment. And that is the only known theoretical situation. 

If we think possibility that the universe expansion causes gravity wave ahead the universe, that requires quantum field outside the universe. That means the energy ditch surrounds the material bubble that we call the universe. If the energy ditch is deeper at the front of the structure it pulls that structure forward. If there is an energy ditch only at the front of the structure, the force of the energy ditch at the back of the particle will not disturb its acceleration. When a particle or any other structure moves it binds energy into itself. That thing causes an energy ditch at the front of the particle. The energy ditch will fill sooner or later. And that causes that particle to slow. Differences between energy levels behind and forward of the particle determines its speed or acceleration.
