What is Gravity?

Please join me on this journey further into the thoughts about Unity.
As with every theory, you are welcome to disprove it and save me some time.
Now, where do we start looking for gravity? Isn't it everywhere?

Our journey starts on our Blue Planet. Here we feel gravity everytime. But we want to find out what is beyond. To do so, we travel away from Earth, out of our solar system into our galaxy - the Milky Way. Here, every bright dot you see represents many solar systems. The diameter of the Milky Way is about 100,000 lightyears across. We are located approximately here - shown in this circle – which is about 1,000 light years across.
Our Galaxy then is nothing but a small bright dot on this map of Super Clusters. And now, in another step further away from Earth we see that even super clusters shrink to small dots on your screen when we're looking at our local universe. This is as far we can see.
From here, Earth is really really really small, but there is one quite special thing about it: Earth is exactly at the center of the universe.
This universe is also called our 'Cosmic Horizon' - a 'bubble' as big as far we can see.

Remember, we are still asking "What is gravity?"

In this Cosmic Horizon, two things awaken our interest:
The fist is Dark Matter: undetectable but said to exist, glueing together large scale super clusters and preventing matter from drifting apart, and the second is
Dark Energy: also undetectable but said to be the driving force for the universes expansion.

At this point I'll use the so-called Cosmic Density Pyramid as basis for my further discussion. It shows the distribution of density in the universe which is explained in the book 'The View from the Center of the Universe'. According to our 'current' paradigm, matter and also dark matter create gravity. Gravity then is the reason for space warp. On the other side, Dark Energy is said to create anti-gravity, or at least something that causes the universe to expand.

This current picture is missing two vital parts. What creates time and space? And what creates matter itself?
So let's start again, this time at the origin.
Something creates matter and energy. It also creates space and time. All these, matter, energy, space and time can't be separated. They all depend on each other.
Then we come to gravity and ask: What creates it?

As quite often, it isn't a specific answer that will help us to progress, but a better question. So we ask 'What is first? Gravity or Space Warp?'
Next to the top part of the cosmic density pyramid (which represents matter) you see a 2D model of 3D bent space. Our sun in the middle of our solar system creates the most gravity which equals the most space warp.
Now, forgetting about Dark Matter for a moment and plainly looking at the effect of it on large scales, we see a similar space warp - but without matter.

At this point, why should we assume that there is something invisible and undetectable causing this space warp? A more obvious assumption just is: Space can be warped with or without matter. That means, the statement that 'mass creates gravity' is not the whole story.

If the universe is warped even without matter, then this would explain the effects for which Dark Matter was invented for – but in a much more logical way…

It explains why matter like galaxies in a galaxy clusters stay together and do not drift off.

Imagine a Large-Scale Space Warp without matter being warped like this. Our solar system (of course a lot smaller) shows similar space warp but with matter. Completing the puzzle, our solar system might be only a dent in a dent, like this.

Same way but in another scale, galaxies might be dents in a larger dent.

If this would be true, there is no need for Dark Matter anymore.

Let's go back to the Density Pyramid, we didn't look at the bottom part of the pyramid yet. Dark Energy. The effect we're trying to explain with Dark Energy is expansion. Following our argumentation, the only thing required for expansion is a reduction of space warp.
This is like a blanket with a lot of wrinkles in it that you are straightening out.
We assume: Expansion might be a reduction of space warp.
Back to our puzzle so we can complete the remainders. Space can be warped with or without matter. So matter doesn't create gravity but something else does.
Also with this new understanding, it is much more logical that space warp is the resulting force and gravity is just a quality of it.
In the same way, the characteristics of dark energy (expansion) is just another quality of space warp.

At this point, the question of 'What is Gravity?' is not fully answered but got somewhat secondary.
Another, more powerful question arises - looking at the strong connection right here - which is: 'What is Space?'
