It is a different view of gravity how it came about and is the only theory to explain how gravity works. The mechanics of Gravity are never described in any other theory.
The simplest answer to any theory according to OCHAM’S RAZOR is likely to be correct.
The main difficulty most people will have is not appreciating that all materials, however dense including the human body are empty space. If you can accept that as fact, it is so, then you may see also that space must have always existed even to the full extent of what is observable to telescopes today. Thus empty space which we have always considered to be nothing is in reality all that has ever existed and must de considered as the main building constituent of everything and energetic motion of space creates everything we see, feel and hear about us . The energy is provided by the spin of space by which the pull on space, carried on eternally creates a permanent particle.
This pull on space is what we call Gravity, only “New” Gravity because we are explaining pure gravity in a new way. That empty space between our ears is not as humiliating as it used to be, is it !!!
