Space, our universe, is lumpy. Matter causes space ( spacetime ) to curve. The denser the matter the greater the curvature.
When we ( humans ) are in space with no gravity present, we are referred to as being in a state of free-fall.
Now, starting from here, what if instead of saying we’re being pulled to the center of gravity we say we are being pushed in, by spacetime ( perhaps by way of gravitons ). As a result of displacement.
I say this because, the model of gravity as described by general relativity makes me think of putting a basketball in the ocean and pushing it under water.
If you think of the water in the ocean as spacetime, and the basketball as a planetary body, perhaps you’ll begin to see my point.
The basketball displaces the water and therefore pressure is created on the surface, pushing all the way through to the center. With a denser ball, say a cannon ball, you don’t create greater pressure but you can go deeper without being crushed.
Similarly a black hole’s density allows for it to push deeper and deeper into the fabric of spacetime, via extreme curvature. Likewise, the pressure exerted by the ocean on the basketball could also be imagined as spacetime pressing in to fill the void created by a massive object. And that mechanism pushing us to the center of gravity? Could it be the elusive graviton?
Taking all of that into consideration, the geometry needed to describe this immense curvature of spacetime seems to line up with the concepts described in quantum mechanics as well as the existence of a graviton particle. In essence, when you go from describing gravity as pulling to pushing – the idea of a graviton acting as an agent of spacetime / gravity makes a lot more sense.
To me anyway.
Perhaps, this may even a way to make sense of the fact that the universe appears to be expanding and an accelerated rates. Without the need to Dark Matter/Energy. We’ll see.
To be continued.
