Mass bends spacetime via what force?
how gravity of cosmic bodies warps spacetime

Granted, this kind of visualisation makes it harder to explain how smaller bodies orbit the bigger ones, so that's where the trampoline analogy might still be useful. But this, in my opinion, is how the effect of gravity on spacetime should be visualised.

My question is, what is spacetime? Everything else about our existence seems to be streams of particles. There has to be a physical connection, it isn't some metaphysical mysterious force. We have streams of electrons and streams of magnetons everywhere. The magnetic field is influenced by gravity, streams of magnetons exit the northern pole and reenter at the southern pole. I would think this would indicate that spacetime is also streams of a particle mass (gravitons?) flowing in every conceivable direction, thus being partial blocked by a large object. For a person standing on the planet earth, this would mean gravitons are exerting a greater pressure from above than below. We see this phenomena with neutrinos passing through a very large object, many pass through but some are absorbed or captured by the large object. Gravity can exert its influence for thousands, if not millions of light years away. If everything else is particulate, it would stand to reason that spacetime itself is also a particulate.
Just my uneducated observation...

Nice vid.
Gravity is a strange thing. Not sure it is really understood.
If we knew how it worked, we could make gravity motors in the same way we make electromagnetic motors and dynamos.
I've got as far as understanding there's this quantum foam made from pairs of particles that appear and disappear. Positive particles tend to "disappear" into the nucleus of an atom just like positrons. So that generates a flow. A magnetic field is the positive and negative virtual particles lining up.
It's the lack of an equal or opposite force that confuses me. There is something fundamental we are missing. A force that only acts one way is, frankly, bizzare. Gravity, or whatever it is, is the glue that makes everything work effectively. But what the hell is it?
Magnetic fields follow the one over distance cubed rule and are bipolar (due to positive/negative charges), while gravity is one over distance squared and monopolar. Nuclear forces are even higher powers but don't go beyond the atomic nucleus. But there are repulsive and attractive forces.
Perhaps our folly is in viewing gravity as a force (and by "force" we mean application of energy). As I described in my previous post, the attraction may be solely to time dilation. Mass slows the flow of time down near itself, and this discrepancy in the flow of time causes objects to "slide" from fast-time space to slow-time space.

Gravity pulls but pushes at the same time, that's why the moon hasn't crashed into the Earth.
