Could it be that there is no gravity, and what we perceive as gravity is the pressure from the expanding universe?

So how would that explain the fact that spacetime is curved in a very predictable manner in a clear relation to the mass of an object in spacetime ?

[axilmar]

Perhaps spacetime curvature is nothing more than the gradual stopping of the universe expanding when mass is present.

Isn't that gravity is just a result of clock tick rate is slower if you are closer to some matter?

[axilmar]

I believe that is backwards...time changes due to gravity and not vice versa. It's a misunderstanding propagated in the last few years through misconceptions.

It makes so much more sense that there's no Dark Matter.

[gtech1]

around the turn of the century many ideas were floating around in order to explain unexplainable phenomena. It took Einstein and Quantum physics to radically change the worldview and make sense, while make-shift ideas were discarded.

I suspect the same will happen with Dark Matter
