How do we know that gravity is not an accelerated expanding of space?
It seems to do almost same thing to interacting objects.
“it’s complicated” comment is not welcome.

Can you explain more what you mean? Gravity tends to bring things closer together, so wouldn’t it be a contraction of space, if anything, rather than an expansion?
And how does that work when I feel pressure from the soles of my feet against the ground? Is there space expansion or contraction at the interface between my feet and the ground, and that’s why I feel pressure?
