It can look dumb, but I always had this question as a kid, what physical principles would prevent this?

Gravity waves doesn't go faster than light though?
I'm going way way out against the standard model here.
No spacetime, no dark matter or dark energy, not even photons.
Just a '3D big ball of yarn single object universe'.
If light is a 'turn of the "stick"', then gravity is how 'the "sticks" are binding the atoms together'.
And so there would not be any gravity waves.
And any measurement of them would then have nothing to do with gravity.
And gravity is instantateous, and if not, really really fast or planets and stars would slingshot themselves out of orbit.
Iirc from the 2 YouTube videos I watched light can theoretically bend thanks to gravity, black holes anyone?
Space bends due to gravity. Light continues in a straight line through the now non-linear space, thus appearing to bend.
Gravity bends spacetime, light always goes in a straight line, bent spacetime means straight lines can be curvy. That all checks out.
But none of that helps you with FTL communication.
