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

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.
