The plane represents spacetime. As for how it works from an underlying perspective (intermediary particles, whatever else), that's still a great unknown.
Practically, we understand that mass distorts spacetime. Light travelling in a straight line will continue to do so, however that straight line would appear curved to an outside observer
There's nothing here!
