A photon is the smallest piece of light. The ring is one photon trapped in a loop, like on the mass page. The black dot is a big trapped-light mass, seen from outside: you cannot see its hidden space, only the lines of space leaning in toward it.
Nothing pulls the little loop. The lines of space lean toward the missing space, and the loop just follows the lines it lives in. There is the same time between every picture, and the jumps get longer on their own. That is gravity.
Each loop wears dark green where space is squeezed shortest, the side by the mass, and yellow where space runs longest, the side far away. The squeezed side always wins, so the loop swings toward its dark green.
Inside the little loop the photon keeps going around at the same speed the whole time. Outside, the mass is only a dot; the little arrows under pictures 1 and 5 show how much space is missing at the loop’s near side and its far side. The near side is always deeper, and the pair grows as the loop falls.
