Question about Gravity effect across the Universe?

I was told the gravitational effect from a piece of dust would be felt across the Universe (obviously as long as its had the time to travel that far).

That got me thinking, physics doesn't generally like infinities. Would the gravitational effect eventually divide down to the Planck length, thus going no further?

Ex. If I wanted to build a bridge across the universe with bridge segments starting at 1 meter, then the next being half of the meter, then half of that half, and so on... eventually I would get to the Planck length and my bridge would not be able to continue.

As we learn more and more about String Theory or Loop Quantum Gravity, could my idea be correct?

    You got it right.

    If you check functions about those infinite adding half expression you will find a limitation of its value. Like a border value it will never grow bigger than no matter how long it takes. So you are right.
