The law of universal gravitation states that any two objects in the universe,
without exception, attract each other.
When you think about it, that means that there is a force of attraction
between the lint at the bottom of your pocket and the smallest grain
of sand on the beach on the other side of the farthest planet of the
farthest star in the farthest galaxy on the other side of the universe
from us. The force is too small to measure, but it can be calculated.
