Question

Quizplus · Accepted Answer

Gravitons are hypothetical elementary particles that mediate the force of gravity in the framework of quantum field theory. If they exist, every object with mass or energy would exchange gravitons with every other object, regardless of the distance between them, as gravity has an infinite range. This means all pairs of objects in the universe, including those listed in options A through D, would exchange gravitons.
