Gravitons and Relatvity?

  1. Jul 8, 2004 #1
    It must be wrong to think of gravitons like air molecules that have the free space to move in any direction, because if a wave of gravitons could move side to side, they could effectively ‘miss’ attracting some small particles. So they must behave like a complete solid wall of particles.

    But then as the waves move further away from their source, they must split up/stretch out and so the gravitons have gaps between them?

    Also, is there anything in general relativity that says gravity does not stretch out infinitely? If gravity is space curving (curved geometry) then the geometry must have a start/end for the curve to begin and end?

    Gravitons would be much denser than you suppose. Notice that sunlight - photons - manages to illuminate every square inch of earth, even though we're 93 million miles from the photosphere. Gravitons should do at least as well as that.

    And no, general relativity doesn't prescribe a boundary for curved space. A potato has a curved surface, but that surface has no edge.
