Question from a non-physicist

  1. Jun 14, 2005 #1
    Regarding the concept of light from distant stars "bending" due to the curvature of space caused by the gravity of massive objects:

    Question: can there be a cumulative effect? Could some of the objects we see as light actually be dopplegangers of nearer objects, their light carroming around space riding a daisy-chain of massive objects? Is this even possible?

    Theoretically, yes. In practice, I believe that this is difficult to observe or document - the intensity of these dopelgangers would be miniscule.

    You can get things like einstein crosses and other sorts of gravity lens effects that lead to double images of stars.
