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...
I am not well versed, and my answer can be dismissed here (and even gentle corrections would be greatly appreciated).
I would split the difference. Stella can claim SHE is at rest, but the ship she is on is not. Terrence can also claim HE is at rest, but the Earth he is on is not...
I am a rookie at best, so please forgive me if this question seems simplistic or its answer painfully obvious. But...
If R1 is in motion (at a tremendous velocity) as it approaches P1, and R2 is waiting, therefore at rest, at P2: would the relative gravity have more effect on the light...
