Marcus, i'm back, now waiting for offers from college. --- last night, i re-mused about the balloon model and expansion of space (Java link:http://www.astro.ucla.edu/~wright/Balloon2.html) On that expanding balloon, a galaxy has a constant coordination; only the distance between them expands. the light that travel between the galaxy is lucky to gain interest on the distance it already travelled(it travels 1ly and that 1ly expands to 1.4 ly), so the light can travel faster than c. but what about the distance untravelled? Didn't that distance also expanded? put it into the bank analogy, it's like the interest of the savings(distance already travelled) makes more money, but the interest of the loan(untravelled distance) cuts off that money. shouldn't it balance after all?
