Title: Recall that a raisin cake is sometimes used to imagine how an expanding universe Post by: killian on Apr 30, 2014 Recall that a raisin cake is sometimes used to imagine how an expanding universe behaves. Suppose you are in a uniformly expanding raisin cake, sitting on Raisin A, looking at Raisin B, 2 cm away from you. Raisin B is moving away from you at 1 cm/sec. At the same time, you observe another Raisin C, which is moving away from you at 3 cm/sec. How far away is Raisin C from Raisin A?
A) 2/3 cm B) 6 cm C) 3 cm D) 3/2 cm E) Impossible to say. Title: Re: Recall that a raisin cake is sometimes used to imagine how an expanding universe Post by: padre on May 3, 2014 BB
