Homework Help: Stars and the Galaxies

Posted by Sara on Thursday, March 4, 2010 at 7:32pm.

if alpha centauri were to all of a sudden disappear, we wouldn't knknow 4 another 4.3 years. How come? Why would this be the case?

would this be the case because its really far away from us and it's 4.3 light years away. So if it suddenly just vanished out of sight, then it would definetly take 4.3 light years to get back, because that's how long it would take its light to travel.

please correct me if I'm wrong, and list any other info, thanks - by more info, i mean info that you know from the top of ur head, please no links, thanks
