jimmyjammy Posted June 16, 2013 Posted June 16, 2013 (edited) there is a star say 60 light years from us. a day comes say when it expands into a monstrous red giant and we note it on earth. when do you expect the event to have occurred on a time scale on that star: (a)60 years earlier or (b)at the time we observed it on earth....if anyone feels it as (a) then let me know how we cannot even perceive it's size increase......ie., in the sky, it's size should increase so how can we not observe it?? sorry, the title that i put is wrong coz, i had to post somethin gin bio title with this title but accidentally put it even here and as i am new i don't know how to edit an already posted title Edited June 16, 2013 by jimmyjammy
