3.1  relation between expanding of universe and expanding of Galaxy's

Universe is a huge space.It is the collection of Galaxy's.Galaxy's are collections of heavenly                bodies. Heavenly bodies are nothing but stars sun moon planets and etc.In directly the place where we live.There are number of Galaxy's in space,One of them is our Milky way Galaxy.as we see now all the Galaxy's are far apart from each other.But this was not the case millions of years ago. Millions of years ago all the Galaxy's were very close to each other.As years passed on,the Galaxy's started to move away from each other.Not only the movement of galaxy's was taking place but eventually we got to know that even the galaxy's were expanding and this expanding was proportional to rate of  galaxy's moving apart.Many scientists say that this expanding  is for ever.where as some other group say that the expanding is only a certain period of time.After reaching some maximum point ,they say that the Universe will Collapse,and every thing will have its beginning again. as of now we need to worry because this might take place millions of years later.And the predictions are that by this time even  our sun would have died.
