End of the universe ?

If I ask you the point of beginning and the end of the plannet earth, what would be your answer. What I think is it could be anywhere as it is a sphere. We do not have the total knowledge of universe. But my personal opinion is that it too should similar sort of thing where you cannot say an exact point of beginning and end. However, we can know the size of the plannet earth which we cannot know that of the universe. If you can go beyond a certain point then it means that you have not come to the end. Going beyond that point is still traversing the universe.

If the universe is end any time up to the end of the universe we cant live if we live at that we cannot do any thing. yes there was an end of the universe then it will take lot of time , it is not easy to stop the universe no creature will live each and every thing will collapse nothing was there i don't like to end the universe i want to born again and again. we don't know the future we cannot stay for tomorrow, and we don't know the tomorrows time and fate of ours.So leave the tomorrow, enjoy the today only.

This is a good question that is hard to answer. I do try to believe in a higher power such as God who created all of this. Supposedly the world will meet its end one day. It does seem though that the universe should go on forever. But at one point the sun is going to burn out supposedly. I guess with so many millions of years or more of burning I guess it would deteriorate at some point. Sometimes I like to think of these things but I don't think the universe is reaching its demise anytime soon. We can only hope,right?
