Do you think that the world will ever end?

Absolutely for certain when the sun starts to die and expands.to become a red giant star. At that point, some billions of years from now it will engulf the earth. If it doesn't absorb the earth, it will certainly destroy all life on our planet.

To all beginings there must be an end. Just like a book.

Everything with a beginning must have an end.

yeah and it will come back
