1. Every beginning has an end!
The world began one day and anything which begins must end one day.
2. Big Crunch theory...
Scientists believe from observing the red shift in distinct galaxies that the universe is currently
expanding. According to Einstein theory, the universe has a finite volume and finite number
of hydrogen atoms. At some time in the future, no one knows when, the expansion of the
universe would stop. The galaxies which are now receding from one another will start to
approach towards each other and finally they will start colliding with each other. As there are
more than 100 billions of galaxies, billions of collisions will occur one after the other - that is
how the scientists believe in the occurance of the Doomsday. The Holy Quran confirms it.
