The universe is a finite entity it had a beginning and one day it will go out of existence.
Before the universe began there was nothing but this nothing had to have a potential and the potential had to be finite or it would have stayed a potential forever.
Some way the potential produced a single quantum space-time pulse of minimum size and duration with everything necessary to evolve into a universe like ours.
When it goes out of existence it will again become a nothing,with no potential and it will never occur again.
time and space exist in two forms- in perfect form and in self destructive form. we are now in self destructive form era because of the wrong choice of men.to make the explanation short-the perfect form is in perfect circle form - a form unaffected by time and it is infinity. the self destructive form is like a coil with tail at any side ,the pull of gravity make a circular line that connect the circular line from the surface to the center of circle.if only men did not commit sin,we are still in perfect form era but because men become more evils ,the whole world in in self destructive form system!
