www.9822.com，The universe will expand,then it will collapse back on itself,and then it will expand again. It will repeat this process forever. What you don't know is that when the universe expands again,everthing will be as it is now. Whatever mistakes you make this time around,you will live through in you next pass. Every mistake you make...you will live through...again and again,forever. So my advice to you is to get it right this time around,because this time...is all you have.
