U.S national debt - US dollar on the verge of collapse?

Do you professionals have any insight on when will the U.S Dollar collapse? as scary as it sounds, I see on US national debt clock that the total US debt is $59.5 trillion and it is rising by $40k every second, therefore it is obvious to say that it is impossible to pay back the debt as it is rising more than being covered. so when will the US dollar collapse? and if this happens, do we all US residence become zombies? like the new movie coming out world war Z? due to all power & utilities become shut off, and no more production of food, therefore people will be killing each other to survive?
-Our dollar has no value and there isn't any gold to back our dollar...
-s&p 500 and other stocks are rising which i believe is a bubble for the billionaires to gain enough buyers to dump their stocks...
-gold has fallen which in fact is another bubble for billionaires and other institutions to buy gold at low rate
there are other facts which I will add as we go with this discussion.

It's unlikely that the dollar will collapse in the near future. Debt to GDP ratios have been unsustainable but are now coming under control. The US dollar is still the main reserve currency of the world.

Try reading a few facts and becoming informed, rather than quoting scenes from science fiction movies. Here's something to start you off: http://www.theatlantic.com/business/...-chart/265185/

The value of money is based on faith hence the terms fiat money. The usd would never collapse as long as people/the world has faith in the country. This faith are affected by many factors economic reports etc and their dominance in military is one of the most important factor.

The strongest and most advanced country in the world can do whatever they want.
