Age of the Universe equation

In the beginning Big Bang, Scientists believe that the Universe became nearly it's current size in a fraction of a second - "According to the standard Big Bang model, the universe was born during a period of inflation that began about 13.7 billion years ago. Like a rapidly expanding balloon, it swelled from a size smaller than an electron to nearly its current size within a tiny fraction of a second."

Speed = distance / time
e.g. 100 km/hr = 0.028 km/second (approximately)

Speed of light = 300,000 km/second (approximately)

The expanse of the Universe is unknown but in order for the Universe to become nearly it's current size in a fraction of a second, it certainly moved much faster than the speed of light.

That kind of speed would break the laws of physics which limit speed to the speed of light except for the fact that the Universe expanded in a vacuum since there was nothing in the beginning (according to Scientists). If speed was limited to the speed of light then the Universe could easily be explained as 13.7 billion years old since;

time = distance / speed @ 300,000 km/sec

And we all know the Universe is very big!

BUT

As mentioned earlier, Scientists also say that the Universe became nearly it's current size in a fraction of a second. At that speed, time will surely not behave in the normal way.

A while ago, Scientists made a couple of interesting observations;

1. Clocks in moving objects run slower than clocks in stationary objects 
2. Clocks run slower in deep gravitational wells

In fact, Science has not discovered a law that prevents time from going backwards. If Einstein was right, time can go backwards if you can travel faster than speed of light. And at such a speed as the creation of the Universe, it could conceivably go backwards a very long time, making things appear a lot older than they actually are. Which throws a lot of doubt on the age of the Universe being 13.7 billion years in my opinion : )

We are all waiting with great excitement for Science to discover the truth!
