# What is the age of universe? [closed]

As we know at the time of big bang as mentioned by the scientist the universe expanded faster than the speed of light. So does it mean that at that time all the particles present travelled in the time and the age of universe is different from what we know today or scientist have calculated the age keeping the phenomenon in consideration ?

I don't understand what you are asking. Can you elaborate and/or rephrase? –  zhermes Mar 10 '13 at 3:23
we know that if we travel at 99.99% of speed of light we start to travel in time that is time become slower for us and it is said that at the time of big bang universe expanded at a speed greater than the speed of light so does it mean that universe also travlled in time and it's age is different –  Akash Mar 10 '13 at 3:27
Amidst of the many partial theories, Big Bang is also one of the suggested theories to describe the observable universe. Many others support the existence of such a singularity in the past. So, we presume time had a beginning at the instant of big bang because going into past is not gonna do so much good rather than confusion. So, it is just about 14 billion years old. I'm slightly suspicious that you're thinking about: "Would the expansion of universe faster than $c$ make us look into the past??" - I think you may find an answer in CMB –  Waffle's Crazy Peanut Mar 10 '13 at 3:34
How could it be that time didn't exist before the big bang as that thing which exploded would be in some space –  Akash Mar 10 '13 at 3:48
Your question is quite confusing, could you elaborate it? In the meantime I'll keep this closed. –  Manishearth Mar 10 '13 at 7:00
