Physics, Astronomy & Cosmology / How Do We Know The Universe is 13.8B yrs Old If We Can Only See The Observable ?

Hi, I'm Sheepy how are ewe ?
As a keen Astro photographer I am proud to have the record for the most pretentious "selfie" of all time.
Trust me, It was rather hard holding the selfie stick for this one !!
In the above non-doctored-bona-fide-true-to-scale photo I was contemplating on the age of the Universe. How can we know it is 13.8 billion years old if all we can see is the observable Universe ?
How can ewe deduce the age of the Universe if ewe can not see the unobservable Universe in all its non viewable grandeur ?
**As a firm believer in empirical study I sneaked into my neighbour's house at 3am this morning and he gladly did not resist when I chloroformed him. I strapped him to a firework with a piece of foil (solar sail 2cmx 2cm) attached and launched him. I told him that all he need do is hold his breath and to not let go of the end of the tape measure and stop watch, Whilst we await the data can you answer the kweschun ?

** The Naked Scientists does not condone this type of behaviour. Sheepy is a trained sheep. I mean, who in their right mind would use a solar sail of 2cm squared ? we all know it should be at least 2.5cm !!
