With every improvement of measurement we are able to determine the age of the Universe more exactly. I just wondered how much and what means it would need to narrow the range of age so that it would be possible to determine the exact date of the Big Bang.
I know that this would take a lot of assumptions for the sake of simplicity - I am just curious; this being said: let us assume that all current theories hold and no new side effects or new theories would evolve.
I read this post and some physics articles about the matter, but my question focuses on the accuracy gap between our current best telescopes and the accuracy that would be needed to narrow down the age to "24 earth hours".
The age of the universe as we know t is very hard to determine. Current estimates put down the age f universe to 13.5 billion years +/- 0.8 billion. This is a huge a margin of error when compared to the margin or error you speak of.
Also it will never ever be possible to measure the age of universe because:
The universe started according to the big bang theory and if we take it as true it gives us a near infinite radiation density. We could measure the expansion and try to estimate the age but it is still hazy as we have no way knowing the initial density of the universe.
There is always an uncertainty in any measurement. and measuring something so far away(The edge of the universe) will have a lot of uncertainty.
These measures of today may still have a huge margin of error but they are the best we have till date. And to narrow the error down to about even a few years would take us a lot of time and tremendous development in technologies. So basically we have a very slim chance of determining the precise age of the universe in the foreseeable future
