Our Universe-beyond

Much as it was portrayed a century ago, the knowledge of our physical Universe keeps changing. Then it was said that the Universe was all encompassed as an egg feature and all that was seen in the sky was the whole of the Universe and stationary. SInce then science has shown a lot of expansion really describes the Universe overall and it has no center.

That still holds today. There may be even more, in accordance with efforts to get a grasp on its size. Many observations and gauging and theories suggest there is more beyond the 'observable universe', which was brought into being by the 'era of decoupling'.  It is said for the observable universe that there are 10 sextillion stars. According to some scientists, the Universe started with such energy that it expanded faster than the speed of light. Those particles, materials and radiation  remain beyond the range of detection because they are beyond the 'observable universe'. Light information from that distance has not yet reached back to our range of detectability and hence remains unknown and unestablished, i.e. that distance has not been breached by light and its speed. It is an undetected fragment of our Universe beyond sight. What shapes or structures exist out there, unobserved?

 If there is nothing more, then what would be found? If it is that the light of the Universe does not reach into what lays beyond, or the starlight and sources die out, what can be detected? Just impenetrable, endless blackness beyond the frontier of the Universe or universes.

There is, reportedly, one star that is still registered as being older than the Universe, possibly by 800 million years and is 190 light years from Earth. It was recorded several years ago through the Hubble Space Telescope in 2013, although it has been known from 1912. That would be listed as HD140283, said to be 14.46 billion years old. It is composed largely by hydrogen and helium which are the first elements known. Then one has to consider if the star is that old, than how old is the process and material that made the star. So either calculations are inaccurate and need to be redone which may bring the age of the star within the current range of the Universe being 13.8 billion years old or the age of the Universe once again needs to be extended, or the star is out there beyond. Dubbed the 'Methuselah Star', it travels through the dark sky in the Milky Way for now. It is in an expansion stage and dwarfs Sirius, Rigel, Aldeberan and the Sun for example. Unique find or are there others like it in other galactic systems?

Further, an investigation there might also help determine whether there is anything more out beyond the scope of this universe.
