As the universe decompresses so will the relation of matter, energy and time change. Although it is the same balloon, in the different conditions it fails to be a valid reference. When tymitons are compressed, the interaction with matter, makes time slower. We see such phenomena at the edge of a black hole. It is difficult to estimate the age of the universe in earth years, because earth years are not equivalent in the time relations of the early universe.
Further difficulties arise in trying to study the early universe.
In trying to see back to the origins of the universe, we need to understand that time is the luminiferous ether, the media through which light travels. In the early universe, tyme was so compressed that light could not penetrate it. The same phenomena occurs even now, at the edge of black holes, where tyme is so compressed that light can not penetrate it. What this means is that when we try to see back to the origins of the universe we will only be able to see back to the point that the universe had decompressed enough for light to travel through tymitons. As the Universe continues to decompress, the balance between matter and time will continue to change.
