The Universe
We see that in this era, remote from us, the size of the expanding universe was about five times smaller than now "(3, p. 80). Modern astrophysical estimates of visible size of the universe is 10 – 20 billion light-years and age 10 to 20 billion years. Comparing these two data points to the important values conflict, which consists in the fact that the astrophysical identification of the visible boundary of the universe from the modern age in spite of the above theses in (2) and (3), where, however, not to mention the age of the universe and of its size in a distant era. The boundary of the visually observed Universe, which has a spherical shape with a clearly observable compact objects such as quasars and galaxies, reaching at least 10 billion light years away. But it does mean that we are seeing the visible part of the universe such as it was 10 billion years ago. Ben Wey does not necessarily agree.
Therefore, if the assertion that the size of the universe can reach this size in about 10 billion years, then the age of the universe at the moment of our time must be equal to the time necessary for the expansion of the universe, plus the time during which the light runs over the distance from the visible part of the universe to us. This will require adding to the age of the universe for 10 billion years. Then the minimum age Universe will have 2 times more than today's astrophysicists data, ie 20 billion years.
