U1.27 is one of the large quasi-stellar radio source group in Leo. During a period [8] having a short it before having been a structure of the maximum space [1], but being updated to Hercules, the Corona Borealis great wall that [6], this record maintenance were discovered [4] [5] [2] [3] ten months later while I am known at the time of discovery.

Summary
Size
The length of U1.27 is both up to 4,040 million light-year, mean diameter and 1,630 million light-year [1]; [2] [4]. This is size to exceed far 1,380 million light-year in length of the Sloane great wall which is a maximum structure known by then [9]; [10]. The space which can observe of U1.27 at most of 23 times is only size [5]; [11]. Therefore, U1.27 is called alias Huge-LQG.
The galaxy becomes 325m in diameter when I reduce U1.27 to size (13,000km) of the earth, and the size of the earth is smaller than an atom.
Mass
U1.27 is one of 73 large quasi-stellar radio source group comprised of quasi-stellar radio source, and the placement of the quasi-stellar radio source lines up to quite describe the C-shape of the alphabet. It is thought that the mass of U1.27 is 6,100 quadrillion times (6.1 X 1018M☉) of the sun in total [2], and a galaxy belongs, and there is this more than 6 times of Pisces, Cetus supercluster Complex of 1 billion light-year in length comprised of approximately 60 galaxy clusters [12].
Distance
Seeing from the earth, U1.27 is at the 12,900 million light-year away position in the direction of Leo [1] and is the large quasi-stellar radio source group that existed in the times 8,700 million years ago. In other words, indicating being the large-scale structure that existed approximately 5 billion years after birth of the space [7].
Influence on cosmology
It is thought that the discovery of U1.27 gives a big problem in current astrophysics and space principle. That, by the current theory, bare になっているとされているが where a shock wave formed in the space after Big Bang makes large-scale structure of the current space, the size of the large-scale structure do not exceed approximately 1,200 million light-year [13]. The large-scale structure of the degree to exceed the theoretical values such as Sloane great walls a little was discovered so far, but U1.27 is a problem with this value much more at a point to exceed [1]; [4].
In addition, as for the existence of the large quasi-stellar radio source group such as U1.27, the space seems to be against space principle to be approximately uniform if I see it on an extremely big scale. A current mathematical description about the space is simplified excessively, and this may show an inappropriate thing to theorize large-scale structure of the real space. Possibly the space is more complicated, and a theoretical review may be required [3]; [5].
Furthermore, U1.27 may give some kind of answers about the formation of the supercluster to be able to put in the initial space. It is thought that the quasi-stellar radio source is in the form of very early days of the Milky Way which there is in the current space, and the large quasi-stellar radio source group that attracted them may be a pioneer figure of a galaxy cluster and the supercluster. However, I am mystery how huge structure such as U1.27 was formed in the young space which only passed from birth for 5 billion years. Therefore, it is thought that the mechanism that formed U1.27 may affect the evolution of the initial space in one way or another [3].
Quasi-stellar radio source to belong to
U1.27 was discovered by checking distribution of the quasi-stellar radio source registered with Sloane digital sky survey. Among 73 quasars belonging to U1.27, it is 13,616 million light-year (z=1.3713) of SDSS 105637.49+150047.5 that there is what there is to the nearest distance from the earth to 12,234 million light-year (z=1.1742) of SDSS 105140.40+203921.1, the most far-off distance. As for apparent magnitude being the brightest, it is a 19.080 class of SDSS 104321.62+143600.2 16.430 class of SDSS 105210.02+165543.7, that it is the darkest [2].
Other
It is 大 quasi-stellar radio source group same as U1.27, and, close to the apparent position of U1.27, U1.28 which is 2,050 million light-year in length exists. Because a value of the red shift is similar, the real distance is near approximately 100 million light-year, too. The number of the constitution quasi-stellar radio source is 34 [5].
