Scientists have discovered a celestial structure made of galaxies more than 1.4 billion light-years long and 600 million light-years deep in the skies over the South Pole. The South Pole Wall is situated along the southern border of cosmos from the perspective of Earth, and consists of thousands of galaxies, hydrogen gas, dust, and dark matter. It's also one of the largest known structures in the universe. The wall is among a number of structures that make up the cosmic web, including the Great Wall, the Bootes Void, the comparably sized Sloan Great Wall and the Hercules Corona-Borealis Great Wall, the largest known structure at 10 billion light-years wide. That's about a tenth of the diameter of the observable universe. The South Pole Wall however, is half the distance from the Earth to the Hercules Corona-Borealis Great Wall-- 500 million light-years-- and was hidden by the brightness of the Milky Way in an area called the Zone of Avoidance. It was discovered when scientists saw galaxies in different directions around it were affected by its gravitational pull. The wall is the largest structure discovered with a 650 million light-year radius from Earth. The wall's bow-like makeup is the reason its length can fit the observed sphere. The map scientists used fades away just beyond the wall. So it just might be we are not seeing the whole of it, if it happens to bend away from us beyond our observational limit.
@Vette888,
This is not a humorous reply.
Obviously we as a species do not know how the time of the universe functions, we simply know it is not linear nor static in passing. This of course means that we as a species have no concept of distance and therefore scale which can be proven; We are only using our own measures which we know are not correct.
If you have ever watched the film series MiB then you are aware of the whole 'Train station locker' trope ..... If it doesn't make people wonder about our actual situation, then it should.
@Teufel,
we got the aliens to pay for the wall.
@Teufel,
You are correct - Size, Time, depth & perception are relative ONLY to its/their observer.
Have a Lovely Day
