A Giant Structure in Space Challenges Our Understanding of The Universe

A Giant Structure in Space Challenges Our Understanding of The Universe

A colossal structure in the distant Universe is defying our understanding of how the Universe evolved.

In light that has traveled for 6.9 billion years to reach us, astronomers have found a giant, almost perfect ring of galaxies, some 1.3 billion light-years in diameter. It doesn't match any known structure or formation mechanism.

The Big Ring, as the structure has been named, could mean that we need to amend the standard model of cosmology.

The discovery, led by astronomer Alexia Lopez of the University of Central Lancashire, was presented at the 243rd meeting of the American Astronomical Society in January, and has been published in the Journal of Cosmology and Astroparticle Physics.

1. I haven't read the article (will), but doesn't the shape of the ring and arc depend on your viewing perspective?

Give the trillions (more?) of visible objects in the universe it seems that we can choose some groups that have interesting characteristics. Just like animals in the clouds and men on the moon.

Thanks. Now diving in.....

3. Seems like a reasonable hypothesis. I'd hope the real scientists have already looked at this.

Of course for these images to be gravitationally-lensed over the huge time-frame and distance might imply there is some interesting object in between causing the lensing.

Oh, science. Keep me away from the political shitstorm.
