Hello All:

I'm no astronomer, and know very little about string theory, but spotted the article linked below on a site called RedNova. I also don't know anything about the credibility of the website, but this sounds like it could be important stuff (cosmologically speaking).

Why does an article about two "nearly identical galaxies" have, as its only illustration, a photo of a section of the Veil Nebula in Cygnus?

Yeah that is kind of weird.

As far as the article goes, I'd be skeptical for now, but it is very interesting and should be worth keeping an eye on for awhile. I wonder how they could show conclusively that they are the same. Identical spectra maybe?

There is string therory then there are cosmological defects called cosmic super strings.

If you were to hit a cosmic string with an 'enlarge ray' set to inflate an atom to the size of the solar system--at that scale--the string is still thinner than a virus.

Literally as small as small can be.

But there are two and three-d cousins, called Domain Walls and Textures.

Do a search for the term 'cubic wormhole,' a cube with a wormhole on each of the cubes six faces.

You will find that interesting.
