Yes, it was basically the same as this one but ten feet higher.

"Giant Arc", with a creative name like that, I have imagine Alexia is a poet in her spare time. Was Big Arc already taken?

Like I'm going to listen about space stuff from someone who went to beauty school.

That action is pretty spooky at a distance.

Given the time it takes for one star to physically affect a star on the other side of its own galaxy, there is no reason to suspect that the components of that line ever, for the purpoes of physics, experience the superstructure as a line of galaxies. It's kind of interesting to see a fallacious, contemporaneouly anachronistic snapshot of objects from the perspective of Earth, projected onto the physics of distant objects that take hundreds of millions of years to see and affect each other. Come on, Physics Guys, stop thinking in 3 dimensions and forgetting about the 4th.

No, but the Golden Arcs belong to McDowell's

New scientist, so, largely not science at all, just feeding hysteria? Or have they gotten better since the last time I looked, it was still print back then.

They're not, that's the whole point.  They see that arc and it looks to them like it's organized, which is impossible because there hasn't been enough time.

Presumably these people have crunched the numbers and determined that the structure is 'real' (i.e., excluding the time factor most likely organized by force interaction rather than being a random accident) and that nothing from the Big Bang forward has had enough time to cause it.

Which means we don't understand something which is where we usually start to look for answers until we can explain it.

I'll figure it out before it gets here...

It's magic, obviously. Duh.
