It was nice to hear about some of the things keeping astrophysicists busy,
like being able to restart _only_ that part of a simulation that failed and all of its dependent parts.

Apparently, when astrophysicists are not busy playing guitar (but no synthesizers!).

Also nice to hear Ken Olum talk about (hyper)cubes on the 3³-th day of the 2³-th month.

An impossibly huge ring of galaxies might lead us to new physics. Here's how

The ring of galaxies, appropriately called the "Big Ring," has a circumference of nearly 4 billion light-years.

The discovery of the Big Ring makes it to the frontpage of the Financial Times!

"This Big Ring of galaxies and galaxy clusters joins an expanding catalogue of mammoth structures that defy scientific expectation."

A new galactic superstructure could undo science’s theory of the universe

The finding has provoked a mixed reaction among the cosmological cognoscenti

A 1.3bn light year-sized ring discovered by PhD student in Lancashire appears to defy the cosmological principle assumption

The Guardian
Have we found filaments of pure energy unleashed during the big bang?

Puzzling ancient galaxies and oddly shaped clusters suggest we have glimpsed cosmic strings travelling at the speed of light – and with them clues to a deeper theory of reality

Michio Kaku: “The mind of God, we believe, is cosmic music. The music of strings resonating through 11-dimensional hyperspace.”
