I would argue they’re galactic, not cosmic strings — places that the quasar formed “loop” excitations which were somehow frozen in place when it extinguished.
Wow, I had no idea about anyons. What a fascinating concept.
This is probably a stupid question, but how can anything in our three dimensional world truly be two dimensional? How is that imposed on matter or energy?
I thought we used 1/2/3 dimensions to help ourselves understand our world better; like theoretical tools we can use on paper or a computer to simulate and explore reality. But we actually have 2 dimensional objects in the world?
