[@Skallagrim] Hey old bones what exactly is [i]Cold light[/i]? Is it a solid? Gas? Plasma? What happens if you touch it or something touches it?

It is basically a quark-gluon plasma, it is very cold and very dense, basically a dense quark matter. I would not touch it and it is lock in a temporal warp torus that allows it to roam as it does in that tunnel.
