> Right at the critical point, water looks weird. It look like a blur of droplets floating in gas. But if you look at any droplet you’ll see it’s full of bubbles of gas. And if you look in any of these bubbles you see it’s full of droplets. As you keep zooming in, you keep seeing basically the same thing…. droplets of liquid in gas, bubbles of gas in liquid…. until you get down to the scale of atoms. So we say this stuff has ‘conformal symmetry’. This is akin to a rather derided religious position: "it's turtles all the way down". The problem with all these claims is that one has to accept that we have established this in CERN or wherever. Have we? Can I check? Is it just the turtles story?
