[Continuation] Why James Webb Telescope rewrites/doesn't the laws of Physics/Redshifts (2)

For my 5000th post, I'm going to tell a joke about differential geometry.

(Stop me if you've heard this one before.)

An engineer, physicist, and mathematician were visiting a farmer friend in Wales. The farmer enlisted their help in designing a fence that would surround his sheep using as little fencing as possible.
The engineer drew some rectangles on graph paper, did some calculations, and said a square fence would be best.

The physicist said no, the fence should be circular, like the sheep.

The mathematician said it doesn't matter whether it's a square or a circle. Either way, there is no lower bound to the perimeter. To demonstrate, she used a stick to draw a circle in the ground, then drew a square inside the circle, then a circle inside the square. "These circles and squares represent the perimeter of a fence that surrounds the sheep. By induction, the perimeter can be made arbitrarily small. I am of course assuming you don't need to stand outside the fence."
