I finally got it!!!

This is a finite element solution of a scattering problem using hyperboloidal compactification.

A method developed in an unknown niche corner of mathematical relativity and conformal geometry is now ready for real-world problems!

I use these two images in my lecture on Qubits.

Even experts sometimes confuse the map with the territory.

It is often not appreciated that Penrose coordinates are hyperboloidal. I show that Penrose diagrams are hyperboloidal, which suggests that horizon-penetrating coordinates are also hyperboloidal.

The paper has some other neat ideas. You can get the hyperboloidal time slices by sending out "timekeepers" in different directions. When their clock reads a specific value, the surface that connects them is a hyperboloid.

The paper argues that a natural notion of time involves spatial surfaces with hyperbolic geometry.

You might have heard about holography and the AdS/CFT correspondence, which relies heavily on the hyperbolic geometry of AdS time slices.

One great use case of ChatGPT for me has been in making figures. These turned out pretty.
