Large black holes are the most spherical things in the relative sense, not in an absolute sense; although more so than pico-black holes, which are not very spherical.
Light cones/the 4d-radii of causality are* perfectly spherical.
- kbelder 3y agoAren't they warped by the curvature of space/time that they are spreading over?
- doctor_phil 3y agoHow big a factor is the rotation of the black hole? Maybe look for a large black hole not rotating too much if you want to be sure. :-)
