The spacetime allows a geodesic curve (describing the movement of observers and photons in spacetime) to pass through the center of this ring singularity.

This kind of singularity has the following peculiar property. Since a point cannot support rotation or angular momentum in classical physics (general relativity being a classical theory), the minimal shape of the singularity that can support these properties is instead a ring with zero thickness but non-zero radius, and this is referred to as a ringularity or Kerr singularity. With a fluid rotating body, its distribution of mass is not spherical (it shows an equatorial bulge), and it has angular momentum. This is not the case with a rotating black hole (a Kerr black hole). When a spherical non-rotating body of a critical radius collapses under its own gravitation under general relativity, theory suggests it will collapse to a single point.

Python 3.11 is up to 10-60% faster than Python 3.10. The Faster CPython Project is already yielding some exciting results.gh-34627 - Atomic grouping ( (?>.)) and possessive quantifiers ( *+, ++, ?+, +) are now supported in regular expressions.

gh-90908 - Introduce task groups to asyncio.PEP 680 - tomllib: Support for Parsing TOML in the Standard Library.PEP 654 - Exception Groups and except*.PEP 657 - Include Fine-Grained Error Locations in Tracebacks.Some of the new major new features and changes in Python 3.11 are: General changes Major new features of the 3.11 series, compared to 3.10 Python 3.11.0 is the newest major release of the Python programming language, and it contains many new features and optimizations. This is the stable release of Python 3.11.0
