This is, of course, only if the extreme gravity doesn’t destroy the observer first. For example, there is a point in the axis of symmetry that has the property that if an observer is below this point, the pull from the singularity will force the observer to pass through the middle of the ring singularity to the region with closed time-like curves and it will experience repulsive gravity that will push it back to the original region, but then it will experience the pull from the singularity again and will repeat this process forever. There are some other interesting free-fall trajectories. This interior solution is not likely to be physical and is considered a purely mathematical artefact. Since the trajectory of observers and particles in general relativity are described by time-like curves, it is possible for observers in this region to return to their past. The region beyond permits closed time-like curves. Available on Android, iOS, Mac and Windows. The spacetime allows a geodesic curve (describing the movement of observers and photons in spacetime) to pass through the center of this ring singularity.

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. PEP 655 - Marking individual TypedDict items as required or potentially-missingĪnd now for something completely different.PEP 675 - Arbitrary Literal String Type.On average, we measured a 1.22x speedup on the standard benchmark suite. Python 3.11 is up to 10-60% faster than Python 3.10. The Faster CPython Project is already yielding some exciting results. After installing Java, you may need to restart your browser in order to enable Java in your browser.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
