VESA Announces DisplayHDR True Black 600 Performance Tier

Alternatively, black holes can be classified by their two other properties of rotation and charge:

1. Schwarzschild Black Hole, otherwise known as a ‘static black hole’, does not rotate and has no electric charge. It is characterised solely by its mass.
2. Kerr Black Hole is a more realistic scenario. This is a rotating black hole with no electrical charge.
3. Charged Black Hole can be of two types. A charged, non-rotating black hole is known as a Reissner-Nordstrom black hole, a charged, rotating black hole is called a Kerr-Newman black hole.

Black holes have mass, angular momentum and potentially a charge.

Also, if QFT holds right for this part, there is no such thing as a 'true' vaccum. Even the so called 'Zero Vacuum Energy' could very well be, eh, not zero. I strongly recommend PBS series to beginners, that is, if you have the... spacetime.

Pedantry requires precision. a 'true' vacuum

Which spacetime @lexluthermiester might want in on this one?

A rotating black hole is a solution of Einstein's field equation. There are two known exact solutions, the Kerr metric and the Kerr–Newman metric, which are believed to be representative of all rotating black hole solutions, in the exterior region.

The Kerr–Newman metric is the most general asymptotically flat, stationary solution of the Einstein–Maxwell equations in general relativity that describes the spacetime geometry in the region surrounding an electrically charged, rotating mass. It generalizes the Kerr metric by taking into account the field energy of an electromagnetic field, in addition to describing rotation. It is one of a large number of various different electrovacuum solutions, that is, of solutions to the Einstein–Maxwell equations which account for the field energy of an electromagnetic field. Such solutions do not include any electric charges other than that associated with the gravitational field, and are thus termed vacuum solutions.
This solution has not been especially useful for describing astrophysical phenomena, because observed astronomical objects do not possess an appreciable net electric charge,[citation needed] and the magnetic field of stars arises through other processes. As a model of realistic black holes, it omits any description of infalling baryonic matter, light (null dusts) or dark matter, and thus provides at best an incomplete description of stellar mass black holes and active galactic nuclei. The solution is of theoretical and mathematical interest as it does provide a fairly simple cornerstone for further exploration.
The Kerr–Newman solution is a special case of more general exact solutions of the Einstein–Maxwell equations with non-zero cosmological constant.

BTW Polymath alert! Studied Science at UQ with my classmates (them Engineering) who are famous for the scramjet!

I strongly recommend PBS series to beginners ... I was across the concept of spacetime as a five-year-old!

I just realized we are thread-crapping. Please message me if you want to continue.
