5 Is the Schwarzschild black hole really stable ? ∗
The stability of the Schwarzschild black hole is studied. Regge and Wheeler treated the problem first at 1957 and obtained the dynamical equations for the small perturbation. There are two kinds of perturbations: odd one and even one. Using the Painlevé coordinate, we reconsider the odd perturbation and find that: (1)the black-hole-connected universe (r > 2m, see text) is more stable than that ...

There are two kinds of perturbations: odd one and even one. Using the Painlevé coordinate, we reconsider the odd perturbation and find that: the white-hole-connected universe (r > 2m, see text) is unstable. Because the odd...
متن کاملA Supermassive Black Hole in the S0 Galaxy Ngc 3245
The S0 galaxy NGC 3245 contains a circumnuclear disk of ionized gas and dust with a radius of 1. 1 (or 110 pc), making it an ideal target for dynamical studies with the Hubble Space Telescope (HST ). We have obtained spectra of the nuclear disk with the Space Telescope Imaging Spectrograph, using an 0. 2-wide slit at five parallel positions. Measurements of the Hα and [N II] emission lines are ...
متن کاملSpectroscopic Evidence for a Supermassive Black Hole in Ngc 4486b
The stellar kinematics of the low-luminosity elliptical galaxy NGC 4486B have been measured in seeing σ∗ = 0. 22 with the Canada-France-Hawaii Telescope (CFHT) and Subarcsecond Imaging Spectrograph. Lauer and collaborators have shown that NGC 4486B is similar to M31 in having a double nucleus. Here we show that it also resembles M31 in its kinematics. Like M31, NGC 4486B rotates fairly rapidly ...
متن کاملUniverse Is the Black Hole
Physico-mathematical parallels between the Expansive Nondecelerative Universe model and black holes justify us to be convicted that each universe can be considered as a black hole. This is why there must exist a fractal arrangement of the Multiuniverse that is boundless both in time and space.
