Can the energy of a particle be negative in the absence of external fields?
A. A. Grib, Yu. V. Pavlov
We study the question of conditions for the existence of negative-energy states of particles in the absence of external fields in inertial and noninertial frames of reference. We s…
Particles of negative and zero energy in black holes and cosmological models
A. A. Grib, Yu. V. Pavlov
Particles with negative energies are considered for three different cases: inside of horizon of Schwarzschild black hole, Milne's coordinates in flat Minkowski space-time (Milne's…
Some effects of different coordinate systems in cosmology
A. A. Grib, Yu. V. Pavlov
The analysis of the dynamics of radial movement in different reference frames used in cosmology is made. Use of different frames leads to the difference in inertial forces resultin…
Regular frames and particle's rotation near a black hole
Yu. V. Pavlov, O. B. Zaslavskii
We consider a particle moving towards a rotating black hole. We are interested in the number of its revolution around a black hole. In our previous work (Pavlov and Zaslavskii…
Number of revolutions of a particle around a black hole: Is it infinite or finite?
Yu. V. Pavlov, O. B. Zaslavskii
We consider a particle falling into a rotating black hole. Such a particle makes an infinite number of revolutions from the viewpoint of a remote observer who uses the Boyer-Li…
Comparison of particle properties in Kerr metric and in rotating coordinates
A. A. Grib, Yu. V. Pavlov
Properties of particles in Kerr metric are compared with properties of particles in rotating coordinates in Minkowski space-time. It is shown that particles with negative and zero…
On the possibility of observation of the future for movement in the field of black holes of different types
Yu. V. Pavlov
It is shown for a spherically symmetric black hole of general type that it is impossible to observe the infinite future of the Universe external to the hole during the finite prope…
On particle collisions near Kerr's black holes
A. A. Grib, Yu. V. Pavlov
Scattering of particles in the gravitational field of rotating black holes is considered. Expressions for scattering energy of particles in the centre of mass system are obtained.…
Is it possible to see the infinite future of the Universe when falling into a black hole?
A. A. Grib, Yu. V. Pavlov
A possibility to see the infinite future of the Universe by an astronaut falling into a black hole is discussed and ruled out.
