Fermion stars as gravitational lenses
Neven Bilic, Hrvoje Nikolic, Raoul D. Viollier
We study in detail gravitational lensing caused by a supermassive fermion star and compare it with lensing by a black hole of the same mass. It is argued that lensing effects, bein…
Notes on covariant quantities in noninertial frames and invariance of radiation in classical and quantum field theory
H. Nikolic
A local observer can measure only the values of fields at the point of his own position. By exploring the coordinate transformation between two Fermi frames, it is shown that two o…
Relativistic contraction and related effects in noninertial frames
H. Nikolic
Although there is no relative motion among different points on a rotating disc, each point belongs to a different noninertial frame. This fact, not recognized in previous approache…
Some remarks on a nongeometrical interpretation of gravity and the flatness problem
H. Nikolic
In a nongeometrical interpretation of gravity, the metric is interpreted as an {\em effective} metric, whereas is interpreted as a fundamen…
The origin of the difference between space and time
Hrvoje Nikolic
All differences between the role of space and time in nature are explained by proposing the principles in which none of the spacetime coordinates has an {\it a priori} special role…
