[hep-th] Seminar grupe za gravitaciju, cestice i polja, 4. jun 2021.

[Marija Dimitrijevic Ciric]

Zdravo svima,

evo najave seminara koji ce Dejan Stojkovic (University at Buffalo-The 
State University of New York) drzati u petak 4. juna.


Title: In search of a wormhole

Abstract: If a traversable wormhole smoothly connects two different 
spacetimes, then the flux cannot be separately conserved in any of these 
spaces individually. Then objects propagating in a vicinity of a 
wormhole in one space must feel influence of objects propagating in the 
other space. We show this in the cases of the scalar, electromagnetic, 
and gravitational field. The case of gravity is perhaps the most 
interesting. Namely, by studying the orbits of stars around the black 
hole at the center of our galaxy, we could soon tell if this black hole 
harbors a traversable wormhole. Alternatively, one can expect the same 
effect in black hole binary systems, or a black hole - star binary 
systems, which are actually the cleanest and most sensitive systems for 
such a search.
