A physical body might be able to cross a wormhole, in spite of the extreme tidal forces, suggests a new study by Rubiera-Garcia, of Instituto de Astrofísica e Ciências do Espaço (IA), and his team. This result, published on April 28 in the journal Classical and Quantum Gravity, is supported by the fact that the interactions between the different parts of the body, which hold it together, are preserved. The team was invited by the journal editors to write an insight article.
In their previous work, the authors arrived at theoretical descriptions of black holes without a singularity, that bizarre and infinitesimally small point where space and time ends abruptly. What they found at the centre of a black hole, and without actually being in search of one, was a spherical and finite size wormhole structure. ...
Presented with this wormhole structure of finite size, where space and time continue past and beyond the black hole and into another part of the Universe, the authors then inquired about the fate of a physical object venturing into it. They asked if a chair, a scientist, or a spacecraft, would withstand the intense gravitational field and retain its unity as a body through the journey, and also to what extent would be the damage. ...
