14 DAY TRIAL // In a paper published on the preprint science server arXiv, two European astrophysicists propose a new interpretation of black holes, which no longer holds that these structures are made up of an event horizon and a singularity. The duo argues in their new paper that black holes are in fact Planck stars.
The work was carried out by expert Carlo Rovelli, who holds appointments with the Center of Theoretical Physics at the Aix-Marseille University in Marseille, France, and with the Department of History and Philosophy of Science at the University of Pittsburgh, and Francesca Vidotto, who is based at the Institute for Mathematics, Astrophysics and Particle Physics (IMAPP) at the Radboud University.
The duo argues that it would make a lot more sense for the cores of black holes to contain Planck stars than a singularity, mostly because this would go a long way towards clearing up one of the most puzzling aspects of dark behemoths, which is how they return information they destroy back into the Universe.
This problem has been under investigation for many decades, but astrophysicists have failed to inch closer to a solution despite their efforts. A Planck star would solve this issue, since it would inflate inside the event horizon until the two eventually meet. The star would then be annihilated and all of the data it has ever consumed would return into the Cosmos, PhysOrg reports.
