Three researchers from the Institute of Space Science (ISS) located on the Magurele Physics Platform propose a unique fingerprint to identify the disintegration of microscopic black holes – quantum black holes of very small dimensions, whose existence is still hypothetical. The identification of the signature they proposed based on observations can confirm the string theory and can change physics as we know it today. The contributions of the Romanian researchers have been published in the Journal of High Energy Physics, in Astroparticle Physics, and the third article is being published right now in an internationally renowned publication.
