The 'liquid' nature of spacetime in quantum gravity models

Se lo spaziotempo fosse un liquido, avrebbe una viscosità bassissima, come i "superfluidi". Un lavoro che ha visto collaborare la Scuola Internazionale Superiore di Studi Avanzati (SISSA) di Trieste con l'Università Ludwig Maximilian di Monaco ha mostrato come dovrebbero comportarsi gli "atomi" che compongono il fluido dello spaziotempo, secondo alcuni modelli di gravità quantistica. Le…

Secrets of the Universe’s First Light

The  first definite proof that the Universe underwent an almost unimaginably fast expansion when it was only a trillionth of a trillionth of a trillionth of a second old has taken the world by storm. This sudden growth spurt was first theorized more than three decades ago. Yet only last month did astrophysicists reveal what may…

Discovered a close neighbor of the Sun

A “brown dwarf” star that appears to be the coldest of its kind — as frosty as Earth’s North Pole — has been discovered by a Penn State University astronomer using NASA’s Wide-field Infrared Survey Explorer (WISE) and Spitzer Space Telescopes. Images from the space telescopes also pinpointed the object’s distance at 7.2 light-years away,…
