A longstanding theory describing what happens to matter before it is consumed by a black hole is wrong, according to new experiments conducted at the planet’s most powerful X-ray scanner and detailed in research published earlier this month in the journal Physical Review Letters. Black holes are regions of spacetime that have gravitational fields so […]

No Comments »A Chinese satellite placed into orbit last summer has successfully used the laws of quantum mechanics to transmit information to Earth using an essentially unbreakable communications channel, according to BBC News and Los Angeles Times reports published Thursday. The experimental satellite known as Micius was launched from the Gobi desert in August 2016, and it […]
