Explaining gravity without string theory

For decades, most physicists have agreed that string theory is the missing link between Einstein’s theory of general relativity, describing the laws of nature at the largest scale, and quantum mechanics, describing them at the smallest scale. However, an international collaboration headed by Radboud physicists has now provided compelling evidence that string theory is not the only theory that could form…

Researchers find ‘missing link’ between magnetars and rotation-powered pulsars

Researchers from the RIKEN Cluster for Pioneering Research have made observations of a new magnetar, called Swift J1818.0-1607, which challenges current knowledge about two types of extreme stars, known as magnetars and pulsars. The research, just published in the Astrophysical Journal, was done using the Neutron star Interior Composition Explorer (NICER), an X-ray instrument aboard the International Space Station.

Observing the path less traveled boosts quantum gain

When probing the subtle effects of quantum mechanics, all the parameters in the system and its measurements need to be finely tuned to observe the result you are hoping for. So what happens when you gear everything towards detecting what you least expect? Researchers at MIT, Purdue University and IonQ in the U.S. took just this approach and found they could…

Astronomers discover ‘cosmic killer’ black hole

A type of black hole that could be an important ‘missing link’ has been discovered outside of our galaxy. Scientists have been hunting for evidence of… Source: https://www.unexplained-mysteries.com/news/335964/astronomers-discover-cosmic-killer-black-hole…

Researchers demonstrate the missing link for a quantum internet

A quantum internet could be used to send unhackable messages, improve the accuracy of GPS, and enable cloud-based quantum computing. For more than twenty years, dreams of creating such a quantum network have remained out of reach in large part because of the difficulty to send quantum signals across large distances without loss. …
