Stephen Hawking’s 50-year-old theorem on how black holes merge together has been successfully tested thanks to huge advances in gravitational wave astronomy, which helped astronomers catch the waves ...

Back in 1971, the late physicist Stephen Hawking made an intriguing prediction: The total surface area of a black hole cannot decrease, only increase or remain stable. So if two black holes combine, ...

A roundup of flat, knee-high styles that are both practical and pleasing to the eye. By Jaclyn Bloomfield In T’s column 1 Piece, 10 Budgets, we share 10 perfect versions of an item in a range of ...

An eon ago, when only microbes dwelled on Earth, a pair of black holes some 1.3 billion light-years beyond the solar system spiraled toward each other until they crashed. The two became one big black ...

Discovery joins a list of the greatest hits of the LIGO detector, which ten years ago became the first to detect gravitational waves. The songs of the cosmos, now that we can finally hear them, might ...

Abstract: In our previous work, we design a trapezoid virtual tube to guide robotic swarms through narrow openings. This article extends the application of the trapezoid virtual tube to the situations ...

Abstract: This article develops a small-gain technique for the safety analysis and verification of interconnected systems with high-relative-degree safety constraints. To this end, a ...

Stroke is often attributable to cardiothoracic factors, but the need for ECG gating and limited spatial resolution on conventional computed tomography often limits the detection of pathology relevant ...
