IN A NUTSHELL 🚀 A DARPA-led team set a new record by transmitting 800 watts over 5.3 miles using optical power beaming. ⚡ Power beaming could revolutionize energy delivery to remote locations and reduce logistical challenges. 🔬 The breakthrough involved a customized receiver and a high-energy optical laser to maximize efficiency. 🌍 Future phases aim
Using NASA’s Chandra and ESA’s XMM-Newton space observatories, Indian astronomers have explored the population of ultraluminous X-ray sources in the galaxy NGC 5813, which resulted in the detection of a new source of this type. Results of the observational campaign were published August 7 on the pre-print server arXiv.
Researchers Robert Hazen and Michael Wong have put forward a bold new law of nature — one that could explain how everything in the universe evolves, from atoms, minerals and stars to living cells, ecosystems and even human civilization. At the heart of their theory is the idea that information is as fundamental to the cosmos as mass, energy or charge. Their law revolves around a concept called functional information — a measure of the ratcheting-up of complexity and function in evolving systems over time.
Just as ocean waves shape our shores, ripples in space-time may have once set the Universe on an evolutionary path that led to the cosmos as we see it today.
A new theory suggests gravitational waves – rather than hypothetical particles called inflatons – drove the Universe’s early expansion, and the redistribution of matter therein.
“For decades, we have tried to understand the early moments of the Universe using models based on elements we have never observed,” explains the first author of the paper, theoretical astrophysicist Raúl Jiménez of the University of Barcelona.
