Exploring the possibility of probing fundamental space-time symmetries via gravitational wave memory

by

Model selection between the original BMS symmetries (dashed lines) and the extended BMS symmetries (solid lines) with Einstein Telescope (ET) and Cosmic Explorer (CE). Evidence for the simulated symmetry group (log Bayes factor) is shown against observation time. Credit: Physical assessment letters (2024). DOI: 10.1103/PhysRevLett.132.241401 As predicted by general relativity, the passage of gravitational waves … Read more

Gravitational wave experts discover ‘remarkable’ secrets of ancient computers

by

Special techniques to study ripples in the universe may have helped researchers solve an age-old mystery. Statistical modeling methods developed to study gravitational waves have been used to predict the structure of a broken piece of a millennia-old artifact, according to a new paper in The Horological Journal. These techniques allowed researchers to determine how … Read more

University of Glasgow Techniques developed to analyze ripples in space-time detected by one of the most sensitive scientific instruments of the 21st century have shed new light on the function of the oldest known analog computer. Astronomers from the University of Glasgow have used statistical modelling techniques developed to analyse gravitational waves to determine the … Read more

MIT discovers surprising wave activity on Titan, Saturn’s largest moon

by
SciTechDaily

The surface of Titan. Simulations by MIT geologists indicate that the lakes and seas on Titan, Saturn’s largest moon, were formed by wave-induced erosion. Credit: NASA/JPL-Caltech Researchers find that wave activity on Saturn’s largest moon could be strong enough to erode the shorelines of lakes and seas. MIT researchers have used simulations to suggest that … Read more

Global election wave could hit UK financial system, Bank of England warns

by

The uncertainty caused by a global election wave starting in France this weekend threatens to destabilize the British financial system, the Bank of England has warned. Officials are concerned about the kind of policies newly elected governments can enforce in major economies, including the US, where Donald Trump is vying for another term as president … Read more

Heat wave advice: Which appliances you should switch off during a heat wave

by

As Britons prepare for a 30°C heatwave this week, a yellow heat warning has been issued in all but one region of England. The Met Office and the UK Health Security Agency have issued the warning from today (June 24) until Thursday afternoon due to the impact it could have on the health and social … Read more

Supercooled phase transitions: can they explain gravitational wave signals?

by

This article was reviewed according to Science fact checked peer-reviewed publication trusted source proofread OK! by Tejasri Gururaj, Phys.org To create nHz frequency signals, the vacuum junctions must be supercooled. These slow transitions are difficult to complete due to the cosmic expansion of the universe. Even when the transition is complete, the wave frequencies can … Read more

Supercooled phase transitions: can they explain gravitational wave signals?

by

To create nHz frequency signals, the vacuum junctions must be supercooled. These slow transitions are difficult to complete due to the cosmic expansion of the universe. Even when the transition is complete, the wave frequencies can shift away from nHz. Although nanohertz gravitational waves are cool, their origin is probably not supercooled.

The $200 billion wave of dealmaking in the U.S. shale industry is reshaping the energy landscape

by

Dealmaking in the U.S. oil and gas sector has soared to nearly $200 billion over the past year as the biggest producers battle to swallow up rivals in a race for scale that has reshaped the national energy landscape. But as the nation’s best drilling territory is captured, companies are casting a wider net, looking … Read more
