Heat waves could increase significantly by mid-century, according to a new study

Credit: CC0 Public Domain Our planet baked under the sun this summer as temperatures reached the hottest ever measured and heat waves spread across the globe. As the climate continues to warm, scientists expect an increase in the frequency and intensity of heat waves. A frequently overlooked aspect, however, is the spatial size of the heatwaves, despite their important implications. …

Underground detector in Japan to search for gravitational waves

Illustration of the underground KAGRA detector. Illustration : ICRR, Univ. from Tokyo. A fourth gravitational wave detector, this one in Gifu Prefecture Japan, will join this December's global search for cosmic events causing waves in space-time. The Kamioka gravitational wave detector -Wave Detector (KAGRA) is in the commissioning phase according to a press release and will link the two LIGO …

The "ringing" of the black hole emitting gravitational waves supports Einstein's Theory of Relativity

The "ringing" of the black hole, which emitted weak gravitational wave tones after the merger, supports Einstein's theory of relativity even more. Researchers have discovered sounds that emanate from a black hole. The discovery confirms a theory by Albert Einstein from 100 years ago The merging of black holes emits gravitational waves that reverberate at certain sounds. The waves could …

3 tropical waves and a tropical storm

The National Hurricane Center oversees several areas that say they have little chance of development in the coming days, and one could be a rainmaker for Florida. The area closest to Florida is an area of ​​unorganized rainfall and thunderstorms that is currently near the north coast of Hispaniola. It has a 20 percent chance of developing over the next …

The rock that vibrates to the beat of earth, wind and waves

University of Utah scientists have conducted the first detailed seismic measurements of a columnar sandstone formation in Moab National Park, known as the Castleton Tower. The structure vibrates at two key resonant frequencies, according to a new article in the Bulletin of the Seismological Society of America (19459003). That is, it is likely to withstand low to moderate magnitude earthquakes. …

The breakthrough enables storage and release of mechanical waves without loss of energy

Experimental set-up consisting of waveguide strip with cavity and side channels. The excitation of the elastic waves propagating along the rod is by piezoelectric actuators at the two ends of the system. Picture credits: Giuseppe Trainiti, Georgia Tech Light and sound waves provide the basis for energy and signal transport, and are fundamental to some of our most basic technologies, …

Scientists discovered waves from a black hole that swallowed a neutron star

Nearly a billion years ago, a black hole seems to have eaten a dead star – "like Pac-Man," said Susan Scott, a physicist at the Australian National University. Scott's team believes that the waves in the spacetime of this event, also known as gravitational waves, have just reached Earth. Such disturbances were first theorized by Albert Einstein, who in 1915 …
