Additionally, astronomers speculated on neutron star land forms, paleontologists reported a previously unknown Cretaceous-era predator and a tech start-up is building a living seawall in Florida: Topology dense Massive supergiant stars collapse into neutron stars composed entirely of neutrons, supported against further gravitational collapse by neutron degeneracy pressure.
Astronomers have fun speculating on the weight of tiny amounts of neutron star material, like “one dishwasher soap receptacle full of neutron star material would weigh about 15 billion tons.”
Though the surface features of neutron stars are unknown, based on the formation of mountains on planets and moons, researchers have long theorized that neutron stars likely have mountains, or in the plain language of the ordinary working man, “nonaxisymmetric deformations.”
A new study by nuclear physicists at Indiana University considers possible features of neutron star mountains that could be analogous to terrain on Europa, Enceladus and other known solar system bodies.
The researchers propose that these types of features could be inferred by studying the continuous gravitational wave signals of neutron stars; the Laser Interferometer Gravitational Wave Observatory is now searching for the gravitational ripples created by neutron star mountains.
According to a report released this week by researchers at the Woods Hole Oceanographic Institute, the Atlantic Meridional Overturning Circulation, a crucial current, has not decreased in the past 60 years. A global group of geneticists discovered proof of women’s social and political empowerment during the Iron Age. A well-known thought experiment involving a cat was also shown by quantum engineers in a silicon chip. Moreover, paleontologists revealed a hitherto unidentified Cretaceous-era predator, astronomers conjectured about neutron star land forms, and a tech start-up in Florida is constructing a living coastline.
Dense topology.
Neutron degeneracy pressure prevents massive supergiant stars from collapsing further due to gravity, resulting in neutron stars made entirely of neutrons. They have a density of one trillion times that of lead, and once formed, they stop generating heat and eventually cool. It is amusing for astronomers to speculate about the weight of minuscule amounts of neutron star material. For example, they estimate that a single dishwasher soap container filled with neutron star material would weigh roughly 15 billion tons. “,”.
Researchers have long hypothesized that neutron stars probably have mountains, or “nonaxisymmetric deformations,” as the average working man would say, based on the formation of mountains on planets and moons, even though the surface features of neutron stars are unknown. Given their size, these mountains would emit waves of gravity.
A recent study by Indiana University nuclear physicists examines potential characteristics of neutron star mountains that might resemble the topography of Europa, Enceladus, and other known solar system bodies. The mountainous deformations seen on Mercury, for instance, may be universal since the planet has thin crustal sheets covering a sizable metallic core. According to the researchers, these kinds of features could be deduced by examining the neutron stars’ continuous gravitational wave signals; the Laser Interferometer Gravitational Wave Observatory is currently looking for the gravitational ripples that neutron star mountains produce.
They found a new guy.
In a stunning example of archival scholarship, a team of paleontologists used photos of Egyptian fossils that were destroyed during World War II to identify a previously unidentified species of Cretaceous predatory dinosaur. In 1914, they were taken from the Bahariya Oasis in Egypt and sent to Ernst Stromer von Reichenbach, a paleontologist in Munich. When an allied air raid hit the storage site, the fossils and other items were destroyed, and the discoveries were forgotten.
However, an LMU München master’s student recently discovered old photographs of the fossil that depicted the spine, skull, and hind limbs as they were displayed in an exhibition. After examining the image, paleontologists concluded that the remains belonged to an unidentified Cretaceous species. The dinosaur, known as Tameryraptor, had a noticeable nasal horn and measured 10 meters in length.
The corresponding paper’s first author, Maximilian Kellermann, states: “We were all taken aback by what we saw in the historical images. The fossilized Egyptian dinosaur that is portrayed there is very different from more recent discoveries of Carcharodontosaurus in Morocco. Thus, Stromer’s initial classification was inaccurate. Here, we discovered a whole new, undiscovered species of predatory dinosaur, which we have named Tameryraptor markgrafi. “,”.
Wall is clever.
As global sea levels rise and ice caps melt due to climate change, sea walls along coastlines are becoming increasingly important for climate resilience. In Florida, where beach erosion poses a threat to buildings and salt water has begun to seep into the ground, contractors are currently constructing the next generation of environmentally conscious sea walls, whose construction is just as sophisticated as its design. At a location close to Miami Beach, the company KindDesigns 3D prints portions of the wall using additive manufacturing equipment.
A prime example of bio-inspired design, the wall is constructed with raised sections modeled after mangrove roots, creating nooks and crannies that support marine life and lessen the force of waves and storm surges. Additionally, the developers claim that the cost of fabricating and constructing the wall is the same as that of traditional sea walls, so these advantages do not come at an increased cost.
