☆ A 'cosmic glitch' in the universe is forcing astronomers to rethink Einstein's theory of relativity
▼ + stars: | 2024-05-20 | by ( Ellyn Lapointe | ) www.businessinsider.com time to read: +8 min

Einstein's general theory of relativity states that the curvature of space-time causes gravity. But zoom out to enormous scales like clusters of galaxies spanning billions of light years across, and the laws of Einstein's gravity theory appear to change. A 1% adjustment may not sound like a big deal, but it's enough to suggest that Einstein's theory may need a rethink. Now, with this cosmic glitch, there's a new explanation on the table. NASA/CXC/Univ of Missouri/M.Brodwin et al; NASA/STScI; JPL/CalTechThe fact that this cosmic glitch could potentially help astronomers resolve the Hubble tension is a good sign that it may truly exist.

☆ Extreme weather blunts the US military's technological edge
▼ + stars: | 2024-05-19 | by ( Michael Peck | ) www.businessinsider.com time to read: +6 min

Read previewMore extreme weather is scrambling the high-tech systems that have given the US military its edge. For example, severe weather can degrade navigation systems such as GPS and sensors on precision-guided munitions. Heavy rain ground aircraft and drones, intense heat exhausts troops, dust storms gum up tank engines, and storms damage ships at sea. The problem is that tactical units on the front lines, or in remote areas, often lack the connectivity to receive weather reports. "NOAA [the National Oceanic and Atmospheric Administration], the private sector and universities are actively working to improve global weather models," Regens said.

Analysts say the US is gaining invaluable insights into the flaws of some of its most important weapons and military production systems. AdvertisementA shortage in weaponsThe Ukraine war has exposed problems not just with the quality of weapons, but with the US' capacity to produce them in the quantity Ukraine needs. "The biggest problem that the Ukraine war has exposed with American weapons is that the Pentagon simply does not buy enough munitions for a large-scale protracted conflict," said Pettyjohn. AdvertisementShe added that the recent Ukraine aid bill, which also contains billions for US weapons production, doesn't fix the problem. But though the war has posed serious conundrums for Pentagon chiefs, it's also shown that many of its weapons systems remain much better than those of its opponents.

Here, the NanoRacks-Remove Debris satellite is deployed from the International Space Station in 2018. Before revelations about Russia’s development of a nuclear anti-satellite weapon, there had been indications of global recognition that the use of certain space weapons was bad for everyone. The proposed defense budget for 2025 does not reflect the scale and urgency of the need to counter space threats and protect space systems. Learning how to operate satellites in a space environment clogged with debris or increased radiation caused by a space weapon is also important. We need a two-pronged effort to prepare for the worst: Double down on efforts to protect and maintain access to space in a hostile space environment and consider how to operate without space.

The last story in her last book evoked her mother’s death. Does it seem reductive or limiting to derive a kind of artist’s statement from the title of that early book? Munro was hardly a doctrinaire feminist, but with implacable authority and command she demonstrated throughout her career that the lives of girls and women were as rich, as tumultuous, as dramatic and as important as the lives of men and boys. For a writer whose book titles gestured repeatedly at love (“The Progress of Love,” “The Love of a Good Woman,” “Hateship, Friendship, Courtship, Loveship, Marriage”), her narratives recoiled from sentimentality. You got the feeling that, if the GPS ever offered her a shorter route, she would decline.

☆ The Solar Storm Fried GPS Systems Used by Some Farmers, Stalling Planting
▼ + stars: | 2024-05-13 | by ( Livia Albeck-Ripka | ) www.nytimes.com time to read: +1 min

The powerful geomagnetic storm that cast the northern lights’ vivid colors across the Northern Hemisphere over the weekend also caused some navigational systems in tractors and other farming equipment to break down at the height of planting season, suppliers and farmers said. Many farmers have come to rely on the equipment, which uses GPS and other navigational technology and helps them to plant more efficiently and precisely by keeping rows straight and avoiding gaps or overlap. In Minnesota, some farmers who had planned to spend Friday night sowing seeds were hamstrung by the outages. “I’ve never dealt with anything like this,” said Patrick O’Connor, the owner of a farm about 80 miles south of Minneapolis that mainly grows corn and soybean. Mr. O'Connor said that after being rained out for two weeks, he got into his tractor around 5 p.m., hoping to spend the night planting corn.

In a future war, electronic warfare and anti-satellite weapons could leave the US military without GPS, a critical tool for navigation and targeting. That challenge has prompted the US Air Force to experiment with using artificial intelligence as an alternative navigation method.

☆ Solar storms could create rare aurora displays, impact communications on Earth this weekend
▼ + stars: | 2024-05-10 | by ( Ashley Strickland | ) edition.cnn.com time to read: +6 min

When the energized particles from coronal mass ejections reach Earth’s magnetic field, they interact with gases in the atmosphere to create different colored light in the sky. The Space Weather Prediction Center tracked multiple strong flares emitting from a large cluster of sunspots on the solar surface since Wednesday. Alex Kormann/Star Tribune/Getty ImagesThe effects of geomagnetic stormsWhen directed at Earth, these ejections can cause geomagnetic storms, or major disturbances of Earth’s magnetic field. So far, researchers have obseverd only three severe geomagnetic storms during the current solar cycle, which began in December 2019, according to the center. The storms also affect flight patterns of commercial airlines, which are instructed to stay away from Earth’s poles during geomagnetic storms due to loss of communication or navigation capabilities.

NOAA has forecasted a "severe" geomagnetic storm to hit Earth this Friday, triggering aurora borealis. This storm comes as we approach solar maximum: the peak of solar activity during the sun's 11-year cycle. As a result, the National Oceanic and Atmospheric Administration issued a rare forecast for a "severe" G4 geomagnetic storm to hit Earth this Friday. NASADuring solar maximum, the sun develops more and larger sunspots, like the ones in region 3664, compared to quieter periods of solar activity. Severe geomagnetic storms like the one forecasted to hit this Friday are rare.

G4 storms are the second-strongest type of geomagnetic storm. "If geomagnetic storms were hurricanes, 'severe' would be category 4," according to SpaceWeather.com. Solar storms happen when the sun shoots powerful explosions of highly-energized and magnetic plasma called coronal mass ejections toward Earth. Also, a severe storm might disrupt GPS, so it's best to have a written record and directions to important locations, like hospitals.

☆ Why tonight’s massive solar storm could disrupt communications and GPS systems
▼ + stars: | 2024-05-10 | by ( Brian Fung | ) edition.cnn.com time to read: +5 min

NOAA’s severe space weather watch suggests the storm could trigger numerous effects for life on Earth, possibly affecting the power grid as well as satellite and high frequency radio communications. Moreover, the changes to the ionosphere can block or degrade radio transmissions trying to pass through the atmosphere to reach satellites. And they can also prevent radio transmissions from successfully bouncing off the ionosphere — which some radio operators normally do to increase the range of their signals. The Cybersecurity and Infrastructure Security Agency outlined a similar report in a 2021 presentation on space weather, finding that line-of-sight radio transmissions are generally not affected by space weather except in specific situations. The largest known geomagnetic storm in history, known as the Carrington Event of 1859, caused telegraph stations to spark and catch fire.
