Cosmic filaments may be the biggest spinning objects in space TL;DR Scientists have discovered that cosmic filaments, the largest known structures in the universe, are rotating. These massive, twisting filaments of dark matter and galaxies stretch across hundreds of millions of light-years and play a crucial role in channeling matter to galaxy clusters. The finding…
By mimicking a black hole’s event horizon, physicists observe Hawking radiation in an exciting lab experiment. TL;DR A group of physicists has simulated a black hole’s event horizon using a single-file chain of atoms, resulting in the detection of a thermal-like Hawking radiation. This experiment could help reconcile two major but conflicting scientific frameworks: general…
Analysis of a femur fossil indicates that a key species could already move somewhat like us TL;DR New research on a Sahelanthropus tchadensis fossil reveals that early humans were walking upright around seven million years ago, suggesting that bipedalism emerged far earlier than previously thought. Despite ape-like forearms used for tree-climbing, the femur analysis points…
Amazingly Sharp, Rectangular Iceberg Floats Near Antarctica’s Larsen C Shelf in NASA Image TL;DR NASA has captured an extraordinary image of a sharp-edged rectangular iceberg floating near the Larsen C ice shelf in Antarctica. While it appears unusual, this iceberg is a natural phenomenon known as a tabular iceberg, characterized by steep vertical sides and…
4 light years in 20 years. This beast be flying at a fifth of light speed. TL;DR Researchers are working on a new solar sail spacecraft, which could travel at 20% the speed of light and reach Alpha Centauri in just 20 years. The sail, using ultra-thin materials and lasers, can withstand intense forces and…
The closest black hole to Earth is a stellar-mass black hole named Gaia BH1, located just 1,600 light-years away. Gaia BH1 was discovered in 2022 using a combination of telescopes, including the Gaia spacecraft, the 6.5m Magellan Baade telescope at Las Campanas Observatory in Chile, and the Gemini Multi-Object Spectrograph on Gemini North. This black…
TL;DR Researchers propose that wormholes, theoretical space-time shortcuts, could allow faster-than-light communication via light pulses. While wormholes are known to collapse too quickly for anything to pass through, new calculations suggest that if the wormhole’s throat is much longer than its opening, it could naturally generate negative Casimir energy. This would slow the collapse enough…
Should be good as long as we don’t send out a map TL;DR Astronomers reveal that detecting Earth via photometric microlensing poses significant challenges for advanced alien civilizations. Despite Earth being a habitable planet, its location and proximity to the Sun make it nearly invisible to potential extraterrestrial observers. Microlensing, though effective at long distances,…
Scientists have long been puzzled over the origins of Martian meteorites found on Earth. TL;DR Scientists traced 200 meteorites from Mars to volcanic regions, Tharsis and Elysium, using high-resolution simulations. They pinpointed the craters responsible for launching these rocks into space, revealing the size and depth of the craters. The meteorites provide data about impact…
