Most massive stellar black hole in the Milky Way discovered ‘extremely close’ to Earth
Posted by Dan Breeden in categories: cosmology, physics
I found this on NewsBreak: Most massive stellar black hole in the Milky Way discovered ‘extremely close’ to Earth.
Astronomers have found the most massive stellar-mass black hole ever discovered in our galaxy — and it’s lurking “extremely close” to Earth, according to new research.
The black hole, named Gaia BH3, is 33 times more massive than our sun. Cygnus X-1, the next-biggest stellar black hole known in our galaxy, weighs only 21 solar masses. The newfound black hole is located roughly 2,000 light-years away in the constellation Aquila, making it the second-closest known black hole to Earth.

Scientists make breakthrough with advanced technology generating water from thin air — and it could save millions of lives
Posted by Dan Breeden in categories: energy, physics, sustainability
I found this on NewsBreak.
Researchers in China have reportedly developed a new technology similar to hydropanels for harvesting water out of thin air that is powered by energy from the sun. The device could be especially useful in dry, arid areas where water — but not sunlight — is hard to come by.

Hyperjumps, wormholes, and warp drives sound like science fiction, but they’re actually based on real science! Though I believe out of the three, warp drives are the most plausible. The math seems to agree. Today I want to tell you about a new way of analysing and visualizing warp drives.

Physicists solve puzzle about ancient galaxy found by Webb telescope
Posted by Dan Breeden in categories: physics, space
Last September, the James Webb Space Telescope, or JWST, discovered JWST-ER1g, a massive ancient galaxy that formed when the universe was just a quarter of its current age. Surprisingly, an Einstein ring is associated with this galaxy. That’s because JWST-ER1g acts as a lens and bends light from a distant source, which then appears as a ring—a phenomenon called strong gravitational lensing, predicted in Einstein’s theory of general relativity.

Video: Largest 3D map of the universe reveals hints of new physics
Posted by Paul Battista in categories: physics, space, virtual reality
Astronomers have produced the largest 3D map of the universe, which can be explored in an interactive VR video. In the process, they’ve uncovered some tantalizing hints that our understanding of physics, including the ultimate fate of the cosmos, could be wrong.
The Dark Energy Spectroscopic Instrument (DESI) is a huge international project to map out the universe in three dimensions, which began collecting data in 2021. This early version of the map only includes data collected during the first year – 5.7 million galaxies and quasars out of the planned goal of 40 million. This data allows the scientists to peer as far as 11 billion light-years into deep space and time, providing a glimpse into the very early universe with an unprecedented precision of less than 1%.

Lee Smolin — Are the Laws of Nature Always Constant?
Posted by Dan Breeden in categories: habitats, physics, space
The laws of nature or physics are assumed to be everywhere the same, on the far side of the universe as sure as on the far side of your house. Otherwise science itself could not succeed. But are these laws equally constant across time? Might the deep laws of physics change over eons of time? The implications would be profound.

Fast radio bursts: Research introduces a novel approach to characterize their behavior
Posted by Saúl Morales Rodriguéz in categories: physics, space
Fast radio bursts (FRBs) represent the most intense radio explosions in the universe. Since the first discovery in 2007, FRBs have garnered significant attention, culminating in the 2023 Shaw Prize in Astronomy. With yet unknown origin, these extreme cosmic bursts are among the most enigmatic phenomena in astronomy as well as physics.
