Real-life multiverse could exist and be ‘infinitely bigger’ than ever imagined, scientists discover

Posted by in categories: cosmology, quantum physics

A NEW study of quantum mechanics has argued that a real-life multiverse could be much bigger than ever previously imagined.

Just like the fictional multiverse depicted in sci-fi movies and the Marvel superhero universe, we too could be living in a world where multiple realities are possible.

That’s according to a study published on the academic site Arxiv.

‘Dark Stars’: Dark Matter may Form Exploding Stars, and Observing the Damage could help Reveal what it’s Made of

Posted by in category: cosmology

Dark matter is a ghostly substance that astronomers have failed to detect for decades, yet which we know has an enormous influence on normal matter in the universe, such as stars and galaxies. Through the massive gravitational pull it exerts on galaxies, it spins them up, gives them an extra push along their orbits, or even rips them apart.

Like a cosmic carnival mirror, it also bends the light from distant objects to create distorted or multiple images, a process which is called gravitational lensing.

And recent research suggests it may create even more drama than this, by producing stars that explode.

5,000 Tiny Robots Unveil Secrets Of Universe’s Dark Energy

Posted by in categories: cosmology, physics, robotics/AI

In a revolutionary scientific endeavor, researchers are using 5,000 miniature robots perched atop a mountaintop telescope to peer an astonishing 11 billion years into the past. This cutting-edge instrument, known as the Dark Energy Spectroscopic Instrument (DESI), is capturing light from distant objects in space, allowing scientists from the Lawrence Berkeley National Laboratory to map our cosmos as it was in its infancy and trace its evolution to the present day.

Why is this so important? Understanding how our universe has evolved is intrinsically linked to predicting its ultimate fate and unraveling one of the biggest mysteries in physics: dark energy. This enigmatic force is causing our universe to expand at an ever-increasing rate, and DESI is providing us with unprecedented insights into its effects over the past 11 billion years.

Black Hole Effects on Quantum Information Discovered in Everyday Chemistry

Posted by in categories: chemistry, cosmology, mathematics, particle physics, quantum physics

Nothing makes a mess of quantum physics quite like those space-warping, matter-gulping abominations known as black holes. If you want to turn Schrodinger’s eggs into an information omelet, just find an event horizon and let ‘em drop.

According to theoretical physicists and chemists from Rice University and the University of Illinois Urbana-Champaign in the US, basic chemistry is capable of scrambling quantum information almost as effectively.

The team used a mathematical tool developed more than half a century ago to bridge a gap between known semiclassical physics and quantum effects in superconductivity. They found the delicate quantum states of reacting particles become scrambled with surprising speed and efficiency that comes close to matching the might of a black hole.

New highly-detailed 3D map of universe with 6 million galaxies can unravel mysteries of dark matter

Posted by in categories: cosmology, futurism

A highly detailed three-dimensional map of six million galaxies was recently unveiled by a group of scientists. The map is believed to have the potential to unravel some hidden secrets of dark matter and the future of our universe.

The map was created with the help of data collected by the Dark Energy Spectroscopic Instrument (DESI) in Arizona. The first-of-its-kind map has scaled some galaxies for the first time that were never recorded earlier for the study of the universe.

DESI is an instrument that can capture light from 5,000 galaxies many million light years away from Earth. It becomes the backbone of research in the development of the biggest 3D map of galaxies that could alter the way we think about dark matter and the universe.

Dark Energy Could Be Evolving Over Time, Raising Questions About the Nature of the Cosmos

Posted by in categories: cosmology, robotics/AI

The new research culminated in a 3D map that measures how the universe has been expanding over the past 11 billion years. The data was collected by the Dark Energy Spectroscopic Instrument (DESI), a part of the Nicholas U. Mayall Telescope at the Kitt Peak National Observatory in Arizona.

Five thousand tiny robots on the telescope collect data at an unprecedented rate, per a statement from the observatory. Since it started scanning the sky in 2021, DESI has observed 5,000 galaxies every 20 minutes, totaling more than 100,000 galaxies each night.

Persistent “hiccups” in a far-off galaxy draw astronomers to new black hole behavior

Exploring the Black Hole Population with an Open Mind

Posted by in categories: cosmology, physics

A new model describes the population of black hole binaries without assumptions on the shape of their distribution—a capability that could boost the discovery potential of gravitational-wave observations.

Since the first groundbreaking observation of gravitational waves from a black hole merger [1], a worldwide network of observatories–LIGO, Virgo, and KAGRA—has discovered nearly a hundred mergers involving black holes and neutron stars (Fig. 1). The nature of this population of compact objects has implications for nearly every aspect of astrophysics and cosmology. However, understanding how gravitational-wave sources fit into our astrophysical theories has proved challenging. Many of the discoveries have confirmed our expectations, but some—such as those of asymmetric black hole binaries or of unexpectedly massive black holes—defy them.

FASER measures high-energy neutrino interaction strength

Posted by in categories: cosmology, particle physics

Operating at CERN’s Large Hadron Collider (LHC) since 2022, the FASER experiment is designed to search for extremely weakly interacting particles. Such particles are predicted by many theories beyond the Standard Model that are attempting to solve outstanding problems in physics such as the nature of dark matter and the matter-antimatter imbalance in the universe.

Unveiling the Invisible: How BREAD Is Redefining Dark Matter Searches

Posted by in categories: cosmology, particle physics

BREAD’s innovative approach to dark matter detection uses a coaxial “dish” antenna to scan for mysterious particles.

One of the great mysteries of modern science is dark matter. We know dark matter exists thanks to its effects on other objects in the cosmos, but we have never been able to directly see it. And it’s no minor thing—currently, scientists think it makes up about 85% of all the mass in the universe.

A new experiment by a collaboration led by the University of Chicago and Fermi National Accelerator Laboratory, known as the Broadband Reflector Experiment for Axion Detection or BREAD, has released its first results in the search for dark matter in a study published in Physical Review Letters. Though they did not find dark matter, they narrowed the constraints for where it might be and demonstrated a unique approach that may speed up the search for the mysterious substance, at relatively little space and cost.
