Scientists may have finally ‘seen’ dark matter for the 1st time

And this isn’t the only close match. The energy signature of these gamma-rays closely matches those predicted to emerge from the annihilation of colliding WIMPs, which are predicted to have a mass around 500 times that of a proton, the ordinary matter particles found at the heart of atoms. Totani suggests there aren’t any other astronomical phenomena that easily explain the gamma-rays observed by Fermi.

“If this is correct, to the extent of my knowledge, it would mark the first time humanity has ‘seen’ dark matter. And it turns out that dark matter is a new particle not included in the current standard model of particle physics,” Totani said. “This signifies a major development in astronomy and physics.”

While Totani is confident that what he and his colleagues have detected is the signature of dark matter WIMPs annihilating each other at the heart of the Milky Way, the scientific community in general will require more hard evidence before the book is closed on this nearly century-old mystery.

Scientists mapped the shape of a supernova for the first time ever — and it’s not what we expected: Space photo of the week

Astronomers using data from the Very Large Telescope (VLT) have revealed that the initial “breakout” phase of a supernova is elongated, not perfectly spherical.

Stars defy black hole by showing stable orbits around Sagittarius A*

An international research team led by PD Dr. Florian Peissker at the University of Cologne has used the new observation instrument ERIS (Enhanced Resolution Imager and Spectrograph) at the Very Large Telescope (VLT) facility in Chile to show that several so-called “dusty objects” follow stable orbits around the supermassive black hole Sagittarius A at the center of our galaxy.

Earlier studies had surmised that some of these objects could be swallowed up by the black hole. New data refute this assumption. The findings have been published in the journal Astronomy & Astrophysics.

Probing the quantum nature of black holes through entropy

In a study published in Physical Review Letters, physicists have demonstrated that black holes satisfy the third law of thermodynamics, which states that entropy remains positive and vanishes at extremely low temperatures, just like ordinary quantum systems. The finding provides strong evidence that black holes possess isolated ground states, a hallmark of quantum mechanical behavior.

Understanding gravity’s quantum behavior is among the biggest open questions facing modern physics. Black holes are used as laboratories for investigating quantum gravity, particularly at low temperatures where quantum effects become visible.

Prior calculations showed that black hole entropy might become negative at low temperatures, a result that appeared physically puzzling. In this work, researchers addressed the paradox by incorporating wormhole effects in the two-dimensional Jackiw-Teitelboim (JT) gravity model.

Scientists Claim to Detect Dark Matter for the First Time Ever

A team of astronomers say they may have detected dark matter, the invisible substance thought to make up over 85 percent of all matter in the universe, for the first time in history.

The claim is controversial, and the findings, published in a new study in the Journal of Cosmology and Astroparticle Physics, will need to be borne out by further observations. But at least until it gets picked apart by other physicists, it’s one of the most exciting developments in the hunt for this omnipresent specter haunting the cosmos.

“This could be a crucial breakthrough in unraveling the nature of dark matter,” study author Tomonori Totani, an astronomer at the University of Tokyo, told The Guardian.

Historic Physics Breakthrough as Scientists Catch Dark Matter Behaving in Real Time | Highlights

The universe is mostly invisible. Dark matter, the mysterious substance making up 85% of cosmic mass, has been detected through a stunning gamma-ray signal. Join us as we break down the research by a University of Tokyo astrophysicist who believes he has caught WIMP particles destroying each other a finding that redefines our place in the cosmos.

Astronomers Discover a Star That Breaks the Rules Orbiting a Silent Black Hole

Astronomers have uncovered clues to a red giant’s chaotic past by detecting subtle stellar vibrations that hint at a long-ago collision and an unexpectedly rapid spin. Astronomers at the University of Hawaiʻi Institute for Astronomy (IfA) have pieced together the turbulent history of a distant re

Dark Matter May Have Finally Been Detected in Our Galaxy’s Glow

A strange, never-before-seen glow in the halo of our galaxy may be the strongest dark-matter breadcrumb yet.

A new analysis of 15 years’ worth of data from the Fermi Gamma-Ray Space Telescope reveals a glow of unusually high-energy gamma rays that cannot easily be attributed to any known source.

According to astronomer Tomonori Totani of the University of Tokyo in Japan, it may be the radiation produced when hypothetical dark matter particles collide and wipe out one another.

We Finally Understand What Happened Before the Big Bang

For decades, we were taught the universe is 13.8 billion years old. Textbooks repeated it. Documentaries swore by it. Every model of cosmic history depended on it.
But now the numbers are breaking.

The James Webb Space Telescope is detecting galaxies that shouldn’t exist, stars older than our timeline allows, and cosmic structures so mature they overturn everything we thought we understood.
Reality is being rewritten in real time.

New evidence points to a universe that could be 26.7 billion years old – nearly double the age we believed. And if that’s true, then the biggest question becomes unavoidable.
What came before the Big Bang?

The answer is colder, emptier, and far stranger than anything in standard cosmology.
Get ready. We’re going back to the moment before everything.
