“Truly Extraordinary” — Supermassive Black Hole Found in the Last Place Scientists Expected

Dr. Sfaradi, who led the research, is a former graduate student of Prof. Assaf Horesh. “This is one of the fascinating discoveries I’ve been part of,” said Prof. Horesh. “The fact that it was led by my former student, Itai, makes it even more meaningful. It’s another scientific achievement that places Israel at the forefront of international astrophysics.”

A black hole far from home

Tidal disruption events occur when a star ventures too close to a massive black hole and is torn apart by its immense gravity.

Triplets born from proton collisions found to be correlated with each other

For the first time, by studying quantum correlations between triplets of secondary particles created during high-energy collisions in the LHC accelerator, it has been possible to observe their coherent production. This achievement confirms the validity of the core-halo model, currently used to describe one of the most important physical processes: hadronization, during which individual quarks combine to form the main components of matter in the universe.

Quarks and the gluons that bind them are the most numerous prisoners in today’s universe, locked inside protons, neutrons and mesons. However, at sufficiently high energies—such as those that existed shortly after the Big Bang or those that occur today in in the LHC accelerator—quarks and gluons are released, forming an exotic “soup”: . Under normal conditions, this plasma is not stable, and as soon as it cools down sufficiently, the quarks and gluons bind together again, producing in a process called hadronization.

New details of this fascinating phenomenon, obtained through the analysis of so-called three-body quantum correlations, have been reported by physicists from the Institute of Nuclear Physics of the Polish Academy of Sciences (IFJ PAN) in Krakow, working as part of the LHCb experiment conducted by the European Organization for Nuclear Research (CERN) in Geneva.

A new attempt to explain the accelerated expansion of the universe

Why is the universe expanding at an ever-increasing rate? This is one of the most exciting yet unresolved questions in modern physics. Because it cannot be fully answered using our current physical worldview, researchers assume the existence of a mysterious “dark energy.” However, its origin remains unclear to this day.

An international research team from the Center for Applied Space Technology and Microgravity (ZARM) at the University of Bremen and the Transylvanian University of Brașov in Romania has come to the conclusion that the expansion of the universe can be explained—at least in part—without dark energy.

In physics, the evolution of the universe has so far been described by the and the so-called Friedmann equations. However, in order to explain the observed expansion of the universe on this basis, an additional “dark energy term” must be manually added to the equations.

New Theory Suggests We’ve Been Looking for Dark Matter All Wrong

A new study suggests that Dark Matter — long thought to be completely invisible — might subtly tint light as it passes through regions filled with the elusive substance. Dark Matter, which makes up most of the Universe, might not be entirely invisible after all. According to new research from the

Can we hear gravitational-wave ‘beats’ in the rhythm of pulsars?

Pulsars suggest that ultra–low-frequency gravitational waves are rippling through the cosmos. The signal seen by international pulsar timing array collaborations in 2023 could come from a stochastic gravitational-wave background—the sum of many distant sources—or from a single nearby binary of supermassive black holes.

To tell these apart, Hideki Asada, and Professor at Hirosaki University, and Shun Yamamoto, researcher at the Graduate School of Science and Technology, Hirosaki University, propose a method that exploits beat phenomena between gravitational waves at nearly the same frequency, searching for their imprint in the tiny shifts of pulsars’ radio-pulse arrival times.

Their work has been published in the Journal of Cosmology and Astroparticle Physics.

SCP-3812: The Entity That Broke Reality | The Science of a God Who Knows It’s Fiction

What happens when awareness grows too powerful for the universe that contains it?

SCP-3812 — also known as A Voice Behind Me — is the Foundation’s ultimate paradox: a being that rewrites existence every time it tries to understand itself. This speculative science essay explores the physics, metaphysics, and philosophy behind the phenomenon. From quantum observer effects to pancomputational cosmology, from the breakdown of time to the collapse of narrative itself, we ask the ultimate question:

What if consciousness doesn’t live inside reality, but creates it?

Join us as we explore:

- The origin of Sam Howell and post-mortem evolution of awareness.
- The science of unreality and the hierarchy of dimensions.
- Schizophrenia as multiversal cognition.
- Supersession, recursion, and the limits of containment.
- The final collapse of reality into pure perception.

If you love speculative science, existential philosophy, or cosmic horror wrapped in logic, this video will change the way you think about reality.

Black holes might hold the key to a 60-year cosmic mystery

Could black holes help explain high-energy cosmic radiation?

Scientists may have finally uncovered the mystery behind ultra-high-energy cosmic rays — the most powerful particles known in the universe. A team from NTNU suggests that colossal winds from supermassive black holes could be accelerating these particles to unimaginable speeds. These winds, moving at half the speed of light, might not only shape entire galaxies but also fling atomic nuclei across the cosmos with incredible energy.

The universe is full of different types of radiation and particles that can be observed here on Earth. This includes photons across the entire range of the electromagnetic spectrum, from the lowest radio frequencies all the way to the highest-energy gamma rays. It also includes other particles such as neutrinos and cosmic rays, which race through the universe at close to the speed of light.

Two Black Holes Locked in a Death Spiral Imaged in Stunning First

The complex dance of two black holes locked in a doomed orbit has been revealed in a first-of-its-kind direct radio image.

It’s the first time astronomers have directly imaged the distinct jets of both black holes in a known binary – finally confirming the model of the double core of a galaxy called OJ 287.

In OJ 287, located some 3.5 billion light-years away, the intricate, extreme interplay between the two central supermassive black holes has been documented for decades. This is the first image to capture smoking-gun signatures of both objects, however.
