A new study shows we may be living inside a black hole.

This study might just change how we see the universe forever.

Researchers using the James Webb Space Telescope’s JADES survey analyzed the rotation of 263 distant galaxies. In a universe that’s truly random, scientists expected galaxy spins to be evenly split—half clockwise, half counterclockwise. But two-thirds of those galaxies rotate the same way, pointing to a surprising asymmetry that defies expectations and challenges long-held beliefs about how the universe works.

This unexpected finding may have profound implications. One theory posits that the universe was born with a spin, fundamentally altering models of its origin. Another supports a radical idea known as black hole cosmology, which suggests our entire universe exists within the event horizon of a larger, parent black hole. If this is true, it could transform our understanding of cosmic evolution, timelines, and even gravity itself. With more questions than answers, this study opens the door to a new era of cosmic exploration—and a deeper look into the strange, spinning fabric of reality.

Turns out, Earth's inner core isn't just a solid ball of nickel and iron but consists of two layers.

Researchers have confirmed the existence of this innermost inner core using a unique type of seismic wave that travels through and bounces back and forth within the Earth's interior, providing valuable data about the core's structure.

By analyzing seismic waves from earthquakes of magnitude 6 or larger that occurred over the past decade, the scientists identified 16 events with waves bouncing through the inner core multiple times.

Seismic data revealed that this inner heart is approximately 600 kilometers across, about half the diameter of the full inner core. Understanding the core is essential because it generates Earth's magnetic field, which protects us from solar particles and radiation. Earth’s core, which is about 6,600 kilometers across, consists of a liquid outer core and a solid inner core.

As iron-rich fluid cools and crystallizes in the outer core, it forms a solid center, generating a magnetic field.

The exact origins and timing of the core's formation remain uncertain, but it plays a crucial role in Earth's history. The core's magnetic field has likely undergone numerous pole reversals over the planet's lifespan. Seismic data suggests the presence of a hidden heart in the innermost core, potentially a long-preserved remnant of the core's early formation.

CERN discovers antihyperhelium-4, the heaviest antimatter particle to date.

Scientists at CERN’s Large Hadron Collider have discovered the heaviest antimatter particle ever observed: antihyperhelium-4.

This exotic particle, the antimatter counterpart of hyperhelium-4, contains two antiprotons, an antineutron, and an antilambda particle. The breakthrough offers insights into the extreme conditions of the early universe and sheds light on the baryon asymmetry problem — why our universe is dominated by matter despite matter and antimatter being created in equal amounts during the Big Bang.

The discovery was made using lead-ion collisions at the LHC, recreating the hyper-hot environment of the newborn universe. Machine learning models analyzed the data, identifying antihyperhelium-4 particles and precisely measuring their masses.

While the experiment confirmed that matter and antimatter are created in equal portions, the mystery of what tipped the cosmic balance remains unsolved. With ongoing upgrades to the LHC, more groundbreaking discoveries in antimatter research could be on the horizon.

A team of physicists says there may be another universe running backward in time prior to the Big Bang:

Scientists, led by University of Edinburgh professor Neil Turok, have a new theory about how our universe operates. They say that another universe may have existed before the Big Bang, moving in reverse through time.

They call it the "anti-universe," and it's basically a reflection of our own with oppositional time.

The paper was accepted for publication in the journal Annals of Physics.

This elegant idea could help explain some of the biggest mysteries in cosmology, including the imbalance between matter and antimatter and the nature of dark matter, while offering an alternative to prevailing theories Turok describes as overly complex.

The theory builds on the concept of symmetry in physics, where particles, forces, and even time have mirrored opposites.

However, our universe appears lopsided — time moves only forward, and particles outnumber their antimatter counterparts. Turok's "mirror hypothesis" restores that balance, envisioning a universe that mirrors ours in perfect symmetry. "The progress we have already made convinces me that there are alternatives to the standard orthodoxy," Turok said, urging cosmology to break free of its current constraints

Former NASA Physicist's New Experiments May Prove We Live in a Simulation:

Ever wondered if reality is just an elaborate simulation? Former NASA physicist Thomas Campbell has dedicated his work to answering that mind-bending question.

Through his non-profit, Campbell has designed a series of experiments to test whether our universe is being "rendered," much like a video game. His approach offers a fresh spin on the famous double-slit experiment, which explores the wave-particle duality of light and matter.

Campbell's hypothesis suggests that without an observer—or a "player"—the recorded information about the universe never actually exists. This aligns with the idea of a "participatory universe," where reality is only created when someone interacts with it, much like how objects in a video game pop into existence as you move through the environment.

While the simulation hypothesis is not new, Campbell’s scientific background and unconventional experiments make his exploration of this theory especially compelling. Could our world really just be pixels in a cosmic game? Campbell’s experiments might get us one step closer to the truth.
