‘Cosmic fossils’ left by black holes created before the big bang may still shape the universe

Beyond the Big Bang: The Rise of the ‘Big Bounce’ and the Future of Cosmology For decades, the Big Bang has been the undisputed origin story of our universe. We’ve been taught that everything—every star, every planet, and every atom in your body—exploded from a single, infinitely dense point. But the cracks in this theory … Read more

Undergraduate students built a cavity detector to search for axion dark matter

Beyond the Billion-Dollar Machine: The Rise of ‘Small Science’ in the Hunt for Dark Matter For decades, the narrative of modern physics has been one of scale. To find the smallest particles in the universe, we built the largest machines imaginable. From the sprawling tunnels of the Large Hadron Collider (LHC) to the massive underground … Read more

A Galaxy Composed Almost Entirely of Dark Matter Has Been Confirmed

The Ghostly Galaxy CDG-2: A Window into the Universe’s Hidden Mass Astronomers have identified a remarkable cosmic anomaly: a faint galaxy, designated CDG-2 (Candidate Dark Galaxy-2), composed of approximately 99.9% dark matter. Located about 300 million light-years away in the Perseus galaxy cluster, this galaxy challenges our understanding of galactic formation and the distribution of … Read more

Something Mysteriously Powerful Slammed Into Earth in 2023. Scientists Now Have a Theory

Hunting Ghost Particles: Could Exploding Primordial Black Holes Explain a Cosmic Mystery? Astrophysicists are grappling with an intriguing puzzle: the detection of an extraordinarily powerful neutrino by the KM3NeT detector, a signal that simultaneously eluded the IceCube Neutrino Observatory. This discrepancy has led researchers to explore unconventional explanations, including the possibility of exploding primordial black … Read more

Dark matter began hot and later cooled to shape the Universe

Dark Matter’s Fiery Birth: Rewriting the Story of the Universe For decades, the prevailing theory held that dark matter – the invisible substance making up roughly 85% of the universe’s mass – was “cold,” meaning it moved slowly after the Big Bang. This slow pace was considered crucial for the formation of galaxies and the … Read more

European Space Agency releases trove of data that might help us understand dark matter

The Enigmatic Dance of Dark Matter and Dark Energy Unveiling the vast cosmic web, the Euclid mission is on a quest to decode two of the universe’s most profound mysteries: dark matter and dark energy.
