What If Our Understanding of Gravity Is Wrong?
The search for dark matter has lasted more than half a century, but a growing line of thought argues the real problem may be gravity itself. Instead...
What Happens If A Black Hole Hits Earth?
A black hole hitting Earth is unlikely to be noticed in real time—but if primordial black holes exist in the “asteroid-mass” range, they could still...
Is Dark Matter Made of Particles?
Dark matter is almost certainly made of particles from a “dark sector” that barely interact with ordinary matter—so it neither emits nor absorbs...
Black Holes from the Dawn of Time
Black holes may have formed in the universe’s first moments—and if they did, some could still exist today as “primordial black holes” (PBHs). The key...
What If There's A Black Hole Inside The Sun? | Hawking Stars
A captured primordial black hole inside a star would quietly change the star’s internal physics for billions of years—eventually forcing it into a...
How Many Black Holes Are In The Solar System?
Dark matter may be detectable without particle detectors or telescopes—by treating the solar system itself as a giant “primordial black hole” (PBH)...
What If Dark Matter Is Just Black Holes?
Dark matter may not be made of black holes after all. By checking how black holes would have to be distributed—matching the dark-matter halo around...
Are Axions Dark Matter?
Axions are a leading candidate for solving a major mismatch between quantum theory and experiment in the strong nuclear force—and they may also...
No Dark Matter = Proof of Dark Matter?
Dark matter may be real after all—not because a particle has been detected, but because some galaxies appear to contain little or none of it,...
Are Dark Matter And Dark Energy The Same?
A new proposal tries to unify dark matter and dark energy by treating them as outcomes of the same underlying phenomenon: negative mass. The idea,...
How I Became Particle Physicists’ Enemy #1
Particle physicists’ push for ever-larger colliders is portrayed as a costly detour driven by decades of “nonsense” theory-making—an approach that,...
Most of Reality Is Invisible. We May Finally Be About to Reveal It.
The Large Hadron Collider may be able to “open a portal” to a hidden dark sector—not by creating black holes or wormholes, but by producing Higgs...
Did One Single Neutrino Just Prove Stephen Hawking Right?
A single ultra-high-energy neutrino detection is being floated as a potential clue to Hawking’s long-standing prediction that black holes...
New Data Bring Trouble For Theory of Universe
A new radio-telescope analysis claims the Solar System is moving about 3.7 times faster than the standard cosmological model predicts—an apparent...
Strange New Observations Reveal Major Clue About Dark Matter
Small dwarf galaxies appear to be clustering together more than standard dark matter models predict—an anomaly that points toward dark matter having...
Action at a Distance Can Explain Dark Matter, Physicists Show
Physicists may have been chasing the wrong culprit for the universe’s missing mass: instead of inventing dark matter, some researchers are proposing...
Magnetic Charges Could Actually Exist, Physicists Find
Magnetic monopoles—hypothetical particles carrying only a single magnetic pole (north or south)—have long been attractive because they would make...
How long will it take to solve the 5 big physics problems?
Progress in fundamental physics may accelerate in the next decade or two, but not because long-sought “theories of everything” are suddenly within...
New Theory: Space has Memory Which Appears Like Dark Matter
A new line of theoretical work proposes that spacetime stores a “memory” of matter that passes through it—and that this stored information could...
Nuclear Fusion Reactors Could Produce Dark Matter, Physicists Show
Fusion reactors might be able to generate axions—an especially popular dark-matter candidate—at rates high enough to measure, making nearby...
Is Gravity Modified or is it Dark Matter after all?
The latest push in the long-running debate over whether gravity needs modification—or whether unseen dark matter is the better fit—turns on a single...
