A Tiny Black Hole Goes Through Our Solar System Every Decade

Proving primordial black holes. If researchers want to prove the theory of primordial black holes, they have to confirm that the wobble they saw of Mars wasn''t caused by another source like a passing asteroid. "State-of-the-art simulations of the solar system include more than a million objects, each of which has a tiny residual effect," study co-author and

Could Atom-Sized Black Holes Be Detected in Our Solar System?

Scientific American has surprising news about the possibility of black holes the size of an atom but containing the mass of an asteroid — the so-called "primordial black holes" formed after the birth of the universe which could solve the ongoing mystery of the missing dark matter. These atom-sized black holes "may fly through the inner solar system about once a

Black Hole Types

Types of Black Holes Astronomers generally divide black holes into three categories according to their mass: stellar-mass, supermassive, and intermediate-mass. The mass ranges that define each group are approximate, and scientists are always reassessing where the boundaries should be set. Cosmologists suspect a fourth type, primordial black holes formed during the birth of

Probing primordial black holes and dark matter clumps in the Solar

We show that the Global Navigation Satellite System (GNSS) and gravimeters on Earth and in space can potentially offer the most accurate direct measurement of local density of near-Earth asteroid-mass primordial black holes (PBHs) and dark matter (DM) clumps in the Solar System by means of gravitational influence. Using semianalytical methods and Monte Carlo

In cosmology, primordial black holes (PBHs) are hypothetical black holes that formed soon after the Big Bang. In the inflationary era and early radiation-dominated universe, extremely dense pockets of subatomic matter may have been tightly packed to the point of gravitational collapse, creating primordial black holes without the supernova compression typically needed to make blac

Primordial Black Holes Could Be Detected Thanks to Their

The team worked out the rate at which a primordial black hole should pass through the Solar System, based on the amount of dark matter that is estimated to reside in a given region of space and the mass of a passing black hole, which in this case, they assumed to be as massive as the largest asteroids in the Solar System, consistent with other

A ''primordial'' black hole may zoom through our solar system

In principle, a primordial black hole''s gravitational pull "could produce wobbles in the orbits of objects in the solar system that are big enough for us to measure." The scientists ended up focusing on primordial black holes flying near the inner planets of the solar system — Mercury, Venus, Earth and Mars .

Little black holes in our solar system could finally confirm dark

Primordial black holes and Mars. Why does Mars, out of all the planets, offer the best chance of detection? Sarah Geller, a postdoctoral researcher at the University of California at Santa Cruz and one of the study''s co-authors, explains, "Primordial black holes don''t

Primordial Black Holes in the Solar System

Primordial Black Holes in the Solar System Primordial black holes (PBHs) as a dark matter (DM) candidate have been studied for half a century (Carr & Green 2024), gaining special attention after the first direct detection of gravitational waves from binary black hole mergers

A wobble from Mars could be sign of dark matter, MIT study finds

The team worked out the rate at which a primordial black hole should pass through the solar system, based on the amount of dark matter that is estimated to reside in a given region of space and the mass of a passing black hole, which in this case, they assumed to be as massive as the largest asteroids in the solar system, consistent with other
