1 day ago · In a new study, MIT physicists propose that if most of the dark matter in the universe is made up of microscopic primordial black holes — an idea first proposed in the 1970s — then these gravitational dwarfs should zoom through our solar system at least once per decade. A flyby like this, the researchers predict, would introduce a wobble ...
1 day ago · Credit: LIGO. A new study published in Physical Review Letters (PRL) proposes using gravitational wave detectors like LIGO to search for scalar field dark matter. Dark matter, an elusive form of ...
4 days ago · If we see it, that would count as a real reason to keep pursuing this delightful idea that all of dark matter consists of black holes that were spawned in less than a second after the Big Bang and have been streaming around the universe for 14 billion years.” Kaiser and his colleagues report their findings today in the journal Physical Review D.
3 days ago · A new deep-learning algorithm is set to be unleashed upon images of galaxy clusters in search of the telltale signs of this invisible substance that strangely makes up 85% of all matter in the...
4 days ago · But Mars seemed to offer a clearer picture. The researchers found that if a primordial black hole were to pass within a few hundred million miles of Mars, the encounter would set off a “wobble,” or a slight deviation in Mars’ orbit. Within a few years of such an encounter, Mars’ orbit should shift by about a meter—an incredibly small ...
3 days ago · By comparing Hubble Wide Field Camera 3 near-infrared exposures taken in 2009, 2012, and 2023, astronomers found evidence for flickering supermassive black holes in the hearts of early galaxies. One example is seen as a bright object in the inset.
