Did astronomers see a black hole explode? An 'impossible' particle that hit Earth in 2023 may tell us
An incredibly energetic "impossible" particle that hit Earth in 2023 may have been debris from an exploding primordial black hole formed during the Big Bang. If that is the case, then it could prove ...
How is lightning initiated in thunderclouds? This is difficult to answer – how do you measure electric fields inside large, dangerously charged clouds? It was discovered, more or less by coincidence, ...
This artist's concept takes a fanciful approach to imagining small primordial black holes. In reality, such tiny black holes would have a difficult time forming the accretion disks that make them ...
The last gasp of a primordial black hole may be the source of the highest-energy "ghost particle" detected to date, a new MIT study proposes. In a paper appearing today in Physical Review Letters, MIT ...
Dark matter is a ghostly substance that astronomers have failed to detect for decades, yet which we know has an enormous influence on normal matter in the universe, such as stars and galaxies. Through ...
