Hawking: Black holes store information

Black holes preserve information about the stuff that falls into them, according to Prof Stephen Hawking. Physicists have long argued about what happens to information about the physical state of things that are swallowed up by black holes. This information was thought to be destroyed, but it turned out that …

Dozen black holes found at galactic centre

A dozen black holes may lie at the centre of our galaxy, the Milky Way, researchers have said. A new analysis provides support for a decades-old prediction that “supermassive” black holes at the centres of galaxies are surrounded by many smaller ones. However, previous searches of the Milky Way’s centre, …

Mount Etna is ‘sliding towards the sea’

Europe’s most active volcano, Mount Etna, is sliding towards the sea. Scientists have established that the whole structure on the Italian island of Sicily is edging in the direction of the Mediterranean at a rate of 14mm per year. The UK-led team says the situation will need careful monitoring because …

How effective are earthquake early warning systems?

Earthquake early warning detection is more effective for minor quakes than major ones. This is according to a new study from the United States Geological Survey. Seismologists modelled ground shaking along California’s San Andreas Fault, where an earthquake of magnitude 6.5 or more is expected within 30 years. They found …
