‘’As a result, it’s nonsensical to ask what happens to space-time beyond the Cauchy horizon because space-time, as it’s regarded within the theory of general relativity, no longer exists. “This gives one a way out of this philosophical conundrum,” said Dafermos.
Mathematicians have disproved the strong cosmic censorship conjecture. Their work answers one of the most important questions in the study of general relativity and changes the way we think about space-time.
According to a straightforward interpretation of general relativity, the Big Bang wasn’t the start of ‘everything’.
Taking Einstein’s famous equations at face value and making as few assumptions as possible, a team of researchers has rewound the clock on our Universe to find it wouldn’t lead to a stopping point at all, but would take us through a different kind of beginning into a flipped space.
To understand what all the fuss over the Big Bang is, we need to rewind a bit to understand why physicists think it may not have been the start of everything.
Although it’s impossible (at least for now) to travel back in time to see the Big Bang, The New York Times has provided its readers the closest simulation of the experience via its latest augmented reality feature.
On Friday, the Times published “It’s Intermission for the Large Hadron Collider,” an interactive story that gives readers a virtual tour of the Large Hadron Collider at the European Center for Nuclear Research (CERN) in Switzerland and explores its most famous discovery, the Higgs boson.
An international team of scientists has published a new study which describes how the Hubble Space Telescope can be used to ‘see’ dark matter.
An international team of scientists believe that they have finally found a way to “see” dark matter, which is an invisible and elusive substance that makes up 85 percent of the matter in the universe.
As the Daily Mail has reported, in a new study, astronomers hailing from Spain and Australia have written that by using data collected from the Hubble Space Telescope, astronomers may be able to use starlight from faraway galaxy clusters so that they can spot dark matter and eventually map this mysterious substance.
Nope. Too late already. It’s been molten long ago already ha…
Groundbreaking physicist Stephen Hawking left us one last shimmering piece of brilliance before he died: his final paper, detailing his last theory on the origin of the Universe, co-authored with Thomas Hertog from KU Leuven.
The paper, published in the Journal of High Energy Physics in May, puts forward that the Universe is far less complex than current multiverse theories suggest.
It’s based around a concept called eternal inflation, first introduced in 1979 and published in 1981.

Black holes are great at sucking up matter. So great, in fact, that not even light can escape their grasp (hence the name).
But given their talent for consumption, why don’t black holes just keep expanding and expanding and simply swallow the Universe? Now, one of the world’s top physicists has come up with a new explanation.
Conveniently, the idea could also unite the two biggest theories in all of physics.
