Recent progress in string theory has significantly reshaped our understanding of black holes. Traditionally seen as objects characterised by event horizons and singularities, black holes are now being ...
Recent advances in theoretical physics have highlighted the central role of chaotic dynamics in understanding black hole phenomena and string theory. Chaotic behaviour, characterised by a sensitive ...
Stephen Hawking's theory of black hole evaporation clashes with the laws of quantum mechanics. A new paper finds a way around ...
In 1980, Stephen Hawking gave his first lecture as Lucasian Professor at the University of Cambridge. The lecture was called “Is the end in sight for theoretical physics?” Hawking, who later became my ...
Quantum gravity remains one of the big missing pieces of a Grand Unified Theory that could bridge quantum field theory and general relativity. Knowing that quantum gravity solutions must resemble ...
Some things in cosmology may simply be unknowable. Why is there something rather than nothing? What lies outside the universe? What is inside a black hole? That last one has been niggling at ...
What if the mysterious substance holding galaxies together is made of leftovers from a universe that existed before our own? That is the central question posed by physicists Carlo Rovelli and ...
Ten years after scientists first detected gravitational waves emerging from two colliding black holes, the LIGO-Virgo-KAGRA collaboration, a research team that includes Columbia astronomy professor ...
A growing theory about so-called “gray holes” is beginning to attract attention among scientists. These objects could challenge current ideas about black holes and how matter behaves in extreme ...
In 2023, a subatomic particle called a neutrino crashed into Earth with such a high amount of energy that it should have been impossible. In fact, there are no known sources anywhere in the universe ...
Astronomers have detected a collision between two black holes in unprecedented detail, offering the clearest view yet into the nature of these cosmic oddities and confirming long-held predictions made ...
Yale astronomer Pieter van Dokkum and a team of researchers have discovered an object in space they call the “Infinity” galaxy — two recently-collided galaxies that, together, look like the symbol for ...
