Hawking radiation as a research area investigates the quantum-mechanical particle emission predicted to occur at black hole event horizons, integrating quantum field theory in curved spacetime, general relativity, and thermodynamics. It explores the derivation, robustness, and extensions of Hawking’s original calculation, its implications for black hole thermodynamics, entropy, and temperature, and its central role in the black hole information loss problem. The field also includes studies of analog Hawking radiation in laboratory systems, possible observational signatures of evaporation for primordial or microscopic black holes, and attempts to embed the phenomenon in candidate quantum gravity frameworks such as string theory and holography.
Black holes, despite their extreme nature, are described by surprisingly few basic parameters: their mass, charge and spin. Two black holes may have formed for completely different reasons and passed through very different ...
In 1974, Stephen Hawking made a prediction that transformed our understanding of black holes. Black holes, he showed, are not truly black: They slowly lose energy through a quantum process now known as Hawking radiation. ...
Of the known things in the universe, black holes are among the most extreme. They pack huge amounts of mass densely into a small area, producing gravity that is so strong that even light cannot escape. To describe their properties, ...

Hawking radiation is a form of radiation emitted by black holes, as theoretically predicted by Stephen Hawking. It suggests that black holes do not merely swallow matter—as had previously been assumed—but also emit very faint ...

There are multiple ways to form black holes. The one most commonly taught in high school physics classes is that they are created from the collapse of a dying star. But there is another class of black holes, known as primordial ...

Galactic collisions are events of breathtaking proportions. The supermassive black holes (SMBHs) at their centers plunge into a chaotic orbital dance that eventually coalesce into a single remnant. On their way to that point, ...

Black holes, regions in space where gravity is so strong that nothing can escape, have been widely studied over the past decades, due to their unique and intriguing properties. Einstein's theory of general relativity predicts ...
Black holes are regions in space where gravity is so strong that nothing, even light, can escape. Einstein's theory of general relativity breaks down inside black holes, either by the presence of a so-called "curvature singularity" ...
Black holes live forever, at least according to general relativity. Once material crosses a black hole's event horizon, it is trapped forever, until the last day of cosmic time. But we know that isn't true. General relativity ...

Theoretical physicists in the US have discovered a "speed limit" on the time taken for quantum information to spread through larger systems. Publishing their results in Physical Review Letters, Amit Vikram and colleagues ...
