In one particularly weird document, titled Negative Mass Propulsion, the authors propose nuking the Moon, as well as building ...

Gravitational waves are energy-carrying waves produced by the acceleration or disturbance of massive objects. These waves, which were first directly observed in 2015, are known to be produced during ...

Planets orbiting dead stars known as white dwarfs might be able to remain habitable thanks to general relativity subtly altering their motion. When stars like our sun run out of fuel, they expand and ...

Monday and Thursday 12–14 in M4. After a quick introduction to Special Relativity (mechanics and electrodynamics at a finite speed of light, mathematically modelled with a quadratic form of signature ...

Are black holes, made famous by Stephen Hawking’s writings and research, actually real? Gravitational-wave astronomy is celebrating ten years of success this September 2025. And just in time for the ...

The origin of our Universe remains one of the greatest enigmas of science, a question that seems to defy the limits of our physical understanding. For decades, cosmologists have struggled with the ...

When you buy through links on our articles, Future and its syndication partners may earn a commission. An illustration of a black hole accretion disk glowing with radiation. New research suggests that ...

Diagrammatic representation of the entropic quantum gravity action. The action for gravity is given by the quantum relative entropy between the metric of the manifold and the metric induced by the ...

Theoretical physicists have proposed a potential solution to one of the most puzzling problems in modern physics: the black hole singularity paradox. By modifying Einstein's theory of general ...
