"The singularity is the most mysterious and problematic part of a black hole. It's where our concepts of space and time ...

A new theory links gravity to quantum entropy and introduces the G-field, possibly explaining dark matter and cosmic ...

A complete theory of quantum gravity remains one of the biggest challenges ... Under certain conditions, these modified ...

A new model has been proposed that challenges the long-standing belief that black holes contain a singularity, a region where space and time break down. This theory suggests that black holes could ...

Physicists have proposed a new model of space-time that may provide the 'first observational evidence supporting string ...

one of the leading candidates for a quantum theory of gravity. Unlike the Standard Model, which treats elementary particles as point-like, string theory proposes that they are actually tiny ...

While general relativity describes gravity, quantum theory deals with the other three forces. This creates a problem: "As early as the 1930s, it was recognized that the two theories do not fit ...

The problems of gravity and acceleration would not go away. After thinking about the problems for 10 years, he published the general theory of relativity. In it, he suggested that gravity is not a ...

Using the mathematics of Einstein's 1915 theory of gravity, called general relativity, scientists can model the interior of a black hole. The problem is that, when they do this, general relativity ...
