Spacetime isn’t something that exists; it’s a model for describing how events happen. Treating events as objects creates ...

For obvious reasons, we do not know what the inside of a black hole looks like. But thanks to theoretical physics, we can ask ...

The rules of time-travel have been debated by scientists and sci-fi fans alike for years, but now a student physicist has been able to "square the numbers" to show how paradox-free time travel is ...

Stephen has degrees in science (Physics major) and arts (English Literature and the History and Philosophy of Science), as well as a Graduate Diploma in Science Communication. Stephen has degrees in ...

A paradox that puzzled a generation of solar and atomic physicists – and occasionally pitted theories from one field against the other – has been resolved. The paradox concerns the polarization of ...

Black holes of string theory - fuzzballs - are perhaps even weirder than the regular type. Black holes are a paradox. They are paradoxical because they simultaneously must exist but can’t, and so they ...

The information loss paradox challenges physics by suggesting black holes may destroy information, a concept first raised by Stephen Hawking in 1976.

Falling into a black hole means facing extreme stretching, known as spaghettification, due to immense tidal forces. While ...
