Might the mere fact of creating a time machine ensure its own elimination from history? That’s the disquieting suggestion of a new theoretical framework by Andrew Jackson, a research associate at the ...

Yet according to physics, information is never destroyed. In principle, a burned book is just as readable as the original—if ...

Quantum theory fails to explain how the reality we experience emerges from the world of particles. A new take on quantum ...

“Quantum clocks running at the smallest scales were expected to lower the energy cost of timekeeping, but our new experiment ...

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 ...

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 ...

Over geological time, information loss is the norm, not the exception. The “unitarity” principle of quantum mechanics says ...

Breaking the time asymmetry remains a fundamental yet tantalizing scientific challenge. At the macroscopic level the quest has so far turned out to be fruitless, but on the other hand in the subatomic ...

The nature of time has plagued thinkers for as long as we've tried to understand the world we live in. Intuitively, we know what time is, but try to explain it, and we end up tying our minds in knots.

We break down Einstein's famous twin paradox to illustrate time dilation in special relativity. Discover how acceleration, not just velocity, causes a difference in the aging of the twins and why the ...
