By stopping black holes from fully evaporating, hidden dimensions may solve a cosmological paradox.

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 ...

The issue stems from a deeper conflict within statistical physics. A key principle used to explain why time appears to move ...

Why the double-slit still haunts quantum physics I see the double-slit experiment as the simplest possible machine for manufacturing paradox. Fire individual particles of light or matter at a barrier ...

Stephen Hawking's theory of black hole evaporation clashes with the laws of quantum mechanics. A new paper finds a way around ...

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 ...
