In holographic theories, physicists may have traced the pliability of space-time to its quantum roots: a measure of ...

Even if it is impossible to travel in time, there might be more hope for sending messages backwards, a new paper argues, despite the potential paradoxes. The paper refers to the scenario in the film ...

Black holes live forever, at least according to general relativity. Once material crosses a black hole's event horizon, it is trapped forever, until the last day of cosmic time. But we know that isn't ...

Quantum computers can outperform even the best classical supercomputers thanks to quantum entanglement and superposition, but even they can’t solve some problems. A new preprint study shows how ...

A new theoretical study suggests that black holes may never fully evaporate, which contradicts an infamous Stephen Hawking theory that seems to violate fundamental laws of quantum mechanics. Instead, ...

The quantum revolution in physics — whose 100th anniversary we have just celebrated — taught us that at the most basic level the world is bizarrely different than it seems. But, we appear to only have ...
