Physicists have proposed a new model of space-time based on string theory to explain dark energy. Their hypothesis suggests that, at extremely small scales, space and time behave differently from how ...

Visualization of the allowed values of "dial settings" in the scattering amplitudes that describe the probability for particles to interact in the models introduced in this new work. The regions in ...

Black holes, the densest objects in the universe, eat up anything that comes too close, even light. Is there anything left inside these behemoths that could reveal what they devoured in the first ...

Scientists successfully borrow concepts from string theory to explain the network architecture of branching biological systems like neurons ...

For decades, scientists, philosophers and science fiction writers have been fascinated by the idea of parallel universes — realms that may exist beyond our own, each potentially with its own version ...
