Smooth" or grainy? Is space-time continuous or is it made up of very fine (10-35 metres on the "Planck scale") but discrete grains, if we look at it very close up ? If the latter were true, scientists think, this would lead ...

A pair of researchers at Surrey University has attempted to show what a bicycle moving at near the speed of light might look like to a human observer. In their paper published in the journal Proceedings of the Royal Society ...
Complicated statistical behaviour observed in complex systems such as early universe can often be understood if it is broken down into simpler ones. Two physicists, Petr Jizba (currently affiliated with the Czech Technical ...
