It’s all down to general relativity, say our readers - although measuring the speed of gravity isn’t a piece of cake ...

In special relativity, the speed of light is the ultimate speed limit to the universe. Every single moving object in the universe is constrained by that fundamental limit. This isn’t something like ...

A series of new animations by a NASA scientist show just how zippy - and also torturously slow - the speed of light can be. Light-speed is the fastest that any material object can travel through ...

Alan Turing's theories about computation seem to have a startling consequence, placing hard limits on how fast or slow any ...

Researchers have unveiled a new photonic in-memory computing method that promises to advance optical computing significantly.
