To most of us, time feels as solid as the phone alarm that drags us out of bed or the calendar that fills up faster than we ...

By studying ripples in space-time, physicists are testing wheather dark energy might stem from hidden dimensions, elusive ...

A mathematical test for the nature of space-time – the fabric of physical reality – may be the first step towards novel computer-like devices that process information using gravity. Eleftherios-Ermis ...

A new physics paper takes a step toward creating a long-sought "theory of everything" by uniting gravity with the quantum world. However, the new theory remains far from being proven observationally.

How many electrons are there in the Universe? One bold theory suggests that there could only be one, although this theory has ...
