The geometry of space, the setting in which physical laws operate, may hold clues to some of the biggest unanswered questions in fundamental physics. The underlying structure of spacetime itself could ...

For more than a century, physicists have suspected that the familiar three dimensions of space might be only a small slice of ...

Could the universe have hidden dimensions we’ve yet to detect? The idea of extra dimensions has intrigued physicists for over a century, and while there’s no solid evidence to prove their existence, ...

In physics classes it is taught to include units when evaluating formulas with values and to always check that the units work out right in equations. That way we easily detect if we forgot to square a ...

Djuna Croon receives funding from the University of Sussex. Sometimes, the hardest job for a theoretical physicist is telling the story. The work in this field can be conducted entirely in the ...

Yes, OK, four dimensions – time is a dimension too, albeit an oddly unidirectional one (see “Cosmic uncertainty: Does time go both ways?“). But we’ve long thought there might be more large-scale ...
