Geometry has surprising consequences for the behaviour of matter. Living in three dimensions, we're familiar with liquids that abruptly freeze into solids, or crystals under pressure that suddenly ...

Gravity is by far the weakest of nature’s four fundamental forces, and physicists have spent decades asking a deceptively ...

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 ...

What if the Universe – and fundamentally, space itself – were like a pile of laundry? Have one. See this laundry pile? Looks just like our universe. No? Here, have another. See it now? It’s got three ...

We tend not to dwell on the fact that we exist in three dimensions. Forwards-back, left-right, up-down; these are the axes on which we navigate the world. When we try to imagine something else, it ...

We live in a three-dimensional reality. Because of that, it's pretty hard to imagine what a four-dimensional reality might be like, but that isn't stopping physicists from trying to figure it out. A ...

Researchers have been looking at everything, including supernovas, trying to uncover the mysteries of dark matter. Recent scientific studies suggest that dark matter might not be a particle hiding in ...
