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

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 ...

The idea that a hidden fourth dimension could be woven into everyday reality is no longer just a science‑fiction trope.

Physicists who work with a concept called string theory envision our universe as an eerie place with at least nine spatial dimensions, six of them hidden from us, perhaps curled up in some way so they ...

In 1919, physicist Theodor Kaluza hypothesized that extra dimensions might solve some outstanding problems in physics. And while we haven't found any evidence yet for anything outside our normal ...

Did the early universe have just one spatial dimension? That’s the mind-boggling concept at the heart of a theory that UB physicist Dejan Stojkovic and colleagues proposed in 2010. They suggested that ...

Physicists have taken a bold step beyond Einstein's special theory of relativity, proposing an expansion of special relativity that includes observers moving faster than light. This fresh perspective ...

Some scientists think quantum mechanics may be working in a lower-dimensional setting, giving us the illusion of our 3-dimensional universe. This idea changes the nature of our perceived reality, ...

When you buy through links on our articles, Future and its syndication partners may earn a commission. A technician stands Inside one of the protoDUNE detectors during its construction at CERN. Could ...

You experience daily life in three spatial dimensions (and one dimension of time). You move forward and backward, step left and right, and go up and down stairs as you move around your world. But ...

The universe began with an unimaginably hot, dense state. Inflation rapidly expanded the universe's size. Before inflation, the universe existed in a period called the GUT era where forces were ...

Not every existential crisis ends in dread. In the best cases, it opens new dimensions. When Turkish-Austrian artist Alea Pinar De Pre conceptualized her most recent collections of works, it was to ...
