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 ...

BUFFALO, N.Y. — Did the early universe have just one spatial dimension? That’s the mind-boggling concept at the heart of a theory that University at Buffalo physicist Dejan Stojkovic and colleagues ...

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, ...

Dark matter could be even weirder than anyone thought, say cosmologists who are suggesting this mysterious substance that accounts for more than 80% of the universe's mass could interact with itself. ...

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 ...
