In this video, we explore the relationship between string theory and quantum field theory (QFT). QFT is a mathematical framework that describes nearly all particles and forces in the universe but ...

For more than a century, physicists have suspected that the familiar three dimensions of space and one of time might be only a sliver of reality. Extra dimensions, if they exist, would not just be a ...

String theory is a purported theory of everything that physicists hope will one day explain … everything. All the forces, all the particles, all the constants, all the things under a single ...

Did the early universe have just one spatial dimension? That's the mind-boggling concept at the heart of a new theory. Researchers now describe a test that could prove or disprove the "vanishing ...

Quantum theory and Einstein's theory of general relativity are two of the greatest successes in modern physics. Each works extremely well in its own domain: Quantum theory explains how atoms and ...

Current theories suggest that W and Z bosons acquire mass from interactions with the Higgs scalar field, but a new study suggests that the higher dimensional structure of spacetime could be the actual ...

What if time were the only truly fundamental dimension of our Universe? A recent theory proposes a radically different vision of reality, where time has three dimensions. This approach challenges our ...

Receive emails about upcoming NOVA programs and related content, as well as featured reporting about current events through a science lens. The engineer whips out a protractor and straightedge. That’s ...

A refreshingly simple new idea has emerged in the complicated world of high energy physics. It proposes that the early universe was a one-dimensional line. Not an exploding sphere, not a chaotic ball ...

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 ...
