As the universe expands, it feels like it must be spreading out from some initial point. But a physicist explains why that’s not how it works. Hint: space-time is involved.

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 ...

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 ...

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 ...

An international team of scientists has come up with a new explanation for why space occupies three dimensions. The theory hinges upon flux tubes, which are comprised of quarks held together by gluons ...

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 ...

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 ...

Forbes contributors publish independent expert analyses and insights. The Universe is out there, waiting for you to discover it. Holograms are some of the most interesting "flat" objects humans can ...

This could be the way the world ends. First, a pair of cosmic protons smash together at unimaginable speeds. The tremendous energy of their crash would create a tiny, ephemeral black hole, so small ...
