Physicists have determined that most of the universe is dark matter -- invisible to us but affecting the universe anyway.

In 1919, physicist Theodor Kaluza hypothesized that extra dimensions might solve some outstanding problems in physics. And ...

Physicists know that something unseen is sculpting the cosmos, outweighing ordinary matter by roughly a factor of five, yet ...

Researchers attempting to solve the problem of dark matter have proposed a particle that can travel to an unseen fifth dimension. The work is entirely hypothetical, as it attempts to explain a type of ...

A Princeton scientist with an interdisciplinary bent has taken two well-known problems in mathematics and reformulated them as a physics question, offering new tools to solve challenges relevant to a ...

Our standard model of elementary particles and forces has recently become as close to “complete” as we could conceivably ask for. Every single one of the elementary particles — in all their different ...

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 ...

Physics education is a subject that is almost as big as physics itself, and in some ways it is even more complex. Although the laws of physics are the same in Belfast, Bologna and Berlin, the way in ...
