Our universe may be hiding extra dimensions just beyond the reach of current experiments — and they could be the key to unlocking two of the most stubborn mysteries in physics. A new theoretical study ...

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

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

Physicists explore whether the universe hides extra dimensions. These tiny, curled-up or warped dimensions could explain ...

Neil Downie believes that supporting students to devise, build and test their own projects can help to get them and their teachers interested in and enjoying physics Practical solutions Students who ...

Google updated its search engine and Lens tool with new features to help you visualize and solve problems in more difficult subjects like geometry, physics, trigonometry and calculus. The update ...

Clocks might be far more fundamental to physics than we ever realized. A new theory suggests what we see around us – from the smallest of quantum actions to the cosmic crawl of entire galaxies – could ...
