AdS/CFT suggests that our three-dimensional universe can be modeled by a two-dimensional surface. AdS (Anti-de Sitter space) ...

For more than a century, physicists have suspected that the familiar three dimensions of space and one of time might be only ...

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 ...

Quantum theory fails to explain how the reality we experience emerges from the world of particles. A new take on quantum ...

Scientists are investigating the existence of hidden dimensions in our universe, which could potentially revolutionize our ...

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

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.

Encouraged by successes in understanding black holes, theoretical physicists are applying what they’ve learned to whole ...

If so, laws might change when the universe itself changes phase. In the early universe, as temperatures and densities shifted, forces split apart from a unified origin. What we call “laws” may be like ...

Physicist Michael Pravica of the University of Nevada, Las Vegas, proposes that our awareness isn’t fully tethered to the three spatial dimensions we perceive. Instead, in rare moments of deep thought ...
