A team of quantum physicists has taken a concept that once lived purely in equations and turned it into hardware reality, ...

Take, for instance, quantum entanglement, which says that the state of one particle can be determined by examining the state ...

Does our universe exist in more than just three dimensions? Probably not on large scales, according to new research published July 23 in the Journal of Cosmology and Astroparticle Physics. The study ...

Recent scientific discussions suggest that the fourth dimension might be concealed within our everyday perception of reality, challenging conventional views of space and time. This idea intersects ...

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 ...

This story is a supplement to the feature "Using Causality to Solve the Puzzle of Quantum Spacetime" which was printed in the July 2008 issue of Scientific American. A Whole New Dimension to Space In ...

There are a few rules in the Universe that seem likely to never be broken. Particles cannot travel faster than the speed of light in a vacuum; the entropy of a closed system can never decrease; energy ...
