How to think about a four-dimensional universe

In Einstein's famous theory of relativity the concepts of immutable space and time aren't just put aside, they're explicitly and emphatically rejected. Space and time are now woven into a coexisting fabric. That is to say, ...

Shining a light on synthetic dimensions

Humans experience the world in three dimensions, but a collaboration in Japan has developed a way to create synthetic dimensions to better understand the fundamental laws of the universe and possibly apply them to advanced ...

All your movies on a single DVD: study

Scientists unveiled new DVD technology on Wednesday that stores data in five dimensions, making it possible to pack more than 2,000 movies onto a single disc.

The strangest coincidence in physics: The AdS/CFT correspondence

Attempts to turn string theory into a workable theory of nature have led to the potential conclusion that our universe is a hologram—that what we perceive as three spatial dimensions is actually composed of only two. The ...

Why string theory requires extra dimensions

String theory found its origins in an attempt to understand the nascent experiments revealing the strong nuclear force. Eventually another theory, one based on particles called quarks and force carriers called gluons, would ...

Physicists confine electrons inside nano-pyramids

(Phys.org)—Quantum dots are nanostructures of semiconducting materials that behave a lot like single atoms and are very easy to produce. Given their special properties, researchers see huge potential for quantum dots in ...

Researchers determine the performance of multi-dimensional bits

What kinds of computers would be conceivable if physics worked differently? Quantum physicists Marius Krumm from the University of Vienna and Markus Müller from the Viennese Institute of Quantum Optics and Quantum Information ...

New technique to see crystals like never before

An international team of scientists led by the Fresnel Institute and the ESRF (European Synchrotron Radiation Facility) in Grenoble has developed a new technique allowing to observe the nanometer-sized structure of crystalline ...
