Why the universe might be a hologram

A quarter century ago, physicist Juan Maldacena proposed the AdS/CFT correspondence, an intriguing holographic connection between gravity in a three-dimensional universe and quantum physics on the universe's two-dimensional ...

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 ...

New theory claims to unite Einstein's gravity with quantum mechanics

A radical theory that consistently unifies gravity and quantum mechanics while preserving Einstein's classical concept of spacetime has been announced in two papers published simultaneously by UCL (University College London) ...

The miraculous effect of music: Concerts bind people together

Why does music exist? Some researchers believe that music is so widespread across human cultures because it brings people together. The theory is that during evolution, human groups who were musical worked better together, ...

Do the bump: Scientists perfect miniaturized technique to generate precise wavelengths of visible laser light

In research, sometimes the bumpy path proves to be the best one. By creating tiny, periodic bumps in a miniature racetrack for light, researchers at the National Institute of Standards and Technology (NIST) and their colleagues ...

First experimental evidence of hopfions in crystals: Research opens up new dimension for future technology

Hopfions, magnetic spin structures predicted decades ago, have become a hot and challenging research topic in recent years. In a study published in Nature, the first experimental evidence is presented by a Swedish-German-Chinese ...

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, ...
