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 ...

The origins of the black hole information paradox

While physics tells us that information can neither be created nor destroyed (if information could be created or destroyed, then the entire raison d'etre of physics, that is to predict future events or identify the causes ...

Why Einstein must be wrong: In search of the theory of gravity

Einstein's theory of gravity—general relativity—has been very successful for more than a century. However, it has theoretical shortcomings. This is not surprising: the theory predicts its own failure at spacetime singularities ...
