Gravity Seems Holographic. What Does That Mean for Reality?

Automated excerpt

This geometry is known as anti-de Sitter (AdS) space. And the AdS/CFT correspondence essentially guarantees that anti-de Sitter space — which happens to be the space physicists understand best — is holographic. Holographers shy away from this interpretation because they don’t have a full quantum handle on space — even anti-de Sitter space.
