Universal Illusion? Juan Maldacena's holographic universe

Universal Illusion? Juan Maldacena's holographic universe | Science News | Scoop.it

To make things clear - Maldacena's universe is not like the one we actually live in! It's a model, a toy universe, which comes complete with its own physics. It's a hologram because all the physical goings-on inside it can be described by a physical theory that's only defined on the boundary. What's more, it's a universe in which the gravity/quantum conundrum has been resolved completely: the boundary theory is purely quantum, it contains no gravity, but a being living in the interior will still experience gravity. Gravity in this universe is part of the holographic illusion.

Why Does Our Universe Have Three Dimensions?

Why Does Our Universe Have Three Dimensions? | Science News | Scoop.it
Why does our universe look the way it does? In particular, why do we only experience three spatial dimensions in our universe, when superstring theory, for instance, claims that there are ten dimensions -- nine spatial dimensions and a tenth dimension of time?

Japanese scientists think they may have an explanation for how a three-dimensional universe emerged from the original nine dimensions of space. They describe their new supercomputer calculations simulating the birth of our universe in a forthcoming paper in Physical Review Letters.
