Some physicists think our reality is a kind of cosmic hologram, with space, time, and gravity as manifestations of a ...

One could just as easily argue that, if the holographic principle turns out to be useful, then we have merely discovered a powerful—and even vital—mathematical tool for understanding our universe.

A holographic universe, an idea first suggested in the 1990s, is one where all the information, which makes up our 3D 'reality' (plus time) is contained in a 2D surface on its boundaries.

First, a quick recap: Holographic duality can show us what's inside a black hole because it suggests the 2D universe is connected to the 3D universe via mathematics. We just have to construct an ...

Some physicists actually believe that the universe we live in might be a hologram. The idea isn’t that the universe is some sort of fake simulation out of The Matrix, but rather that even though ...

Indeed, the holographic bound deduced from black holes must break down in a uniform expanding universe. The entropy of a region uniformly filled with matter and radiation is truly proportional to ...

By John Timmer, Ars Technica The proponents of string theory seem to think they can provide a more elegant description of the Universe by adding additional dimensions. But some other theoreticians ...
