The universe from a hologram?

New research into the emergence of space and time has revealed evidence that the universe could have emerged from a two-dimensional “hologram.”

An international team of researchers from Canada, the UK, and Italy recently proposed in Physical Review Letters a model of the early universe very different from the world of our everyday experience.

In this video, Perimeter Institute researchers Niayesh Afshordi and Elizabeth Gould explain that a two-dimensional holographic model may help us understand what happened at the start of it all.

MERA and holography – or maybe not

For a decade, physicists have been asking a tantalizing question: could a mathematical tool lifted from condensed matter physics be the unlikely key to a better understanding of holography? Now the answer is at hand – and it’s not what anyone expected.
