The universe we live in might be a hologram
Over at VOX, Joseph Stromberg explains how the universe we live in might be a hologram.
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 we appear to live in a three-dimensional universe, it might only have two dimensions. It’s called the holographic principle.
The thinking goes like this: Some distant two-dimensional surface contains all the data needed to fully describe our world — and much like in a hologram, this data is projected to appear in three dimensions. Like the characters on a TV screen, we live on a flat surface that happens to look like it has depth.
It might sound absurd. But if when physicists assume it’s true in their calculations, all sorts of big physics problems — such as the nature of black holes and the reconciling of gravity and quantum mechanics — become much simpler to solve. In short, the laws of physics seem to make more sense when written in two dimensions than in three.
