The natural world. Looking pretty for 3.5b years.

The Universe, as Hologram

The Universe, as Hologram

Physicists continue developing the idea that our universe is, at core, two dimensional

Author: Trevor Quirk/Tuesday, April 28, 2015/Categories: space science, art and design

Thanks to Brian Greene and Neil deGrasse Tyson, many know that current theoretical work in physics suggests that the universe can be considered to have 10 dimensions (or more, depending on your particular subscription of String Theory.)

Less publicized, though, are ideas that universe is fundamentally constituted of less dimensions that the number we experience: three (or, four, if you included time.)

This April, physicists have published a paper that suggests that our universe is made of only two dimensions, truly, and that our 3D perception can be explained by the "holographic principle," which posits our three-dimensional world is the image of two dimensions projected on a cosmic horizon. Check out Science Daily's in-depth treatment for further explanation.

It's hardly a definitive theory, but it's fun to be alive while physicists explore the overlap between these models and reality.

That's really amazing. I'm pretty sure I don't understand it, but I love stuff like this.
