The Holometer: A Fermilab Experiment

Do we live in a two-dimensional hologram? A group of Fermilab scientists has designed an experiment to find out. It’s called the Holometer, and this video gives you a behind-the-scenes look at the device that could change the way we see the universe. Find out more at http://holometer.fnal.

Why do some scientists believe that our universe is a hologram?

In this video, I explain why some scientists believe that our universe is a hologram and we really live in the 2-dimensional projection of a higher dimensional space. First, I explain just what physicists mean by the "holographic principle." The holographic principle says that the degrees

What are domains of holomorphy?

We define domains of holomorphy in C^n. We introduce holomorphically convex domains. We state the Cartan-Thullen theorem, and list consequences. One if them provides the existence of a smallest domain of holomorphy containing a fixed domain. For more details see Hormander's "An introducti

There are many ideas rattling around the theoretical physics community that are a bit outlandish, but one stands out. This is the idea that our universe is actually a hologram. In this episode of Subatomic Stories, Fermilab’s Dr. Don Lincoln sketches out the theory of the holographic uni
