The theory that the universe is a hologram explained in under 5 minutes Listen to the first episode of our new podcast where scientist Matthew Headrick explains one of the most mind-blowing ideas in physics. Nov. 8, 2018Below is a transcript of the episode.
LAWRENCE GOODMAN, HOSTWelcome, everybody to what is the first ever — the inaugural episode — of the new Brandeis University podcast, “The Take: Big Ideas Explained in Under 5 Minutes,” where professors explain core concepts of their research in under five minutes.I’m Lawrence Goodman with the Office of Communications. With me today is Brandeis University associate professor of physics Matthew Headrick, who is here to explain what is really a mind-blowing theory in physics, the idea that the universe is a hologram. It’s also called the holographic principle.And this is a real theory. It’s not science fiction and Professor Headrick is an expert in it.
So thank you very much for joining us.ASSOCIATE PROFESSOR OF PHYSICS MATTHEW HEADRICKGreat to be here.HOST: So let’s start at the very beginning. In a nutshell, what is the holographic principle?HEADRICK: Well, as you said, the holographic principle is the idea that the universe around us, which we are used to thinking of as being three dimensional — we have three dimensions of space — is actually at a more fundamental level two dimensional and that everything we see that’s going on around us in three dimensions is actually happening in a two-dimensional space.HOST: Great. So let’s break it down even further. This two-dimensional plane, what’s it made of? It’s made of what you call information?HEADRICK: Right. So similarly to the bits and bytes that live on a compact disc, which encode, for example, a piece of music — on this plane, that’s where the bits that fundamentally make up our universe live. That’s where they’re encoded and what they’re encoding is …
