One-Minute Physics: Are unknowns part of the universe?

Sandrine Ceurstemont, editor, New Scientist TV

What's part of the universe? You may think of it as incorporating everything that exists - both on Earth and in space - but could it also include the unknown?

In this One-Minute Physics episode, film-maker Henry Reich delves into the notion of the universe as described by physics, distinguishing between the whole universe and what's observable. He looks at the three components of the universe that we are sure of and whether mathematics could be included or not. Then there is the concept of parallel universes that could extend our understanding of space.
