The Multiverse Has 11 Dimensions
Michio Kaku is a futurist, popularizer of science, and theoretical physicist, as well as a bestselling author and the host of two radio programs. He is the co-founder of string field theory (a branch of string theory), and continues Einstein’s search to unite the four fundamental forces of nature into one unified theory. He holds the Henry Semat Chair and Professorship in theoretical physics and a joint appointment at City College of New York and the Graduate Center of C.U.N.Y. He is also a visiting professor at the Institute for Advanced Study in Princeton and is a Fellow of the American Physical Society.
Kaku launched his Big Think blog, "Dr. Kaku's Universe," in March 2010.
Question: Are there only three dimensions in other universes or could there be more? (Submitted by Andre Lapiere)
Michio Kaku: Andre, we believe, though we cannot yet prove, that our multiverse of universes is 11-dimensional. So think of this 11-dimensional arena and in this arena there are bubbles, bubbles that float and the skin of the bubble represents an entire universe, so we’re like flies trapped on fly paper. We’re on the skin of a bubble. It’s a three dimensional bubble. The three dimensional bubble is expanding and that is called the Big Bang theory and sometimes these bubbles can bump into each other, sometimes they can split apart and that we think is the Big Bang. So we even have a theory of the Big Bang itself. Now you ask a question what about the dimensions of each bubble. Well in string theory—which is what I do for a living; that's my day job—in string theory we can have bubbles of different dimensions. The highest dimension is 11. You cannot go beyond 11 because universes become unstable beyond 11. If I write down the theory of a 13-, 15-dimensional universe it’s unstable and it collapses down to an 11-dimensional universe. But within 11 dimensions you can have bubbles that are 3 dimensional, 4-dimensional, 5-dimensional. These are membranes, so for short we call them branes. So these branes can exist in different dimensions and let’s say P represents the dimension of each bubble, so we call them p-branes. So a p-brane is a universe in different dimensions floating in a much larger arena, and this larger arena is the hyperspace that I talked about originally.
Also remember that each bubble vibrates, and each bubble vibrating creates music. The music of these membranes is the subatomic particles. Each subatomic particle represents a note on a vibrating string or vibrating membranes. So, believe it or not, we now have a candidate for the "Mind of God" that Albert Einstein wrote about for the last 30 years of his life. The "Mind of God" in this picture would be cosmic music resonating throughout 11-dimensional hyperspace.

The physicist explains why other universes in the mulitverse could have many more dimensions—and could comprise Einstein's "Mind of God."
California wildfires death toll climbs to 50
Firefighters in California are still struggling to contain several wildfires nearly one week after they broke out.
- Hundreds of people are still missing after three wildfires spread across Northern and Southern California last week.
- 48 of the 50 deaths occurred after the Camp Fire blazed through the town of Paradise, north of Sacramento.
- On Tuesday night, a fourth wildfire broke out, though it's mostly contained.
Too much sleep results in cognitive decline, researchers find
We know the dangers of too little sleep. Now for the other side of the story.
- Western University researchers found that sleeping over eight hours per night results in cognitive decline.
- Oversleepers suffer similar difficulties on certain cognitive tests as those who sleep under seven hours.
- Not all the news is bad: One night of oversleeping results in a cognitive boost.
