According to Tegmark, “there is only mathematics; that is all that exists.” In his theory, the mathematical universe hypothesis, he updates quantum physics and cosmology with the concept of many parallel universes inhabiting multiple levels of space and time. By posing his hypothesis at the crossroads of philosophy and physics, Tegmark is harking back to the ancient Greeks with the oldest of the old questions: What is real?
Tegmark has pursued this work despite some risk to his career. It took four tries before he could get an early version of the mathematical universe hypothesis published, and when the article finally appeared, an older colleague warned that his “crackpot ideas” could damage his reputation. But propelled by optimism and passion, he pushed on.
"I learned pretty early that if I focused exclusively on these big questions I’d end up working at McDonald’s,” Tegmark explains. “So I developed this Dr. Jekyll/Mr. Hyde strategy where officially, whenever I applied for jobs, I put forth my mainstream work. And then quietly, on the side, I pursued more philosophical interests.” The strategy worked. Today a professor at the Massachusetts Institute of Technology, Tegmark travels among the world’s top physicists. Backed by this well-earned credibility, his audacious ideas are sparking fascination and taking flight.

Is the Universe All Math?
Discover Magazine has an interesting article, Is the Universe Actually Made of Math, by Adam Frank, theoretical astrophysicist at the University of Rochester in New York. It is an interesting article that is mostly an interview with Max Tegmark, discussing Tegmark's ideas. Tegmark is a cosmologist at MIT:
