# A BALLOON PRODUCING BALLOONS, PRODUCING BALLOONS:A BIG FRACTAL

*Think about it this way: Previously, we thought that our universe was like a spherical balloon. In the new picture, it's like a balloon producing balloons, producing balloons. This is a big fractal. The Greeks were thinking about our universe as an ideal sphere, because this was the best image they had at their disposal. The 20th-century idea is a fractal, the beauty of a fractal. How many different types of these elements of fractals are there, which are irreducible to each other? The number will be exponentially large; in the simplest models, it is about 10 to the degree 10, to the degree 10, to the degree 7. It actually may be much more than that, even though nobody can see all of these universes at once.*

ANDREI LINDE, a Russian-American theoretical physicist and professor of physics at Stanford University, is the father of "eternal chaotic inflation," one of the varieties of the inflationary multiverse theory, which proposes that the universe may consist of many universes with different properties. He is an inaugural winner of the $3 million Fundamental Physics Prize, awarded by the Milner Foundation. In 2002, he was awarded the Dirac Medal, along with Alan Guth of MIT and Paul Steinhardt of Princeton University. **Andrei Linde's Edge Bio Page**
