Abstract
For the past decade there has been a considerable debate about the exi stence of chaos in the mixmaster cosmological model. The debate has be en hampered by the coordinate, or observer, dependence of standard cha otic indicators such as Lyapunov exponents. Here we use coordinate-ind ependent, fractal methods to show the mixmaster universe is indeed cha otic.
