Introduction: a homogeneous<br />
or fractal universe<br />
• Usual assumption: <strong>the</strong> <strong>Universe</strong> is homogeneous and isotropic on large <strong>scale</strong>s<br />
• Homogeneous regime is not realised on small <strong>scale</strong>s, due to <strong>the</strong> <strong>for</strong>m <strong>of</strong> <strong>the</strong><br />
spectrum <strong>of</strong> matter perturbations and to <strong>the</strong>ir evolution via gravitational collapse.<br />
• <strong>The</strong> primordial spectrum <strong>of</strong> metric perturbations is predicted to be almost<br />
<strong>scale</strong>-invariant by inflation, still expect some level <strong>of</strong> inhomogeneities<br />
