I make a number of comments about Smolin's theory of Cosmic Natural Selection.

4 Cardy - Verlinde Formula and Holographic Dark Energy

If we separate energy in a holographic theory into an extensive part and an intrinsic part, where the extensive part is given by the cosmological constant, and assume entropy be given by the Gibbon-Hawking formula, the Cardy-Verlinde formula then implies an intrinsic part which agrees with a term recently proposed by Hsu and Zee. Moreover, the cosmological constant so derived is in the form of ...

In this astro-particle lecture course I shall try to emphasize evidence of the new physics which we have in cosmological and astrophysical data. This includes support of the inflationary model, necessity of dark energy and of non-baryonic dark matter, the Grizen-Zatsepin-Kuzmin puzzle of the ultra-high energy cosmic rays.
