So we should expect to see traces of that original furnace in the night sky, and indeed we do. Background radiation, speÂ�cifiÂ�cally the presence of microwaves, demonstrates the remains of an initial firestorm that included evÂ�eryÂ�thing. 16 The data from WMAP show evidence of very small irregularities in the earliest visible universe. As matter in the denser areas condensed, these irregularities probably allowed for the formation of stars and galaxies.

This realization has to do with the second law of thermodynamics, which I mentioned briefly in the last chapter. Entropy can only increase or stay the same. In the vernacular of science, entropy meaÂ�sures the amount of order or usable energy in a system. Any closed system will either maintain its orÂ�gaÂ�niÂ�zaÂ�tion or lose orÂ�gaÂ�niÂ�zaÂ�tion with time. This section goes into a little more detail about how entropy works and what it tells us about time symmetry in the cosmos. Let us return to our thought experiment in Chapter 3 about the deck of cards.
