      XPost: sci.astro.research       From: helbig@asclothestro.multivax.de              A smooth distribution corresponds to high entropy and a lumpy one to low       entropy if gravity is not involved. For example, air in a room has high       entropy, but all the oxygen in one part and all the nitrogen in another       part would correspond to low entropy.              If gravity is involved, however, things are reversed: a lumpy       distribution (e.g. everything in black holes) has a high entropy and a       smooth distribution (e.g. the early universe) has a low entropy.              Let's imagine the early universe---a smooth, low-entropy       distribution---and imagine gravity becoming weaker and weaker (by       changing the gravitational constant). Can we make G arbitrarily small       and the smooth distribution will still have low entropy? This seems       strange: an ARBITRARILY SMALL G makes a smooth distribution have a low       entropy. On the other hand, it seems strange that the entropy should       change at some value of G.              --- SoupGate-Win32 v1.05        * Origin: you cannot sedate... all the things you hate (1:229/2)    |
