Moreover, the main problem may be that energy is not conserved in GR. In usual thermodynamics changes in entropy are related to changes in energy of a system.So all such arguments may be ambiguous.kashyap vasavadahttps://www.blogger.com/profile/10732897306667764590noreply@blogger.comtag:blogger.com,1999:blog-22973357.post-60639892616890312722015-06-12T07:11:36.876-04:002015-06-12T07:11:36.876-04:00"... cyclic cosmological models viable altern..."... cyclic cosmological models viable alternatives to inflation ..." First, IMO, inflation is now an established empirical fact — the only question is whether it is Newtonian-Einsteinian inflation or Milgromian inflation. Second, Milgrom is the Kepler of contemporary cosmology — based upon the evidence.<br /><a href="http://arxiv.org/pdf/1301.3907v1.pdf" rel="nofollow">“The failures ofDavid Brownhttps://www.blogger.com/profile/10537922851243581921noreply@blogger.comtag:blogger.com,1999:blog-22973357.post-34248296990939680512015-06-09T19:46:24.074-04:002015-06-09T19:46:24.074-04:00http://math.ucdenver.edu/~wcherowi/courses/history...<a href="http://math.ucdenver.edu/~wcherowi/courses/history2/hmsine.html" rel="nofollow">http://math.ucdenver.edu/~wcherowi/courses/history2/hmsine.html</a><br /><br />Quote:<br /><br />The English word “sine” comes from a series of mistranslations of the Sanskrit jya-ardha (chord half).
