 Oct 31 comment How many bytes can the observable universe store? Does the existence of dark matter, dark energy have any effect on the answer? Or is it a different question? Oct 31 awarded Nice Question Sep 24 awarded Autobiographer Mar 11 awarded Popular Question Dec 24 comment Calculate exact time of Solar midnight related: Local solar time function from UTC and longitude gives answer for the opposite direction: real time -> solar time. Compute shadow length using PyEphem demonstrates how to find semi-programmatically the next (real) time from sun_altitude(time) = known_altitude equation.

Jan 29 awarded Student Jan 29 comment How many bytes can the observable universe store? @space_cadet: yes, the questions are very similar, but 1. @tylerl's question explicitly requires 3D ("without assuming more dimensions") Could additional dimensions be used? 2. The second difference is additivity: do 10 cc contain 10 times more information exactly (or there could be an interaction that allows more than 10 times)? 3. Does the the accepted answer physics.stackexchange.com/questions/2281/… is the only possible approach? Jan 29 comment How many bytes can the observable universe store? Is it a coincidence that this is similar to an estimation: {number of possible baryon states}^{number of baryons} i.e.,constant^{10^80}. Jan 28 asked How many bytes can the observable universe store?
