comment What percentage of visual stars are actually binary stars?
Point of clarification: "Double stars" refers to two stars that are visually very close together so they appear as one by the naked eye. But that doesn't necessarily mean they are binary stars. Do you have a preference?

comment golden and red colored light even after Sunset
The "golden hour" is a term used in photography — en.wikipedia.org/wiki/Golden_hour_%28photography%29. While it is caused by the scattering and refraction of light in the atmosphere, this isn't really on topic for a site about astronomical observations and astrophysics. You may want to try the Photography site, or possibly Physics SE. Sorry about the confusion. Good luck!

comment How many earths fit in the observable universe?
Your answer assumes we are pulverizing the earth to completely fill the volume of a universe-sized container. Without getting into the complicated math behind forming optimal latices of congruent spheres, you should multiply your answer by a factor of pi/(3*sqrt(2)) or about 0.74048. The Kepler Conjecture says that is the highest density that can be achieved by any arrangement of spheres. Oh, and since the observable universe is also expanding at an accelerated rate, you should also update your answer every few hundred millions years just to be safe. Just saying.
