comment Why does only one side of a neon lamp glow?
Can you summarize your reference instead of just linking? Your reference says "A neon display lamp uses the positive column for its light", which would seem to mean the positive end glows, which is not the case in reality.

comment Why does only one side of a neon lamp glow?
As I pointed out in another comment, the talk page of Wikipedia:Glow discharge says "Sputtering of the cathode, on the other hand, is not at all important for a glow discharge. It is merely a side effect." Also the neon lamp article says that sputtering wears the electrodes and darkens the lamp over time by coating the surface of the glass with metal.

comment Why the galaxies form 2D planes (or spiral-like) instead of 3D balls (or spherical-like)?
"Stars also do not collide"? How so? Even if they don't collide head-on, but pass each other somewhat closely, they will both be deflected by each other's gravitational field.

comment Would wearing clothing that is black on the inside and white on the outside keep you cooler?
@mukunda: Yes, a white trashbag and nothing else. That will make you cool no matter what the season.
