When Lt. Ramirez's Starfury returns to Babylon 5 after being shot up, the incoming jump point is yellow. In the Babylon 5 universe, incoming jump points are blue - outgoing ones are yellow.
In an argument about baseball, Dr. Stephen Franklin states, "...Martian gravity is 40 percent less than (i.e., 60% of) Earth normal. The ball travels faster and further..." Martian gravity is even weaker than that at a bit under 2/5 of Earth's, not 3/5 as Franklin says (of note, it is true that in lower gravity, a ball hit at a given speed and angle takes longer to reach the peak of its arc, and thus covers more horizontal distance, in proportion to the difference in gravity).
