	To reach this number, clues are taken from [[Billy Keikeya]], on ''[[Colonial Heavy 798]]'', enroute to the battlestar for its decommissioning ceremony. Keikeya tells [[Laura Roslin]] that he had sent a copy of her ceremony speech to President [[Richard Adar\|Adar]] for review, but warns that there is a time delay of 30 minutes between ''Galactica'' and Adar's actual location, which is [[Epiphanies\|confirmed]] as Caprica City, the seat of the Colonial [[Government]] <ref name="jack">President Adar's office on Caprica is confirmed in the second Season episode, "[[Epiphanies]]". Reinforcing this information, Roslin speaks by [[wireless]] to "[[Jack]]", a fellow secretary or government official. Jack tells Roslin of the devastation near his location and Adar's speculated whereabouts and actions. Given that wireless transmission ranges in real-time conversation would limit Roslin to be able to speak only with Caprica (the nearest colony), Jack must be on Caprica, and likely in Caprica City to give him any ability to discuss the president's whereabouts.</ref>.

	The speed of light (and of wireless transmissions) in vacuum is 186,282 miles per second. If President Adar sent a [[wireless]] message from Caprica to ''Galactica'' in an attempt to correct Roslin's speech, how long would it take the message to get there? Keikeya gives this answer: 30 minutes. This makes it possible to determine the distance using the equation: ''s = vt'' (or, ''distance = speed x time'')		The speed of light (and of wireless transmissions) in vacuum is 186,282 miles per second.

	Based on deduction from information gleaned in "[[Scattered]]", a set of jump coordinates could either be given in [[w:Cartesian coordinate system\|cartesian]] or [[w:Spherical coordinate system\|spherical]] coordinates to specify a point in three-dimensional space.		Based on deduction from information gleaned in "[[Scattered]]," a set of jump coordinates could either be given in [[w:Cartesian coordinate system\|cartesian]] or [[w:Spherical coordinate system\|spherical]] coordinates to specify a point in three-dimensional space.

	A possible algorithm for jump calculations would therefore necessitate first and foremost the determination of the exact location of the ship, relative to its intended point of arrival after the jump. This is done by identifying, fixing and triangulating several stars <ref name="tighquote"/>. Next, the ship's position relative to the intended point of arrival would be [[w:Point plotting\|plotted]] on a three-dimensional coordinate system, using the ship as its [[w:Origin (mathematics)\|point of origin]], i.e. (0/0/0).

	At first glance, this seems counter-intuitive. Since presumably both sets of jump coordinates are known to ''Galactica'', a simple triangulation of the two jump vectors would produce an alternative third set of jump-coordinates which would allow ''Galactica'' to jump to the Fleet directly. A possible explanation is as follows:		At first glance, this seems counter-intuitive.
