'Crossing the Void' graphic

<div>This is an original graphic I did for the 'Spaceflight' page of the doc to illustrate how FTL travel works in the SF universe, with the trip broken down by elapsed time, distance traveled, velocity over the course of travel, and gravity experienced on ship during the phases of flight. I found a Star Trek Warp Factor chart later and the Void portion of the trip comes out to around Warp 6... :)</div><div><br /></div><div>The silhouette of the ship is the destroyer from the KH book. The starfield in the background is from a galaxy far, far away...<br /></div><div><br /></div><div>Here's the text from the document that goes with the graphic:</div><div><br /></div><div><span style="font-size: 7pt; font-family: Helvetica">&quot;The graphic below shows an example voyage from the Timeon system to Prenglar, an established spacelane with 8 Light Years of separation between stars.

Passengers aboard the ship will feel that their senses are very distorted; colors and sounds will be unfamiliar, the sense of touch will seem to vanish completely...the experience can be very disorienting!
