If Warp 10 were supposed to be infinite speed, wouldn't that mean that at Warp 10, you could traverse an infinite distance, instantly?That portion of All Good Things was set in the future. An essentially throwaway reference intended to make things sound more futuristic.
Nothing more, nothing less.
Gene Roddenberry had imposed the Warp 10 limit as "infinite speed" at the beginning of Star Trek: The Next Generation. Should we ignore the references to Warp 13 in "All Good Things..."?
Could the Warp 13 figure be evidence that Starfleet starships in the future use transwarp or quantum slipstream drives to get past the Warp 10 barrier? Or we could speculate that the Warp Factor chart was revised again sometime before 2395.
But how then do you go from 9.999, which has a set travel duration, to 10.0, and have it be infinite?
I'm just not getting why Warp 13 is a problem. 10.0 must be a specific speed, maybe a theoretical limitation, but once traversed, you need to increase the numbering.
Limits? Any type of exponential function? You don't go from 9.999 to 10, you go from 9.999 to 9.999 and then to 9.999 such that your speed reaches infinity when your warp factor reaches 10. For a super simple formula, think about V = 9c/(10-W). At W=1 your velocity is equal to c, the speed of light. As W increases your velocity increases. At W = 10 you would have a divide by 0 and infinite speed, but as W gets closer and closer to 10 your speed increases dramatically without W ever reaching 10. As others have explained, once starships started to routinely go at Warp 9.999 it began to become cumbersome to talk about speeds like that, so the formula was changed to something like 14c/(15-W). Warp 1 still equals the speed of light, but now you have 15 numbers until you reach infinite, and Warp 13 is really something like Warp 8.71 on the old scale. Of course the actual formula is probably slightly more complex and would provide more granular differences at slower speeds, but it gives you a rough idea of how it could work.
