Corrected entry: How in the heck someone like in Doctor Phlox's time frame knew anything about tribbles in the first place. It was 100 years before McCoy and Cerino Jones and 200 years before Worf and co. Guess Doctor Phlox can leave a note to Doctor McCoy about the tribble's life cycle and its predators.
Corrected entry: In the episode "Regeneration", how can the two borg that regenerate communicate, as you will know from the Voyager episode (Survival Instinct) for instance, drones that are severed from the collective (as these had been for 100 years) do not re-establish connections with each other. They only act as confused individuals. They can't have been in contact with the collective. If they were, it would not have been necessary for the drones to send the message to the collective at the end. We know that the original two drones were from the future, and therefore, if they were in contact with the present-day collective, the Borg would have tried to attack earth long before TNG.
Corrected entry: In 'Regeneration,' the doctor manages to find a way to defeat the Nanoprobes. These are 24th Century Nanoprobes that no scientist or doctor from that era can defeat. Yet he can do it whilst under the Nanoprobes effect (i.e., he is not operating at full strength) and in only a few hours. Maybe he should leave a note for Dr. Crusher to tell her to try that radiation out?
Corrected entry: In the episode "Regeneration", towards the end of the episode there's a scene where several Enterprise crewmen are being pursued by several borg. The crewmen fire their phase pistols at the borg and two of the drones are hit and dies and then when the next two drones are hit they have developed shields against this phaser setting. In the next scene we see Archer and Reed on the transport ship that the borg is modifying and they are shooting and killing drones right and left continously without any of the drones adapting their shields. This is long before Picard and Janeway so naturally nobody, not even Reed, has learned that they have to alternate frequencies on the phasers in order to keep the borg from adapting while on the other hand the borg are all interconnected so when the drones on the Enterprise developed shields so should the drones on the borg ship.
Corrected entry: This series plays long before Star Trek TNG, so how come Starfleet has forgotten all about the Borg. In the TNG series the Borg are discovered and Starfleet has no information about them. Surely someone should have mentioned something about them in the Starfleet archives.
Corrected entry: In "Horizon" they talk about going to visit a system to watch a geological event that will take place in a week from then. Mayweather says that this system is 30 lightyears away from them. By using the Warp speed calculator http://www.ussdragonstar.com/utilitycore/warpspeeds.asp you see that this trip would take about 51 days. Warp 5 is too slow to get there in time, but still they arrive in time.
